Ok guys just checked AFV's front 90 and rear 89.5 is this a lean or rich condition? This is how I have the bike set up currently no inner air box lid, K&N air filter, Jardine fuel card, and Drummer exhaust. Thanks for the help guys | ||

I forgot I have not made any adjustments to the Jardine fuel card just plugged it in. | ||

lean! but if those are 'learned' values, I guess thats what your bike likes. just seems a bit extreme.... | ||

Bott, that is with learned values around 650 miles without the inner airbox. I think i'll put the inner air box lid back on and put a few hundred miles and then check it. Thanks | ||

Those numbers are close to what my "learned" values were, 92-94. I'm at 5000' ASL tho and the air is thinner up here. Z | ||

We are at about 3,000 elevation here. so not to far off then cool. | ||

from what I can gather and there are owners out there that know far more than I isn't any value less than 100 effectively the closed loop learning mode leaning off the mixture for the closed loop? This AFV is then applied to the open loop map which is by definition running a weaker mixture for this mode due to the AFV being used as a multiplying factor and being less than 100%, I thought altitude corrections were handled by another map correction factor from the baro and air temp sensors?

Bott said: "lean! but if those are 'learned' values, I guess thats what your bike likes. just seems a bit extreme...." I know you mean lean, Bott, as in the factory programming but if I'm not mistaken doesn't that just mean its not seeing as much air coming in and adjusts the FUEL down from an average of 100 to keep the factory, already lean, ratio? Zac and I are in the same range because of our altitudes also; we're just not seeing as much air/oxygen. I know it does not make any sense also, with K&N, inner air box off and more free flowing muffler. Where am I going wrong if at all? Bob (Message edited by bob_thompson on November 24, 2009) | ||

Still thinking on this and just maybe the ECM sees so much more air coming in that it adjusts fuel up and them says, wait a minute thats too much fuel and kicks it back. Now I'm really confusing myself?????? | ||

Bob T Thanks, I think I understand better now | ||

A more open exhasut doesn't always equate to better flow. Most slip-ons are not the proper length for optimum exhaust flow in the mid-range rpm regions. In the closed loop learning region, the pipe could even be working against you by placing the high pressure reflected wave at the valve during overlap. (This is just possible speculation) Also, where the closed loop learning region is, the engine is under relatively light load so the filter and romoval of the airbox don't have much of an impact on airflow as there is plenty of time for the standard airbox and filter fill with the required volume. | ||

Mine have always been below 90 but over 87 since I learned to check them. I now have a couple thousand miles and a jardine slip on and they didn't change. Is there a way to reset the values or is there no reason worry about the "lean" numbers showing up. | ||

If this "fuel card" is adding fuel in the closed loop region, that would explain the lean AFV's. For reference on my stock bike, my AFV's are 105/105 and i'm almost at sea level. 400 feet above I think. | ||
| Dirty_john |
mine were at 100/100 with the standard can with cat (sea level or there about), with a remus can they were 100/100 for months and have recently gone to 100F/85.5R, so the bike is going in to the dealers Saturday because this scale of change is worrying when all other variables remain the same, I have a K&N filter which I fill fit over Xmas, standard filter is clean. I will post any findings the dealer comes up with next week |
