So back to my original question- what is the "Set Lambda" logged data and why would it differ from the corresponding AFR cell values for a given MAP / RPM.
Probably plusses+ and minuses- due to other settings IAC steps PE DE Warm up etc..
Quick question. Ran first basic auto tune. Compared the VE tables between the Fuel Moto supplied map and the auto tune map. Most cells delta was only 2 to 4 with an occasional 7 here and there. Any reason to even run any more auto tune sessions? Thanks.
If you've mounted the PV on your handlebars, Watch the hit counts in those cells you don't usually
ride in to knock down those 7's. Are you using compare by % ?, 2-4 ain't bad but 1%-2% is better. But you could call it good. You had a good starting tune to work with.

Smokey I am just looking at the delta between the two maps. I did not select compare by %. Still learning this system. The bike was running great and it looks like the Fuel Moto map was damned close. Thanks.
So I had a tune I liked and just for fun I did the upgrade tune using new FW
It did not show any changes that I could tell when I compared the original to the one I updated, but the bike sure didnt seem to like it.
Not sure if it was just the day and the weather or if something actually changed that wasn't shown. Bike seemed to be running hotter and MPG was down.
Anyone else ever notice this when doing that?
All Software and FW was up to date when I did this.

Did you save a backup copy of original (before update) Compare the two to see what changed. Updates usually just add new items/folders in the tune tree that were there anyway but just not available.

Did you reset the trims?? If yes it might explain why the bike ran 'differently'. Once reset, the bike has to relearn the fuel and idle trims.
