PCV recalibration question.

[WarpSpeed]

Instead of hijacking another thread, I thought I would start a new one.
In PCV user guide, it says "The speed and gear position were setup with stock gearing and stock tires."

I am running -1 in front.

So does that mean, I need to recalibrate the gear position and speed again? I can do it I know its simple as, but just wanted to confirm.
Thanks for your help in advance.

Yes...you do need to recalibrate it. If you find some difficulty in figuring out how to do it there is a thread in the Do It Yourself section on how to enable AFR ratios for the PCV in every gear...check that out and it explains it.

Found it. You are awesome bunch of guys here It even mentions about gearing change as well but somehow search couldn't locate it. Thanks much....

Step 5: Calibrate the Speed Sensor/Signal from your bike to the PCV:
You will need to do this before you can calibrate the PCV for Gear Calibration (next step). This step is performed with your bike running and your laptop's USB hooked up to the PCV. DynoJet recommends using a Dyno (safety reasons); I used a rear stand and tried to ensure the bike couldn’t move around much… make sure your rear tire is safely OFF the ground. With the PCV hooked up to your laptop and the PCV software launched, click on the “Power Commander Tools” drop down menu and choose the calibrate speed option. When the popup window appears, you will enter a target speed (I used 25mph). Then you will rev your bike up to the target speed you entered - 25mph in this example (1st gear is fine, but gear selection doesn’t matter), once your dash/speedometer reads exactly what you entered as your target, you will click calibrate. Now the PCV software should read the same speed as your dash. Click OK and proceed to next step.

Step 6: Calibrate the Gear Selection for the PCV:
If you haven’t calibrated your speed sensor at this point, STOP – do that prior to proceeding. Now click on the “Power Commander Tools” drop down menu and click on Calibrate – Gear Calibration option. This will bring up the Gear Calibration popup. You will do similar to what you did in the previous step (with your bike running), except speed is not a big issue, just steady throttle. I used my throttle lock in both cases (this step and the previous) but you can do it with a steady hand too. You’re going to put the bike in 1st gear and hold the throttle steady (speed isn’t a concern, just hold the throttle steady); I think I only had the rear wheel spinning around 15-20mph. Once you’re steady on the throttle, click “Calibrate” for Gear 1 on the popup that came up. Now put the bike in 2nd gear and hold the throttle steady again, click “Calibrate” for Gear 2. Continue sequentially switching into the remaining gears until this process is complete for all 6 gears. When finished, click OK.

EDIT - if you change sprockets after you have done the speed and gear calibrations, you will need to go back into the software and do the calibrations again - this is due to the speed signal changing due to the sprocket changes (going up or down in teeth)

Does the PCV gets the speed signal from the TPS wire...
If not then how does it knows what speed I am doing and how will it calibrate..

My setup is just PCV with nothing extra like SFM/autotune... just PCV with TPS plugged in... I am confused... can someone help please...

Wow, I had no idea these two steps were required when changing gearing!

[WarpSpeed]

I am not saying they are required.
I am still seeking confirmation on it as first time I read the manual and it left me confused so I am waiting for other members to help me...

As I remember if you change the sprocket the speed accuracy does not change because the signal is been received from the ABS sensor in the ABS models.Now the gear position might need recalibration.

Do you need to do this for a standard PCV map, or is it just if you run a map for each gear?

[DrIoannis]

I believe that if you do not have a gear depended map you will not need the calibration.

True.

The more I thought about this, I seriously doubt these procedures are required for the S1000RR.
