Heating up after pcm install.

Ive had a problem with a dyno tune recently but was too far away from the shop to get it fixed.They sent me a new pcm which was supposed to be programmed correctly.I had a shifting problem,which was taken care of,but my temps now get alot higher than before.I dont ever hear the first fan kick on!! Im about to hook it up to hp tuner to change them so if anyone has the fan settings for a 170 stat i would appreciate the help.

Didi you have your fans changed in the first tune, I bet they forgot them in the second tune. Regards, Jeff

I can almost bet that the new PCM has OEM fan settings.

you can set your 1st fan to kick on at 190 and to turn off at 185, the 2nd fan to come on at 197 and turn off 193. This is just to give you an idea of how they should come on and turn off. Make adjustments to suit your needs and geographical area.

My best advise is to get a laptop and HPTuners and D.I.Y. Regards, Jeff
