Summary of change:
Planning VEMS 3.3 for turbocharging BMW M50B25 engine in an BMW E36. Lives in Sweden Gothenburg. '''Enigne Spec:''' *M50b25 without vanos *Je Forged Pistons Compression 8,1:0 *MLS headgaskset 1,8mm *ARP headstuds *500cc injector *Preicison Turbo SC-44 *Tial 38mm wastegate *50mm PPF blow-off. *600x300x75mm intercooler *Sachs heavy pressureplate 240mm *Organic disc 550nm *Walbro 255l/h fuelpump *Primary trigger: VR *Cam Trigger: VR Q: Is about to configure the megatune settings and how do I set this injectors settings: Usings Precision Turbo 500cc@3.5bar High-z. *Inj open time @13.2V(us): *Inj effective rampup(us): *Inj battfac_rampup(us) *Battfac: *Injpwm DC(%): *Injpwm DC added@6v(%): *Injpwm time (ms): *Injpwm peak time(ms): Q: And settings for the COP:s *Coil chargetime: 3ms is this a good starting value? *Coil chargetime added @6v: ? Q: The wiring is almost done, 80% done. Have made a piout table, but unsure about how to wire the knock A&B. Also unsure about the Idle Air Control Valve. It's a Bosch 0 280 140 545 1738 981. It has 3 pins. I guess one is ground, the second 12v supply and the third should be connect to injector #7 or #8? * is it same as MembersPage/GergelyLezsak/IdleControl ? Q: I measured the trigger angle 60 degrees before TDC. * that is perfect, 40..100 degrees are OK, and 40..60degrees is the best. Q: I want a tachometer signal to the stock rpm gauge. How should i set this up? Is there an output for this, and can vems handle this when I'm using COP? * use a separate output, and configure config.tach_channel and config.tach_divider; If you have no luck (review, measure, publish, but) consider that some RPM gauges require high input voltage signal which can be derived from the ignition transformer primary (using a few diodes).
