Just had the recall done today. Rode home to replug PCV wires into new harness wires and checked throttle calibration. Min voltage says 0.690 mine hovers around 0.681 and 0.684 and has dipped into the 70's bike has the dig. fix it is farly stable with normal op temp. Gonna be watching this closely. Before the recall it never went below min voltage.

Well I am happy to report that I was able to source the recall kit and will be doing this simple fix soon.

connolly1: I like you and many others watch some parameters on the bike that some people don't even know exist or know how to check and on the surface it all seems fine all UNTIL that Huh! moment

The documented modifications I've done only I know and there is a high chance that the dealer will mess something up. I for one don't want to be taking everything off my bike just so they can fit this fix. This is simple enough to do and I can take my time and get the job done properly.

Yamaha Australia are doing the recall for no cost at bike shops so no mistakes can be made.

"No Mistakes can be made" WTF? That might be the case for "100% original" bikes like yours. Not sure what planet you live on mate to make statements like these. You were either extremely lucky or ignorant. And FYI every manufacurer does re-calls for free.

DIY recall complete. Took me about 4.5 hours in total and If you have a modded bike I can garantee you the job can't be done in under an hour that dealers were allocated by Yamaha Motor.

All the changes are feeding the smaller ECU 26pin connector and will affect those of us that have a PC V installed. Taps into Digital ground (Black/Brown wire) and TPS (White Wire) need to be re-done for the PC V. We will also need to reset the TPS signal in the PC V as the voltage after the fix is different than previously setup I've noticed. The problem is that on Throttle by wire systems this can only be reset successfuly on a dyno.

DIAG is reporting no fault codes and TPS and APS readings are solid and as should be.

Pretty simple and straight forward fix if you know your way around electronics and engine bays. So for those of you that don't feel comfortable or have bikes in mostly stock form, I would leave it to your dealer. For the rest of us a DIY might be a good option.

I am seeing the exact same thing.
This is due to PC V now receiving a different voltage than on the previous harness. My gut feeling is that we need to re-callibrate our TPS signal in PC V and we need to do this on a dyno.

It can be done without a dyno:
The idle (low V) setting is easy anyway as long as the motor is fully warmed up. It's the full throttle V that's difficult.

1) Use Diagnostics (D13 I think) and when I checked the PCV TPS voltage using this method it was within 0.01V of the real world reading (Dyno/Road) which is probably well within the repeatability of the measurements being used. (Amazing considering the bike system voltage when stopped is approx 12.7v and when running around 14v)

2) Laptop with PCV software running in a rucksack doing the TPS calibration for real on the (off)road in the gear of your choice (i.e. off highway, closed course, obey all local roads, ride responsibly etc., etc.)

3) Use the Dynojet LCD-200 screen which is essentially the same as (2) but without the rucksack/laptop.


Oh yes, it has to be over 6000rpm for the throttle plates to be fully open I believe. Suggest lower rather than higher gears and for the more insane amongst you don't forget without the TopSpeed fix or Race ECU the throttle plates will start to close in 4th. & 5th. gear if you go fast enough (don't know if this actually affects the MEASURED TPS voltage though!!!!!!)

Have Fun!!! Ride Safely

Hey HossMan,


Thanks posting the instructions by the way. Legend!

Can you elaborate a bit more about your Option 1 Above?
Feel free to PM me if you don't want to hijack this thread.
How do you actually set it using the DIAG as a guide.

The issue I have is that PC V should show 0 at closed throttle naturally and about 37% at wide open throttle (WOT) while stationary as butterflies aren't fully open unless you reach over certain revs.

My TPS shows 100% while stationary at WOT.
Not sure how to re-calibrate my PC V using your option 1 above
Thanks.

Just to clarify I've just double checked with my bike and using the Diagnostics mode in:
D01
D13
D14
D15
The throttle plates "actually" move to the full open position when the twistgrip is turned full (look on the left of the bike at the rear TP spindle, you'll see what I mean)
In each (Diagnostic) case the PCV TPS voltage will go through the full values. I stress PCV TPS as the voltage we're interested in is the one from the CORRECT TPS wire for the PCV as per the install instructions.

So to use Option (1) have the laptop hooked up to the PCV with the bike in Diag mode as per the above.
Note: I'm assuming that you have the PCV powered from a switched 12v source and not as it comes getting it's power from the plug-in PCV-Fuel injector plugs?
Also I assume you've separated the "normal" PCV ground from the PCV TPS Ground wire in the PCV harness?
Then just do a PCV TPS throttle calib within the Power Commander 5 software (running on your laptop/computer connected via USB cable)

Hope that helps?

Oh yes I just checked mine with my on-road (sorry I meant off road test!) and it's still within 0.01v of the max I got during the (off)road test.

My TPS shows 100% while stationary at WOT

If you are seeing this from the laptop/computer Power Commander 5 software AND you're not in diagnostics mode then the wrong signal has been routed to the PCV (most likely one of the APS signals)
