[QUOTE="F-127, post: 124982, member: 966"] There is in fact a function in programming that handles glow plug duty cycle in regards to battery voltage. From 0-14.01 volts, duty cycle is 99%, this then drops 0% duty cycle at 14.91V and higher. I can only speak for TDE1 though, I don't know if that is the same values for other PCMs. It can be changed in tuning, but if it was programmed that way, there is probably a reason. As you've heard, it was likely to prevent GP burnout. [/QUOTE]
