Skoda Octavia dedicated track race car with
- VAG Audi 1.8L 4cyl 20valve NA engine
- WBO2
- EGT
- LCD
- knock-detect
- heavily modified intake system (individual throttle bodies,no airbox or filter)
- Kit-car exhaust manifold (very long 4 to 1 design)
The engine is currently not controlled with
There would be appr. 6 similar installs within a year if all goes well.
Trigger setup - under investigation
- maybe 60-2 VR on crank - must be confirmed
- maybe 1-pulse HALL on cam - must be confirmed
The genboard is wired up except the crank VR (hopefully a 60-2),WBO2,EGT,injectors and coils.It communicates with the megatune,TPS,batterycalibration,MAP already works
Please tell me how to wire up
- The WBO2 (found several infos,but all suspicious)
- The coil ( a wasted spark unit) has a 4 pin connector
- Every injectors (the "injector common+" signal) must be directly connected to EC36pin23. 2 of the papers given with that device specify this. [shop text]. This is very easy (in fact obligatory) to test with DVM diode mode.
- AlphaN. The line of the VE table (RPM < hybrid_rpm_a) is selected according to the TPS position
- How to wire the crank VR?
- VR has no supply (such as "Sensor5V")
- the middle is usually the shield. Use your DVM, appr 500 Ohm is typical for VR.
- the VR sensor or the ECM is unlikely to be damaged if wired wrong
- if you are uncertain of VR+ and VR- (or if you experience strange errors, like RPM lost during certain conditions), apply InputTrigger/TriggerLog to be certain
Looks like the Astralogger has its own sensors (checked all inputs ,working without "original" ECU, and ECU sensors). I think that the camsync signal is used by this logger for RPM signal... Nice.
