I am looking for someone to help me tune my TPI. The cars got a nasty lean condition, always has. Shes pretty stock, but I wanna feel a little more out of what I've got before I get crazy with it. It pings at WOT in the upper rpms. I changed the fuel pump a while back and it almost completely cured this, but its still doing it and I don't feel I'm getting all I could out her. I am forced to hardly ever push it. Anyway, if you know someone who tunes TPI and could help me, I'd appreciate it

I am also waiting on the answer to this question too. If you get any leads, let me know. I was able to locate a place in South San Fran that burns custom PROM's based on the set up your car has and they seemed pretty reasonable in price as well!

If you are interested:

SuperChip retailer:

Gotelli Auto Supply
321 El Camino
650 522-8811

 

Lol, yes I am very familiar with Gotellis. I go there at least once a month to just check things out.
But if you don't mind my asking... what exactly is reasonable? From my experience nothing there is really reasonable. They seem to a little pricey on damn near everything. The only upside is they tend to not charge tax on alot of things. But anyway, I would love to get a cutsom prom burned. But I might just save my money and swap over to speed density so I can tune the car myself with a laptop.

hey norcal!!! i live in hayward. not to far from you. have to changed your fuel filter??? let me know if you want any help??

 

Yeah, fuel filter was changed not long ago, as well as the gas tank, and the fuel pump. It cured alot of the ping I was experiencing, but its still not totally gone. Right now it seems to not be doing it at all. But I also have an exhaust leak from the AIR setup on the pass side manifold, so that might be throwing things off, and not letting me hear the ping if it is even there anymore. I was planning on doing maybe headers and injectors next spring when I get some mroe money and can tear the top end apart. MIght as well replace it all in one swoop. Anyways, hope to see you around sometime bro!

Will

 

have you had your injectors checked?

 

When I asked for a quote on the chip for my car it was under 200 bucks. I call that reasonable especially when they are asking what I want on the chip and what mods I have on my car. I was hoping for a more personal touch with some datalogging done in advance but this seems too much to ask.

Hey Will (or any of you Silicon valley types... let's get together and figure this dang tuning thing out. We're smart enough and definitely have the computer hardware to do it.

What do you say? I can spare a Saturday or two a month to hang out and do this.

 

Hey bro, I strongly invite you to check out SBFA. We are the southbay f-body association. We meet once a month to hang out, and have events throughout the year such as bbq's, track days, and so on. We are all headed to the track on the 23rd of this month. But yes I would definitely like to gtg and maybe get some tuning info, once my cars all registered and what not. If you want more info about us, just check out www.southbayfbody.com and follow the links to our message board!

Will

 

I'm there... Lord knows the West Coast Pontiac group is totally letting me down.

Thanks and see you there.

 

Once I get this new engine together I am going to need some tuning... I am thinking of finding someone to burn me a chip for the new engine, just a ballpark chip which will be set for injector constants and stuff... I know you can't burn one chip and have it perfect, but yeah.

After that, I plan on buying the stuff and diving into it the best I can, does anyone have equipment in the area? I take it as no one in the area is a pro on tuning, but does anyone have an idea about it?

It's rough, I see all these intelligent people that have so much knowledge about tuning, but I ask a simple question and get bombed with "GO SEARCH" or "READ, IT's ALL HERE"... I don't consider that help, if it's so easy to find, why can't I find the info, and why can't you just tell me.

But I agree, we need to figure this stuff out, and I have a feeling it might take a few minds coming together. I know a bit about computers, but not much about raw programming. I have figured out data logging, but what good is that without tuning ability?

 

hey norcalz28 how many SBFA members are going to the track on the 23rd I was thinking of going maybe I can talk some of the sac crew into going

 

I hear ya, brother. I got a laptop we can use if we can figure out what equipment to buy in order to interface the computer and then we'll need the PROM burning equipment. I've heard you can get this all for roughly 300 bucks or so.

I'm still a little leary attempting all this without an experienced guide but unless I'm way off base all we have to do is simply replace the original PROM and we're good.

Thoughts on how we can get rolling on this? Hell, if this works out I bet we can make some money on the side burining custom chips for fellow F's. I guess a visit (search) to the PROM board is in order...

 

hey guys, just thought id chime in here. While I am by no means what I would consider a pro -- I am far from newbie -- I do have experience tuning my setup.

basic setup is
350 SBC .30 over, Edelbrock Performer aluminum heads, Comp Hyd. Roller Cam 218/224 112 LSA, Speed Pro Hyperutectic pistons, 10:1 CR, Edelbrock Performer intake, 2bbl TBI 1-13/16" bores w/BBC injectors @16psi, coated Edelbrock headers, 3" exhaust.

It took me about 6mos. from start to tune idle and cruise (haven't even played with WOT)-- but needless to say I've know my way around the '746 ecm and I have a good working knowledge of most tuning apps.

 

Do you have the computer equipment/PROM burner and so forth?

Hell, I'd pay to learn what you know.

 

I never thought I'd end up tuning other peoples cars, so I opted for the single car solution and went with the PROMinator. Therefore, I never needed a PROM Burner / Eraser or chips. Edit, download and go. I liked the simplicity of it all.

I do have an ample supply of laptops / workstations and licensed versions of TunerPro RT and TunerCat RT, WinALDL, data cables and some good data anlaysis tools.

 

Just curious... how much was the PROMinator?

I am interested in learning anything I can about tuning... IIRC you have TBI, so I guess it would be a bit different for me with TPI, but maybe I could still get some knowledge that would carry over into my area.

Let me know if any of you guys are gonna get together to learn or experiment.

 

last time i checked the PROMinator standard was $175.00 and the Pro version is $275.00
The Pro version affords the convenience of switching bins on the fly without the ecm going into limp mode. You can still buy a switcher with the standard version, however, for the few seconds during the period when the new bin is downloaded the ecm will have a fit and go into limp mode.

www.prominator.com
check his site for the latest.

 

Hmmm... saw this:

NOTE: PROMinator is NOT approved for use on emissions-controlled vehicles, therefore it is ONLY legal for off-road use!

Then again, it can store 8 images (Pro version) so maybe you can flip a dip switch and then be back to default/original. Any ideas on that Adam?

 

yeah, but first its alex, not adam
to change bins there is a remote rotary switch, alot more convenient than flipping dip switches

As far as the disclaimer, it's not a matter of whether it passes emissions tests or not...it's simply a violation of FEDERAL (not just state!) regulations to modify emissions-controlled equipment, unless the device being installed has a CARB certificate.

You could also find a spare ecm on ebay.

 

Argh.

Thanks Alex.

Mike

 

a suggestion would be to call dynolabs in San Ramon. They have a chassis dyno and can burn you a custom chip. They can see what your system is doing and correct it. They dialed in my buddy's mustang(I know...) but when I get my motor done in my 89 RS Im gonna have them do me up a nice chip.

 

Well... that's worthy information:

Dynolabs, San Ramon

100-125 bucks for testing.
