A: these are sold individually.
Q: Can I benefit from using this with my Dynojet Auto-Tune?
1 year 9 months ago
I was wondering if this would help my performance with my PCV & Auto-Tune. If so, which Type? Type 3 or Type 4? The ECU will be flashed. Also thinking of switching from my Bazzaz Z-Fi, Z-AFM & Dual Fuel Map Switch Selector to a PCV, Auto-Tune, Dual Fuel Map Switch Selector, POD-300 Display on my 2014 ZX-6R 636 ABS (ZX636FEF.) Would this device benefit or even work with this bike if I switched it over? Lastly, I'm trying to weld an O2 Sensor Boss to my 2007 GSX-R 750, however, the weld boss is curved, but the only place to add an O2 Sensor Weld Boss, is flat. Are there flat ones? I know this is 3 questions in 1, one having nothing to do with the device in inquiring about. Thank you
Q: Do I need an O2 Optimizer?
Over 5 years ago
My 2006 Roadliner is equipped with a big air kit and a Power Commander 3 USB using a custom map that specifies the O2 sensor be disconnected. Will the Optimizer do anything for me? Thanks for the help.

A: After speaking with Power Commander regarding this, they claim that the "Race Ready" models of the PC3 and the PC5 actually include the O2 optimizer. If the stock O2 sensor is active, it would override any fuel changes made by the Power Commander in the closed loop engine range, and basically make the fueling as it would be stock in that range. The optimizer disables the stock O2 sensor, so that the Power Commander can tune the fuel curve across all RPMs and throttle positions. If your map claims it needs the O2 sensor disconnected, then they have modified the fuel mapping in the closed loop section and if you do not have the optimizer, it would benefit your application as the changes they have made will not be applied in certain sections of the map without the optimizer.
