Speedo Accuracy

The speedo on my 07 R1 is off by a few mph. Cann my local Yamaha dealer calibrate it, or do I need one of those speedo healers?

buy a speedohealer

i've ordered a speedohealer on Mon and can't wait to get it installed - thanks motomummy!

I wish I saw this earlier. I do not recommend a SpeedoHealer. I have a couple and I installed one in my 07. The 07 uses speed and rpm for several functions so once you re-align the speedo with a calibrator, at least 1 of the things that happens is the mapping goes off. I installed mine and ran it bypassed for about a week because I never got around to calibrating it with my GPS. Once I did though, it ran poorly. Sluggish and less hp. So I went back to bypass mode and it was instanly better. Took it out completely that day and never looked back. BTW, stock error is about 7%.

Describe how it "ran poorly". I have one installed now without a problemI wish I saw this earlier. I do not recommend a SpeedoHealer. I have a couple and I installed one in my 07.

I am also interested! I have also installed a speedohealer (a left over from my previous bike) and I didn't notice any difference in a bad mapping or a poor running bike. Can you please explain more? Thanks!

whats a speedohealer.

Does anyone know if a speedo healer from a 04 gsxr750 will work on a 07 R1?

7% which way?

Man this thread is all over the place. 1. A dealer cannot recalibrate a speedo 2. A speedohealer was designed to calibrate a stock speedo 3. There have been cases where the speedohealer has had bad affects on the 07

7% which way? Fast. i.e. at 100mph, you're really at 93. Or 180mph, you're really at 167.

Man this thread is all over the place. 1. A dealer cannot recalibrate a speedo TRUE 2. A speedohealer was designed to calibrate a stock speedo TRUE 3. There have been cases where the speedohealer has had bad affects on the 07 TRUE I don't know how much more detail you need when I say the bike felt sluggish and it lost hp. The only thing else I can say is it felt like I had a really bad map in a PC3. Except right now, I don't have a PC3.

question about installing & calibrating the speedohealer. I just got one last weekend and will hopefully be installing it this upcoming weekend. Easy? The on-line calculator deal is easy enough to figure out? Thanks

I either use the friendly road-side radar stands to give me a speed or my GPS.

You could be right when you say the speed sensor has influence on the mapping. See attached pages from the manual. The speed signal is used by the ECU for the mapping. I have my speedhealer at -10% (correction for standard correction and for my 16T front sprocket). When I set my speedohealer back to 0% correction I should sence a difference in bike performance. I will try this out next weekend.

Yeah, I would bet on that...

Update: weather is good! Will try it out this afternoon! more news tomorrow morning

Yesterday afternoon I have tried with different speedohealer settings. There is a big difference in engine power when the speedohealer is at 0 and at -10%. At -10% the engine misses some ponies. When the speedohealer is not functioning (i.e. 0%) the engine runs much smoother and has more horsepower. Conclusion: Ruffstuff is right and the speedohealer sucks for the 07 R1. But hey, now I am curious what happens when I put the speedohealer to +5% ....... No, I will not try it, don't know what it will do to the engine, when (if) it runs too lean.

Glad to see I'm not crazy! :rock I had mine set to 11.5% error (7% factory + 4.5% 47 tooth rear sprocket) and it was pretty noticable... There's alot of tech in that bike and I guess it doesn't like to be messed with...

I installed a speedohealer this past weekend - not too big of a problem - did not measure out the calibration -just set it for -7.5% Zero issues with the bike running differently with it in TFG. anyhoo - bummer @ some folks having issues....

Why is the speedo out by 7% to start with. Isn't this a fault? How can you do the constant maths to stay within the legal speed limits? Do all bikes have this faulty speedo reading?

All speedos are off and very from 1% to 14% on the extreme side. The problem can also get worse with a change to the stock gearing.

It runs fairly normal at everyday riding speeds... but take her out and give her a thrashing and then put the speedo healer in bypass and thrash her again and you'll easily see the difference. Or stick her on a dyno.

All speedos are off and very from 1% to 14% on the extreme side. The problem can also get worse with a change to the stock gearing. Yep. Most sportbikes I've come across are right in the 7-9% range. These are all bikes that use a speedo sensor off the countershaft sprocket. No one has ever come out to say why it's like that, but it is.

What if you dyno and have a custom map made after you install the speedo healer?

What if you dyno and have a custom map made after you install the speedo healer? I have a pcIII installed and a speedohealer on the way, I'd be interested to know if you can map over the issue. Anyone tried this???

I just put a new front sprocket, (-1), on my bike and oerdered a speedohealer. I am curious to hear how this goes for most and am hoping I dont end up with any issues. I know with just the -1 tooth the speedo has a HUGE difference now, reading 130 in first for example.

You'll probably have +5 to +8mph from actual at normal highway speeds, you're going slower than your speedo is saying basically :boom Spedohealer is a must, post up your %error when you get it tuned in. the %error is designed to prevent you from getting a ticket that you can sue the manufacturer over due to an incorrect speedo.

I truely doubt the speedometer has any genuine effect on the motors performance. Now with your speedometer in the unaccurate mode it likely reads, "faster, or higher". This could lead one to believe they are going faster; when indeed you are not. I would be very interested to see if anyone ran a pull on a dyno to see if the device truely effected anything. If the speedometer indeed affected your motor performance anyone who has a tire wear out, or changes gearing is going to have these problems. In fact anyone who does any modification to increase performance wich generally changes a given speed you may be going for any given rpm will have issues. I understand that the bikes have a gear position sensor, ambient pressure sensor, temp sensor and throttle position sensor that all effect the motors performance; but highly doubt the speedo does. If so many top notch WERA, CCS, and even AMA privateers would be having issues as many racers run very extreme gearing ratios at some tracks. (-1, +3, type combo's). Never once heard of them having issues with the motor because of the speedo. Indeed if the speedo was the problem the people who have changed gearing would benefit from a healer to put the reading back to stock.....and i doubt this is the case. I say buy a speedohealer and correct your odometer reading if you have made gearing or tire size changes.

06450F, the 07 R1 speed sensor does in fact affect the engine performance. As reported above, some people have had issues running a speedo healer on the 07. Also the lag that was experienced on the US 07 models, was an issue with the speed sensor. If you disconnected the speedo / speed sensor wire the lag went away, but you had no speedo. :fact

Seven people including myself all run a speedohealer V3.0 on our 07 R1s without issue. Most have the new ECU, I get mine on friday :sneaky :rock

I knew of a few on this site who were having issues and I also heard about it, from a local shop owner. It is interesting that the problem seems to be inconsistent. :dunno There are those however who have installed it and have not experienced any ill effects :dunno

Add myself to the list of happy owners of a 07 R1 with a Speedohealer V 3.0 that has no problems. I was aware of this thread prior to ordering a Speedohealer, I just took the gamble and hoped I would have no problems. For what it is worth I still have the original ECM installed.

Indeed, I'll report back once my ECM comes in and let ya'll know if I have any issues with it then, though I suspect not. Are those with issues sure they installed it right? A bad connection to a live wire could cause inconsistancy... my choice was to sauder the wire into the license plate light's connector located in the jumbled wires held in by the re-locking zip-tie. I simply slid the exposed wire into the connector, heated it up with a very small addition of sauder, and presto... instant connection without splicing and risking a bad connection / short. EDIT: When I get my R1 back and return from VIR I'll post some pics of where exactly I did this should anyone care to know. :)

Can someone who has experienced problems with the healer on an 07, post up what version they have. It seems the v3.0 works, perhaps those with problems are using an older version :dunno

I have a V3.0 speedohealer and have found problems using it on my 07R1. After installing the speedohealer it all seems to work fine, but it does not on high revs. Especially above 10.000rpm you will notice a lack of power. Try the following. Connect the speedohealer and set it to a correction of -10%. Ride the bike at high revs. Than stop and put the speedohealer in by-pass mode (set at 0 correction). then ride it again. You will notice a gain in power, especially on the high revs. You will not notice any lack of power when you ride the bike 'normal'. Maybe that is the reason why not all of the replies above notice the lack of power. Just ride it like you stole it, and then I would like to know your experiences. :)

I have sent an Email to Speedohealer about this issue, and her is the reply: Hi Jan, Thank you for bringing this issue to our attention. We haven't heard about it before. While the speed signal is wired to the ECU, bike ECUs do not use it for anything but diagnostics. The 2007 R1 could be an exception though. We will look for a test bike and put it on our dyno. For now, it does not make sense that 10% calibration would have an impact on performance. If it does, any sprocket change should cause loss of performance which would be unacceptable for a sportbike. In any case, we will investigate this issue. For those having issues I'd recommend to contact us direct. It might be that their splice for power is the source of the problem. Please feel free to post this response on the forum. Thanks again, /Norbert HealTech Electronics

I'd be interested to hear what speedohealer has to say @ the issue and I wonder how it is affected by a PC. I've got a PC3 on mine now w/ new exhaust and -1 in front and have it adjusted for -13.5% which I think is pretty close to being bang-on mph. I thrashed on her this weekend and the bike was pulling so hard above 10K it was nutz. 165 in 5th on a closed course straight & was still pulling hard when I had to back off.

How fast do you have to go before the error begins to show up? I went by one of those roadside radar gun signs and the speed it was showing was what my speedometer showed. I was only going 35 mph though so maybe the 7% wouldnt make a difference that slow.

Is there anyone that has the speedo healer on their 07 R1. I cant get my test light to come on. The light flashes once then about 12 times if I unplug it and then plug it back in.

I have an 07 with the "new ECU" and I have Speedohealer V 3.0 with no problems. I went -2 in the front with stock back. Mine is set something like 14%. I am not sure if its correct. Waiting for a GPS. And by the way the "new ECU" is great!!

Anyone in Oz having these problems with a Speedo Healer? I need a harness for one I've got sitting around, but I'm a bit reluctant to order it now!

I'm pretty keen to hear from people who definitely dont have probs throughout the whole rev range

go to speedohealer.com and have them do an estimate calculation. very simple task to do. will take you back to about 4-6% error with an estimation.

just a few thoughts about speedometers and speedo error. Most every passenger vehicle made will have error built into the speedo, that means your family car, your truck, and your bike. They will always read faster than you are actually traveling. This is done as a safe gaurd by the manufacturers. If for any reason you were traveling faster than the speedo said and got ticketed for such there would be huge lawsuits for the OEM's. The error is present at ALL SPEEDS. The error is a percentage. Lets say 10% because it's easier to do quickly. at 10mph INDICATED you will actually be traveling 9mph, at 70mph indicated you will actually be traveling 63mph, at 170mph indicated you will actually be traveling at 153mph... You get the idea. Sometimes getting bigger tires makes the speedo more accurate, and then running shorter tires has the oppisite effect. Tire wear also effect speedo accuracy and should be thought about when calibrating your speedo. If you set it dead nuts on an old worn tire then you will be traveling faster than indicated when you get a new tire. Better to set it when you have a new tire, and have it rear a bit higher as the tire wears. I have heard of some of the drag race guys having trouble with the gear indicator on the ZX14 when using the speedo healer, but have never experianced it myself. Speedo-Healer is a really neat product with a great plug and play harness for most bikes. Their instructions are overly complicated in my opinion though. Installing a speed-healer usually has the customer telling me their bike "feels" slower to them, because when they are at their normal agressivness they are seeing smaller numbers than they are used to.

It is not only the bike 'feels' slower, it definitely is on my 07 R1. I feel a big difference in performance with or without the speedohealer, especially above 10.000rpm. When I put the speedohealer to 0% correction (by-pass mode s to say), it has noticable more power. I have tried this in the same ride: First rode the bike with the speedohealer set to 10% correction and immediately afterwards set it to 0%. Very noticable power increasement above 10.000rpm. If I am correct there is a speedo signal going to the ecu and it is definitely used. My previous R1 (04) model did not have this problem. Probably because the speed signal was not used on that bike.

no I am not doubting you a bit brother. I was just saying the mental effect of a speedo healer thats set correctly is to make the bike "feel" slower, when in fact it's doing everything it was before. Thats not to say that in your case it's mental. If you have tried it both ways on the same day and notice a difference, then there is most certainly a difference. As the bikes get more and more tech on them these kinds of problems will be more and more common :)

I am going to install a 16t front sprocket on my 07. I was going to get a speedohealer but now I am not sure.

im glad someone started this thread i have an 07 R1 and i said in another post that i thought my speed-o-healer gave my bike some power, reason i say that i went with a 520 -1frt +2 in rear setup, drove it around for about a month and then added a speed-o-healer, set it to where my speedo is dead on and the odometer is off and it seemed like it made my bike come alive. It really helped my bike and then after another month i added a powercommander and put in another map and that helped it out even more, sorry to here it didnt help your bike, but have you had your computer changed at the dealer yet? i have maybe thats a differance, or not hard to tell

I am asumming that most people on here have had the ECU's swapped out, since the story broke here, about month before the new ECU's were even available. :fact

I'm surprised the PCIII doesn't have a gear change function in it. I have a programmer (EDGE) for my truck and allows you to change rear-end ratio, tire size, and some other goodies. Anybody ever asked the question to Dynojet (PCIII)?
