basic question on sequence of events

[16Victor]

We know that the ignition sequence begins at TDC_after_trigger (and is then modified by the spark advance value).

Does injection start at TDC_after_trigger also, or at the trigger?

We have a 60-2 wheel on a V8.  Firmware is 1.0.73.

TDC after trigger is 58deg.
Trigger tooth is 0
Next Trigger Tooth is 15

Need to verify when the injection events happen to be sure to know we're squirting into a closed valve.

In this thread http://195.159.109.134/vemsuk/forum/index.php/topic,614.15.html, Rob mentions it starts on the trigger tooth...sorry to second guess but I need to be sure.

Thanks,

Ron

It injects on the trigger tooth.
