HI, I'm running a evo IV swap in my mitsubishi Outlander, with ECU swap from a evo VII so I can reflash and tune.

Everything is up an running, I'm just beginning the tuning process, calibrating injectors etc

But my check engine light is always on, no DTC, switch back to the IV ecu and the check engine works and turns off after a second. Install the VII ecu and check engine always on with no codes

Is there a diagnostic wire that should be move to another place, or does anybody has an idea why the check engine doesn't turn off.

Something I can disable in ecuflash?

Thanks for your help
