Trigger of a 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.
- Not really, the setup is not complete!
- We usually use stronger, 2k7 pullup with HALL input (that's what is used in pre-assembled)
- Find the HALL section on GenBoard/Manual/InputTriggerHardWare
Volvo 5 cyl turbo 1999
- Car started using 1.1.79. Only if I crank long time >6 sec it louse sync we can live with that.
Great work guys
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).
We tested with the following config (almost yours, just the outputs are different for test and the rpm limits to test very high RPM) on FW 1.1.79
It works fine from 80 RPM, but can be good smaller RPM too with real trigger.

Bmw E46 stretch six cyl.
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
