Title: Auditrigger-engine not starting
Post by: Reini1977 on January 29, 2020, 08:46:14 pm

hi all

built a new I5 20V motor, FW 1.2.38

i have rpm signal, i have fuel injection, i have spark, but engine behave as following

when i set cam sync wheel to TDC (wrong setup) , engine starts, but a bit on the gas, and i get trigger errors

when i set cam sync so, that the hall sensor is in the window exactly when crankhome pin is on the VR sensor (setup correct like factory), i can do what i want, the engine doenst start

tried everything, richening up, leaning out, use different offset angles, nothing

it sounds like from time to time i have a hissing noise in the exhaust, but nothing more

can you give me a direction?

regards

Upload a config and trigger log.
Did you change polarity of tdc home sensor?

thank you

will do so, when i have access to my Notebook again..tomorrow

yes, swapped the polarity, can verify with scope if necessary...

also, i have a nice trigger signal and rpm

plugs are firing, injectors are working

is it possible that i have to shift the ignition order?

regards
