Summary of change:
This topic has started as request assistance with buy to choose all options correctly. However I will need probably more assistance so would like also share gained information with others to help with further installations. '''Goal''': Fit VEMS to control BMW M62B44(no Vanos) modified engine but still natural aspirated. hint: when installing, make it separate page for each project (to avoid disambiguaty) '''Stock M62 parameters:''' *** V8 *** DOHC without VANOS *** STOCK ECU BOSCH DME M5.2 *** Fully sequential injection *** 8 coils "passive" *** ABS ring wheel speed signal (direct) *** Idle : ZWD "idle speed is controlled on the M62 engine by means of a two-winding rotary actuator" Stock signals: *Inputs ***Crank sensor : VR reading signal from flywheel ***Cam sensor : Hall reading signal from intake cam cylinder 1to4 *** 1x TPS *** MAT *** CLT *** 4channel Knock *** 2x Narrow band *Outputs ***Coil direct to spark, have a build in IGBT drivers(8 totally) ***Injectors are High impedance/ High-Z *** Idle valve (ZWD two-winding rotary actuator) ---- '''Target M62 parameters:''' * NA * Stock '''VR Crank sensor''' * Stock '''HALL Cam sensor''' * 8x Stock Passive Coils * '''Stock Idle control''' (13 41 1 733 090) ** is that dual solenoid ? * ITB from S62 also with injectors High-Z * Alfa N * Intake air pressure * Electric accelerator pedal module (35 42 6 786 281) * Drive by Wire actuator from S62 (12 72 7 831 246) ** CAN-bus type like S65/S68 ? ** or traditional dummy (non CAN-bus) to drive with VEMS Bridge Output driver ? * 2x wide band * 2x EGT * 2x Knock * Flat shift Signals: *Inputs *** Crank sensor : VR reading signal from flywheel *** Cam sensor : Hall reading signal from intake cam cylinder 1to4 *** 2x Wide Band closed loop *** 2x EGT *** 1x TPS *** MAT *** CLT *** 2channel Knock *** Electric accelerator pedal module - double resistor *** '''CAN bus''' (for 1 CAN IAC-valve and 2*CAN throttles ?) *** Speed sensing S62 ABS rings on rear axle *** Fuel Pressure *** Oil Pressure *** Oil Temperature *Outputs ***Coil direct to spark, need IGBT driver (8 totally) ***Injectors are High impedance/ High-Z *** Idle valve (ZWD two-winding rotary actuator) *** Throttle actuator Control (BridgeOutputDriver) *** PWM FAN control *** CAN bus (Signal for S54 instrument cluster) *** Alarm control/signal “LED” ---- Dominik's Mercedes V8 engine (sounds like this section should move to separate page): * can we implement 8 high current [https://shop.vems.hu/catalog/ignition-driver-p-49.html ignition drivers] => those would be able to control 2 ignition coils each. * can we add 8 further ignition drivers to to the 8 ignition outputs (2 parallel on each output)? yes, Either * order with 0 IGBT (8 logiclevel), and order * [https://shop.vems.hu/catalog/clamping-plate-p-62.html 3 clamping plates] * and 1 [https://shop.vems.hu/catalog/ignition-driver-insulator-sheet-p-75.html insulatorsheet] (3 lines)" ** this allows using an external heatsink to mount 16 IGBTs in 3 lines OR * order with 8 IGBT , and order comment: "please wire the 8 internal LOGICLEVEL IGBT gate-drives to flying loom EC10 connector, and add 2 clamping plates, and 1 insulatorsheet (2 lines)" ** this allows using an external heatsink to mount 8 IGBTs in 2 lines Alternatively request "200 mm long flanged box". Either to fit 16 IGBT-s inside ECU, or 2 complete VEMS ECU-s (also provides redundancy) * 2 ECU would fit siamese in 100mm long extrusion (one to front and one to back: with external MAP sensor) ** or if driving total 16 passive ignition coils (from 8 or 16 ignition IGBTs, either from 1 or 2 ECUs) the 200mm => added surface provides more "thermal room" for slightly longer dwell (during long rally sessions, under suboptimal conditions, eg. >80C). ** with careful installation and measurements + testing: possible to drive 2*8 passive igncoils from 8 IGBTs even from standard VEMS ECU : too high dwell (configured) would result in insufficient cooling situation ---- * other M62b44 projects MembersPage/Qualitec ----------- 08/6/2016 Update ----------- '''Modified M62 parameters:''' Displacement changed to 4734cc Injectors 257 cc/min 12ohm (Stock S62) Firing order 1-5-4-8-6-3-7-2 http://www.vems.hu/files/MembersPage/Matus/IMG_8590.JPG '''Modified ECU parameters:''' I have decide to change case as there was lot of components connected by flying looms.
