Jason can you give me any advice or tips on changing from speed density to OBD 1. What year computer did you use and why? Was the change worth the effort. Thanks

Sorry for the delayed reply...was out of town for the holidays.

The swap is worth it now that I look back, although at the time it was a pain (mostly due to the fact that I didnt have the GM wiring schematics).

I used:

95 PCM
95 engine wiring harness
heated O2's
95 MAF
95+ Opti and related stuff (harness)

There were about 5 wires that were different between the harnesses (i cut and spliced at the firewall). They were the biggest problem for me since I didnt have the wiring schematics for a while. Stuff like AC (which I took out), skip shift (which 93 dont have obviously), and a couple other difference between the years.

If you have the schematics, it wont be that bad. Well worth it now that I can use LT1 Edit.

Let me know if you have any other questions
Jason

 

Do you have the schematis for the wiring for the wiring diagrams. Thanks, Clyde

 

No I dont....you would have to buy/borrow the manuals. I got them from a friend.

the libraries around here carry the GM factory manuals that have all the wiring diagrams, i would assume yours should too

 

Thanks Chevy Guy....
