Hi, i've build Speeduino based v2.1 PNP ECU by Pazi88. Using 201810 firmware with Pazi88 base tune from github. Car is M52B28 Fully swapped(ms41.0 ecu, sensors, maf, wiring loom) BMW E34. M50B25 intake manifold, M54B30 Purple Head (252cc/min) injectors. Engine doesn't start. By the way i dont have autotune to tune it. Where is my mistake? or i just need to tune it for start?

Hmm seems like Cranking maps are wrong or firing order , are there settings for Trigger wheel set up correctly 60-2 ? Also Injector's deadtime map and Fuel Cranking map have to be changed to M54B30 maps.

Hi. The trigger angle should be 276°. So the 36° you have in the picture is wrong.

Cheers.
