Mapping Version

I meant to ask the related question: can I tell what map I have or do you have to plug it in at the dealer?

Anyone know if there is a different map for the US? The factory map has a bit of surging at a 55 MPH cruising speed.
Not that I have had the time to ride my new Stelvio much but I get a noticeable hunting when running along at 30/40 mph constant.Is anyone else getting this and is it a feature of the fuel injection on the Stelvio or something to do with the mapping. It is noticeable in as much as my pillion has noticed it and it is as though a plug or lead is breaking down. Any suggestions?
They all do it ! I think there is a different map available not sure of the code, I am going to ask my dealer when my bike is in for the engine recall, because mine hunts on constant throttle and is very snatchy rolling on and off the throttle at lower rpm's.

Is there any aftermarket fix that would help with the surging around 3k?

I had my map updated a long time ago. I forget the number of the newer map. I virtually eliminated ALL surging fo me.
But, I believe it introduced an issue with starting a cold motor on a hot day. Can't be positive.

There's a $100 band aid that some use, but most have removed it. I personally do not recommend it based on some horrible air/fuel data I witnessed on an A/F Dyno.
I haven't ridden the updated factory map on the Stelvio yet, but I did ride a Griso 8V with it, and while better, it still leaves much to be desired. The VDST we sell here will show you the map variant, among other things like TPS reset.
As a solid fix would be my GT-Rx ECU Reflash which is 50%+ better, and the limited run PC-V & AutoTune will resolve it 99%. I have likely found the problem to the cold start issue, and can resolve it on the ECU. I've had no takers yet.

Do tell. I don't remember seeing this elsewhere on the board, unless it's in the Carc section?
Keith, see; https://www.guzzitech.com/forum/topic. ... 060#p35060
I'm going to try it first, and if it works, I'll do yours if you want to come by or send me your ECU again if it works

I think that the 8V Todd is reffering to is mine, or at least mine is one of them as he took it out th other day. I don't doubt that some of the A/F numbers may be horrible but the thing is that the set-up I have on the US 8V with the Mistral Hi-Pipe is every bit as good as the set up on my Oz bike, if not a bit better. Todd reckons it 'Surges' a bit at 3,000-3,500? I can't feel or detect anything that feels like surging or 8 stroking? I really can't. It does feel lean and is a little more vibratory at that point on a light, constant throttle but surging ????
At the end of the day I've decided I don't need the PCV/AT for mine. I'm not saying it is a flawed product or that it won't make a bike run better, It's simply that I, a 55 year old fat guy with less than perfect eyesight, poor hearing and limited riding skills, have decided that my essentially 'Stock' bike does everything I need it to do and I don't need another layer of complexity. Thassall.
I have had the opportunity to ride Andrew, (Spaceclam's) 1100 though with the full box and dice package and it is a VERY impressive motorbike, an absolute torque monster with a completely linear torque curve like a VW Beetle bonnet! BEcause o that I've decided to give my PCV/AT to Jon for his 1100 as I believe that the 1100's need one more then the 8V's.
Couple of other interesting little things. My 8VG in Oz came from the factory with a 190 section rear tyre. I always thought this was odd and a bit of overkill, especially as the chassis is essentially identical to the 1100 which used a 180, but since that is what it had on it and it worked well enough every time I changed tyres I just stuck another 190 on the back. It's only when I saw my new one in the US that I realized that it has a 180 so I went and looked at the specs and sure enough the factory suggest a 180. So how the hell did mine end up with a 190 on it???? All I can assume is that there were no 180's available or they hadn't paid their supplier so the sent a few out with 190's on! I'm telling you though that the 180 is a much MUCH nicer thing than the 190. I'll be wearing the 190 on my Oz bike out and replacng it with a 180 ASAP!!!!
