Stage 2 - control ignition besides fuel
News - 2005.07.13
After all the car is running without motronic. GOAL! :)
/Motronic is still in place, but now only connected to idle solenoid - hopefully not for long/
Finally inj and ign is fine. Had some difficulties with trigger, first we suspected signal-sharing problems with motronic (series capacitor) but later realized that R181 (100..180k at LM1815 pin7) resistor was absent in factory v3.3 (first 30 boards. Only 2 boards were shipped without R181, emails were sent (to you too)). This caused trigger errors in higher rpm range and was depending on heat or something related to running time. After correcting that, engine was running fine.
Still has some knock (by ear), but ignition map is a freehand sketch yet. Waiting for dyno now.
Next attempt I'm going to control ignition too. -There's hardly any advantage of staying with motronic. GenBoard is ready for drive my ignition.
Factory coil and mechanical distributor is OK for the first time. When it's possible I'm going to wasted spark packs. (There's no room for COP)
I need to know 60-2 wheel's trigger position relative to TDC. Moved this section to MembersPage/GergelyLezsak/Trigger
Some additional tasks:
- Control Idle solenoid - MembersPage/GergelyLezsak/IdleControl
- Control tachometer
- Wire-in fuel-pump relay
- Control fuel consumption gauge (?)
- Boost control solenoid
Suggestions...
