Running questions and trouble
60-2 no camsync, 4 cylinder using firmware 1.0.69
- batch injection
- why don't you run the 4 injectors at different times from 4 outputs (and only use batch during cranking)
- wasted spark ignition.
Relevant config:
primary_trigger=01
secondary_trigger=02
tooth_wheel=3A
trigger_tooth=02
another_trigger_tooth=1E
- BAD: crank_minper=EA (might get you unintentianal revlimit)
- crank_minper=00 will do fine
- BAD: tooth_wheel_twidth1=02
- tooth_wheel_twidth1=18 (decimal 24, that is 6 degrees)
- BAD: tooth_wheel_twidth2=06
- tooth_wheel_twidth2=48 (decimal 72, that is 18 degrees)
- BAD: ign_tdcdelay=D8
- use 55 .. 65 degrees, and adjust trigger_tooth accordingly
ign_out=70
- ignchmax=01
- prefer ignchmax=03
h[0]=0F 00 00 00 00 00 00 00
h[2]=00 10 00 10 00 10 00 10
The first (zeroth if you like) tooth after the missing tooth occurs (at the sensor) 120 degrees (???) that is 20 teeth BTDC. Verify this! It's not the middle of the missing tooth that counts.
- BAD: trigger_tooth=02 and ign_tdcdelay 0xD8 (216 * 0.5 = 108 degrees). The sum would be good: 12 + 108 = 120 degrees but timing from a tooth too early is not good (especially during cranking)
- good: trigger_tooth=0A and ign_tdcdelay=0x78 (10*6 + 120*0.5 = 120 degrees)
Now the engine won't start and will kick back during cranking. For some reason I tried ign_tdcdelay = 0x5A (90 * 0.5 = 45 degrees). Together with trigger_tooth this makes 12 + 45 = +- 60 degrees) which happens to be half the real value of 120 degrees. The engine is running sweet then, especially at increased engine revs.
Q. Although the engine is running I would like to know what mistake I made. Did I use the wrong factor (2 instead of 0.5) or something else is wrong.
- can you strobe the engine ?
- maybe the angle is not 120 degrees ?
- do you count from the proper point ?
