Summary of change:
'''Bmw m3 s54b32 install guidelines:''' Use properly sized fuses everywhere. * ETC motor: max 15A * ign: 4A (might change to 5A after all tuned) * inj: 3A '''Wiring up ''' * Trigger: ** connect primary trigger to crank vr sensor ** connect secondary trigger to exhaust cam hall sensor ** connect third trigger to intake cam hall sensor * Sensors ** wire up clt ** wire up iat ** wire up ETC tps on end of ITBS on engine ** wire up ETC tps2 inside ETC actuator ** wire up ETC pedal pps1 ** wire up ETC pedal pps2 ** wire up wbo2 1 (and 2 if used) * Output guidelines: ** use separate ignition outputs for all coils ** use separate injector outputs for all injectors ** use injector outputs with external Schottky diode flyback for Bosch three wire IAC valve (when used) * Fuses ** ETC supply should be suitable fused 15a ** Use suitable fuses for all other outputs (output groups INJ/IGN/IAC/WBO2) '''Testing''' * calibrate curves for clt/iat * calibrate tps/pps1 * set safety curves tps2/pps2 * make triggerlog in VemsTune during cranking (crank for 5 seconds or more). When everything is connected properly (trigger wise) triggerlog should look like this: * http://www.vems.hu/files/BMW/s54triggerlog.png * when anything looks different than this report before proceed. '''Setup / Tuning''' * Should be the same as any other engine with variable cams on both axis and high compression. Time consuming. ######## sorry for disasembling your ecu, just wondering where that white wire should be connected (red circle) big capacitor + , and does that track on pcb must be cut? http://s10.postimg.org/hglxak4dl/DSC_1074.jpg The trace should be cut and solder the white wire into pin 2 of the same chip. (The trace was cut because of that wire.) on hold. engine needs rebuild.
