I didn't want to hijack the thread for the MSPNP 96-97 thread, but I wanted to know if the guys at DIY had determined the proper values for the stock coolant/IAT sensors to be entered into easytherm. I've tried it myself, but it seems I can never get it quite right (I should probably just go ahead and buy a GM coolant sensor) but didn't know if you had gotten to the development point where you had this already figured out. Thanks!

 

Have you tried the RX7 values that are defaulted in the easytherm menu?

 

Yes, I tried the RX-7 values, but from what I can tell, it reads approximately 20* cooler on Megatune than what it should be(my stock computer still controls the fans and they kick on at about 175* according to Megatune). I just figured since DIY was making progress with their PNP system, they may have determined the correct values (I wasn't sure if they would be the same as the 94-95 values, then again, those haven't been posted either).

 

Hmm. You can try my values, though i had to calculate my own bias resistance values for the '99. You did remove R7 right?
1544 bias Celsius temps
0 6000
40 1100
80 320

 

Thanks for the info, I'll give it a try later today. And yes, I did leave out R7 on my MS. Hopefully someone from DIY will also chime in here sometime too.

 

There are also some values in the sticked thread titled "software installation".

 

Then you need to remove R7.
