I'd really have hoped so and lost an hour fooling with this assuming it was my fault. Probably still is, but seems a lot like it wasn't fixed.

Precisely. Got the car idling, and the timing marks on the pulley were extremely retarded, back about where the belt leaves the pulley. I would open the trigger wizard, adjust it (audible difference in idle), get the two marks to 10 and T (idle was stupid fast at this point), the instant I hit burn, there was an audible shift in the engine note and the marks were back at the belt departure point. The value I set in the trigger wizard would appear in my Trigger Angle/Offset field under Ignition Options. At various points in the day, I had anything from 35 to 80 in there and the marks on the pulley were in exactly the same spot (after a burn).

I eventually gave in and moved the damn CAS, but I was hoping for a software solution. I like to be able to fall back to the OE CPU as easily as possible.

I flashed this firmware version recently and I thought it went through OK. I looked at my mainController.ini file and the "signature" value is "MS2Extra Serial321 ", so I think the firmware is the version I stated...

Any ideas?


edit: 100% stock 94. And yes, I'm an idiot.

It's not fixed on my car, and yes that's exactly what happens. The car moves back out of sync by the same about, but at the 'new' trigger angle.

It's *****, but I live with it as once it's set, it's set. I just move the CAS instead.

if that's the case, that's what I'd do. But that's crazy, do not like.

Ha, I guess as long as this has been necro'd, is it worth upgrading my firmware? I can't seem to find a change log.

yes, for a start you'll remove a pretty nasty part throttle bug which causes a stumble.
