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.

Initial (not running yet) config and tables
Review (check hints on these pages)
- 1.0.73 could work, but advanced multitooth filter=enabled needed for low RPM (cranking)
- [firmware 1.1.29] seems to work with 4-1, the following config:
- could work with advanced multitooth filter=disabled (untested)
- tested with advanced multitooth filter=enabled , this requires proper settings for the
- normal tooth (eg 37..150%)
- and missing tooth relative range (eg 150..250%). The config that came from 60-2 had missing tooth relative range set to 200..375%, the 200% is clearly bad
- tooth_wheel_twidth1=68 (in MegaTune, width of normal tooth=104)
- tooth_wheel_twidth2=01 (in MegaTune, width of missing tooth=1)\n
