Sorry to buck, I knew of a Caddy that had such a set up of two on one bank and two on the other.
I did not see the wiring diagram before...interesting and informing.
So was what I read about the PCM in my 93 being a one year PCM correct?? If so is there a direct replacement that is better?
And can you commit on my ideas:
A few concerns in my case is all the major rewiring in my van, and as I understand things at this point, the OBDII Systems are very hard to get into to do tuning were the OBDI systems are basically wide open.
Also it seems much easily to enable the lean cruse system.
Lastly I want to tune for MPG and think a PCM with so called learning systems could fight and remove improvements in MPG to suit its core programing, where I think a OBDI system might be less able to reprogram fuel settings.
Also my Chip was already programed for a V8 350, in my van with its current drive train...once I make to changes to it and the PCM to run the TPI I believe it is all set to run my new engine.
Also where is the Lean Cruse function? In the Eprong or in the Main PCM?? I had a tuner years ago say he programed a Lean Cruse into my eprong, even sent a tail pipe sniffer to refine it.
Was that on the level?? It did not seem to make any changes and MPG did not change.
Your opinions?
Thanks for helping me with this.
