I wrote Zoomer the following last night:

Zoomer,
I wrote you earlier about having my PCM flashed to the 2000 PCM code and you told me you could do that. I was scanning your website and you wrote:
"For some people running the engine too cold will set an SES light. To get around this you can put a 16-20 k ohm resistor in place of the air intake temp sensor... "
http://www.zzperformance.com/zzp/inf...liminatekr.htm
Now, do you think this would cure the 2001/2002 160°F stat PCM incompatibility issue? Currently running a 160 stat in an 01/02 Fbody V6 will cause the following problems:
- SES light stating coolant temp sensor voltage is too high (too cold water temp)
- Kill the water temp gauge
- Turn the coolant fans on high and run them continuously until the PCM is reset
I wouldn't mind it so much if it didn't kill the gauge and run the fans on high continuously. I have attempted in the past to mess with the coolant sensor by attaching a resistor in parallel with the circuit and fool the PCM - but this did not work as far as I know. I was hoping my hypertech power tuner would fix my PCM and allow me to run the 160 stat, but it doesn't, and hypertech is aware of this issue but won't do anything about it.
Do you think this would work - or should I still let you reprogram my PCM? I know the reprogramming will work if it is 2000 code [img]smile.gif[/img] .
Thanks again,
Dominic

Has anyone else tried this? Im going to attempt it soon - what the hell right? :D
This kind of makes sense since 16-20Kohm makes the PCM think the incoming air is 0-15degrees F! If its that cold its possible the coolant will be 165-170 or so as well right? :D
