hello, I'm trying to start audi v8 engine (136 tooth on flywheel) with auditrigger divided by 2, using cam hall inverter.
trigger config :

I'm getting rpm readings, but I cant get spark.
sometimes spark shows for one time:

trigger log: http://www.sendspace.com/file/8g317n
so, can anybody help me?
is this tooth width problem?
you don't have 136 teeth after dividing.
What are you sec trigger sensor settings?

sec trigger
in 5 cyl audi trigger divided by 3 i get (135x2)/3 I get 90 tooth, next trigger tooth 18
in v8 divided by 2 i get 136 tooth next trigger tooth 17, or I'm calculating it wrong?
I want to run it sequential
imho yes.
next is 17, but number is 68(per one crank rotation).

yes, tried this number today, then I got spark but got many primary trigger errors too, so how my reference tooth table should look?

ref table are ok I think.
yes, ref table is good.
imho problem is that sec trigger isn't allways on 100% same position.
Try to change sec tigger to falling. Also play with LS-1 forgiven.

if I change that number, I got a configuration error, just ignore that? and when cranking it shows too many primary trigger is this like you said sec trigger position related?
so one more evening of testing :)
trigger log with to many primary trigger looks like that:

in newer vemstune it looks :

tried to enable special extrapulse trigger then I got spark.

but when I tried to strobe ignition with timing light spark has gone again when I changed tdc after the trigger value. changed value back, no spark :( is it posible that I need to play with first trigger tooth value and shift the ignition outputs in events?
maybe it is possible to use only 2 triggers for that car? 136 tooth on flywheel and 1 cam hall pulse?
something like this?

on your place i would put 60-2 trigger wheel somewhere in car.
If your trigger starts to work, it'll be very unaccurate. Problem is with timing belt.
Let start from beginning
1) divide by 2 gives 136. But it is probably too much for CPU. You can try it also later.
2) In final you still need dividable by 8 result. Seems there is just one option: divide by 17
Divider 17
It gives 16 teeth on wheel (not the best but for me seems it is second option after divider 2)
first trigger tooth 0 or 1
TDC after the trigger - keep in 45...70 range preferably by changing previous value. Exact value you can find with strobe light.
Next trigger tooth 2
Angular width 45deg
Ref tooth table
0
14
12
10
8
6
4
2
What else: you have to be sure about Hall signal occurs during every second TDC signal.

i Gints, thanks for the help. getting spark with yours settings when switched to older firmware from 1.1.97 :) battery died again, so we will try to start later ::)
