Once I got my new pipes installed with the 18 mm bungs I rode very aggressive to try and populate as many cells as possible bringing the e motor up in the 4000-6000 RPM range and throttle position at 60 70 80% 90% 100% throttle.. I really wanted to load the motor to hopefully get the best tune for hard riding and it did..

So after exporting, saving and downloading that auto tune into the ECM I then did another auto tune.. I didn't ride as hard this time and was very surprised to see how this session had lowered my VE tables.. started to lean out my tune..

The thing I'm trying to show here is that the auto tune session is constantly changing the VE tables, So if you want a tune that will protect your motor with higher VE tables and better AFR's you will have to ride the same every time you do an auto tune session.. light to moderate riding will decrease the VE's as compared to riding hard..

So here's what I think should be done.. Do a hard ride to make sure your VE tables will be higher than say just a cruising tune.. This will be your base tune and should not be altered any more and store it into your ECM.. This way you'll always have the tune you need for hard riding.. The reason why I say this is because with wide band O2's are constantly monitoring AFR's.. It will still try to change injector pulse width based on throttle, set AFR's, map etc but you will still have the base map that won't go lean on you..

This is the way I'm starting to see it.. If anyone sees it differently please let me know.. Hope this helps..
