v7 iii red lights and rev limits !?

[chrisk]

I’ve nearly finished running in my v7iii and turned off the flashing red rev warning lights as per the manual.  I actually set upper and lower to 10,000 or something like that as I couldn't see an OFF function, either way the red lights don't come on anymore. I’m not the first owner and didn’t set them up.
BUT on my journey to work there is a rev limit kicking in at 5500 rpm, so I'm guessing there is another function somewhere ? I'm hoping it isn't a dealer first service thing ? I don't have the manual with me and sure I didn't see anything else when I read it about the Low and High settings.
 
Help

I haven't reset mine yet but I'd be curious as to the answer.

Yes I’m interested to know too as I’m picking up a V7 111 in a week or too.
When you say rev limit kicking in at 5500 rpm you’re referring to the red light rather than a physical rev limiter?

Welcome to WG, Pizza Guzzi, and congrats on your new bike!

I was thinking of the red light myself.

no, I mean a physical rev limit, unless there’s something wrong with the bike...
It just won’t go past about 5200-5500... I checked the manual and couldn’t find
anything.
So yes, the red lights are just a visual thing...
I’ll ring the dealer tomorrow.

Curious if you don't have a tachometer how you know which rpm the revs are cutting out at?

I have been under the impression the redline light on the bike is just to tell you you are at one of two preset levels.  One is preset to like 4,500 for break in and the other 6,500 which is the real redline for the engine.  My understanding is that you can set either light function to whichever level you want them to be at any time.

I found a youtube on this but I think I need to refresh my memory.

Who said I don’t have a rev counter.... The Bike is a Special

Something appears to be out of spec--from the manual. See last line re rev limiter.

Gear Shift "gear shift indicator threshold"
The gear shift indicator threshold is set in this mode. Press and hold down the "MODE" button to access the setting mode from the menu. Press the "MODE" button to select the required setting.
• SET GEAR SHIFT L: 4,500 rpm (run-in revolutions) • SET GEAR SHIFT H: 8,000 rpm Within the selected setting, each time the "MODE" button is pressed, the value is increased by 100 rpm. When the maximum value is reached, the display goes back to the initial value the next time the button is pressed. Press and hold down the "MODE" button to save the value set, exit the mode and return to the configuration menu. At the first key-on after setting, the instrument panel applies the last value set. When the engine speed threshold set is exceeded, the message "GEAR SHIFT" is shown on the display and the general alarm warning lamp lights. The general alarm warning lamp flashes when the lower threshold value is exceeded, and lights steadily when the upper threshold is exceeded. The general alarm warning lamp extinguishes once the engine speed drops below the threshold set.
The ECU limits the number of maximum engine revs to 7200 rpm

That is odd.  Let us know what the tech says.

Spoke to the dealer who said it’ll get reset at the first service - I’ve also  found something on the web that says the same, ie it’s a config item set by the factory or dealer.

I’ll know for sure tomorrow as it’s in for its  first service, can wait, a whole extra 2k which the bike needs to keep it moving nicely.

Rev on.

[Pizza Guzzi]

Yes it'll be interesting to see what the first service brings. Seems like they may have a physical rev limiter in case anyone ( not referring to the OP )  is inclined to ignore the red light.

[Daleroso]

Chrisk, what 2k are you referring to? Personal farkels, service cost or mileage @ your 1st srvice?

Answers below-

- The 5500 Rev limit on v7iii has been experienced by a number of riders according to the web and the solution is an ECU reflash. Mine got done on the third dealer visit, and even they originally said it’s related to the Rev indicator red lights set using the HL screen via the mode button, it’s NOT.

- Guzzi/piaggio don’t seem to be communicating this to dealers or riders, well not in my instance anyway. Whether it’s done to stop people blowing bikes up prior to the first service or a glitch who knows, either way it’s not user configurable and sorted under warranty with a reflash.

- I can now Rev to the red line.

Wow this is strange.

I have a v7 iii (Racer) and all has worked as expected.

Setting the dash (odo/tacho) Low or High RPMs just modifies the blinking red lights ... no communication to the ECU when you set those blinking light limits.  I think the real idea behind this was for people that only have the 1 unit (no Tacho, like Stones, etc).  So for bikes with the tacho (Racer, Special, etc), kind of redundant to see the tach and have blinking red lights.

Seems bizarre that some bike's ECU's come set to a lower max rpm limit and others are set at a higher (correct) rpm max.  Doesn't MG have version control of their ECU maps?  Each one has a number/name.  Hopefully your dealer can tell you what map you had and what map they switched you too. 

And while it probably isn't considered "user configurable", it is possible for an owner to change their max rpm in the ECU.  Get cables, get software, read map, edit map, write map.
