Tpi Trouble

I hav an 350 with 92 tpi.
I have done much with this motor, and it would not run great.
Someone who can read the log for me an tell me what to do?
I live in Norway, bad english, but I hope you understand..
It have the com xtream 282 cam, ported, bigger valves, 12-1 comp an so on.
Hope someone can help, In norway no one can...

I cant upload the file here, but give me an E mail adress and I will send it to you.

The Engine starts easy, good idle, and very good throttle response.
But when i am driving I have very good power in 1. gear, and up with full throttle. If I am driving in 3. and want to accelrate, push the throttle slow, it just wont give me power, fells like it dies..

Re: Tpi Trouble

You need to have a chip programmed for the modifications done to your car. The 92 tpi used a speed density fuel management system and doesn't take well to severe engine mods. Ie cams, heads, and so on. Check online for companies that tune engine computers tell them what you have and they will make a custom chip for your car. That should fix your problems. If you need more info my email is chevroletcamaroirocz@yahoo.com.

Re: Tpi Trouble

Hello.
I have a new chip, it it made by this guy :www.creativefuelinjection.se

He have made3 different, and he have improved them each time. But the engine doesnt run great.
He says it it a adjustment to timing, or fuel pressure.
I run with 48 psi, and have tryed many different timings.. 0-8 degres--
I have a log, if you ore someone else can look at it for me, i will email it!

Re: Tpi Trouble

hopefully that isnt necessary!

You should also ask your question over at the DUY prom board. Some of those guys know a lot more about the little subtleties of chip programming.
