Say, Is there a way to tell if your bike has been flashed?

Flash will not affect your speed at a given RPM.
Sport vs. Touring mode will not affect your speed at a given RPM.

About the only way is to find someone else that knows for sure that theirs has/has not been flashed and compare. Mine is not, and I think it's perfect. Others think the throttle is too twitchy from the factory. A flash, apparently, takes the "twitchiness" out. But puting it in "T" also slows the twitchiness down a bit. Mine stays in "S". Favorite bike ever.

Easiest way is to check temperature cooling fan comes on. Stock is 221F, anywhere else and your bike has been flashed. Most tuners lower fan on/off temperaures in the interest of heat management. Secondary method is to pull the ECU and look for markings, other than OE on case.
Good luck!

I just took mine out for a 2nd shakedown, minus the windscreen and shock-sox (my old socks ziptied to the forks to catch leaks) and the thing rips. I though sportmode would add a little but it is properly quick. Its gonna be a fun machine!
Flashed or not, "S" or "T", horsepower will be the same. It's all about how quickly the throttle responds to your input. If I am in "T", and don't realize it, I will kill the motor trying to take off from a stop sign/light. In "S", it responds every bit as quick as I want it to. I think that's where the confusion might come from. In "S" things happen quickly which some see as increased HP. But yeah, she's a fun bike.
I think that when they flash an ECU, in most cases, they leave the injection circuit closed, "nullifying" the lambda probes. if this were the case, you should disconnect an oxygen sensor... if an error does not appear, the ecu would be flashed
I forgot to add: If you like the way it's running now, don't worry if it's flashed or not. Just keep enjoying it, 'cuz that's all that counts.
Bikes only get flashed to correct a perceived flaw.

My tuner left the sensors connected but switched them off in the ecu. Otherwise it would be constantly throwing up faults if you simply disconnect them on a 2017 bike. Maybe different on other models

70mph indicated is right at 4k rpms with how these bikes are setup gearing wise.
That seems way too low of RPMs for that speed. (flash wouldn't affect that) So, either the speedo is off or the tach is. Neither of which a precision instrument.
Yeah, that's real close to mine. (73 @ 4k)

As noted above the tune won’t affect RPM at speed as that’s mechanically determined by the fixed gear ratios. Because it’s a mechanical relationship, riding mode (S vs. T) won’t affect this either.

That is why I said that it would be a way to find out, when you buy a used motorcycle, if the ecu is flashed…..if you disconnect an oxygen sensor and a “check engine” does not appear…..the ecu is flashed….
The mechanical relationship between rpm and real speed (gps), a tuner will not change it. Probably what they are referring to is modifying the relationship between the signal pulses, and what the speedometer shows, to eliminate the error in the speedometer, and that it stops showing more and shows the closest thing to the gps

That’s not what I was saying.
If you disconnect the sensors and remove them it will throw up faults even on a flashed ecu. The trick is to leave them connected but switch off their data in the ecu. 2017 model

Anthony flashed my gen1. I disconnected the sensors to see what would happen. It barely would run. I’ve never seen a code on my dash.
Mine is flashed by Anthony and my fan comes on much sooner at 204F and shuts off at 195F. I don't know for sure on peoples flashed units but I do believe that flashing adds some hp or can. I have flashed my VW Touareg 3.0 TDI and it went from 240 HP to 305HP. My diesel truck with a Duramax with a light tune or flash gained 90 HP. So flashing can increase HP. With 1200 CC you won't get a lot but you can get more. Depends on what you ask for.
It is about electronics and Engine Control Units. How it controls. It is the same. Diesels are air heavy and gas is fuel heavy and different ways of combustion ignition but messing with an ECU can manipulate fuel, timing, etc. I will send an email to Anthony and see what he does and if he thinks HP changes.
