Does the 1MB LS1B Pcms use throttle pedal position or Throttle body position for part throttle shifting?
I been slowly adjusting my Tow/Haul tuning on a 2500HD and just dawned on me that maybe its not doing what i want when i want it to because i have been watching the wrong PID.
Does anybody know what it is using for part throttle shifting?
I'm fairly sure it uses TP at the TB (anyone please correct me).
99% sure your correct.. cause when you have the cruise set, the APP reads 0 and the TB TPS reads the %. So no way the APP has anything to do with it or cruise would act weird?
APP is "requested" throttle;
TP is "delivered" throttle (actual throttle);
you can see why CC would use TP.
