Current problem is premature rev limiter engagement at 6500 rpm instead of whatever max setting is. Not using soft rev limiter, min_crank_per set to 768 (9700rpm). I need more than 6500 rpm!
Maybe related to rev limit malfunctioning:
Realized that crank trigger settings were off quite a bit. tdc_after_trigger is only 30 degrees instead of the recommended 60. trigger_tooth is currently set to 7. Next test session I will change trigger_tooth to 4 and increase tdc_after_trigger to 60, then fine tune with strobing timing light. This is all after I fix the burst coolant hose of course =/

Made above changes to settings. Engine started and revved okay, but I didn't have a chance to drive it because of the coolant hose. A new hose will be ordered this week. No hurry since racing season is over.

My Genboard and LCD display:
Future Plans:
- Add relay and switching gear to properly set up launch and shift control.
- Add EGT sensor and hardware if necessary.
- Change connector on endplate for common DB9 cable fitment.
- Change over to standard GM IAT sensor for more accurate readings.
- I'm sure I'll find something else to add here.
Notes:
While browsing the net I came upon this thread about someone using 034EFI on their turbo VR6 VW Golf. The 034EFI setup looks very nice. The thread is located at: http://forums.vwvortex.com/zerothread?id=2470106&page=6
An AMP round mil-spec connector option would be nice for Genboard.
