Target Tune Problems

Last fall I installed A new PowerVision, Target Tune, Fuel Moto Jackpot stainless ceramic header, Vance & Hines HighOutputs on my new CVO. It ran awesome. Since then I have only ridden about 1500.

Two weeks ago on a local ride I noticed the bike felt sluggish almost like I got a bad tank of gas. Temp outside was mid 70's low 80's. Sitting at stoplights the bike felt like a pogo stick.. Vibrating really bad and sounded out of sync. Took the bike back home and checked to make sure nothing had come loose. Also checked over wires going into the TargetTune and 18mm 02's. Everything was secure. I set the gauge screen on the PowerVision to monitor AFR. Everything seemed good, AFR indicated was was in the map.So I decided to run an autotune on the Target Tune map provided by Fuel Moto. That really didn't help. It took some of the vibration away, but not much. Bike still sounded off. I decided to drain the fuel in case I got a bad tank. Went and purchased a new fuel can and 93 octane. Dumped that in and ran the bike about an hour, still no better.

I decided to remove power connection from the Target Tune and connect the stock OEM 02's. Flashed the base map provided by Fuel Moto and started it up. As soon as it fired it sounded night and day different. Bike sounded angry with power. Cracked the throttle a couple times and bike responded instantly. Then took it for a ride. Basically felt great! No more pogo stick at the stoplight. Since then I have run autotune based on Fuel Moto stock map. Feels like a new bike!

Anybody else running into problems with Target Tune like this?

I have the TT ... No issues to report to date.

Did you purchase from Fuel Moto? If so... Give Jamie Long a shout.

Not sure how to check them but maybe a bad O2 sensor?

Thanks Spazz for the info. I did purchase from Fuel Moto so I will try to give them a call tomorrow.

One step I didn't capture above prior to disabling Target Tune I performed the 02 condition test that that is in the Target Tune installation guide. The system checked out as "normal" for Midwest (700' above sea-level). Posted a couple pics of my install.

The Target Tune kit has a built in function
which allows you to test the sensor accuracy and condition.
1. Remove the sensors from the exhaust system and
hold in ambient air.
2. Verify the Target Tune kit has been powered up for
at least 1 minute and has a solid light.
3. Press and hold the function button on the front
of the Target Tune kit for 3 seconds to initiate the
test on sensor #1 and release the button once the
light begins to blink rapidly.
4. The LED light will blink rapidly, pause for a
moment, and then begin to flash a series of long
blinks before going back to solid. (You may get
zero blinks before going completely solid, which
would indicate a perfect condition if at or near
sea-level.)
5. Count the number of long blinks and refer
to the chart.
6. Initiate the test a second time to get results for
sensor #2.
7. Retest the sensors if there is any question as to
the purity of the air during the test.

Set up a gauge page to show the front and rear O2 sensor voltages, and also front and rear AFR. After leaving the bike sit overnite, turn on the ignition without starting the bike and look at these numbers. If there's a problem it shoudl be immediately obvious. For that matter, any time you look at the these readings they should be very close to the same front and rear at steady engine speed.
