I have the Ktuner end user system, and I'm running into issues with my '13 Fit (Auto Tranny) changes to the fuel map are reset to stock. Is this a known issue with auto cars or is there any possible workaround or solution? I understand manual Fits work flawlessly but im not sure if anyone has done this with auto trans Fit...
A tune can't revert back to stock unless you've flashed it to stock. An ECU can only hold one set of settings at a time, which is whatever was flashed last. Since you don't like my answer for this you should try datalogging and review the differences to figure out what is actually going on. That's not it.
Perhaps I should say it's going into limp mode or something similar. All I know now is it leaves the dyno at 111whp and by the 3rd turn it is 94whp. Will try logging. I bought another car to build for the runoffs in the mean time so that is taking a lot of shop time. Will advise if I find something. Everyone seems to think it is a ground issue.
