DDFI-3 tuning with stock o2 sensor

[mcaff]

AZ, are you sure TunerPro let´s us change rpm values? I couldn´t figure out how to do it. Check the screenshot below:
Attachment 6811

There are three greyed buttons and the first one reads "Edit linked X-Axis table" which perhaps is the function needed to change RPM values. However it is disabled, can´t use it.

Just figured it out how to do it!

For those ignorants like me here we go:

Hence this comment I made
"You need to just enter all the rpm points you want in the fuel map axis table."

Yes you were absolutelly right.
Will get the BUE2D ECM installed today and will upload the map I created with more resolution to see how it runs.

Not sure how he did it, but Mike programmed several 1125 ECMs for XB use.

I imagine he just flashed an XB firmware on them

XB and 1125 share the same hardware and firmware, but with different parametrization.

Just marking this thread. Getting the courage and other projects out of the way first to do some datalog tuning this year.

Ok, so, I successfully installed a second O2 sensor and is working properly. Just add the sensor, add the pin to the ECM, and turn on the independent front cylinder closed loop and log front o2 settings in tunerpro.

Amazing!
Looking forward to adding the front o2 to my bike.
Did it feel any better running with independent closed loop? More smooth maybe? At least the mileage per gallon should improve.

Not too sure yet, only have about 15 miles on it. Also, it's a different ecm and tune than I had. One thing I did find out was the BUEOD DDFI3 ECM does not allow a second O2 sensor. So, I had to swap back to my EBR race ecm. Which I also had to figure out how to turn off the stupid speed based fan control.
