I'm running the SEII slip-ons, with a SE/AC and a K&N filter. My bike had the Stage I download done at the dealer. It ran lean. The map I started with is the '06 Dyna Stage I map... same as the dealer download... here is adescription from the Calibration ID file on the SERT CD-Rom -
Calibration # 32: 2006 Shotgun / Shorty Dual Exhaust with O2 Sensors
Configuration: 1450 SE A/C & Mufflers
File Name: 141NX001-A0.MT6
Components:
• SE Air Cleaner and Breather Kit P/N 29440-99C
• SE II Slip-Fit Mufflers P/N 80448-03 or 80258-99A
Ok.. here is what I started with. In advanced mode of the tuning screen, this is the "Closed Loop Bias" table. The numbers in the tables represent the mv for the O2 sensors.
Here is the same screen after I changed the settings. You can see that I increased a bunch of cells by two increments. Increasing these numbers causes the ECM to richen up the mixture for the RPM range on each row. It uses the data sent from the sensors to determine the amount of fuel to add to the mix.
Like I said, I could only ride a few miles, but it felt like a different bike. Listening to the exhaust note, it sounded a lot smoother too. Power was way up and running through the gears, the front end even got light. I still think there is room for improvement though. If it ever gets warm again, I'll work on it some more. Once I get it dialed in, if anyone wants a copy of the map, just ask. But fair warning here - I am no expert and this is my first time to use a SERT.
