Current E-67 GMPP PWM programming?
Does anyone know if the current E-67 ECM's from GMPP contain the pwm programming? As it comes out of the box, its set up for one fan on/off at 207 degree on a 30 amp fuse/relay. I would like to run one or two pans thru PWM if its not a lot of work. Aftermarket controllers are my second choice but using the OEM control and existing engine water sensor would be best.

I read a lot of those forums before asking here. You find some say yes, some say no and no one that is sure because I think it was in the ECM for a while but now is not. I think I will just go with a aftermarket version and I know it will work.
