Genboard configuration
[tables.txt] and [config.txt] (Updated 2005-09-26)
Current problems:
- The ignition dont work too good.. cyl 1, 2 and 4 fire when cyl 1 and 4 is at BDC (2 at TDC, all at the same time) cyl 3 dont fire. Should i maybe put coil #1 and #4 on EC36-pin 35, and #2 and #3 on EC36-pin 33? and compile without IGN_DUALOUT? ORE, set up with cam-synk? fully seq, and Direct Fire??
- The injectors stay open, and I could measure 1.65 V over the injectors, they close when I turn the ECU off.
- The "false trigger counter" at LCD is counting up every revitation when cranking, maybe because of the strange 44-2 wheel?
