Not to mention others. I loaded the map for my stock SGS with Magnaflow Hitman mufflers.
SWEET! Now to begin auto tune.
I noticed that there is a toggle for speed limiter as well. Not sure I am going to test it, the limiter on mine was around 110 and I don't plan on testing that speed again much less higher but I am sure someone will enjoy it.
Glad you found the new maps! The OEM Speed limiter is set to a hair under 110, with it removed the bike can potentially do about 158. I've tested it out in the dyno with our Road King Special up to 155, as we added the feature in response to Fuelpak Pro tuners who are doing 5th gear pulls, and wanted to bikes to have more legs.
Nice info thanks. I had my stage 2 Heritage 114 up to 120mph. Is it possible my dealer disabled the limiter with the SE tuner or their computer? Or was my speedometer just way off??

It's likely off since I don't believe the the Pro Street Tuner allows for the disabling of those specific tables, but I could be wrong. The Speed Limiter switch we made essentially maxes out the allowable values for four fuel cutoff tables, effectively disabling them.

Cool! Thanks for the details. When warranty is up I know Ill be fixing this for sure.

If you're running with the SE Pro Street Tuner or a factory tuning map, 120mph is not possible on any M8 with factory ratio gearing. SE P/S Tuner limits the M8 engine to a max of 107mph or an RPM max of 5800rpms, whichever it hits first. That's why on a dyno it may appear that the rpm limit is 5400rpms if the speed has reached 107mph. Its worth noting that the max speed will vary slightly based on MY and bike model by 1 or 2mphs. I have also seen some reports of SE Pro Street tune rpm limits lower than 5800.
The only way to disable the speed and rpm limiters on an M8 is with an aftermarket tuner.

What’s strange about my experience is I’ve hit that speed limiter a few times on my 114 RKS, but never on my stage 2 Heritage 114...and I’d swear I’ve gone much faster/harder on the Heritage than I’ve ever gotten to on the RKS. I believebthrr Ed stage 1 and 2 maps bump the rev limiter up to 6400 range. It’s possible the smoothness of the RKS makes the speed feel more deceptive, but I’m also basing it on relative traffic speed and passing objects on my daily commute. I’d be surprised if it’s purely perception, but I will try to confirm just for my own curiosity sake at least.
Maybe my limiter just isn’t working properly? It’d be fun to have a defect that worked in our favor lol.

Definitely not 6400rpm limiter with the SE P/S tuner. The rpm limiter is built into the tune map and takes away fuel and advance when the limit is reached. The rev limit has not been adjustable in the SE P/S tuner since 2017.
6400 would be a "too high" rev limiter setting with most upgrade kits available on the market using an aftermarket tuner. Most higher performance M8 engines typically have a 6250 or 6300 rev limiter setting. You're starting to look for trouble banging up against a 6400 rpm limiter on a typical M8 engine.

Interesting but I cant think of any reason on earth why I would ride a bike that fast. But that is just me. If the new maps give better normal speed response Im interested. Sent you an PM about that.
