Can someone please send me a e6x datalog from a good running FC.

I need a log of:

-Last trigger before home
-Home count
-trigger count

Much appreciated. Thanks.

Trigger before last home should always be 12. No less, no more. The other two are irrelevant and tell you nothing really.

Correct, and I understand this. 24 teeth for trigger, 2 for home, would be 12 teeth per home.

But today when I was reviewing my logs, I noticed some things. The wave for my home really looks weak compared to my trigger waves.

Also I noticed 8 trigger spikes per home spike. So I'd like to compare the data

The logger doesn't log fast enough to catch all the trigger pulses. That makes it irrelevant. That doesn't mean the ECU isn't seeing them. Just means you're not catching them with the logger. Trigger at last home is the only value that you should concern yourself with.

Can you look at that data log I posted from this thread?

Look at the home signal on the line graph.

It's barely anything, just a little lump.

This doesn't look right compared to my trigger spikes.

Should the home signal be a large spike like the trigger signals?

Forget the trigger and home counters. Like I said, the logger won't log them accurately, so just don't even bother logging them. You watch trigger at last home and rpm. If there are no radical spikes or dips in the rpm trace and the trigger at last home is always 12, there is not a trigger issue.

There's nothing showing up on the line graph for trigger before last home, yet there are definitely values showing up when I open the file in an excel spreadsheet.

The early graphing function of the E6X software sucks. Using excel is much better.

I remember looking over your datalogs and not seeing anything stick out. Are you still using the zero throttle map? I suspect this may be your issue. Any time I've had a thought about using it or someone has brought a car in with it enabled, it's caused more issues than it ever solved. I'm wondering if the spot at 2500 when free revving is where the ECU transitions off the zero throttle map and into the base fuel map. If the zero throttle map has plenty of fuel but the base fuel map doesn't, you get a lean bog.

Zero throttle maps been disabled.
