Fun with Cipher

Just got my UpRev cable and played around with Cipher logging today. Took a WOT section and graphed it in excel. In order to get everything to overlay with the AFR range, I had to use some scaling factors with are shown in the legend.

A couple of things jump out at me:
1. Looks like I'm running a bit rich (<12) above 6500 rpm.
2. Throttle position lags Accelerator pedal position in first WOT section but not in the second WOT section.
3. Not sure what to make of the Ign Timing spikes prior to each WOT section.
4. Looks like Ign Timing is being pulled between 5000 to 6600 rpm.

Not really looking for any in depth analysis (but any comments are welcome), just wanted to share my awesome excel graphing skills.

yea, sounds like the stock tune lol.

if you look at the target AFR's, you will see that it shoots for 11.9 at high load.

Played around with Cipher more today and logged some VVEL parameters.

Interesting to see a possible correlation between ign timing and VVEL timing (no idea what VVEL timing is at the moment).

any chance you logged oil temps vs IGN timing.

not on the runs i graphed above. on an earlier run under similar conditions, oil temp was 97C max so it shouldn't be a factor (though i'll add oil temp to any future runs just in case).
