error message: ING0_FALLING

[Remmele]

Hallo,

we are complete new with the vems ecu. No we try to start our first engine and we have the following problems.









Engine runs on all 4 cylinders only roundabout 5 - 10 sec.
After trying to start the engine ineffective we have the above mentioned error messages in vems trigger lock.

Technical datas:
4-cylinder boxer engine
4 cylinder wastet spark
VEMS board V3.6

Thank you very much for your help.

for the start, set you connection speed to faster one if you want to log trigger on working engine, second, describe your setup properly and post log of cranking or running when that happens

If runs only 5-10s, then you have to less fuel(wrong reg_fuel or VE table or warmup enrichment). For 5-10s is after start enrichment.

First of all, "IGN0_Falling" is not an error message, it is a ignition event (falling edge, usually when spark is released).

Thank your for your answers.



Hope this picture helps you.

We checked the VE and warmup enrichment. They seem right.
We also tried some req_fuel setups. None of them work.
Does it help if i post the VE/warmup enrichment tables?

Also we tried to change the ignition timing. It changes in the interface, but checking it on the running engine it shows the old timings.

Another thing we just mentioned is the MAP-sensor. We dont have the sensor installed. But the measured value rises after activating ignition (turning the carkeys). Starting the engine before the value rises works. Starting the engine at a high value doesnt. Could this be a reason for the problem? 

Thank you for your help!

yes, you have over boost fuel cut protection.

and you get map multiplication too, set map sensor calibration value to 0
