Summary of change:
'''trying to start engine - no rpm reading in MT''' *Is there anything in the primary or secondary trigger settings that is incorrect? *Wiring to Crank Home is verified: Pin 1=Red, Pin 2=Violet *Sensor measures 1,087 Ohms across Pins 1-2. *Sorry, no dumps (my fault) all I have is the .msq : http://www.vems.hu/files/KevinBlack/ChrisGreggFinal.msq '''Also screen shots of MT Trigger Config''' http://www.vems.hu/files/KevinBlack/PrimaryTrig.jpg http://www.vems.hu/files/KevinBlack/SecondaryTrig.jpg '''Secondary trigger says "Disabled" - is this correct?''' ---- '''Car Information:''' * 1991 Audi 200 20vtq,(3B) * Stock injectors, 3.5 bar fuel pressure * 5 individual 12V power coils ---- ''''ECU information'''' * Webshop assembled Serial # 2016 * 1.1.27 Firmware * Marcell config and tables for 3B * Megatune 1.1.23 and or V3GUI for tuning ---- '''Questions:''' * Does 3B Engine need crankhome wires reversed? ** yes * What is Cam Hall inversion? ** a small (NPN) inverter inside the box makes low/hi from hi/low input (on EC36/13) * Need to check config (Marcells config shows 90 tooth for trigger? I thought it is 135 tooth?) ** actually 270 tooth, so 90 because of the divby3 * Need to verify all trigger functions - shipping this ecu to a customer ** you can use soundcard, left channel to EC36/27, right channel to EC18/12. Use c270 trigger * Need documentation about how P259, INJ, etc. is wired to Motronic55 connector ** See the 3B column in the spreadsheet. http://vems.hu/download/v3/Motronic55/motronic-AAN-ECxx.xls ** also see the functions in the config. Eg p259/0 (ec36/4) is tach out. ** also keep track of what you ordered. The SSC6 pinout can vary according to customer request (pins can be analog input, or ignout logiclevel/power ign out, or gnd) ---- '''Requested Configuration''' MAP connection 400kPa onboard - brass nipple Flyback - 30v Diode LCD - Connector through endplate (DSUB9 on endplate or flying loom) EGT - Flying Loom through endplate Knock - Via Motronic55 Pins IAT - Audi PTC Sensor (430 Ohm pull-up) ---- '''Ignition Configuration, 5 IGBT Outputs''' '''IGN Output - EC36 - Color - Cylinder''' 10 - 33 - Blue(Tape) - Cyl 1 20 - 34 - Black - Cyl 2 30 - 36 - Brown - Cyl 4 60 - 24 - Red - Cyl 5 70 - 10 - Blue - Cyl 3 Firing Order 1-2-4-5-3 ---- '''2 Analog Inputs, custom connector''' * Red (Analog ?) 8,400 Ohms to Pin 12 5V * Blue(Analog ?) 8,400 Ohms to Pin 12 5V ---- '''Launch Control and Shift Cut Setup''' * '''How do I wire and set-up the Launch/Shift as described below?''' 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. ---- '''WBO2 Configuration''' '''SSC Pin - Flying Lead - WB02 Pin''' * 1,black Nernst,WBO2 Pin 1 * 2,'''White''' +12V (motronic pin27) 3 * 3,'''Grey''' Heater(-),WBO2 Pin 4 * 4,transparent Pump(-),WBO2 Pin 5 * 5,thin red Pump(+),WBO2 Pin 6 ---- '''Suggestion - make WBO2 wire colors match the LSU4.2 sensor''' '''SSC - Color - WBO2 Pin''' * 1 - Black - 1 * 2 - Grey - 3 * 3 - White - 4 * 4 - Yellow - 5 * 5 - Red - 6 ---- '''General Audi Information''' 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
