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.


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.
Testing the visual trigger program. It’s the best that is happened to vemstune it´s simply too cool and will be a great help to all installers.

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

Config http://www.vems.hu/files/MembersPage/PeterJensen/volvo_t5/Volvo_5t_1175_marcell.vemscfg

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
