Hi Pash.
I have re-set the CSE to -10C to 160%, 22C to 120%, 65C to 110% and all the others to 100%. Going from -10C to 260C for CSE does not make any sense to me. Can you change these as I would have thought a more linear value would be better.
What does WOT stand for.
Changing the CSE will make very little difference IMHO as:
1. when the bike is in closed loop anyway, so it will never run richer than stoichiometric
2. when the bike is at WOT (Wide Open Throttle):
a. the AFV, which is calculated in the Closed Loop Learn area will be applied
b. the Open Loop Learn Enable will be active and will ensure that the engine (REAR CYLINDER) will never run lean
I am not 100% sure what you want to achieve. CSE is purely a correction for engine temperature. You want to run rich when cold cos you get fuel condensing on cold cylinder walls (the choke), and you may want to run rich if the engine is overheating (latent heat of vaporisation assisting cooling). I don't think the map should be linear, and TBH if you warm the bike up before you have expectations of performance, you will never be in the low temperature area. I have never had any reason to want to change this correction. I have, however, had ideas about changing the front cylinder correction (check my diagrams) as a function of engine temperature. This will not be over-ridden by the lambda sensor.
The secret in order of importance, IMHO, is:
1. a good Front to Rear map relationship
2. an accurate map
3. accurate corrections
I have not had the chance to trawl back through your posts and I still don't know (or have forgotten) what the issue is.
