So I am looking to upgrade from my holley commander 950 to something a little newer. Looking for some opinions and options. I am interested in the Holley HP, EZefi 2.0 xfi sportsman, and maybe an accel one.

I want it to able to support boost, self learning and torque converter lockup. I don't think the ezefi one does boost without going to the xfi sportsman. Which is ok but i really like the screen the ez comes with.

No one I know that has used the EZ-EFI has been happy with it. I'm actually looking to help a friend swap his EZ-EFI to Megasquirt, likely MS3.

Don't exclude the new AEM Infinity. Probably the fastest processor out today and gobs of tuning and overall features.

I read a few threads saying that. The new 2.0 one looks pretty nice though. Just want to keep my options open.

I was looking at them also not a lot of info though. Pricing and harness and such. Nevermind there is a lot on that site almost to much.

I am looking for user experience as well. So post if your happy with one you are currently using.

I am currently running the EBL-P4, extremely satisifed with it, does everything that I need it to, and the features and upgrades keep coming. Another system that also impresses me is the ProEFI system that a lot of the GTR guys are going with, the display logger is pretty neat...

Been really impressed with holleys hp system. My buddy has one and got the car running 7's in just over a weekend. Thats how easy it was to setup and self learn to get it close. Fine tune from there

Ebl p4 is nice too if you can locate a speed density harness and ecm

Thats impressive. I'm really steering towards the holley at this point. I am happy with 950 I have now it wasn't hard to get running. Just looking for an up to date system. And one that's a little easier to tune after a minor or major change has been made.

The EBL looks nice I've looked into before but I would have to build a custom harness which wouldn't be to hard but I feel like its going back to stock. I know its not and you can modify almost anything you want with it. But you almost need to be a pro tuner to get it all right. I'm not knocking it I've read some great things about it I just don't think its what i am looking for.

Ebl base bins are really good. It honestly isnt hard to get dialed in

I got that 383 procharged car idling on near stockve table, some slight increase for the bigger motor and it ran great. 6-7 pulls we had good air fuel and 521 whp. I like ebl and want to get it for my turbo 305 next spring

Other than the cost it is hard to beat Holley. If you want to do Megasquirt, plan on a steep learning curve.

seiplentz

iTrader: (2)

megasquirt is not even an option. I know its very capable my brother has it and its been a nightmare to tune. You need to dedicate serious time to it. Its not much fun when you cant get it right.

I think I am going to call holley tomorrow and ask a lot of questions about options.

AEM tells you don't use it unless your a professional tuner or you could blow your engine up.Big Stuff 3 is an option.EZI EFI was made by them and COMP Cams bought the system from BIG Stuff and renamed it .

efiguy

iTrader: (2)

If you're going to actually drive the car then the BS3 is the last system you want, it's geared almost solely for drag racing. Not a great driving system.
AEM says that as a disclaimer and to support their dealers. It's an awesome system.
Comp cams didn't buy EZ from BS, not even close. The FAST stuff was originally Fel Pro. I believe you're thinking of MSD. Their Blaster EFI was a dumbed down BS3.

Thanks.

So I spoke to holley about the HP system for about 30 min yesterday. They were more then helpful answering all my questions. We went over all the options and made a list parts I would need for a complete setup. So far this is number 1.

seiplentz

iTrader: (2)

I am slightly interested in the AEM but the harness prices and options are a little steep. I am also unsure if there is any kind of self learn features at all or if it really needs to be pro tuned to get the most out of it.

Here is list I built for options.

PN: 30-7108 - Infinity-8h Stand-Alone Programmable Engine Management System - $1433.89
PN: 30-3809 - Infinity-8h Universal Core Wiring Harness - $666.49

My experience, forget about self tuning. Self tuning only gets into a ball park. For the systems that offer self tuning and manual tuning, it;s a good way to get you close, but then fine tuning needs to be done manually. Also self tuning only takes care of fuel, not ignition tuning, so there's a whole 'nother aspect that needs to be addressed.

efiguy

iTrader: (2)

Email me directly at fastone01@hotmail.com I can help with that.
And take six shooters advice, ask any accomplished tuner and they'll tell you self learning has limited benefits. But also ANY system will benefit from a professional tune. I can help with that too.

Yes very much so. Been an Accel dealer for over 12 years and have now converted my own car from Accel to AEM.
It throws a lot of info at you but it's great. Amazing to see the difference in tech from the Accel to the Infinity. Accel was ahead of it's time back in the early 2000's so it had some legs, but this Infinity is way more capable than the Gen 7 or even the new Holley HP, and at a pretty competitive price.

Thanks.

I agree it will still need to be manually tuned. But at least you are close to dial it all in and a pro tuner wont have to spend as much time with it.

efiguy

iTrader: (2)

But the self learning still only does fuel and a good tuner will spend less than an hour calibrating the fuel curve.
Just an fyi, some of the new systems are so fast anymore that you can enter just a few different numbers vertically in the VE table and the O2 feedback will correct, and they actually run pretty well.
Besides, spark timing and entering the correct air/fuel is just as important as the VE, in some cases more so. And those tables aren't part of the self tuning process anyway, nor is transient fueling.
Here's what a good tuner can do from home, I'm supremeefi.

I think too much is being put into the tuning aspect. Twenty years ago, sure, when all people knew how to do was max out the PE tables and tune with fuel pressure, absolutely, a good tuner was imperative for an enjoyable ride, especially with boost. But the information out there today, as well as what we know, I think too much is being put into a credible tuner. Spark maps can be cut and pasted into an XDF from any bin, observed, then modified as you go. VE is learned as well as commanded, and if O2 correction is having a problem keeping up, then transient can be added. I mean unless we're talking Ion Sense Tuning, I wouldn't pay two grand for any system. JMO...

Find out what happens when you have an ignition problem and blowing spark out at wot or running to rich to begin with at wot and have self learn see the incomplete burn as lean and start adding more fuel to make problem even worse lol. Self tune self learn only gets so far as others stated. Rest you have to manually tune. And in general its not terribly difficult getting ve tables for driving good. The hard parts seem to be starting hot and cold and sometimes idle parameters. There you spend most time it seems atleast in my experience

Did you get the Holley? The mustang shop I frequent with my other car sells alot of the holley stuff. Plus there is also Pro-M. They make a stand alone system now. If your happy with the commander the holley hp is a step up from that.

IROCZ1989

iTrader: (1)

Forget that high price. For right around 1500-1600 you get a complete Holley Hp with everything needed to install. I bought mine here:

http://mooreracecraft.com/holleyhp_efi.html

I know a few that use the fast classic, some that use the fast 2.0 and alot that use the holley hp. Never ran across a car with a AEM. Best thing about holley hp is there tech line is open on sat as well. Plus Moore racecraft is always a phone call away. Its the number one selling aftermarket efi for a reason. Plus you have their holley hp forum as well.

kurtis72

I have used the Holley HP, tuned the factory EEPROMs and MegaSquirt. They are all options for 3rd gen MPI. My opinions:

Factory Tuning: Tedious to swap EEPROM each time you modify something. But it is the cheapest solution and you retain VSS and emissions function. Tech support here on forums is good.

Holley: Most expensive, but easiest to get up and running. VSS will work but not emissions. GREAT tech support from Holley. They have a 7" display for $500-600 that I have not tested.

MegaSquirt: Medium price, but time consuming to get set up right. No VSS, no emissions. Very expandable. Works with $40 android tablet for gauges and tuning. OK tech support from diyautotune.com


I am working on a hybrid MS-Factory ECU setup where the MS runs the fuel, spark, idle valve and the GM ECU runs VSS and emissions. I will write up a how-to when I get it working.

Currently it's all the above. I like Holley, Orr does as well. Others will tell you megasquirt or ebl.Efiguy likes what ever he is a dealer for at the moment, or what cuts it in 2019, apparently only AEM. Alot to choose from. I know you want to keep your factory crossfire. There are sites dedicated to that intake system. And maybe some here can help you with that as well.

I’ve had enough of your crap. You've basically called me everything but a human being relentlessly. However I refrained from doing the same. I think that speaks volumes of the type of person we both are.
Here are the facts, I’ve sold one system off this forum. I’ve given countless people FREE help on their Accel and other systems(as noted I’m a FAST and Holley dealer as well). Plus I have a video on YouTube that shows, in detail, how to wire, setup and tune all Accel systems. It’s FREE by the way.
So get a life and go bother someone who truly helps no one, such as yourself.
Thank you.

I never insulted you personally, so don't get all worked up. I only pick on your methods. Your your own best champion of the good you do. But, a big but in that. You are a dealer. A non paying vendor I might add. You sell on here, or try to sell on here. Dont get your panties in a bunch on a public forum. If you have a personal issue with me pm me. Dont have to air your dirty laundry on the board letting everyone know how much you loathe me. Sorry I find humor in the fact you tell someone that it isnt going to cut it in 2019. I find that funny. So what? Like I said your free to pm me or if you want my email that too. Would you like my number so you can verbally abuse me? Crack a cold one. Sounds like your on edge for some reason.

Your having a hard time arnt you? I never said anything you just wrote. I dont care if your the best tuner in the world. I never claimed to be anything. You did, numerous times when you name dropped all kinds of people who trained you. You did this and that and your so helpful all for FREEE!!! Here is my problem with you. So try to follow the bouncing ball. You dont pay advertising fees here. Ok do you understand that statement? Ok. Your a dealer, you have said so numerous times. Ok so we got you not paying to advertise here and am a dealer. Next you sell the exact same systems that paying vendors sell. Ok are we still on the same page? Do you get it yet? You sell or try to sell behind the scenes contacting people with issues to sell a product as a dealer. So explain to me why you should be able to sell here for free while a paying vendor does not? Answer correctly and you win the prize of me leaving you alone.

You’ll never leave me alone or apologize, you said it yourself in another thread. So how would anything change?
