Wanted to know everyone's experience with mr12 and if anyone tuned for it or just running it. Most threads ive seen on this are on s1000rr and they claim 5-8 hp bump with no tuning and stock fuel mapping.
What if he is already running rich?not sure where you read no tuning required. mr12 is a HIGHLY OXYGENATED race fuel. without added fuel in the map, it may bump hp slightly but, you will not receive the gains estimated by VP without a richer map. you will need approx. 10-12% or more, fuel in the map to see the gains on the dyno, due to the added oxygen in the fuel. without the richer fuel map, you may run WAAAAAAY TOO LEAN, and cause damage.

Can you clue me into throttle position tune? are you referring to the ETV map?mr12 is a big power adder tuned out. my 04 went on the dyno with mr12 added at 174, tuned to 188, the 07 was tuned on pump at 180, extending rev limit and mr12 gave 193. bike will rip thru powerband on mr12. i used to drive 5.5 hrs one way to have my bikes tuned by a certain tuner. going fast is not a matter of convinience, matter of commitment. one tune, one time, lasts forever. many consider mr12 expensive yet i see them spend much more throwing ineffective parts and mods at thier bikes as my buddy with the 14r was doing. $300 tune and cost of a can of mr12 for about 15 hp is dirt cheap. i go thru 3-4 cans a season, not that expensive to go fast. that gen 5 will really respond to this fuel with a throttle position tune instead of just a top end tune so low/midrange gains are maximized also.
Only thing I would add is I have read you shouldn't leave mr12 to sit i your tank very long. Some people drain thier tanks after track days or flush with pump gas. Not sure if that is necessary, but I have read that. OP, what are your plans for your bike with mr12?
Wanted to set the mr12 tune to my M mode would be easier for men to remember. I would be doing some track days and lot of my friends do highway runs. Here in el paso we have str8 roads for miles especially when heading out to the desert. It would give me an edge. I wouldn't store it in the tank.Only thing I would add is I have read you shouldn't leave mr12 to sit i your tank very long. Some people drain thier tanks after track days or flush with pump gas.
