1981 Volvo 242 DL
The car is put together with mainly fabric new parts my dad had lying around in his workshop from his days tuning old Volvo's.
- B21ET Turbo engine w/Mitsubishi TD04HL16-T turbo.
- Volvo 940 Turbo intake manifold with Bosch 337 cc/min Low-Z injectors and Volvo 850 TPS.
- Custom made triggerwheel with Honeywell 1GT101 same as [this car]
- Singe coil and distributor ignition, no cam sensor.
- VEMS v3.3 firmware 1.0.38.
Trigger hits approx 65-70° after 0°.
Trigger should give signal ~60 degrees _before_ tdc /Emil
Update 2006-11-17
The car runs well with standalone ignition unit (Lumenition).
When using VEMS ignition, I cant get the ignition over 0° while cranking.
If I set "TDC after the trigger" lower than "2" my timinglight stops blinking. I tried 5-10-15 and 20 on "Priming, Cranking, Afterstart" - "Cranking advance" and still I get 0° on the timinglight.
Could this be firmware related? (1.0.38)
MSQ file [here]
A: TDC after the trigger should be 65-70 if the trigger is mounted properly. if you have it at 65-70 after the trigger, your setting should be 110-115 degrees.
Also make sure that ignition offset, under Extras , Advanced ALS is set to 0 degrees.
A setting of 2degrees TDC after the trigger will make it impossible to have advance above 2 degrees.
