Regarding performance upgrades, it seems a Power Commander is a standard go-to for most other makes, even HD's. Why have I never seen them used with Buells? | ||

HD uses a different FI system than Buell did. | ||

They exist but don't work great with Buell DDFI. Tuning a Race ECM simply works better. | ||

The piggy back tuners and the DDFI system fight each other and you get nowhere with tuning. Reflashing the ECM or changing the ECM is the best way to go. | ||

The problem stemmed from the Buell's "learned fuel area" because if you used the PC to tune in this area at anything other than the 14.5-15.1 it wanted to see the ecm would change the entire map so the O2 sensor saw that ratio again. You could use a PC if you knew where your ecm's Learned Fuel Area was and left it alone. But why bother when you can use Ecm-Spy for free---? | ||

Firemanjim is spot on. I bought a Dobeck Performance tuner for my '06 Ulysses. Epic fail! The first unit was DOA. The replacement worked (?) But it never produced any difference in performance. At least that I could detect. Removed it a few months after installation a $233 lesson learned. Don't waste your money on any piggyback tuners for your Buell. Better to get an OEM race ECM. |
