How EMU determines its current state

Post by grabski » Fri Jun 09, 2017 2:25 pm

Hi all, i wonder how EMU determines cranking stage. Set up all wires, but when the starter works i don't see any EMU stages in status bar except INACTIVE. Looks like stages should change due to RPM change... if yes i think i need to check my triggers (primary and secondary)

Tried to use SCOPE tool to check my HALL sensors but looks it doesn't work when EMU status is INACTIVE :roll:

Thanks!

yes your crank sensor needs to be working and the ecu getting a signal then it will indicate "SYNCRONIZING" or "SYNCRONIZED" when its cranking or running and you will see the cranking rpm on the logging trace

if you have HALL sensor then you will need to "enable pullup" in the settings

Thank you a lot for clarification. I guess i have problems with triggers setup. I have 116 teeth BMW M30 flywheel like

In primary trigger tab i used "BMW e30 M3 116 teeth" and not sure how to sync it with reference pin... should i use secondary trigger tab for it? Do you have any thoughts?

Thank you!

camsync will need to be "2 symmetrical teeth" even though there is only one pin it is on the crank not the cam so it will still pass the sensor twice every full 720 degree cycle.

you will only be able to use wast spark and semi sequential (squirt twice per cycle)

Also I think you will find both sensors are VR sensors, unless you have changed them

Omg, you are god damn right about 2 symmetrical teeth! As for ignition and flueling - yep im using DIS ciol pack + semi seq injection. BTW 5 days ago i ordered 60 teeth -2 trigger :lol: :lol: :lol:
