Stupid PC-V Question

[Barry]

Hi - PC-V, flies out, autotune, full Area P, filter...  I have a FuelMoto map.  With PC-V do you have to "accept all trims" periodically?  I have had the bike a year, and just accepted all trims for the 2nd time.  No mods since I got it.

As I understand it, the more you accept trims, each time the trim should be smaller, per cell in the spreadsheet, yes?  Finally, at some point, you have no / minimal trims to accept?

Not sure I'm saying this right. 

Thank you....

It's the term for the compensation returned by the auto-tune.  As I understand it, the auto tune makes adjustments to the map on the fly, and provides these adjustments as 'trims' that you can commit to the base map as the default going forward.

Yes, you have the idea sir.

Though I wouldn't let it make any giant changes (anything more than 10% at a time), and it is almost impossible to get it to read zero's.... it will always move up or down a little bit. If you can get it to read in the single digits in every trim cell, then it should be good enough.

As a side note, I found something interesting when I was playing with mine.... The autotune does a **** poor job of mapping the bike in the 5%-15% throttle range at 1250-2250 RPM (it made my bike WAAAAAAY lean in two spots and the bike would stumble). I ended up just tuning it by looking at the AFR's and entering values manually 'till I got it where I wanted it. It may not apply to ya'll because my set-up is so, uhm, 'different', but I figured I would mention it.

Cheers
