I'm a little confused here. I want my MS to control Fuel and Spark, but want the OEM ECU to control idle and the A/C. Do i need to get that PWM IAC mod kit? So far I've been following what Braineack put up for the DIY MS article. Got everything soldered up to look exactly like his.

I have a feeling that the PWM IAC mod kit is only for full MS standalone. Am I right?

 

You dont need it if you want your stock ECU to control idle.

 

Ok, thats what i thought. Just needed someone to confirm. Thanks!!
