I am not running on any ECU although i have 2 piggybacks with me, Emanage Blue original Japan and Unichip Q without Turbo Module. I am not installing them as my current mods doesn't require an aftermarket ECU to run. If i ever needed one, i will go with something closer to stand alone.Could this be related to a bad crank angle sensor?
Are you running any custom sensors? can the EManage be bypassed?
