injectors ar connected as fully sequential.

car setup:
-primary trigger vr 60-2 stock alfa
-alfa v6 fire order: 1,4,2,5,3,6
-injectors bosch-702 cca 186cc?
-engine alfa 164-v6 turbo garret t25 1996ccm 8:1

According to the first picture and firing order.
your h[0] table should be.
32
4
16
2
8
1
64
128

For the injector settings
0
504
4080
640

100
25.5ms

1
5..0
Alternate

For Primary trigger settings

Falling
Multitooth
Disabled
Disabled
N-2
Normal

TDC after trigger tooth, this you have to check. likely 70-90 for a Bosch 60-2 wheel
Number of teeth. 60
Trigger tooth 3
Next Trigger tooth 20
Crank min 2224

i found out that :

"Trigger gap centre is 90 degrees BTDC on all the Alfa V6 motors I've played with so far."

is that it?

Thanks alot!

That would be it, but you need to confirm that with a timing light and your injectors unhooked.
while looking at your TDC mark where that is on your engine.
Post up more of your screenshots if you are having further problems

Are you sure about EDGE-FALLING , becuse here it says : When using a VR sensor the ECU must be configured to trigger on the rising edge of a tooth.

?

Thanks!

If you take a look at a VR sinus wave you can see that the signal crosses 0v at a long period and that may trigger the ecu
over a large range, tricking the ecu in actually thinking that the crank is elsewhere.



check out this picture,
See how sharp the falling edge is and long the rising edge is?
the ecu triggers when the signal passes 0v.,
That´s why normally falling edge is used.
I will never use rising edge with a VR sensor.

That´s cam timing.
And since vems doesn´t support fully sequential with adjustable injection start or end timing it´s of no use.
