:think: Unless you are changing a sensor or rebuilding your engine why would you need to reset adptives? Adaptive values are ... well, adaptive. From what I ahve been told, and from experience, they only need to be fiddled with after a major rebuild where a sensor may have changed adjustment during a reinstall or after changing a sensor. After enough miles things will be relearned in your ECU.
My first reset was after changing fuel injectors, cleaning MAF, and changing O2s. The combination made a huge increase in my MPG. I have reset a couple times since with little or no difference.
In fact, i really like to clean at each service items like MAF.
Another reason is that i have a single point LPG install. Believe me when i reset, i can see the difference and even smell it. That thing richen to the max the fuel with this setup and since i do not have Cats, it fumes black like a chipped diesel.
Ok i know i should change it but since i'm not confident enough to swap a front end kit only, i'm not ready to spend something like 2500 GBP on a old rig for a newer install. If i want performance or economy, i can buy another car for this amount.
I saw cool XJR with RHD for ridiculous prices

(from 3000 GBP to 6000) and i have a twingo 94 for economy and city bumper to bumper parks.
