2001 Astro van V8 tuning

Postby sfeaver » Sat Jan 11, 2020 7:52 am

I have a 2001 Astro that I have just put a 350 into. It came out of my 1997 that has rusted out. It has the 2002 Express van tune on it.

I am looking for some help on how to make the PRNDL display work correctly. On the 97 it was hard wired, but on the 2001 it goes over serial data. Also, the overhead console never updated properly either, so I know there is some programming differences between the two years. I have updated the wiring harness on the engine to the 2001 model year. With a stock tune on the PCM these things work correctly, but of course engine won't run correctly on a six cylinder tune.

So basically, looking for some help on how to make the PRNDL and overhead console work correctly with a 350 cu. in V8 engine. Or how to make the stock tune work with the V8 engine. I have EFILive, and have also just downloaded PCMHammer and have tinkered with it a little. Enough to pull the stock tune out of the PCM.

Thanks in advance for any assistance!
