ECU recall with PAIR removed

[leclairk]

I will be taking my 06 into the dealer for the ECU recall and I did the Wynpro plates when I ripped out the PAIR system. Is the dealer going to hassel me about having that removed? I wouldn't think so but wanted to see what experiences other people have had.

Also, I searched and searched but could not find the answer. How bad is the "surging" that happens in high altitude? I'm doing a trip this summer with elevation up to 7000 feet and have never had the bike that high. I'm not sure I can get the ECU switched out in time for the trip. Is this going to be a problem? Surging when I'm just cruising is fine, I'm worried about surging in the twisties.

No.

The surging will most likely occur when you descend from higher

elevation. It doesn't have to be at high altitude, just a significant

change. For example, a 2,000 ft change may be enough.

The ECU compensate on the way up but doesn't recalibrate on

the way down.

When this occurs the engine will bog accelerating under load.

To reset the ECU just pull in the clutch, turn off the key, turn it back

on, release the clutch re-starting the engine and go on your merry way.

Repeat when necessary.

No to both.

BTW - My '06 never experienced the problem from sea level to 14k+ feet. IIRC and it's been a long time, the original ECU resampled the barometric pressure (MAP?) when the throttle was opened more than X (20?) percent. The replacement ECU reduced the throttle opening required for sampling.

Ride it and don't worry.

They aren't going to remove the fuel tank to replace the ecu. They will never know about the pair removal.

Escapefjrtist is correct. I live in Albuquerque @ 5115 feet in my driveway. I had ridden Southern CO, Sandia Crest, out to my parents, and across Northern NM before I ever got a recall notice. I think my house is the lowest of any of these and I never had an issue. My parents house is right around 6000ft, but from here to there, I lose probably 200 and then gain 2500 before settling back to their 6k and no issues. I was surprised when I was told of the recall.

The original ECU adjusted when the throttle was moved 1/4 turn. The new ECU reduces that to 1/8 turn. The rider has to be riding pretty lazily to not move the throttle 1/4 turn during massive elevation changes, but I did it just so it was done.

Chuck is correct about the ECU install. No need to get under the the tank for that change, and I'm assuming your bike is.out of warranty anyway. Not that dealers care. My dealer thinks my block-off plates are cool.

When I went to TN last year, riding the Cherohala Skyway on my bike the surging was horrible. Made the bike downright unpleasant to ride.Wish I'd had the recall done much sooner and that I'd done more research before the trip. I didn't know you could just shut off and restart the bike to get the ECU to readjust. Only took my local dealer a few days to get an ECU. I'd try to have it done first.

Cycling the ignition does reset it as it re-samples the pressure. I experienced the problem with mine before having the recall done. As previously stated, it doesn't take high altitude just a large change in altitude. The dealer first told me I didn't need to do the recall, because I don't experience high enough altitude for it to affect the bike! I told him it's a recall. Do it!

No.

Funny thang, on my 1st '07, I'd gone from sea level to over 7K ft, and didn't notice any surging, but after the ECU fix, the on/off throttle was much better on the bike.

I noticed it all the time on my 07. It is most noticeable when WFO transitioning from a higher elevation to a lower elevation. I always noticed it descending from Angeles Crest to Lower Big Tijunga. Very annoying for me at least. All is good with the new ECU. Even with the loosened throttle spring, new ECU, and PCV with smoothness map, I still have low speed on off throttle issues. It seems to hesitate for a split second and then go. Makes it hard to exit corners and apply a little throttle. The ECU is buried under the seat near the air filter. Must remove loads of plastic to get at it, but not the tank.

I haven't yet taken the time to do the ECU recall; however, the surging isn't too bad and I've had my bike from 0 to 14,240'. In my experience, the problem generally crops up sporadically and usually as you're rolling on the throttle coming out of a turn. A bit of WOT or key off/on solves the problem. It's really just an annoyance and in no way a showstopper. I'll probably get Ron Ayers to do the recall later this year while they do the wiring recall...which I haven't done yet either, lol (I have Roadrunner's fix installed).

Thanks for the tips guys. As always, this forum provides so much good information. I will try to get it done before the trip if it works but won't sweat it if I can't get it done. I called them Tue to have them order whatever recall parts were needed. They said they will run my vin and get back to me. Still had not heard anything on Thur so I called to follow up. They told me they are very busy and if I haven't heard from them by Sat give them a call. Now I know why I don't get my bike worked on by the dealer. 1 week to run my vin and order a part? I really try to buy parts/gear from them when I can, even if it will cost me 10% more, because I want to support local businesses. They just make it so hard to want to deal with them. At this rate I will be lucky to get the recalls done by the end of summer. My trip starts the beginning of August.

I finally managed to get Yamaha here in Australia to replace the ECU on my 07.

It was not a recall here in Australia.

Every time I went over the Marburg Range, a little hill and up the Toowoomba Range to my home, 550 meters, the ECU clagged out on me.

So it doesn't have to be a big change in elevation, and always as you descend.

I had a PC5 and Autotune installed, an a LCD200 to view real time data and data log the fault.

Spent a lot of $$$ on something that shouldn't happen.

Wasn't a nice riding experience when riding the Australian Alps, rather dangerous.

Our local dealership in Baton Rouge has an elevation of about 50 feet above sea level. However, the service manager knew that we took the bike to the mountains on our annual vacation and he took the initiative to get the ECU recall done on Dad's '07.

And... It made absolutely no difference. Nothing changed. The low RPM surging and on/off throttle snatch did not change. Of course, it did this regardless of altitude. For us, the ECU recall was a complete waste of time.

Adding a PC-V with a smoothness map and the G2 Ergonomics Throttle Tamer made all the difference in the world. Now everything is smooth as butter.

My '07 wasn't affected, either, and I took it the whole length of the Blue Ridge Parkway with elevations up to 6000 ft. I had the recall done, but saw no difference in the bike's performance.
