Hello! New here, looked around a little and read the manual but that what spured this question. I have a 2001 Jeep (WJ) Grand Cherokee with a I6 4.0 coil over spark plug ingnition and EFI (muli-port) system. It also has a stepper IAC. Which system will work, if it can work, with my Jeep?

From what I read, I maybe able to use MS1 and just control the fuel but MS1 cannot control a stepper IAC. So, What to do?

Anyone here have a system setup and working for any '99 and up Jeep?

Thanks,

J. Kelley

MS 2 has stepper motor control built in. As for coil over plug you could go wasted spark.
