Hello,

Experiencing something realy odd here.

Mazda mx5 turbo megasquirt 2 ecu

Above 70kpa doesnt matter what rpm the injector pulse width is fixed and no longer response to the cell in the VE map.

I can make all the cells above 70kpa 0 or 255 and no response in fueling/injector pw /lambda valeu.

Below 70kpa i can tune the cells no problem.

Cant find a setting which could cause this.

Map limit is off, accel enrich is off tryd playing around with injector timing etc.

Any tips???

Is the MAP sensor calibrated correctly? What does it read when the engine is stopped?
