its all wired up and idles pretty good now - nothing seems out of the ordinary - the chip was modified to use the stock injectors.  

Been talking to a guy on 60degree that has similar setup running GTP injectors so I've picked up a set and amd going to get the BIN file from him.

the last thing i want is to lean out up top

haven't been over here in a while but figured i'd update a little..  the T04E turbo is going in this week with a large intercooler.  

Any of your guys familiar with www.MOATES.net?  or used the AUTOprom or ostrich in your tgp's?

I'm about ready to just get an SAFC to do the last fine tuning of the fuel tables

why would they need to road test anything if all you are doing is dropping the automatic?  most of his chips don't need any adjustment -

only reason mine isn't perfect is that mine is the TGP ecm running a 3.4dohc which he hasn't had to tune before -

doesn't hurt to toss em an email and see what they say

I'm not real familiar with the mastach - but the pinouts on the diagnostic port do vary between gm cars - I noticed this when I got my scantool

may be a place to start looking

if you think that 35$ is expensive then sure

he's the one tuning my 3.4dohc runnign on TGP ecm

www.gmtuners.com does custom chips

DarthFiero from pennocks fiero forum - he also has a website.. http://www.gmtuners.com/  --- right now I'm just trying to get it runnign real well NA before I start adding in boost - the TGP's factory wastegate solenoid control settings are perfect for a stock 3.4dohc with an intercooler and should put it at almost 300 whp with some tuning.


may as well post an update since I started this thread -

I pulled the TPS and MAP plugs to test them with a multi meter and now the MAP sensor is reading 2.31 v with the engine off and key on and its throwing a code 34 (low map voltage)  so I have a feeling that my brand new map sensor may be part of the problem with it running so rich and randomly stalling -
But i finally ran the engine long enough today to get it into closed loop and it sounded good - the knock sensor didn't go crazy like the first couple times i fired it up so it must be learning a bit.  its getting better - hopefully it'll be flawless NA for me to take it up to the big Carlisle show in a couple weeks -
Then I can start designing the grand national based turbo setup, which once the electronics are worked out is the easy part, i can weld just fine, tuning is new to me

Hey guys -I haven't posted much but figured this place would be a great resource for me -- I currently have a 95 grand prix 3.4 dohc engine swapped into my 86 Fiero runnign on a 90 TGPecm .. the auto tranny has been disabled for using the manual trans in my car..  and I had someone burn a chip that was tweaked to help it run the 3.4..  

currently it will barely idle and is running pig rich..  I hooked up my actron scantool and wrote down a few of the recorded data logs.

not sure exactly what info to gather to help diagnose the running WAY rich

any advice you can offer would be great.
