Hi!
My name is Sam Johnson. I live in Victoria BC, Canada.
My project is an Onroad/Offroad Jeep. I am installing a GM 4.3L V6 engine
- sequential EFI (Bosch 0.280.155.968 injectors)
- wasted spark ignition (Bosch 3x2 coil)
- a single Masterpower MPR R6164-12 turbo, 60mm external wastegate (with 4 way boost control solenoid)
- Air to Water aftercooler.
Trigger
- 60-2 crank
- 4x cam sensor (?)
- can you detail this ? Is that a VVTI V6 with 4 cams (2 intake + 2 exhaust sensors ) ?
- or 1 camsensor with 4 pulse-pattern ? How are the pulses timed (they should not be evenly spaced, at least that does not make sense for camsync/secondary trigger)
- secignore can be used to neglect eg. tooth > 13 (just an example), but of course sectrig pulse should only come every 2nd crankrot (tooth 0-12 in the example)
There is a single cam sensor with an unevenly spaced 4 pulse-pattern. Here is a picture of the cam reluctor:
I am making an effort to find a waveform depicting the cam pulses referenced to crank position.
Hoping to use VEMS genboard to control the engine with wideband EGO feedback and pre-turbo EGT thermocouple for tuning. I intend to get anti-lag working with my 3 speed automatic transmission (obviously anti-lag NOT required for shifts, only for closed-throttle deceleration and launch.)
Also hoping to use genboard on-board MAP sensor for dynamic BARO correction with an engine-mounted Bosch TMAP (2.5 Bar) as the primary MAP sensor.
- baro correction can use external sensor (115 kPa, or same range as internal MAP sensor are most common to use, but... )
Do you mean to say " baro correction can use INTERNAL sensor " ?
Also of possible interest to the community is my effort to model the engine in Ricardo WAVE. I have a working model now but am still calibrating with dyno logs from similar engines. Once calibration is complete, I hope to link the model to a SIMULINK model of the VEMS. Has anyone modelled the VEMS firmware in SIMULINK?
- Probably not
