1988 Cavalier 2.0L 4 cyl.

Post by dsleepy47 »

Stock vehicle. ECU died so I put together a MS1 v2.2 I have had sitting around. The vehicle has TBI with 1 56 lb/hr injector and GM DIS. I am using fidle to control a PWM IAC from a 1994 Explorer that I attached to the inlet plenum and made an adapter that I put in place of the stepper valve. I am using output 1 to control the coolant fan relay and output 2 to control the torque converter lockup solenoid based on MAP with inverted output. The solenoid circuit has a 3rd gear switch so the solenoid energizes only when the transmission is in 3rd gear and MAP is below the setpoint. I am still fine tuning but everything is working so far.
