Trigger setup for Audi S4, 5cyl Direct Fire engine
- Primary trigger is VR 60-2 multitooth
- Secondary trigger is a hall sensor, 10-20 Deg Slot fully adjustable (mockup distributor)
- What is the best way to configure this ?
- firmware modification, done in 1.0.24 (ready for testing)
- If we set another_trigger_tooth to 12 (5 per crankrot), and extend the h[2] table to 10 cells, and set dummy values every second cell, also for injectors, divider=02. I guess it would work?
- it would work, but with current stable firmware dwell-time would be limited at high RPM. In short, not a good solution.

- make sure you publish actual config (output of mcd) also, not just the intended config. If you mess up global.h (eg. using an old version, forget to update config.mtt file, whatever) this reveals the truth.

- if this is sure not captured with primary_trigger=coil-type config (which results in 24x higher RPM than actual, as in the log), than try http://www.vems.hu/files/Firmware/release/v3_firmware_1.0.25.zip we suspect a syntax thingie in 1.0.24 that could result in coil-type being activated
1.0.25

bad values
- another_trigger_tooth=0C (should be 0x18 = decimal 24) Just for no camsync /Emil
- crank_minper=A9 (should be lower, like 0x50 or decimal 80)
- ign_crank_advance=00 (I guess it will be adjusted later) Initial testing /Emil
