Hello guys,
Today we wre dynoing my BMW 545 where fuel and ignition is controlled by a piggyback ecu. We noticed that at 5000 rpm the throttle was only open around 50% despite 100% pedal position. And of course we only measured the half of the expected power. We started thinking, read the original ECU and I found a Torque request map. Attached. 3D map of RPM and pedal%, result is power%. As I'm not so experianced in reflashing could you confirm or deny me? I'm thinking because of this map, the tps will be only opened maximum 50% despite higher pedal%.
Bosch ME 9.2 ECU BMW N62 engine. MAF removed so instead of valvetronic, car running in conventional throttle body mode.
Thanks in advance!

Hey hope you are well
It sounds like you are looking for a torque limiting map. Not request
Basically it sounds like the car is hitting a torque limit. Ecu gets confused and cuts throttle to bring the car back below the torque limiter.
I think the map got some errors, do you use the cracked ecm titanuem?! If so thats the problem.
Thanks guys! Yes, I tried it on a cracked version... I thought also on this. So started searching a company who has a legal version of the ECM Titanium.
