So I've bought my 2017 MT10 already mapped and it's obviously had the AIS disabled. My question is can this be re enabled via OBD as I want a bit of flames and pops.

I am fairly confident that the AIS is often deactivated in software when a re-flash is done, but that is far beyond the OBDB system. If the bike has not been reflashed then physically reconnecting the air hose to the AIS valves and reconnecting the solenoid to the wiring loom should get you there.

You can only reenable it via ECU flash. You can disconnect the hose from the valve if it's still in place and it'll pop and shoot flames like crazy. Kiss your exhaust valves and muffler packing goodbye though.
I did that on my old TL1000R for a few days - just left the pipes open to the air. The flames coming out of those twin pipes at night was nuts lol. Got annoying fast though.

Everyone says that it wrecks exhaust valves but then proceeds to quote car related resources which have flame tunes that result from timing adjustments in the combustion cylinder itself, not anything to do with the pair valve. I feel like the heat and flames from an AIS induced afterfire would be much less severe in terms of affects and I personally have never seen or heard anyone having valve issues on their bikes from pop and bang tunes. I recently decatted and tuned my bike with a local tuner and am trying to get a solid answer on whether or not it is actually bad. |

Plenty of people have made videos on why it's bad: Nate from 2WDW: www.facebook.com/watch/?v=428406102806619RevZilla video: RevZilla article: www.revzilla.com/common-tread/decel-pop-vs-backfires-whats-the-difference-and-does-it-matterZZ Performance (cars): Article on The Drive: www.thedrive.com/guides-and-gear/why-your-burble-tune-is-badSo the answer is yes, it's bad for your engine. it's not immediately bad, but it will cause damage over time. The whole reason for it with racing cars is turbo anti-lag. The explosions in the exhaust are meant to keep the turbo spooled up on decel so when you come out of the corner and mash the gas there's no (or very little) turbo lag. Those are racing engines that get torn down and inspected regularly as well. They also don't have catalytic converters to worry about destroying. People who do it on street cars (especially NA ones) are dumb. It wrecks cats and O2 sensors as well as your valves. Also those morons go popping down the street in front of my house waking my kids up all night long and making my dogs go crazy so fuck them. |

The Revzilla video confuses me a bit, cause they even say that with a full exhaust the pops and bangs are just more noticeable because of the removal of the cat and width of the pipes. Stock bikes still have the combustion occurring in the exhaust from the PAIR-introduced air it is just muffled much more significantly. Also 2WDW's video just comes across as a rant rather than anything very useful, although I agree the packing life is definitely reduced but when the pops and bangs happen on decel then how does that affect the AFR of what is happening in the combustion chamber? Vcyclenut has a video regarding the PAIR/AIS valve and pretty consistently says it doesn't hurt the engine in posts and emails I have exchanged with him. I am actually curious where the explosions/burning fuel and air occurs in the exhaust to see how close it gets to the exhaust valves in the engine. Again, the Drive's article mentions continued injection and severe mixture conditions off throttle with increased ignition timing, motorcycle decel pops and bangs have nothing to do with the combustion chamber or ignition timing. |

The stock exhaust does it but only at certain RPM ranges and it's not as bad as purposely making it happen. The stock system just burns off whatever little bit of unburnt fuel is in the exhaust that's leftover from incomplete combustion. The tunes purposely add more fuel to make bigger bangs. These bigger bangs create bigger shockwaves that go both directions and can cause damage. If you want to do it be my guest. There's a chance it could cause engine damage. There's a chance it might do nothing. |

I dunno the particulars on it, its above my knowledge and experience. But I went about a week or two from installing the aftermarket exhaust to getting the ECU flashed. The deacceleration pops from the exhaust were CRAZY. One of my friends riding behind me told me he could feel the shockwave in his bones. I just don't imagine at that intensity that it is good for the bike.
