Hi, I just installed 0.4.4 in to mx5 vvt. ECU acts very unstable. For example if idle valve is set to work before start, fuel pump and some LED's activates randomly and if in this state I plug usb in to pc fuel pump starts pumping without stop and idle valve starts to sound much louder. If I disable idle before start, It all seams stable, but if I try to start engine, injector and spark output goes ~double speed and rps's is not stable. If I try to start engine without pc pluged in, engine starts more or less fine (on base tune). Also, sometimes fuel pump relay after priming flickers few times before switches off.
Feels like ecu picks all noise it can get, but why? any similar experience?
Not a expert in electronics, but it is not my first ecu install.
