I wish I'd thought about the 36-2 wheel when I was doing the timing belt. I assume since the Fluidampr is using the OEM trigger wheel, that the OEM version of the FM wheel is what I'm looking for?

Is it safe to also assume the failing cam sensor is my problem and I don't need to start poking around under the dash checking wiring?

Thanks much,
Yep, get the OEM style. The FM OEM style looks the same as the SuperMiata that works with OEM and Fluidampr. And yes, the cam sensor is your problem.

Nice catch @Rrrracer !

Gents,

I'm at Summit Point. I installed a new cam sensor. I seemed to have zero problems today. HOWEVER, take a look at the log at 65.252 seconds--"MS3 Going Offline". There was no indication of anything wrong. No loss of sync.

Thanks,

You come up with all the fun and interesting stuff. It also did it again at ~291 sec.

How did you see this offline message and how are you taking these logs? Internal SD card logging is disabled in your tune, but the log posted is in .msl format, and I doubt you have a laptop strapped in the passenger floorboard lol.

If the car did not stall and your logging device just stopped and went offline, a loose/bad cable between the MS3 and your device is most likely the culprit.

I'm using Shadow Dash and an old Samsung Galaxy Tablet to record the logs. I view the logs later on my laptop.

It is interesting you mention it might be the tablet's or tablet connection's fault. I recently purchased a new USB OTG adapter...

It's a bit difficult to interpret from the log, because it looks like the car just shuts down and you restart immediately, but I think the clues are in the Time and Seconds Logged fields. As they say, Time keeps marching on... but is not accounted for in the logs while Shadow Dash has checked out. If the car had stalled and you cranked it right away, the gap would not be there.

Still trying to get my brain around this.

I did have a couple of things that I saw with my own eyes--the apparent loss of all electrical power in the first log, and the battery light coming on in the second log. Logs also show loss of sync events, rpm dropping to zero, and "MS3 Going Offline", but I never felt anything wrong.

Should I assume I have more than one issue? I have replaced the cam sensor, and I ran my full size battery at Summit Point. The car seemed fine, but the log shows gremlins.

Thanks,

I think it's a connectivity issue between the MS and the logging device, especially if the car ran well without issue.
