Launch control
Just like for the gasoline switch, pull an mcp3208 analog input to ground.
See EC18pin12,6,16 mcp3208 analog inputs in WebShop ECU specs, all are available in your case.
Measure if they are pulled up to +5V internally
- mcp3208ch6 and mcp3208ch7 inputs might be pulled to +5V via 2k7 internally depending on how you requested. If so, no need for external pullup resistor in the harness
- in any case, be very careful: pull to +5V gently, or to ground with a switch. These inputs are not protected agains +12V ! +12V on mcp3208 input would ruin the controller.

Review (check hints on these pages)
- 1.1.27 will NOT work properly with 4-1 (only 12-1 or more tooth supported with missing tooth setup because of tooth_wheel_twidth2 semantics).
- tested with 1.1.27 : despite the inabilitz to set toothwidth properly, the spark timing was perfect without ALS (because it is always timed from trigger tooth). However dwell timing at higher RPM means the toothwidth must be set properly, so we will apply some mod to 1.1.29 so trigger_tooth=F1..FF has special meaning:
- FF=720/1=720 crankdeg
- FE=720/2=360 crankdeg
- FD=720/3=240 crankdeg
- FC=720/4=180 crankdeg will be used for tooth_wheel_twidth2
- FB=720/5=144 crankdeg
- FA=720/6=120 crankdeg
- F9=720/7=.... crankdeg irrelevant
- F8=720/8=90 crankdeg will be used for tooth_wheel_twidth1
Please allow some time for this mod: the regression-test host had HD failure, some time needed to recover (install some software on new HD).
- 1.0.73 should work, is the only choice for now. Are you sure you tested with 1.0.73 ?
