Does anyone know how to do this for a 96 3.8 firebird?
Does anyone know how to do this for a 96 3.8 firebird?
direct plug and play swap. No biggy, did it in a couple 96 cars already
thanks.
Is it really?
I honestly know little about Firebird PCMs, but on the GPs there is a major generational revision from 97 to 98 where merely replacing the PCM is not possible without a LOT of work to accomodate the rest of the wiring harness.
When did the Gen III PCMs get placed in the Firebirds? Was it in 98 like the GPs?

13.82 @ 105.28 on 87 octane! (2.42 60-foot).

All this and 39MPG to boot. What more can a man ask for?

If I recall back to my F-body days, the 96 Fbody V6 PCMs were the old 256k PCMs. The 97 and up have the 512k.
The 96 Lumina/Beretta's ETC also are OBD II but have the 256k bin.

In effect they got the gen II PCMs the same time as the GPs, then.
If thats the case, it would logically take a lot more than a simple PCM swap. Going from OBD-I to OBD-II requires more than a different PCM. Likely the complete harness would need to be added/changed. The 256k ones were OBD-I, I believe. First year cars with 512k were the OBD-II PCMs and equivalent to the 97 GP and Bonnies... the next gen PCMs were from 98 to 03 and quite different from the 97s (traditionally they needed a complete harness swap to go from the 97 to the more desireable 98-03 PCM). From 04 on they had the 1024k bins and thats a completely other story.

Nope, in the f-bodies its a simple swap. In 1995 (California) and all 1996's They're OBD II using 256k PCM's.

Ack! OBD-II and 256k bins? GM is wierd at times. Thankfully I do not think that this even existed in the GP world. OBD-II started in 97 and was 512k from day 1.
