Please help.

I have problem that the trigger is to close to TDC. If I am able to trigger on falling edge I think that the trigger pos. will change 60 deg.

Q: What is the value of tdc after the trigger now (calibrated) ?

Why do it not show RPM?

See log files:

Thanks alot for the help.

Q: Why is the trigger not working ?

A: Your configuration shows you have configured your ecu for 12+1, your scope shots clearly show the actual trigger signal is 6+1. Secondly in shots falling-falling, falling-rising there might be a race condition between primary and secondary trigger, rising-rising will give best results. So i short, please update configuration using 'trigger settings visual', # of teeth in full engine cycle = 6, first trigger tooth = 0 (no other choice on a 6 cyl with 6 teeth in cam cycle wheel) and use the recommended reference tooth table. - DB

I have this BMW M62B44 engine.


Can I run it with the orginal CAM sensor that has 4 cam signals ? Yes.

Or should I remove 3 of the cams.
