V7 II Special idle speed adjust

[Wes Stephens]

My 2015 idles a bit above the spec of 1350 rpm + or - 100 rpm and I thought my shade tree mechanic skills over 55 years or so could take care of this minor problem.  But I'm stumped.  I downloaded the Service manual from Guzzi Tech and didn't find a way to adjust it.   Does it take a computer hookup to do a digital tweak to the CPU or what.  I took the battery out to look at the throttle body and TPS but nothing, that I could see, with a slot or knob to twist???   The bike runs fine and I hesitate to screw it up.

Might be worth a TPS reset first.

 Wes , my understanding is idle speed is controlled by the ECU . There is no mechanical adjustment , put the screwdriver away

My V7ii Special idles exactly the same, and I also found nothing in the manuals.  I am sure it's software controlled, but it doesn't bother me enough to dig deeper.

Post if you find out how it's done.  Thx!

There is a table in the software called Idle RPM in which you will find a table of Idle RPM versus Engine temperature. The table is 1350 RPM from and including 40 deg C up to 125 deg C.
The table goes from 1650 RPM at -30 deg C to 1375 deg C at 30 deg C.
Perhaps your engine temperature sensor in the RH head is faulty. If this is the case, it would also affect the'Ignition Temperature Correction' and the Fuel Engine Temperature Correction' tables that use the Engine Temperature.
Possible effects:- Perhaps some pinging on a hot day. Higher fuel consumption.
The engine temperature sensor is a bog standard water temperature sensor (without any waler) and probably should be improved with the addition of some anti-sieze paste. Peter Roper had described a good technique for doing this.

I would really, strongly, advise against that.

[organfixsing]

On a V7II a TPS reset is not applicable, however, it is advisable to do an auto learning parameters reset as explained by Beetle.

V7, MIUG3, we don't do a TPS reset, instead:-
Reset your auto-learning parameters. In 'Measurements'.
Check the reading for 'Throttle'. It should be 0.9 or 1.0. If the reading is anything other than 0.9 or 1.0, then (and only then), follow these steps:

1) In the top menu, go to View -> Actors
2) In any of the drop down menus select :
"Reset autolearning parameters", then click start
3) In any of the drop down menus select:
"Throttle self-learning", then click start.
4) In the top menu, go back to View -> Measurements
5) In any of the drop down menus select:
"Throttle", the value should now be 0.9 or 1.0.
Hope this helps.

Idle is not adjustable mechanically. Is it really idling high?

Does the idle change when moving the bars from full lock to full lock? If so, check your cables.

[organfixsing]

Hadn't thought of that. Me, always going for the technical, not the simple. Should b the first check as people may not have checked that.
Cheers

Thanks to all the inputs, I'm an old dog but try to learn new tricks.  The response from jpv7 is probably what I'll do.  The slightly high idle,  around 1485 rpm, is consistent  regardless of temp changes.  I'll just remember the old saying "it's close enough for government work" and keep on riding.

If you are eager to learn, get the software cables and learn cause it's not to bad. I was in the same place but I had to learn to stay currant as a Guzzi  mechanic. I used to be anti dot com.

[Wes Stephens]

Thanks guzzisteve,  It's time I learned something useful about modern bikes.  I have a laptop and could download software app to look inside the Guzzi brain.  Just need a cable to plug into the bikes port,  right???   I need a little help here.

How are you ascertaining the idle speed? If you're using the tach I wouldn't bother. They tend to be only a rough guide. Once you have some sort of diagnostic scan tool like Guzzidiag you'll have a much better idea of what is actually happening.

My V7 ii never idled below 1400 rpm according to the rev counter. So I downloaded GuzziDiag and TunerPro as per various posts, bought the appropriate cables from Lonelec, and started tinkering. Having read and saved the standard ECU map, I modified the Idle RPM table so that once properly warmed up it idled at 1200 rpm. No problem! Since then I've progressively modified the map so it now idles at 900 rpm once it's fully warmed up. I get better engine braking and easier low speed running. I've no idea why Guzzi set the standard idle speed so high, unless it's to possibly avoid the oil light coming on if you've been stuck in a traffic jam in Rome for an hour in August. Happy to freely share details with anyone who's interested.

[Vagrant]

They had a reason for that speed. I'd price a rebuilt engine first.

[rodekyll]

What's the hot oil pressure at 900?

[pete roper]

Given that the light comes on at about 2PSI I'd be real worried if it came on at idle.

I can't understand why people want a low idle speed? Want that? Buy a Panther!

Why this caution against MIUG3 throttle reset? I read:

"Reset your auto-learning parameters. In 'Measurements'. Check the reading for 'Throttle'. It should be 0.9 or 1.0. If the reading is anything other than 0.9 or 1.0, then (and only then), follow these steps [...]"

I've done this reset several times and to me it appears to be a software reset only, involving no mechanical action. There is absolutely no sound from the bike. No whirring, clicking or anything else to suggest than anything is moving. If I am right, that this is a software only reset, I should then be able to do a thousand resets with no harm at all. But the guide suggests otherwise. What am I not understanding here?
