Car idles erratically, RPM is moving from 1300 to 1700 back and forth. Modifying the Idle% vs Target RPM table has no effect. Tried all zero and idle feedback still goes to minimum value trying to lower the RPMs.

I got the 1313 unit on an 03 evo. Using the base MAP calibration. I've adjusted the TPS sensor, checked all others - AIT, MAP, Coolant, 02.

TPS is below 'Idle off' threshold, RPS are within limits of idle. Tried the options to Reset Idle motor at kef off and on. No luck...

I need some help here. Thanks in advance

 

Did you check this....



If you are having Idle control issues on Mitsubishi, check and MAKE SURE that you have the following options set to ON

Idle 1/2 Stepper
Idle 3/4 Stepper

These options can be found under the Options full list menu.

I am seeing several calibrations with these turned off, the idle circuit will not work with these options turned off.

 

I checked the options and they are ON. Thanks for the advice.

Should I try to go back to the stock ECU to make sure its not a bad stepper motor? It did work just a few days ago though...

 

email me your cali i can check it.
