Default MAC PWM valve control w/ Automatic P75 ECU

Hey all,

I know very few of you will even know what i'm talking about, but I have an Automatic P75 ecu converted to manual and chipped. I was told this ECU already had the components needed to control boost via PWM on eCtune.. can anyone verify this for me?? does it use EGR or iAB ? thanks in advance

Look up the PWM EGR instructions on the eCtune forum or help file to identify if your ecu has the components.

read this (All ecus have the circuitry but not components, for the PWM (pulse width modulated) output)

I'm pretty sure you use the trans lockup solenoid output on that ECU (12v+). No need to add any other parts.
