I recently bought a 2019 RK with a 107 M8.
I don't want to void the warranty with an aftermarket tuner. I have no plans to do any engine mods. (I have other bikes to hot rod.)
I thought about getting the SE tuner and flashing the stage 1 tune onto the stock bike.
1 - A little more fuel to partially solve the lean stock map?
2 - The SE 950 RPM idle would be easier to deal with in stop+go traffic versus the stock 850 RPM.
3 - The tuner won't void the warranty.
What do you think? (PS - the cost for the SE tuner isn't a big deal to me.)
Make sure the selling dealer documents the Street Tuner on your SWR, so there's no possible warranty issue.
As far as adjustments, the SE unit is very limited. No AFR adjustment, minimal VE & timing adjustment, and I do not see where there is any idle speed adjustment, so where ever they set it, is what you get.
We do a lot of SE tuners on the M8s......its all you have to chose from....even a stage 1 map is lean is spots and can not be fixed due to the peramaters they have imposed ....adding any aftermarker pips will make the tune all but useless so stay away from that......there is one way to help low end off throttle issues .....but few if any know about it lol

Will the (small) additional fuel make a any difference on a totally stock bike?

OK, so I'll bite, Off throttle issues? haven't had any while tuning so apparently I must already know a secret I don't know about, lol
The stock 850 RPM idle tends to hunt +- 150 RPM, so sometimes when you take off the bike stumbles a bit.
The SE maps raise the idle to 950 and it is very stable.
FWIW, my clutch switch is fine.
I have no way of viewing the changes from the stock calibration to the SE stage 1 calibration but I suspect they are not very much different.
