Started to google.

FW was 1.8.5, now I updated FW to 1.9.2. I hope this will end this story. Will update.
It was working well one month after FW update. Even did one fast pace track day with it. No problems.

Having big issues now. I washed my bike this weekend and after that it has not run well. Immediately after wash I got Code 11 (Throttle sensor). I warmed up the engine and the Code did not appear again. Next day, same thing when I started the motor, Code 11. After 5min idling Code was gone.

After these two days I have not seen any Codes. Still my bike is not running well. This morning on my way to work, constant cut-offs, not just "burping" losing one cylinder, but I loose all power. Could drive like 40mph max. When gear is in neutral it revs fine.

Any ideas? I can try to downgrade to 1.6.10 today. I can open everything and check connections. Could water in the TPS connector cause this? Could loose gear position sensor/connection to PC5 (that one you need to splice) cause this?

Edit. downgraded to 1.6.10, did not help. Still the same. Need to dig into the wiring tonight.

Power commander firmware

I had this problem a couple of years ago and removed the PCV. I have booked my bike in with a really good local tuner and he is going to install it and Dynotune it. The latest firmware is. V1.10.6. Has anyone tried it. It was last updated on 1/6/2013 so I hope it is good. Thanks

Dropped bike off for custom dyno......Delivered to shop with damn near 900 miles on it after a few weeks of putting on heavy miles with latest firmware no issues (knock on wood) Will have dyno done on Thursday and will take some long rides after that, Will post in here again after a few thousand to confirm no issue.

Well for the sake of anyone wanting to know if the latest version firmware is still confirmed to work I feel pretty confident to say it does. Over 1,000 miles on my bike and she's good. Dyno was done last week put on about 200 since then and still good.

I did a track day today on the latest firmware. The bike ran perfectly.
