The YEC ECU is cool but you lose so much of the street things. I have been talking with Jett Tuning over the past few days and getting more detailed info from them. The basics are covered here and on their website. On the 09 R1, there are three soft spots (5k, 9k and 12k) and Jett removes ALL the restrictions. Jett also alters the idle, throttle response and engine breaking. These things will improve all around performance and feel on the bike. Yes you should tune with a PC to get the best results but the Jett Tuning offering will have gains also. A YEC ECU is tunable (if you have the skill, time and equipment) but for $550 plus shipping, you can have someone that has already done all the experimentation and R&D. Then tune the PC at a dyno. This will save hours/days of work. When I spoke to Mr. Ethell, he said someone was posting their results soon so we will see what type of results to expect. The peak HP number is not the end-all-be-all in this instance but the all around improvements to the character of the bike IMHO.
....sounds like my next mod!!! Friends at AF1 Racing have a Factory Pro Dyno and said the 09 they tuned was ridiculous. They hated the restrictions, glad to hear bout the fix, thkx.......now I just need a job and it'll be a done deal
Not sure what all the fuss is about tuning a yec ecu. Takes me less time and is easier than a powercommander. Very simple interface. In fact the map is much lower resolution than a powercommander.
Now you're just being mean. Imagine if most of the "tuners":dundun: in this country lost their tuning-link and had to actually know where and why to make a change. Chaos!:crash
Hahahaha, then imagine us poor saps that don't 'deserve' the tuning link despite purchasing a PCIII and their datalogging wideband, who have to tune a dual injector bike, by hand, cell by cell, using excel to crunch #'s and intuition to determine how much of the duty cycle the primary injector is supplying!
I'm with Tim. Many comment that they like the "finer" resolution that the PC offers. I like to let the computer interpolate for me. But I think the truth was hit by ffaspector.
I don't get the fuss either. The yec is very similar to a powercommander in the way the mapping works just a lower resolution. I have the reflashed version of the yec ecu. Its great. I'm waiting to get it to my tuner still. He is racing through the 15th. The following weekend I should have it to him. I will post results afterwards.
Thanks for that Dyst, I"m about to pull the trigger on the YEC Reflash.
I've seen some Dyno baselines using Stock US, Stock Euro and Base Superstock YEC. There is definitely potential. When I saw the Stock Euro, I just about shat myself, the US bikes are getting shafted by the man!
I know what you mean.Never heard from any euro R1 owner complains about power ... neither about top-end.we got pretty much the same rwhp of the other liter bikes, even some hp more than gsx-r .pretty much the same power figure of the blade (161-163 rwhp) but with an healty 5/10 hp more till 8000 rpm over anything....and even some peak of 15 rwhp more than the beemer till 11000 rpm. my 09 puts on the ground exactly the same rwhp of my 07 when it was stock ... but with a lot more torque and 10 hp more flat till 7000 rpm, and you feel it immediately.
Does anyone have a good map for a yec flashed ecu? I will pay for a good map from someone.
