Summary of change:
I'm looking to use the VEMS Motronic PnP on a 1991 Audi 200 20v turbo, the motor is a 3B * Can the VEMS Motronic PnP be adapted to this engine (harness) ? ** Yes, developers actually have a 3B test engine (that is 20VT engine with 3B harness) for testing several stuff: MembersPage/MarcellGal/PowerAndTraction Pic of ECU Connector: http://www.vems.hu/files/Audi%203B%20Connector/ECUconnector.jpg 3B Wiring Pinout: http://www.s2central.net/motronic_pinout_3B.html 3B Wiring Schematic: http://www.s2central.net/images/3B_ECU_Schematic.jpg Audi 3B Information: http://www.s2central.net/motronic_02.html http://www.sjmautotechnik.com/trouble_shooting/20vboost.html ---- '''For 3B, specify choice for the extra SSC6 connector''' MembersPage/TeppoKalske page bottom has the standards for SSC6 female pinout: * either "3B ECU extra connector pins" * or "AAN ECU extra connector pins" Or "your custom pinout you like, eg. 4 outputs and 1 analog input" and 1 GND. As you see, the "AAN ECU extra connector pins" has 3 analog inputs, we use one brake-light switch mounted under clutch (and a series switch that can disable it) to pull down (activate) the (shared) input for shiftcut and launch. When activated with TPS < iac_tps_threshold launch is activated (TPS can be pressed after activation). Otherwise shiftcut is activated. In any case, one must specify his extra-connector pinout preference for a 3B engine. ---- ---- ---- '''VEMS Motronic Audi 3B ECU Configuration''' MAP connection 400kPa onboard - brass nipple Best Flyback (Trans Diode) for "630 Pencil Injectors" LCD - Connector through endplate (DSUB9 with flying loom) PS2 - Flying Loom through endplate EGT - Flying Loom through endplate Knock - Via Motronic55 Pins IAT - Audi PTC Sensor (430 Ohm pull-up) ---- '''Custom Pinout''' '''WB02''' Flying Lead (No connector, I will supply) * Nernst,WBO2 Pin 1 * WBO2 Pin 3 (use a 5A fuse from +12V supply wire) ** red wire from +12V flyback (motronic pin37) * Heater(-),WBO2 Pin 4 * Pump(-),WBO2 Pin 5 * Pump(+),WBO2 Pin 6 '''IGNITION''' Motronic55, Pin 1 is Stepper D, EC18 Pin 11 Flying Lead (No connector, I will supply) * Stepper A, EC18 Pin 4 * Stepper B, EC18 Pin 10 * Stepper C, EC18 Pin 5 * EC36 Pin 11 (Logic level) * analog input with pullup * analog input with pullup ---- '''analog input usage: Launch Control / WOT Shift Cut''' Flying Lead (No connector, I will supply) * Analog Input for: "Brake-light switch mounted under clutch (and a series switch that can disable it) to pull down (activate) the (shared) input for Shift Cut and Launch. ** When activated with TPS < iac_tps_threshold launch is activated (TPS can be pressed after activation).
