I just finished up the wiring on my Audi A4 b6 2.7 L engine swap.
I'm at a loss. I'm running a AEM wide band o2 sensor and using the 5 volt signal to the ecu.

I checked the injectors and they are working, I'm not getting anything with rpm...

The fuel pump is firing up and I'm getting pressure to the fuel lines. I going to be checking the ignition coils this weekend.

I'm second guessing myself now and I'm wondering if there is something I'm missing. any input would be get.

On the monitor screen, the box that says #trigs says 0. Your ecu is not reading rpms and will not fire the coils or injectors. What do you have for a crankshaft sensor and has it been correctly configured in the ECU settings?

The fuel pump turns off after a few seconds of not seeing a rpm reading.

For my cam/hall sensor I'm using the stock sensor.
Pin 1- hall sensor positive
Pin 2- cam shafts TDC trigger index phase angle
Pin 3- hall negative / shield

I'm second guessing the crank position sensor

Pin 1-
Pin 2-
Pin 3-



On this
Pin 1- VR output
Pin 2-VR Negative
Pin 3- Shield



Pin 1- (220) Ground connections
Pin 2- blue wire
Pin 3-gray wire
