Summary of change:
Trying to get VEMS to run in a plug and play fashion on a 1997 Seat Cordoba SX, with a 2.0-16V engine (engine code ABF). The sensors, actuators and required outputs are: *Hall-effect type crank sensor on a 60-2 trigger wheel *Hall-effect sensor on camshaft for sync *Bosch coolant and air intake NTC temperature sensors *Single dumb bosch coil triggered with external module, and with ECU controlled dwell (but swapping to waste-spark now so need 2 high current ignition drivers) *Two bosch 3-wire knock sensors *RPM signal from ECU to instrument cluster to drive tachometer *2-wire 4-ohm Bosch idle control valve *currently 440cc highZ injectors, but hopefully the VEMS will be able to idle the new lowZ 720cc injectors without problems *eventually the engine will experience up to 2 bar boost so 250kpa transducer inadequate Extra I/O required: *high current PWM driver for aquamist water injection high speed valve *shiftlight *IAT based output to drive intercooler spray solenoid *Boost control using cosworth or Saab solenoid *one EGT using k-type TC in exhaust manifold *noritake VFD 4x20 LCD-pin-compatible display *one wideband bosch LSU4 sensor Table of VW pinouts corresponding to VEMS pinouts: ||Description||ABF ECU||VEMS|| ||Main grounds||T68/1||EC36-5,21,32,22|| ||Sensor grounds||T68/33||EC36-26|| ||Air temp sensor||T68/36||EC36-?|| ||Coolant sensor||T68/14||EC36-14|| ||TPS signal||T68/40||EC36-40|| ||Crank sensor power||T68/38||EC36-?|| ||Crank sensor signal||T68/??||EC36-??|| ||Switched 12v power||T68/38||EC36-25|| ||TPS reference voltage||T68/41||EC36-28|| ||Ignition coil output||T68/8||EC36-35|| ||Idle control valve||T68/27||EC36-??|| ||Injector 1||T68/24||EC36-7|| ||Injector 2||T68/25||EC36-19|| ||Injector 3||T68/26||EC36-8|| ||Injector 4||T68/2||EC36-20|| ||Injector common||?||EC36-23|| ||Fuel pump relay||T68/6||EC36-15|| ||Tachometer signal to cluster||T68/22||EC36-?|| ||Knock sensor 1 signal||T68/34||EC18-3|| ||Knock sensor 1 ground||T68/32,10||EC18-2|| ||Knock sensor 2 signal||T68/57||EC18-3|| ||Knock sensor 2 ground||T68/55,56||EC18-2|| ||Charcoal canister||T68/31||EC36-?
