Autotune Kit: Spare Parts

This unit is easy to install and works great. I love it. Should have installed earlier. Maintains correct settings regardless of fuel or altitude changes.

Pros
  • Glass Connector Cable
Cons
  • Hard to Tell

The items in the box are not as listed.

Two stainless steel sensor plugs are missing from the box, one of the A/F sensors has lost its protective plastic cover, this kit was definitely returned to a previous buyer who did not install it.

Pros
  • and two sets of welding lugs
Cons
  • Operating Speed

An amazing addition in the absence of a tuner.

Great device. Does a great job tuning your bike if you don't have a dyno tuner. Don't set it and forget it. You also need to take the time to learn how to use it.

Pros
  • Two custom sensor cables
Cons
  • Modern

Great when it works

This works great, after a lot of fiddling with installation, very sensitive to power supply, needs to be connected directly to battery or it will work Not. Spent several hours with tech support to finally resolve the issue. If the device is flashing and the light never stays on, the O2 sensors are not receiving enough power. Knowing this would have saved me many hours of troubleshooting.

Pros
  • Also needs ground and +12v connection with wiring hardware included
Cons
  • Some difficulties

I like the push pull cables from the sensor to the main unit

By far the easiest thing to install on my 09 Vision. with one caveat. Check your OEM oxygen sensors to see if you can remove them. The rear sensor on my 2009 Vision is stuck. I had to go to EBay to find a replacement transom head. I like the positive locking cables from the sensor to the main unit. The cable length is more than sufficient for most concealed installations, allowing your mount to auto-adjust within 8" of the PCV. Interconnect, autotune to PCV, the cable is terribly short. Planโ€ฆ

Pros
  • Two o2 sensors included
Cons
  • There are new competitors

Works great, but no plugin!

I have a 2007 Victory Vegas. I have fitted different deflectors on the outlet and inlet Lloydz torque tube. I had a hard time finding anything close by to get my hands on a dynoed bike. This device was exactly what I needed. I had about 3 maps to choose from that were available from the Dynojet. None of these three had an AFR table to choose from. I had to manually adjust the AFR chart, which requires an understanding of the fuel/air ratio. But the device works very well. It's not a plug-inโ€ฆ

Pros
  • Control module with 2 sensor inputs
Cons
  • Crumpled packaging
