Hello,
I just got the new SEST software and while playing with the smart tune I noticed there is a set of maps/calibrations for the 2009 as well as the 2010.
I understand that there were no engine modifications between the years yet there are differences in the maps. I noticed the closed loop bias is gone in the 009 version (2010) when compared to the 205 version (2009).
The rpm limited has gone down to 6100 from 6200 and the Afr table is also different.
Does anyone know why the difference?
I'm not sure however I think the lack of the closed loop bias in the 2010 ECU map tuning is somehow related to the new fuel type settings that can be used for tuning. There are no fuel type options when tuning the 2009 bikes however when tuning a 2010, you can choose normal gas (which has higher - leaner AFRs). You can also choose a 10% ethanol fuel setting which lowers (enrichens) all the closed loop AFR settings. And lastly there's a 25%(?) ethanol setting which really lowers (enrichens) the closed loop AFRs.
It would seem to me that if someone could figure out how to convert regular 2010 ECU maps to "25% ethanol" fuel settings, while still using premium gas, you could actually get the closed loop portion of the map to run in the mid 13's AFR. I'm just not sure how to go about modifying the VE tables and the spark advance tables to take advantage of these fuel settings when you actually have good fuel to run on.
I'm sure someone smarter than me is going to figure out how to take advantage of the fuel type settings in the 2010 tuning maps to maximize performance instead of accomodating ethanol fuel. I just haven't been able to figure it out. Has anyone explored these fuel settings for improving performance while still running premium gas?
