Yes that's normal. You are now mixing up output numbers and cylinder numbers. Don't worry. It's classic mistake to make. Speeduino fires injectors and coils in numeric order. Like basically any other aftermarket ecu does. Firing order in bmw m5x is 1,5,3,6,2,4 by cylinder number, so the inj/ing output 1 is wired to cyl 1. Inj/ing output 2 is wired to cyl 5 and so on:diablospeed wrote: ↑Fri Aug 12, 2022 10:58 amI had a Speeduino MS41 REV3.0B made by JLC PCB and i use M54 cam sensor.
The problem is that i can't get the engine to run properly, i tested a lot of configuration in tuner studio (engine constants, trigger setup...), and i read all your documents but the engine does not run well. It crank and start but, opération is erratic.
I saw the last Firmware on Github 202207 and i used it. The engine runs on its 6 cylinders but not perfectly.
I searched a lot for solutions, but i'don't find where is the problem. I tried with Arduino IDE, manual compiling firmware (global.h: INJ-6 IGNI-3) , No result.
I ended up realizing by watching led flashing that the engine is out of sync. Injection séquence is currently: 123456 whereas it should be 153624 ? like ignition ?
The ignition pairing is weird too, currently : 1-4, 2-5, 3-6 .
It'a firmware problem ? or what else ?
I also bought it. It does what it's supposed to. T[…]
