No AFR and Unexplained Timing Advance

[kenjfox]

Trying to get my new MS3X install to idle on Miata BP4W. Seems I have no AFR- the gauge doesn't move from 7 or 8 while running, and the log is showing a tiny number. The Innovate gauge shows the 7.8ish number as well. Also, the engine is hunting severely- the engine almost stalls out, then the advance shoots way up to mid 30's, or maybe vice versa. I have open circuit on the idle control, so am not expecting the ignition to advance so much. Am very new to this, so could be something obvious. When I look at the ignition table, I don't see how the advance could go up that high. At this point, I'm looking for 2 things:

1. Anyone have issues or pointers with configuring an LC2 with MS3? I double checked the wiring and all looks correct. How to troubleshoot?
2. Could the AFR explain what I'm experiencing? If not- where else should I be looking? Are there better log fields to choose than the default?

Thanks,

Ken

I'd appreciate some guidance on troubleshooting the advance issue.

Post a log as native MSL, maybe you will get more replies. Some of us don't bother with anything other than MSQ and MSL.

The log is native msl, just zipped due to size restrictions.

I would first connect to the LC2 with LogWorks and see if the reading is equally high there. If so, I'd pull a lot of fuel out with the VE table.

As for the timing, TunerStudio has a screen to display all your timing calculations at the bottom of the Ignition Set-Up. Check that to see if a stray correction table is giving you too much timing.

Okay thanks Matt.

I looked at your advance issue, its following your table. You have high advance numbers at low MAP and mid rpm, which is normal. When your motor is running 2500-3000 rpm with no load the vacuum is high and the advance matches your table.
