Title: Final Calibration Tts
Post by: Mag19 on April 26, 2021, 02:17:36 PM
I have a question with the final calibration that maybe someone can advise me on. Thanks. I've done some data runs and was working on a prior tune and was tweaking some. I was wondering if anyone would recommend to leave any of the cells in the main lambda table in closed loop with the final tune calibrated and in place. I know some like to leave some cells closed and didn't know which way to go. Thanks again.

I leave all cruising/lo load cells in closed loop, unless the pipe/cam combo has reversion issues in a specific area/section, I'll set that section to open loop as well.  No issues with mileage, and less drama with a tank of iffy fuel.

Ok thanks for that info. I thought it made sense to keep some of the cells in closed loop. Is the pic typical of what maybe what you leave closed?

Looks good. If I have reversion issues, I'll leave the idle area (1500 and lower) open loop.

Great thanks again. First thing I noticed when running it in closed loop like this as I was gathering data, bike improved greatly with power and response. I have a few more runs to make then I'll lock it in and configure it as in the picture.  Appreciate it
