Not a stupid question at all!
I think it comes down to personal choice - I guess you could disable it, remove it and then ebay it on to the next chap if you wanted to. However, you can adjust the max amount of variation from the base map that the system will allow (I currently have it set to +10 to -7 from the set cell ammount). As you progress with increasingly more accurate maps (and your trims should start to get smaller and smaller) you can decrease these values (the default range is +20 to -20). That means once you are happy you can largely eliminate the problem on decel simply by not letting the system enrich over a certain amount (less then say +5 is not likely to have a dramatic effect on performance, assuming a good base map). Keeping the Autotune and using the max variation limits also means your bike will continue to refine and adapt as you put different fuels in, temperature changes, even air pressure or altitude. None of these should result in a dramatic change, so tight limits allows your map to remain on target for those AFRs regardless of conditions.
(its things like that which really make the Autotune stand out!)
Yeah I guess so, I was wondering what the lifespan would be like on the 02 sensors, say for instance it went bad, would that throw everything out or would it revert to the last good map, or would you have to replace it and start over.
I guess like a PC3 you would save a good map to your laptop and then reinstall it if the need arises???
