Summary of change:
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: http://www.eficonnection.com/eficonnection/images/4x_Cam_Reluctor_300w.jpg 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... ) ** See [http://www.vems.hu/vt/help/v3/v3_engine_setup.html Barometric Pressure Correction] 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
