Summary of change:
Project description: Drift car BMW with swapped '''AMG 6,3 V8 engine'''. '''Engine is from Mercedes E-class w211 AMG m156 6,3 v8, year 2002-2009''' ---- Engine is and will be completely stock. Engine configuration: * 2x DOHC V8 with 4x variable cams and 4x cam sensors * 8x individual coils * Variable intake or swirl flaps (not clear now, but i will check it later - but this is not problem for now) * 2x Electronic throttle bodies ** '''VEMS is one of the very few ECUs that can control 2 x DBW (ETC) electronic throttle bodies, via CAN-bus: the [https://vems.hu/vt/help/v3/v3_electronic_throttle_control.html BMW S65 type]''' http://www.vems.hu/files/LanciaSlovakia/AMG%20V8/1015px-Mercedes-Benz_M156_Engine_02.JPG http://www.vems.hu/files/LanciaSlovakia/AMG%20V8/engine%20detail.jpg ---- '''Ignition coil datasheet or pinout''' I don't know if they are active or passive. My tip is that they are active, but '''can someone please provide info ?''' * if you can measure appr 0.6 .. 0.8 Ohm resistance between 2 pins (same in both directions; Also high inductance but that cannot be measured easily with most DVM), they are passive; otherwise active. This should be the '''coil number: Bosch 0 986 221 128 - 4pin connector''' http://www.vems.hu/files/LanciaSlovakia/AMG%20V8/ign%20coil.jpg ---- '''Two electronic throttle bodies'''. Is there any possibility to buy Vems which can control two throttle bodies? * '''VEMS is one of the very few ECUs that can control 2 x DBW (ETC) electronic throttle bodies, via CAN-bus: the [https://vems.hu/vt/help/v3/v3_electronic_throttle_control.html BMW S65 type DBW]''' Any ideas how to connect two throttle bodies to the Vems? I have 1 idea, but i dont know if it will work. My idea is on wiring diagram picture below. http://www.vems.hu/files/LanciaSlovakia/AMG%20V8/throttle%20bodies%20wiring.jpg http://www.vems.hu/files/LanciaSlovakia/AMG%20V8/throttle%20bodies.jpg * However, currently only 1 dummy DBW/ETC throttles can be controlled via current firmware and 1 ECU. ** 2 VEMS ECUs can control 2 dummy DBW/ETC throttles (all, or most of the tables can be identical in the ECUs, and can be tuned simultaneously in one go; with some setup task, and saving separately, for comparison/verification). ** standalone controller can also be used for the 2nd throttle (o r both), to follow the same PPS => TPS curve. Some [http://vems.hu/download/DBW/ElectronicThrottleModule/HU/ example standalone] we've seen in use earlier (not sure if still available, or where the English doc is). ** It would be extremely important to specify if there are any special functions planned (ALS, or similar) that overrides normal PPS => TPS function. ---- '''VVT''' . I don't know the type of Variable Valve technology of this engine. It looks like 4 solenoids and 4 camshaft sensors. But i have no idea how these triggers works. Does anybody here have any repair manual and wiring diagrams for this engine and especialy for vvt technology and its logic? http://www.vems.hu/files/LanciaSlovakia/AMG%20V8/vvt1.jpg http://www.vems.hu/files/LanciaSlovakia/AMG%20V8/vvt2.jpg http://www.vems.hu/files/LanciaSlovakia/AMG%20V8/vvt3.jpg http://www.vems.hu/files/LanciaSlovakia/AMG%20V8/vvt4.jpg '''VEM can control 4 cams (2 exhaust, 2 intake), with feedback from 4 cam-sensors (5 triggers total)'''. There is no indication so far that there is any problem to control these with VEMS ECU, but exact pulsetrain information would make it more assuring. ---- Problem Nr.4: Which trigger settings i should use in vems tune? There are many trigger teeth at cam wheels as you can see on pictures below. http://www.vems.hu/files/LanciaSlovakia/AMG%20V8/vvt6.jpg http://www.vems.hu/files/LanciaSlovakia/AMG%20V8/vvt5.jpg Can you capture triggerlog ? (or provide numeric angular positions ?) ---- Please, i need help from vems group or anybody with experiences with these engines. I would like to order the ECU, but want to order the right configuration without mistakes.
