Don't forget to calibrate your traction control, it has improved mine beyond belief.
Its not done at the factory.

I don't even know how to do it. I guess I'll have to do it when I'm going to change the tires.

I am going to let you borrow my mp3 but don't crash it!!

how exactly do you do that?

I'm wondering if you should calibrate the ASR at the same time you change out your headlight fluid?

It's quite easy but trying to explain it slightly lengthy.
Page 38 of your Piaggio manual that came with your new bike, titled ASR system calibration procedure.

My bike took slightly longer than as detailed in the manual but now the traction control only cuts in when necessary as it was very sensitive before adjustment. I guess it was just slightly out of sync causing errors.

OK so it's true . Crazy it's not pre-calibrated .

here you go in case anyone needs it.

It wasn't an April fools joke.

My throttle control is a lot more positive with ASR on and when it detects a slip allows power back a lot sooner now.

I was getting the traction control lighting over the slightest bump and not allowing the power to return for some time.
The setup was bad on my 2016 bike but my 2019 one was so bad I started doing some research.
I was thinking Piaggio's traction control should be better than this??!

When it comes to the MP3 to Programming and the Manual.
If its not broke, don't fix it.

I have learned the hard way, what is perceived to be a problem can cause other headaches. Plus the only true support is here on MV, as most Dealers don't have a Clue.

I put up with the poor traction control for 3 years with my last bike hoping the new version would be better.
But imagine my surprise when the new bike was even worse.
But with a little research I found an adjustment that has transformed the bikes power delivery, just thought id share this amazing adjustment with this great forum.

So... after being denied power after a normal acceleration from a stop one too many times, I decided I had to do something. I have the US 2020 model which appears to be the hpe engine on a mid-2019 body. I confirmed that the dealer had not done this ASR calibration before I picked up my MP3.

Here is the procedure I followed:
ASR SYSTEM CALIBRATION PROCEDURE.
In order to maintain the effectiveness of the ASR system following the replacement of one or more tyres a calibration procedure of the system must be performed as follows on a straight flat stretch of road.
It is necessary that the diagnostic phase of the ASR systems and ABS is complete: for this purpose, after switching to «ON», ride a short distance above 5 km/h and wait for the flashing of the two warning lights to stop.
Allow the engine to idle for at least 5 seconds.
Pull the brake lever and press the ASR on/off button «1» simultaneously for at least 3 seconds. The activation process will be confirmed by the ASR warning light «2» turning on with slow flashing.
Accelerate to a constant speed of 30 to 40 km/h and maintain it for at least to 8 seconds. The continuity of the vehicle speed in the correct field to complete the procedure will be confirmed by a very fast flashing of the ASR warning light «2».
The end of the procedure will be indicated by the steady lighting ASR warning light «2». The ASR system is not active.
Once the procedure is complete it is necessary to switch to «OFF» and wait for at least 60 seconds before being able to switch again to «ON».
In case of failure to complete the procedure within 5 minutes the ASR warning light «2» will stay on steady and the ASR will remain off until switching to «OFF».
To switch again to «ON» it is necessary to reactivate the ASR. It is however necessary to repeat the process until it succeeds.

I tried to initiate the traction control calibration protocol a few times before it finally started responding as described in the manual. There is one difference I observed three times from what is described in the manual, and that is after at least 8 seconds at 30-40 kph where the ASR light is flashing quickly, the ASR light *turns off* rather than lights full on.

Has anyone else observed this light off vs light on when the ASR calibration completes?

Update: tested thoroughly and traction control is much improved after performing this calibration! No longer losing power when trying to accelerate while turning onto highway.

Ah yes! The headlight fluid. I must change mine soon. Thanks for reminding me...lol.

I tried finding headlight fluid but all I could find was this:

http://kalecoauto.com/index.php?main_page=product_info&cPath=9&products_id=22&zenid=ZeGS0fLtsaA46BWgWZ-XQ3

Can it be used instead? I really need to know that my headlights will continue to function properly.

Thank you.

Yeah, I thought I'd give that a go. Unfortunately, since I filled my blinkers, they seem dead so maybe it's the wrong fluid. I'm not sure if to risk it in the headlight. Currently there is no fluid left in the headlight. I'm thinking it's probably ok to just go ahead and fill the headlight. What d'ya reckon?

Har! Har! Har! You Guys are a Riot!!!!!

You need more TR double E's. That is the whole problem.

Hello everyone. I am new to this forum and i am from Norway so please don´t look too much on my writingerrors. So now to my problem as i experienced it. My Mp3 500 with model year 2019 suddenly lost power when accelerating through corners and out of roundabouts, the asr light flashing at the same time. I filled air into my wheels and it was suprisingly low preassure in all wheels, there and then i remembered somthing about calibration. I am not able to calibrate it as it is shown in the manual, i cant seem to get in to the calibrating stand. It says PULL handbrake leaver and press button, does it mean to activate the handbrake or push and deaktivate the handbreake, anyhow, it did not goe as deskribed in the manual. It may seem like it is a difference betveen 2017 up to 2018 models and above as i have found on the big internet. Hope someone has done it on "newer" MP3`s and can tell me what i am doing wrong.

Best regards Normarco

I have a 2020 sport
I rode around for a while wondering why it would fall flat,
The error felt like a cv carb with too big of a jet controlling the diaphragm
I adapted by twisting the throttle slower, until I noticed the asr light flashing

Found this thread & calibrated the asr system

To answer the question:
Pull one of the brake levers

The light didn't flash during the calibration [ride 20-30km for 8 seconds], worked anyway

I'm happy not to have to work around what I thought was flaw...

Great job, it was only owning another MP3 that made me realise there was anything "wrong" and that needed adjusting.

Thank you. For all what i thought I was fixed on the handbrake for someone reason. When you answered BREAKE leaver i suddenly understod why I had problems. Did the calibration and the lamp flashed quicker and quicker until it went dark, drove some sekunds after that and turned off and waited for 60 sekunds or so. The bike is a lot better, really a lot better. No flashing light from the lamp and loss of power at the same time when at WOT, thank you again to make me understand what i did wrong.

Best regards

Still trying to decipher the instructions into an actionable process.

1. With ASR "ON" ride a short distance above 3 mph
2. Allow engine to idle for 5 seconds
3. Pull Hand brake simultaneously will pressing the "ASR" button for 3 seconds
4. Accelerate to a constant speed of 18-15 mph for at least 8 seconds (ASR will flash fast)
5. After procedure switch ASR "off" wait 60 seconds; then turn on.

Questions:
1. During step 2 am I coming to a stop before step 3?
2. After receiving flashing light do I continue to ride until the light becomes constantly on?

Yes (come to complete stop) and yes (start from 0 mph) AND you must keep a steady 15-18mph for about 10 seconds without braking or accelerating until the ASR light goes solid

Thanks for the tips- that did it! Huge difference.
