Race ECU Installed

We installed a race ECU in my girl yesterday. The first thing I noticed was the sound difference of the higher idle. On the LCD, the clock is replaced by engine runtime, above that is a digital tachometer. Temp (in Celsius) replaces the speedometer. The fans still work, but the red bang light is lit when they are actuated. The higher idle speed heats her up more quickly at stops (air temp was in the mid 80?s); I just cut her off when I stop now. My mechanic showed me that when she heats up and the fans kick in, that she will cool herself back down, but the RED light on my display fuels my paranoia. The higher idle is great. It eliminates that rough characteristic from clutch disengage thru pull-off; her throttle bodies remain open. She is a sexy beast. She is now the bike she was supposed to be! Somewhere in that ride, I had a Zen moment where I realized that there is no way Yamaha could have delivered to market the bike that she now is. For one, the more urgent idle would prevent her from passing emissions. Yamaha gave us what they could. installation side note: the oddly phrased instructions were obviously written in Japanese then translated to English, they contain photos of the bike with components in locations which have since changed, they are vague

Did you change the harness and all? Where did you get the ECU from?

Did you change the harness and all? Where did you get the ECU from? No, I did not go to the race harness. http://works.gravesport.com

The YEC documentation states that the ECU is intended for use with an Akrapovic muffler. The airbox which is pictured is not the US version. I assume that they are not running a cat.

...The YEC ecu will have it higher and doesn't work too well with the stock velocity stacks... Which velocity stacks is it designed for? ...the ecu is designed for more compression and other changes in the engine so the stock map it comes with might be off. I saw that the super bike mode had the 110 cam and 12.8+ compression. I?m only running the super stock mode. Aside from exhaust, and air-box/air-filter what changes are assumed? Do you have any documentation in addition to the CD? Thx

...Superstock will run higher compression than what the manual says, degreed cams and depending on organization more duration. Light portwork... Are you adjusting these specs in YMS?

I didn't think the fans worked with the standard harness.. its good to hear that they do!

I got no fans on my R6 :p. Do you have a copy of the software or can you take a picture of the cable that you use to connect to the KIT ECU

Do you have a copy of the software or can you take a picture of the cable that you use to connect to the KIT ECU Yes, I have a copy of the YMS software (let me know if this is what you want). I did not take any pictures of the install. As Diel11 pointed out in the "09 Motor work" thread, the race ECU is the same piece of hardware (same connections) with different software. The only variances are the weight-saving-race-harness (which I am not using) and the sub-harness which allows you to connect a PC (USB) into the harness to custom program the installed ECU via the YMS software.

I have one on my racebike right now, I am trying to figure out if I need to program my ecu at all? What features of the KIT ecu will you be using? I would like a copy if you can :)

...What features of the KIT ecu will you be using... I went with the race ECU just to unlock 4th, 5th, and 6th gear. I thought that I would be able to plug-n-play the race ECU in pre-programmed super stock mode. ...I am trying to figure out if I need to program my ecu at all... I am discovering that I will need to go into the YMS to check what values are in play (the specs provided in the documentation may not be what is programmed in the ECU). The fact that my fans work while diel11?s fans don?t and the inherent inequality of super stock bikes have me inclined to believe that the programming of race ECU's is not as standardized as that of an OEM ECU.

The ECU Sub-harness (part# 14B-F8610-70) is now available at works.gravesport.com

would thoes connectors work for the 06 R6 also? How does the pit limiter work or how does it get programmed

Mine never came on, and I didn't have the red light coming on either. I remember you mentioned that ok. I just got my 09 today, so hopefully can get the race ecu sometime in the not to distant future and try for myself :thumbup

DAMN! $152 for 4 wires and a connector. Yeah, and no kiss afterwards either...:whtfu:

Nice work ATL! Any plans to dyno it so you can see what gain in HP the race ECU got you? ...I had a Zen moment where I realized that there is no way Yamaha could have delivered to market the bike that she now is. For one, the more urgent idle would prevent her from passing emissions. Yamaha gave us what they could... I'm not sure how you can say state something like this as fact. How would the emssions be changed just because of a raised idle? There would be more emissions, but the exhaust gas composition shouldn't change much, if any. Maybe I'm missing something.

Maybe I'm missing something. yea they test the sound level at an rpm that is a percentage of what rpm the bike makes peak hp. so if the the ecu didnt cut back the throttle the power would continue to climb and they would test the sound level at a higher rpm causing it to fail noise emmisions.

I am still waiting on some parts. yea they test the sound level at an rpm that is a percentage of what rpm the bike makes peak hp. so if the the ecu didnt cut back the throttle the power would continue to climb and they would test the sound level at a higher rpm causing it to fail noise emmisions. :yesnod

Does the YEC ECU allow you to default into a selected mode? Like A-mode?

Brian, if I recall.. You lose the d-mode with the YEC ecu. I believe diel said it goes to a mode that's extremely responsive. I did my trackday in STD mode just to be safe. I think A-mode is a little TOO responsive. Forum member Shrike races his in STD mode as well.

Not entirely sure I want to do the YEC ECU, but it might make since if I decide to race next year. Hopefully I get a chance to see what the differences re first hand before I commit to this mod. I've read the entire 40 pages of Deil's 09 motor thread and still can't decipher exactly what teh gain is from de-restricting the TPS.

Is it true The ECU free's up around 10-15bhp in 4th 5th and 6th gears? I watched a video on youtube of the r1 on the dyno completely stock with just akra cans, but the maker of the video kept comentating that the ECU was holding back a lot of the r1's potential power in high revs, so i'm wondering if the new ECU free's up all that "hidden power"?

I am not big on dyno numbers so I never baselined her. I can say that it has made her into a different bike. The OEM ECU is a smog conscious generalist while the race ECU is all about the go fast. I no longer have a speedo to say how fast for sure, but the other guys were saying that they were 180+ between 7 and 10a of Road ATL and she had enough to take two positions bully-style. The race ECU is the #1 mod for 09's.

Thanks for the info, but is there any way you can bring the speedo back? I don't miss it. Getting rid of the speedo has been great for my riding. You can always mount a bicycle speedo (some go up to 200mph).

Thank you. I have some additional mods before I dyno. I am still waiting on some parts. :yesnod SO you lose A-mode with the YEC ECU? also keep me updated when you dyno your baby, dying to know how it turns out.

SO you lose A-mode with the YEC ECU? also keep me updated when you dyno your baby, dying to know how it turns out. I don't miss the modes. I feel that I need to learn total control of her full throttle. Once I get my Y-pipe and BMC, I will know if any additional mods will be needed (I'm mindful of Diel's wisdom on the stock stacks with the race ECU and the tunability provided by the PC5...this is getting expensive!). I can then look to fine tune (and dyno).
