i have a 88 tbi camaro with a 355 and we moved some how the ecm got lost i had it out to get a new chip made so i ordered a used one but did not know the service number of my old one so they sent me a 01227730 now it does not spray fuel? if i pour gas in the throtle body it fires but no gas comes out of the injectors any ideas? p.s. i have fuel presure

 

The computer you got was a TPI computer. Your part number is 1228063 for TBI motor. Get that computer changed and go from there.

 

that sucks! i ordered it from hawks and told them i was for a 88 tbi they said that is what this was from but without my service number they couldnt garentee it would work

 

https://www.thirdgen.org/promintro at the very bottom of the page is the list of ECM's and all pertinent information to them. They might take an exchange. I've seen a lot of people just see the TXI and assume the X is P or B. It's happened but these are two ENTIRELY different fuel injections. Hope you get your ECM exchanged.

I knew I was wrong so I double checked... This is your ECM number 1228063. Uses basically the same components except the ECM is different obviously, and the Mask ID or Calibration ID is different.

 

i got a 1228746 ecm and the car starts right up but dies? on the plus side my injectors are workin now

 

Your current Prom, (ECM Chip) probably isn't capable of fueling the 355. The fuel pressure should be high enough to flow enough fuel for the higher horsepower motor than the stock. https://www.thirdgen.org/forums/tbi/...free-tune.html This thread will help immensely. I'm not sure that is the right ECM though. I've edited my previous posts to show 1228063 as the part number. I'm not sure on the differences or even if a 1228746 computer will interchange with no problem.

 

the ecm that i got is for a 89 tbi i think they had vats could this be the problem if so how can i get rid of it?

 

Everything I've read here has contradicted what I've experienced with vats. When vats thinks someone is stealing the car, it won't even crank. Other people say the injectors won't fire. If it's vats your car wouldn't even crank over. I'm at a loss as to what the problem could be.

 

tunercat says 1988 is a 1228063($4D Mask) 1989-1992 is 8746 ($61 Mask).

what chip is in it? car should run with a 305 chip but not very well.
