No start- erratic crank signal
« on: September 06, 2017, 02:31:40 pm »
Hey guys,

So Ive swapped a volvo t5 motor into my e36. Got vems all wired up but I have ano start condition. Injectors click and fire as they should. I only have spark at immediate cranking and right at the end of cranking as I turn the key off. RPM signal is all over the map, which would cause the erratic spark. Right nos I do not have the computer we are using to tune in front of me but I will grab firmware version asap. Attached I have my config and a log of cranking.

OEM volvo coils
Factory VR crank sensor
Factory hall cam sensor
15th tooth is cylinder 1 TDC.

No idea how to attach the config and logs. If someone could help that would be great or I can email them.

Upload a image of the triggerlog as a image.
Your problem might be the crank sensor, as it is a known problem on these machines.
