I have been experimenting with using a wideband sensor to dial in the wanted AFR to the 5AM. There's a couple of issues.1. The 5AM expects a narrowband Rich/Stoic/Lean signal only. You must program an analog output to emulate a narrowband signal, but you can still choose your target AFR as your 'Stoic' point.2. You can't use an LC-2. The LC-2 has a single ended output. A differential output is required or you get a SERVICE error. :D. Fortunately this is a good thing, because it completely eliminates the offset voltage noise problem.
With my lc1 it works. Is the LC2 different in the connection? Just one wire connected.
Interesting. No, they have the same wiring. Ill have another try soon, but at the moment my LC-2 is attached to a 1200 Sport with a roller top end.
I have my stock map from Stelvio. 2229STA42Z from 2011.03.03.It is practically identical to the 2229STVAD42 2009 NTX. Only difference is that I have Conti ABS (1547).Question 1: When I first started the bike the temperature of the engine was 0C (32F) so according to the Idle RPM table I should have 1400rpm. This value was also displayed in GuzziDiag under calculated RPM. But my Idle RPM was 1120-1180. When engine reached 60C (140F) idle was settled at 1200RPM. At 100C (212F) - 1225-1250. According to the workshop manual idle speed is 1100 +- 100 RPM. I have no fault codes stored. My Stelvio fires up like this one: https://www.youtube.com/watch?v=VQifE1Q5nc8Is it possible to tune the map that my Stelvio would fire up like 8V (https://www.youtube.com/watch?v=1ML9WgHuAKA)?If 1400 rpm when cold can't be achieved why such high values are stored in the ECU? Question 2: Lambda 1 reading where always around 190mV during my test. I rev the engine up to 5000rpm and live it there for about 15s but nothing has changed. I understand that Lambda sensor is faraway from the cylinders but isn't it suppose to switch between 100mV nad 1V? Question 3: My TPS was set at 4,6-4,5. According to the workshop manual it should be set on 4.7+-0.2. TPS reset haven't changed the value. Question 4: Is it normal to have noticeable popping on engine breaking? Stock exhaust. Test on central stand. Rev it up to 6000 rpm and close the throttle. Popping can be heard from the exhaust. Chris
I must say that You have very nice cold start. But You have a 8V. I've noticed that the 8V stelvio has a much better start up than the 4V
Is it a good idea to buy innovate LC-2 kit and tune the map for AFR 14.0 across entire map? I've done it on my F650CS with PowerCommander. Huge difference.
marketing made 8v stelvios :-)The same they did with the gt8v norge and 1200 sport 8v and griso 8v.
thanks beetle, so i edit the V11's called15M maps even though I have the 15RC in the vintage.Has any one edited a California vintage map to help with the slight hot detonation that I can compare to mine. other than that it is running good. ??? or perhaps if the dips in the maps are not the cause, i should be altering another value as the detonation sounds like just the left cylinder.i have checked every mechanical part is seated and tight.

Is it detonation when accelerating? You are in the usa with the bad gas you have there? I know a member here lazlokovacs has been busy with that with a vintage. Send him a pm if he has a map for you
Yes. The dips are there due to the volumetric efficiency of the engine at those RPM/TPS breakpoints. I wouldn't try to tweak them without knowing what is going on when you get detonation. If you are only getting it during hard acceleration, you may try adding some fuel to table 05 (ACCEL ENRICH). Take note of the RPM and (if possible) the throttle position. You can then get the TPS breakpoints from GuzziDiag by holding the throttle in the same position (without engine running of course). Don't go crazy and only increase in small amounts and then test ride until the pinging stops.
compare your values with these. For changing, the current engine temp is where to look and change.
I've changed my worm-up map and i finally getting 1400rpm. I have one more question. In section Ators there is a engine on stepper motor option ? What does it do?
