ADVICE NEEDED: Idle Surging and PowerFRK
Sorry I have been gone for some time. My 2007 K1200GT has been sitting for a long time at the dealer after my accident. The dealer claims that they have been starting it weekly and keeping the battery charged.
When they had the tank out many months ago, I asked them to plug in a PowerFRK that I had bought in 2009 but never used. My goal was to smooth out throttle response at low speeds, such as in a parking lot.
Now that it is ready, the dealer tells me that the bike is not stable at idle. It surges up and down, up to 2000 RPM, down to below 700 RPM, and has stalled twice on idle. The tried flashing the ROM on the bike, but it did not make a difference. (The airbox was replaced under the recall in 2008.) Of course, the dealer wants to blame the PowerFRK.
I called Robert at PowerFRK USA, and he swears that the problem is not and could not be the PowerFRK. He says that the dealer should check the oxygen sensor. If it not the sensor, then he says that the ECU has been flashed one too many times. (I told him that it has not been done much, but he says that the dealers often flash the ECU without telling customers, just to make sure they are up to date.) Robert claims that there is a "silent recall" on the ECUs that have been over-flashed, saying that they repeated "hunt" (RPM not stable).
Robert says that if the O2 sensor is good, then I should send him the ECU along with a few hundred dollars. He says that he will wipe the ECU and flash it correctly, not only solving the problem but also mapping the engine for superior power and performance. He says that his work will not interfere with my GS911.
The dealer is waiting for an answer from me. What would you recommend?
