Trigger setup for Alfa 60 deg V6
- firing sequence: 1 4 2 5 3 6 Even fire.
Acquired
- six logic level GM coils aquired
- VEMS v3.x with "auditrigger" feature (ordered.. you mean delivered by now, right?)
- Yes, its on the bench under power as I write.
Primary trigger
- 60-2 VR bosch wheel
- LM1815 detects the falling edge, but the processor sees the LM1815 output, so rising edge must be chosen in config (that is correct, primary_trigger bit0=1)
Did you check VR sensor polarity by the simple wrench-test (with DVM DC mode) or InputTrigger/TriggerLog ?
- I havent gotten that far yet. Im still bench testing by playing a wav file.
Secondary trigger - camsync
- Sequential ignition desired
- because of odd-fire, this engine needs camsync anyway
- well, turns out its even fire, the cam trigger will be derived from the cam mounted distributor. (some fab needed).
- are you sure that your camsync (position sender on the cam-shaft) is VR?
If you have the jumper in sectrig=VR position, than you can only trigger sectrig by VR pulse(s) on EC18-pin12 (connecting only a HALL-sensor to EC36-pin13 will NOT work by itself, although the HALL signal (pulling the EC36pin13 to GND) can be used to "mask" (==gate) the VR pulses as done in InputTrigger/AudiTrigger.
- OK, that clears up a big point of confusion. Ive been sending the wav file camsync signal to E36-13 but I have sectrig=VR. Ill change to EC18-12 for now. dont want to unclamp board yet.
Bench Testing Status
- Help! megatune shows rpm is !1893 +-2, should be 1740.
- rpmk 07D0 as show in config below
- m582_1740_200_20_1000_1000.wav file sent using audacity
- primary trigger EC36-27
- secondary trigger EC18-12
- no trigger errors but megatune shows ~1893 rpm.
- disabled secondary trigger, still get ~1893 rpm
- megatune shows rpm 1893 even with secondary trigger disabled. no trigger errors.
Questions
- ign_tdcdelay in megatune is specified as degrees (while half-deg internally). Some values in MegaTune are specified as 0-255, like trigger_tooth that does not have a unit of measure.
- current config values
Firmware and config
- firmware 1.0.38 \n
