Project VW Passat VR6
- Demo/Test Vehicle for VEMS V3.3
- VW VR6 6 cylinder engine
- Firing order 1-5-3-6-2-4
- Sequential fuel injection
- 60-2 VR crank trigger
- 1 Window hall cam trigger
- NTC temp sensors
- Standard TPS
- 2 OEM knock sensors
- High-Z injectors
- 3X double ended waste spark coil with ignitor
- 2 wire PWM Bosch Idle Valve (min/closed duty ~25%)
-2 wire, 8.2 Ohms (~1.5A)
TODO:
- Scope Idle valve,Tach signal,Injectors,Ignition
- Idle 100hz,4.4ms at idle (44%DC)
- Tach +10.8v, 66% DC "on", 3 tach signals per rev
- Injecion pulsewidth: 3.2ms warm
- Ignition: 4.8ms dwell at idle, 13.8vbatt
- Measure resistance curve of temp sensors
- Install and configure v3.3 board
Current Order:
- 1-wire interface: NO
- Ignition driver: 4+4
- Knock and EGT: Yes (2 knock,1 EGT)
- LCD and PS2: Yes
- MAP connection: Onboard 400 kpa)
- PowerFlyback: 30v bidr
- Primary_trigger: VR (60-2 wheel)
- Secondary_trigger: HALL (one window)
- Lower (than 510 Ohm) resistors for i259 logiclevel outputs for use with VAG 1.8T COPs
- OEM Bosch temp sensors (pullup needed?)
