Re: PCMFORLESS ??
I have a question about the 96 fan temps.
the 96's have a low - high speed fan setup where both fans run either at low speed or high speed.
low speed 219on - 207off
high speed 228on - 214off
I changed thermostats to 160, so I need to adjust the fan temps accordingly.
what would you recommmend?
I was thinking about lowering each number by 20 degrees. this way the temp spreads are keep the same .... but a little :confused:
the car is otherwise stock, but I do road race it, and I want the temps cooler in the pits.

good reason not to buy a hypertech!

Re: PCMFORLESS ?? (larryfs)
If you look at PCMFORLESS's web page, one service they offer is OBDII to OBDI conversion, makes your OBDII '96 such that it can be programmed via an OBDI tuning application like Tunercat. Then, you have ultimate flexibility to go in and set your fans to whatever temp you want, add a degree or few of spark advance anywhere in the rpm band, alter Power Enrichment fuel tables, etc. If you have access to a shop with a dyno and that has a wide band oxygen sensor you could get your air/fuel curve well optimized if you spent some time and pulls... took your laptop and cable to the dyno shop with you.
Also, I believe that once you do the OBDII-to-OBDI conversion, if you have your own cable and laptop you can then get PCMFORLESS's tuning for $50 a pop emailed to you to upload with your cable and laptop yourself.
If I had a '96, I would definitely consider the conversion to OBDI... just to get the car setup to where I could make changes to the programming myself. But that's me. I think the only major change with the conversion to OBDI is that the PCM ignores input from the crank position sensor, which is an OBDII-specific sensor not installed on OBDI cars. There's a FAQ about it on their site.

Re: PCMFORLESS ?? (larryfs)
does that hypertech keep the 2 speed fan setup, or just does 1 speed at those temps?
