I don't have the first damn clue about all these newfangled bikes with all this electronic wizardry. However, from the little I've read, an ECU re flash will fix it, among other issues.

 

Is it possible to get the flash tune to Euro spec, or are there better maps available from U.S. vendors??

Thanks

 

Noise restrictions is the only thing is what mags are saying yamaha had to meet. There is a top speed limit but im not sure if thats just the usa

 

USA ECU has a different pinout from Euro, so you can't just swap them. I believe the only coding difference between the two, besides the immobilizer, is in the throttle by wire settings, which are quite different. USA model caps the throttle opening at 87% (IIRC) for noise abatement. Somebody posted the TBW tables in the motorcycle.com shootout thread.

Flash fixes this for USA models. That's the only fix.

 

The most interesting question is probably WHY Yamaha need to use different ECU's for US and Europe...? All of the competitors are obviously getting away with using the same ECU and thus the same performance all over the world. What did Yamaha do wrong when they need to remove ~ 20 hp from the US model...?

 

Yamaha hasn't done anything wrong!! These unlike other bikes are actual race engines made for the public!! The whole design was developed on a race only bike(M1).. Hence the Crossplane and everything else about it!! It was designed on a race track and put on a street after years of just track time.. I would be 100% sure that both euro and USA bikes make the worst emissions out of any other bike because on a track it doesn't matter what emissions they produce just sound levels. To make them legal they have to de-tune them like crazy ECU or what ever to pass regulations for each continent they are shipped too.. Have you ever been on a xplane with no cat? Strongest exhaust fumes out of any other bike. Period

 

Well everyone else has an immobilizer system and we dont. So thats probably the only real difference in the ecu. We have some idiotic laws. Im talking anyone can buy and ride any size bike they want and not wear a helmet but god forbid yamaha sells a bike 7 decibels louder

 

what about us Canadians? do we fall in the north america noise restriction / emission friendly hippy ecu? or do we have as advertised ecu lol

 

I would like to know this as well.

 

I sold a BMW to get the R1 and it had the best sounding exhaust of any factory bike I've ever had. It was louder and throatier then the R1 and apparently not an issue for them. The R1 exhaust is awful you almost have to replace it. I don't get why Yamaha would go that route.

 

I don't get why Yamaha would go that route.

That's exactly my point. How come some of the other manufacturers - with bigger displacement engines than the R1, with higher torque engines than the R1, with higher horsepower engines than the R1, with visibly smaller catalytic converters than the R1, with obviously louder exhaust systems than the R1 - still get away with selling the euro spec bike in US...? When Yamaha don't...?

This being related to the crossplane firing order is highly unlikely as this would affect a 90 degree twin and a 60 degree V4 as much or even more. So, what the heck is going on...? Is this simply a case of fishy italiano environmental lawyers versus honest japanese dito...?

So you don't really lose too much buying a U.S. version.

Basically, if you are going to flash your ECU, it does not matter. Possibly, the US bike is the easier starting point for a proper race bike build since it will save you the hassle removing the immobilizer.

 

So you don't really lose too much buying a U.S. version. I'm supposed to pick up my R1M on the 13th but a friend supposedly found a eu spec one for me overseas. Which saves me shipping my bike back with me, but it isn't guaranteed. He can't tell me before my expected pick up date for my bike in NY.

Based on what people are saying I think I'll just take the one I have waiting for me and eat the $2k for shipping

 

Canada has the euro-spec bike.
