interpret VEMS trigger log?

Postby nmerrill » Fri Feb 22, 2019 3:01 pm

Posted this over at the VEMS forum, but it seems rather sleepy there... here too actually, what's the deal with that?
Anyway, wondering if any one has insight...

Hello folks,
I've done initial testing on a new 60-2 VAG rear main seal trigger, with distributor Hall secondary.
I wonder if someone could educate me on the meaning some of the output?
Firmware 1.2.31
5 cylinder - using default 5 cyl 60-2 configlet settings, and initial setting of 72deg. TDC after Trigger.

Full triggerlog here:

What is the meaning of LESS PTRIG ? It appears to have the correct number of Ptrig teeth represented (58) in each case.

Also, am I correct in interpreting that when this error occurs, it interrupts the ign events, which is why there are only 4 indicated. The cycle starts over after the next secondary trigger, and is again interrupted by the error?

Thanks!
Nat

figured it out.
primary trigger settings Configlet for 5 cyl 60-2 sets trigger edge to rising as default - I failed to change trigger edge to falling for VAG 60-2 RMS trigger.
Now clean trigger log!

But, timing light shows cylinder 1 firing at cylinder 4.
Guess I need to alter the ignition outputs. I need to figure out the difference between rotate firing order, and shifting outputs...
