2015 YAMAHA MT-09

Thanks for the advice. I shall do some research and see which option suits me best.

I was actually going after a 2014 Gixxer 750, too. Great price on that one I looked at.

But the 2015 model's colour scheme is way better while this newest one is significantly out of my budget. After all, I chose MT-09

 

That's fine if you want to pay somebody each time you make changes to the fueling or ignition timing, or you want to squeeze every bit of available power out of the bike.

A flashing interface for that specific bike will allow a lot more customisation - more than just fueling and ignition. You can adjust fan temp operation, speedo calibration (useful for when you change sprockets), engine braking, throttle response mapping, plus other things. Adjusting the throttle-by-wire is easy. You can play and adjust until you're content with the settings and it doesn't cost you each time you want to adjust it. Or you can find someone online who's already done it and download that throttle map. Fueling maps for most applications are also available and while they aren't perfect, it's easy to find something that will improve on the stock setup and work well for the bike. You should even be able to find a tuner who can work with the interface to create a map for your bike specifically. Makes more sense to me to flash the ECU than buying and installing an additional fuel controller, but I understand it's not for everyone

 

So is a Flash tune or a PC5 better in this instance? If both are tuned professionally?

 

I can't comment on what happened when you flashed your bike, but I've never had a problem flashing my R1. I made sure I had the right "canned" tune.

The other stuff might be secondary to you, but the OP specifically mentioned the throttle. Flashing allows direct control over that for each of the engine modes without having to change the fueling at all. You can keep one snatchy for when you want to feel like a racer, and smooth the others out if you want. Or smooth them all out. Lots of possibilities.

Also, I wonder whether the people who didn't notice the throttle snatchiness actually rode the bike in A mode.

 

Don't worry, the jerky throttle will only shit you when you are going slow, there is plenty of people watching and you are trying to look like you are a competent rider. Any other time and it won't cause you a problem.

 

WTF Double post again.

 

Flash tuning at home how do you know which part of the map that needs adjust or do you just guess until you think its right.
Using USA programs be very careful as a couple of our customer that went down that path ended up have to buy new ECU. US ECU are different and run Different wiring harnesses just a warning. One persons map is never going to be correct in another persons bike.

 

Just like a vasectomy.

 

Serious question, how long does a tune last for?

If a Dyno tune is customised to a bike based on the mods, weather conditions, fuel, how old the bike is, K's on the engine, etc etc. how long would it last?

Say a downloaded map gets you 85% (hypothetically), and a 'tuned' map on a dyno gets you 100%, how long will it be at 100% if its affected by a variety of factors? Would someone need to get it retuned every 6 months.

Also @Moto_Garage do you have the facilities to tune the standard Yamaha ECU fuel maps? If so, whats a ball park figure for both a baseline dyno run (to determine how messed up it is), and a dyno+tune.

Cheers,
JR

 

Most of the downloaded map that people install on their bike before they come in for a tune would be in the minus region [-10%] as they make less than a zero map. US mapping doesn't work here as we have different bikes and fuel standards.

How long do they last at least 30,000 k before wear on the engine is noticeable and a retune is needed.

Race bikes at the pointy end of the field we retune them every 2nd meeting and log data at the track every meeting . The type of oil you can use in an engine can change the tune we have used some oils that gave us an increase of 6hp on a CBR1000RR over normal full syn.

@John.R give us a call on Tuesday and we can sort you out and yes we can redo your standard ECU

 

I got the 15model MT09 fitted it with the full Akropovic pipe straight away, the jerky throttle is only a problem when going slow, A mode only used bit of throttle and presto no jerky throttle (concentrate on being smooth). As for the suspension wind up the preload on the front if you are finding it soft a lot easier than paying someone to fiddle with it - mine is as delivered & the only issue I have with it is it's compliance over bumps but I was used to top shelf white power suspension, can see ground clearance becoming an issue only 450kms & already touching

 

You must be leaning it hard...

 

Might even be worth pulling some preload out of it. My R1 was far too soft in the front but found it was a better comprimise to lose some braking through bottoming out the front to gain stability in corners. Do the MT-09's have 3 way adjustable front and rear?

 

Exactly what supamodel said - very basic suspension, but you get what ya pay for

 

ZX10 rear shock sorts out the rear, surely someone's replaced the fronts with something that doesn't cost a bucket?
