Honda Civic with Microsquirt, timing problems, help needed
Posted: Wed Jan 03, 2018 1:46 pm
Got an old ATEcu Microsquirt with somekind of extra relay card installed to Honda Civic CRX and i´m having timing issues.
I have welded a toothed wheel 36-1 to crank pulley so that the 1st tooth is at 90 degrees BTDC, also included VR-sensor at 70 BTDC. Have set 1st tooth angle to 90 degrees. Got it running with horrible pedal pumping and then i checked the timing with strobo and i had to increase advance in timing table to what i think is way too much. But only with that advance i got it idling about 1300 rpm. And at that time i checked the advance with lamp and the 0 degree timing mark is at TDC. SO base timing is not correct. Ignition is VAG wasted spark coil and i have tested that i have spark and fuel, but the timing is just way out?
After little idling, I shut down the engine and after that i haven’t got it running.
I have updated firmware to 3.4.2. tested with same tune but doesn’t start. Cranking feels and sounds like timing is out like way out…
Some questions…
So how i can get the base timing in order? I have tried to adjust the 1st tooth angle to get base timing in order, but it doesn’t have any effect for timing? And if you experts know does ECU need a powercycle before that 1st tooth angle change takes effect, ECU doesn't alarm about powercycle as in other parameters changes.
And of course am i using a wrong parameters for ignition?
Should i move VR-sensor exactly to 90 degrees BTDC as where the first tooth is or does it really matter where the vr sensor is because ECU knows that first tooth place already... is this a problem? Or is there something huge wrong in my setup? Attached msq with which i got engine idling. I don´t have log for idling but earlier log is uploaded when i was trying to get engine running but it was not idling good.
