I did a search for this and was unable to get what I was looking forWhat is PWM and where is it in HP Tuners?I cannot seem to find it...Thanks!

 

pulse width modulation, under the system general tab.

 

[QUOTE=foff667]pulse width modulation, under the system general tab.[/QUOTE

Its under vats control correct?Should I turn it to none? I have a vacuum modulated trans.....Thanks

 

VATS PWM is not the same PWM that controls yout converter lock up. You can not turn lockup PWM off with HP Tuners. It is something that is converted from PWM to on/off with a modification to the transmission. If you have a built transmission that is vacuum modulated, there is a good chance your transmission builder already converted the lockup PWM to on/off. Check with yout tranny builder.

 

Glad i didnt change that than,He did put a chip in it.But when I change the TCC DC from 96-10 to 100-90 what an incredible lock up difference....
