Wow that thing is small... or your hands are real big,lol

Where did you buy from? Im looking into getting it from moore racecraft. We should get a gp together maybe save a few bucks.

hey guys I wanna get one of these units too cause I love the idea of the self tuning I just have a question if I use the holley stuff can I just do away with the stock computer and the harness for it? thanks for your reply and that car sounds sick!!

iTrader: (4)

yep pull out the stock wiring harness and computer and replace with the holley stuff.

If this is referring to the '91 and it is a TPI set up, you will lose the speedometer and cruise control when removing the stock ECM.

Did you run electric fans though one of the four outputs on the Holley or is that a feature built into the unit?
On a 88 Iroc Z does the cruise control go though the computer since it has a mechanical speedo?
Should the tach still work if you you swap to a holley hp efi on an 88 It seem like his did on the video or did you modify something?

wilnuts88

Yes, you have to use one of the four outputs for the fans. No the cruise control does not go through the computer, it will still work. Yes the tach will work without any issues. I can say all of these things because my car is running great on my hp.

iTrader: (4)

That's awesome I'm about to swap to Holley efi going from tpi to holley stealth ram and I want to keep all my acc working, a/c, cruise, & fans.

Did you have a tpi set up and use the 550-601 kit. If so do you run across any issues work mentioning?

What all inputs and ouputs did you use?

Did you keep lockup on your 700r4 lockup?
If so did that run though the holley?

I got one of these systems recently but I'm still building my 383 so I can't test it yet.

I've got some questions though!

There is no plug for a MAF. Am I correct in thinking that this system eliminates the MAF and uses the MAP instead?

Can someone clarify how to hook up my fans? Do I send an output to the fans and then somehow tell the EFI that that output is going to my fans? I haven't looked at the tuning software yet so I don't really know how this works.

What about my AC? Does this system care to know about when my AC comes on or off? Would I just do the same thing for the fans if it does?

Also, what is the grey box in the middle of the picture seen here: http://www.holley.com/data/products/...rge550-601.jpg

I can't figure out what it does or where it goes.

Any help would be appreciated!

thatsupnow

that grey box "thing" is the map sensor its a speed density system you plug the connector into it and a vacuum line from the manifold. the harness should have everything labeled clearly. Im kinda wondering how you would go about getting the electric speedo to work along with cruise control??

IROCZ1989

iTrader: (1)

Hi I just got my system about 2 weeks ago. I have my fans tied in series with one ground that will activate them, used to use a fan switch in the head. You need an imput/output harness,the kit doesnt come with one. It has the connections to control tcc,fan,meth inj,nos. With the imput/output harness you ty in the corresponding wire ans set that output to ground, then in the software you specify the temps.on/off. Now you can do 2 fans idependant of each other just split the grounds.Ac I dont know knothing about. Have you even started hooking up the system yet? I dont have my factory harness anymore. I got mine hooked up in a day or so. Grey is the map senso no more mass air.

Camaero

iTrader: (2)

No more MAF? Cool. I didn't even realize that when I ordered it. I haven't started hooking anything up yet but I plan to begin later today and tomorrow. I want to make sure everything is perfectly ready by the time the 383 is done.

Thanks guys! That helps a hell of a lot.

Anyone know how the check engine light works with this system? I need that to be more or less functional for smog reasons.

iTrader: (4)

I didnt lose the speedo when I removed my stock ECM? Is this a TPI specific thing?

RBob

iTrader: (1)

Yes. The '90 - '92 TPI & MPFI ECM (same one, the '7730), the ECM buffers the VSS signal.

RBob.

InfernalVortex

iTrader: (4)

weird... good to know, as I intend to do an EFI swap sometime soonish..

So if I run my VSS signal to an SGI-5 box and then to my speedo, I will still have a working speedo. But the 7730 ecm "buffers the signal"... does that mean the ecm needs the vss signal to function properly? Or does that mean something else?

Camaero

iTrader: (2)

Will the MAT and Coolant sensor I already have work? Aren't those the two they provide (besides the MAP)?

Bump on my last question there and I've also got a new one:

How do you hook up Holley's (or any aftermarket) gauges?

Camaero

iTrader: (2)

Bump ^^^

scooter

iTrader: (11)

Your question isnt very specific, but there is nothing to hook up but the tach and thats is in the instructions, thats probably why you havent gotten a response

Camaero

iTrader: (2)

Sorry,

I meant how do you set up Holley's digital gauges through Holley's ECM? I thought I saw somewhere that it was easy to change what each gauge is showing. For instance you could easily have a gauge show fuel pressure, boost, or whatever and switch between them?

I pretty much figured out how to set up the inputs but to output that information to gauges is another story.

IROCZ1989

iTrader: (1)

It should be there already. I actually got 2 more 100psi holley transducers to moniter oil and fuel pressure. The gauges are supposed to be more fluid with the screen they offer btw. I just got my whole setup installed just waiting on a duel sync harness from Moore racecraft to finish it off. I plan on running duel knock sensors as well. You can buy a vortec cam sensor harness i believe that plugs right into the holley harness with no splicing. Then you tap off that. Take care

IROCZ1989

iTrader: (1)

How did you make out Travis? System is so simple to install. Just waiting on my brake lines then i can put in my drivers side header (again). Hopefully there here soon.

thatsupnow

I was wondering if the '730 ecm buffers the vss signal is it possible to just install a vss buffer box in between the trans and speedo? and would it work again or is there more to it than that? Of course after figuring out which wire the signal is coming from the vss to speedo? And if thats the deal is the buffer box a 4000 ppm?

traviz, how are you liking this now that you have it for about 18months? i'm looking at the HP/Dominator for my car

IROCZ1989

iTrader: (1)

Id say id go with it. Got mine running in a day could have been an half hour though,Was my problem. Timing was off ,had setup the duel sync from fast wrong and after using a smoke machine found my tpi air plate was loose contributing from a vacume leak. Dennis Moore from Moore racecraft is about the only guy Id recommend talking to and buying off. He and another guy from Holly designed the system. Right now Im finalizing the wiring on the lockup and havnt had a chance to run it on the street , that's next week. But its a quick startup, very user friendly and I got my idle down quick. Defiantly look into the dominator if you have an elect transmission and or more than the hp offers in terms of inputs outputs. Im planning getting one for another vehicle i built a motor for with a 4l60e. Tell Dennis Darren sent you if you call. He is knowledgeable as hell and he's in New Jersey don't know if that's local to you. Hope that helps. Take care

iTrader: (13)

thanks for the info! yeah, i'm in GA, so that's not local, but thanks for the heads up on a good place to get it! then i can be sure to have a good tech support

scorp508

I'm happy to see you've had some great experiences with the HP unit. I'm considering one for my '87 Corvette's L98 so I can ditch the chips and emulators while getting into something a bit better than 25+ year old tech.

The lovely Atari dash has me wondering how many different damn things I'll lose. I'll have to break out the schematics book and see how much goes through the ECM. I'd rather not, but if I have to build some kind of piggyback harness just to get some data into the stock ECM and back out to the dash then it may have to be done.

I also have the Doug Nash 4+3 transmission, so I'll either have to re-wire it for manual activation (it's based off an ECM program now) or see if I could use the converter lock-up functions to enable it.

Keep the updates coming!

mw66nova

iTrader: (13)

from what i'm to understand, the in/out functions on the hp/dominator can be made to control any circuit base on any input (ie, time, rpm, ect.)

i don't know about the corvette, but the fbody gauges in 87 were all analog...sensor straight to gauge. also, the berlinetta's with the digital dash were the same way. even though the readout was digital, the functions were still analog.

IROCZ1989

iTrader: (1)

Yes you are correct. The dominator does alot more input outputs than the hp. But the hp is more than enough for most, except if you have an electronic transmission . Saves the cost and space of buying a separate unit. Basically all your gauge sender wires come out of the C100 drivers side harnes. Gm Helm manual is a godsend if you pull out the ecu or need to track wires. Its the best tool in my box. I think if you are in the market look well into the holly stuff. Fast, Accel and such have been out a few years, and from what I've been reading and first hand experience and with friends experiences Accel tech just plain sucks, if you don't believe me call them up. I called them about a simple injector recommendation a while back before I purchased anything and they told me to call kinsler. Friends have had nightmares and empty pockets using Accel dealers. Don't hear much about fast in the thirdgen crowd. Dennis is most of the time around if he's not on the road racing and holly tech is there allday and on Sat too when im doing most of my stuff. So look long and hard do alot of googeling all three and you will see round about which way the wind blows with these systems.

iTrader: (2)

I've said it time and time again, you can call me anytime just like Dennis. I'm one of the top tuners in the country and have lots of references.
You've stated your problems many times. I appreciate you wanting to let others know but move on. Accels' tech and website is far better than ever, check it out for yourself.

And the fact is, except for the self learning, all the others in this class are still catching up to the Accel. FAST's "new" 2.0 just now has some of the driveability the Accel has had for years.
Remember, all these systems use pretty much the same boards with same amount of capacity. The difference is the software and the langauge in which it communicates with.
Accel went ot the top tuners years ago and said "Ok guys we can do the self learning stuff but we'll need to give up something else for the board space, what do you want to give up, some of the transient tables, the easy Nitrous table, some of the starting tables, the ability for a true VE?, What?"

Nobody could come up with anything.

I'll put the drivability of the Accel against anything out there today in this class, hands down.

IROCZ1989

With the price of these systems people need to know from end users, guys who actually paid out of there pockets for the systems what they think. Sorry i won't "let it go" your a dealer , you make money off what you sell. I never see you post anything in these forums but trying to steer people interested in aftemarket efi to go with Accel and specifically to talk to you. So to say you have a horse in this race is an understatement.

Like I said do research, Google all three systems and get back to us with what you see. Holly right now is leading interms of new users at the moment. Ford, chevy and dodge. Fast is a good system so is Accel. But the thing with Accel is they won't help you over the phone they want you to use a dealer which means higher total cost in the end. Technology moves fast so I don't know why Accel hasn't come out with their Dfi 8 yet they have been saying coming soon for years.

If you race talk to racers, run the pits see what they run. Do all your research. Last thing you want to do is follow someone's advice who is making out in the transaction.
Good sites to check: chevytalk , yellow bullet, holley and fast forums, etc. Not knocking Accel but there is more out there than them. And in my opinion prestolite which owns Accel most of there lines are garbage. Mr gasket , lakewood, quicktime flexplates ( which I had a problem with one right out of the box) and found it after i was trying to bolt the converter to the flexplate and one hole wasn't drilled right, thank god for right angle drills. There response: send it back. How about get it right before you package it. Call all three and go from there with the above suggestions. Take care

Funny how you pick the one page that's being updated. Did you go to the other pages, the one that tells you how to figure injector size? Or the one that has the Master EMICS listed? Of course not, then your point wouldn't have had the same impact would it. And by the way, I know most of those guys and they'd be happy to help as well.

I searched Accel and clicked Accel Dfi link thats what came up, simple. Clicked another link that's what came up. Anyone here can do that. Your point???? Sorry i don't go on lateral g forum never did so I cannot speak of the site. But I know from being a user here that you just push Accel as a dealer first and foremost. Can't knock you for that though everyone needs to make a living. Im happy with the Holley, and with Holleys line in general. I have alot of Holley products on my car and customer service is always there. Maybe you are taking my posts the wrong way. But to say Accel is hands down the best system out there is a bit of a stretch. Nothing in life is absolute as that.
I never lumped you into any category, i have always said and meant the company you are a dealer for lacks in more than a few areas to say the least. Never anything against you. I have Accel stuff on my car, super ram, cam tb. First super ram I owned leaked like a sieve but hey I got lucky this time, are you going to argue Accel never had issues with the super rams sealing up?

Shoot him or anyone a price and let them call up other dealers from other systems and see for themselves the price difference and what you are getting for your money. I can speak from experience,kit with a fast duel sync and the harness for imput outputs and Dennis throws in a harness to hook right from the Holley to the dis was still almost 300 south of 2. Now that's with Bosch wideband full sequential. With that imput ouput harness you can control tcc , fans, rev limiter etc. Basically anything you want. Saved money by not having to buy any kind of rpm switch to light my shift light, just make a custom output which you can do in the software.

No hard feelings, so no need to be condesending in your responses, I just call it the way I see it. The website links don't work, they don't work end of story. Website is **** poor compared to the others listed, anyone can see that. Take care.

For what it's worth I helped this guy to on his FAST for a very nominal fee. He obviously thought so as well.

http://www.lateral-g.net/forums/showthread.php4?t=35968

For the last time, I said the Accel will drive better than anything in this class. If you want lots of datalogging then buy a BS3, if you want traction control and lots of bells and whistles then buy a FAST.
But this will compete with even the Motecs when it comes to overall drivability, backed by more transient fueling tables than anything "in this price range". Got it?

And you keep beating a dead horse so I'll point out one other thing. You haven't missed too many opportunities to tell us how little you paid for your Holley setup. I'm sorry but I can't help thinking that was a big part of your consideration.

Thank you for your time.

With the driveability tuning on accel, how easy is it to dial those tables in? Looking at the factory tunes, theres a ton of stuff in there for driving that takes a long time to tune right and I'm worried starting from blank slate, complete scratch will be a nightmare. Taking the syclone v6 based tune and modding it for my 401 has been troublesome to say the least.

IROCZ1989

iTrader: (1)

Im sure if you got an Accel efi guy would supply some kind of base maps, most tuners do and help you from there. Speaking from experience with the Holley its base maps are close but the self learning pulls or adds lbs of fuel for stated rpm range based on afr required. If Im not mistaken though the Accel doesn't do boost control. I guess for the home tuner the Holley was the way to go for me. If you want to use Accel dealer network buy from them and let them tune it. These systems have been out so long that there is a base tune to get you close starting off and you tune from there, unless you have some crazy one off combo. Price has everything to do with manufactures tooling expenses and overhead bigger companies can charge less for simaler features. Cheaper doesn't always mean garbage, and expensive doesn't always mean its the best. Thing I like about dealing with Mooreracecraft is he helped design the system with another guy at Holley. He's always in touch with them about the product. Give them all a call. Only way to make educated decision is to talk to the companies , resellers or tuners , and lastly most important of all end users. You see after the money is paid that is when the product makes or breaks a company. If you stand behind it after you sell it its worth the money you paid. Take care.

Well its kinda unique Speier v2.72 heads, not many ppl running these since they just came out within last 2 years or so. Big custom hyd roller, not many running something this big. Its bigger than some solid rollers.

Its just that with the ultra high price of these EFI systems, alot of them come with so many features I do NOT need. I dont need traction control although it would be kinda cool, I dont think I'll need ability to drive a secondary set of injectors, etc. I just want something thats easier to interface with and flash tune rather than burn chips, and have more resolution than I do now to fine tune things. Alittle self learning for cruise and such would be awesome. I have done well with the stock oem stuff but I feel I have alot to be gained with proper control. So budgeting this down would be a huge plus. I spent enough on the engine and rear end, I dont see how a fuel management system is 2K+. I'm doing just fine with a 30 dollar ecm and free software

So as long as it controls fueling to an accurate degree and timing to an accurate degree, 3 bar boost capable, and has some good idle/startup controls and some driveability controls with %TPS, AE/PE modes, etc I'll be very happy

Download the software from holly and fast and accel and play with it. If you are concerned about getting it running I would defiantly go to a tuner , bypass anything over the phone. If you have alot of money in the engine I would bring it to a reputable tuner on a dyno.

Orr89RocZ

iTrader: (20)

I'm well versed in TPI tuning and know I can figure this stuff out. I'm very cautious in my tuning so no problems there.... just that I want to know how easy it is to get something up and running. If one system has more available base programs to help get things moving then I may go with that one due to time constraints. I want it up and running fast so I can start the tune process, not sitting around trying to figure out what does what and where to set numbers to be remotely close to being right.

I didnt know software was available for download. Will have to check that out. That could make or break my decisions.

IROCZ1989

iTrader: (1)

Couple of things to look into is if the ecu can update in real time. I know the holly you can change things while running. Datalog is very important too. Holly does both internal and external so you can log runs or laps. Best thing i like about the software is the self learning. If you plan on doing this yourself defy look into these systems that offer it. For example in my situation . I used there 225 base map, its for cams 215-225 dur. You punch in ci, inj size ,fp etc. What the self learn does is pull fuel or add depending on what afr you want, at idle,cruise, wide open throttle. I am def learning quite a bit about tuning,and to tell the truth is not diffixult once you get the software down. So best thing is do like I did. When i decided i wanted the holley, i downloaded the software and played with it nonstop. Its also runs a crank trigger if that might be something you want. It doesnt fit the l98 type block setup if your running serpintine though. anymore ? Just ask. Take care

M66nova, just noticed you have an lsx motor , i know holley and fast can run these with injector packs, the accel idk.

Hey there man Ive got this holley system too Ive been taking my time installing it wanna get it right first time thru. Ive just ripped most of the factory harness out. Ive got a question for you if you got time regarding the fans, lockup and fuel pump. Would I be able to just use the factory relays for those items and by just tying in the holley I/O harness and setting them to ground in the firmware with the laptop hooked up? And cut the wire for the lockup and tie that into the holley harness also?? thanks for your time and response.
