There has been extensive effort put towards finding the little gremlin, which has caused poor or non running status of the ol'TBI 305. For those who may be interested in the past efforts and different things that were first ruled out, see the old post. https://www.thirdgen.org/forums/elec...ector-has.html

We used a spare computer out of an 91 V6 5spd truck and the car started right up. This surprised me as I thought it had to have a 305 computer. We pulled the chip out of my computer and put it in the truck computer and it still ran fine. Now my question is, what is not going to function properly with the V6 truck computer instead of mine. I know the electric fan is not kicking on. Is this because of the truck computer or does the chip control all of this?

 

Bump. Anyone have any input?

 

whats the number of the ECMs and whats the brodcast code of the chips?

 

*89 Camaro 305 auto computer:
ECU-> 1228746
Chip->top: ANTT
bottom: JT8 (G) / J6/ P
LFIVM163
AF42


*91 Chevy V6/5spd pickup computer:
ECU-> 16144288
Chip->top: AWDR
bottom: JT8 (G) / J6/ P
LFIOD252 {note, the "O" had a line through it}
ADO8 {same as above}


Thanks a million.

 

I see now that there is a ECM sub forum, sorry for the newbie mistake.
