- Wiring complete,sensors working,i can see the gauges in Megatune,but there is no RPM signal yet (can wrong calibration (60-2 instead of 5 window) cause this?)
- primary_trigger=FF (or FE if falling edge is used). The primary_trigger=01 is for multitooth (eg 60-2 missing-tooth) setup
- secondary_trigger=02
- TPS reads 10% after calibration,is this normal?
- of course NOT! increase tps_low
wishes for next v3.x ECM
- primary trigger: VR crank 60-2 (changeable to HALL with dip switch if possible, so only the endplate needs to be removed)
- High voltage flyback (2+6diode)
- All 8 ignition/injector channels
- EGT and Knock
- 4bar MAP sensor onboard
- Programmable Shift light output (a p259 channel)
- baro (altitude) compensation: MAP measurement at startup. Separate baro sensor is not justified when you have WBO2: when we tune at (say) 200m above sea level, we add +10% fuel in the VE table, so ego_correction=-10% (-25 on display) that is good to appr. 5000m, and normally the WBO2 based ego correction will take away as much of the extra fuel as necessary.
under investigation:
- WBO2 analog output (for DVM or other ECM), eg.
- lambda=0.6 .. 1.45 => 0.6V .. 1.45V
- 1.45V .. 1.499V not used
- O2%=15..21% => 1.5V .. 2.1V (or should it be max 1.96V so the DVM can be left in 2V mode? maybe configurable)
- below < 0.55V: measurement error (eg. WBO2 sensor not heated). Alternatively this condition could be mapped to >2.5V for better margin, but when WBO2 controller is unpowered, 0V is "easier" to maintain
- Warning light output: activates when any measured data (that I list here) exceeeds it's programmable warning treshold:
- CLT: engine too hot
- EGT: exhaust too hot
- MAP: boost too high (BoostController misconfigured, or pneumatic problem)
