Needed trigger help ASAP
Car Bmw 60-2 hall sensor on the crank.
Getting trigger errors at 3000 rpm´s then mounted 9 k ohm to r30 then getting errors at 6000 rpm´s
Board is setup to read hall.
We usually use stronger, 2k7 pullup with HALL input (that's what is used in pre-assembled)
Anny hint to make this hall trigger working??

Volvo 5 cyl turbo 1999
When setting up this car I ran into problems.
Firmware is 1.1.75 as requested
Crank 60-2
Cam 180 degrees = high next 180 degrees = low
the test result is based on bench testing because I think there may be something wrong with the crank trigger wheel, it seams that I louse a negative signal somewhere maybe a ion fragment but I will confirm later.
The car cranks at 161 VT rpm´s so I set the signal generator (jimstrim) to 161 rpm.
At 161 rpm I get the cync getting on and off. Trig tooth 5 and 60 sensor degrees. If I type 63 degrees it´s working correct.
The strengths part is if I set crank/after start switching point to 99 (norm 300) the problem are gone
What I seen Trig tooth 5 and 60 sensor degrees crank/after start switching point to 300 rpm.
100-130 = good
131-173 = bad
174 – and up is good

- Do you also have vemslog of the behavior ?
- do you see RPM spike when the problem happens ?
- [www.vems.hu/download/v3/firmware/experimental/ 1.1.79] has low-RPM cranking RPM-calc fix: ign+inj actuation goes below 120 RPM (down to 30 RPM and below with some triggers, eg. 60-2), when RPM shows constant 100 RPM (not the precise RPM).

New strategy:
Only pre_trigger used
Firing order 1-5-3-6-2-4
Ignition wiring:
cyl. 1-6 to ec 36 pin 24,10
cyl. 5-2 to ec 36 pin 34,36
cyl. 3-4 to ec 36 pin 35,33
So firing this way h2 vemstune
0 ign out 6+7 ec 36 pin 24, 10
1 ign out 2+3 ec 36 pin 34, 36
2 ign out 0+1 ec 36 pin 33, 35
Injector wiring:
inj 1 cyl 1 to output 1 pin 7
inj 2 cyl 2 to output 2 pin 19
inj 3 cyl 3 to output 3 pin 8
inj 4 cyl 4 to output 4 pin 20
inj 5 cyl 5 to output 5 pin 9
inj 6 cyl 6 to output 6 pin 18
So inj firing order is: (maybe this have to be moved two places)
norm 1-5-3-6-2-4
to 4-1-5-3-6-2
