DIYPNP Startup Issues - BP4W, 410cc, NA6 chassis
Alright, I'm having some issues that really have me confused.
Freshly built BP4W
RDX 410cc injectors
NB cam / crank sensors
Car was previously running this ECU on an NA8 engine with stock ECU and sequential fuel.
Using output test:
Injector 1 -> Cylinder 1
Injector 2 -> Cylinder 3
Injector 3 -> Cylinder 4
Injector 4 -> Cylinder 2
Coil A sparks cyl 1 & 4
Coil B sparks cyl 2 & 3
Calculated req fuel is 7.8ms.
Car would crank / no start. When I flipped trigger angle to 180*, and fattened req fuel to ~12ms, I could get it to start. It ran fairly rough, like it was running on two cylinders. Plugs 1 & 4 show very rich (but running), 2 and 3 covered in soot.
I'm assuming the 180* trigger angle means I have the coil outputs swapped? I tried swapping the plug wires to the opposite coil and running 0* trigger angle, but fared no better.
All of my sensors, TPS, CLT, and IAT are calibrated and reading correctly.
Thanks in advance for any help, msq attached.
