PWM questions

[kyphur]

On the VCM controls there's a PWM on/off switch. I'm reading on LS1 tech about PWM delete but I'm not really finding anything that directly addresses the PWM in the tuning software. I see references to it in the TCC duty cycle min/max and under ENGINE>ENGINE>DELIVERED TORQUE.

What exactly does PWM do and where is it addressed in the tuner?

From the factory the PCM pulses the pressure solenoid for the torque converter lockup to maintain slip and engage smoothly. To disable it you simply set the entire max table to 100% and the entire min table to 99%. This will make the torque converter act like an on/off switch which is disabling the PWM.

Are you talking about the TCC Duty Cycle minimum and maxmium tables?

Yes
