Many thanks for posting this video. I have the identical bike to yours so won’t waste my money on this product after reading your review.

I bought a FZ6S and it came with a powercommander in a box (not installed). The throttle was horribly snatchy, so I installed the power commander and loaded a map for aftermarket pipes (has leovince exhaust on it) and the throttle response was day and night different. Buttery smooth and no on/off jerkiness. I can putt around at low speed no probs, and no longer has the scary jerk when you cut the throttle entering a corner. Also bike runs slightly cooler (prob because its running richer now)

Hello @piggypower ! I've been reading all the comments and information you've left for a while. I have had an S1 for more than two years and from the first day I realized that the response of the motorcycle was not normal. You are probably the person who has tried the most things and has been most involved in trying to solve the problem. So, thank you for your work and try to ignore people who don't know what they're talking about... it's a real and common problem in fz6. Without being disrespectful, I would love to know whether or not you have finally been able to solve the problem, knowing that it is 100% injection and I support you with it. I have been trying to improve the response for a long time and today I can only increase the idle speed and notice a brief improvement. Kind regards.

I fitted a Booster Plug after reading the reviews. I fitted it very soon after getting the 2009 FZ6 so didn't have much to compare it to. I did notice worse fuel economy by about 10%. I have used Fuelly since day one and so have all of the data from every single fill up with the FZ6. Having seen your review I have just been to the garage and removed the booster plug. I've got a 120 mile round trip planned for tomorrow - most of it motorway but it'll do - so I can get a fairly decent idea of the difference. The main thing that annoyed me was the wrong ambient air temperatire being shown. I don't know why it annoyed me, but it did. So, all back to stock standard and tomorrow will be the teller.

Your video is one of the first I watched for the boosterplug and sorry to hear it didn't work out well for you. But I think I have a suggestion for why it didn't work too well. I remember you put the air temperature sensor next to an intake, which would be covered up. It needs to be put where it is not covered up and exposed to open air. I think that's why it didn't work well for you. All other videos where they rave about how well it works it's put somewhere towards the front of the bike where it will be exposed to open air.

I bought one if these and didnt noticed much change on my AFR sensor (in fact the mixture was barely changed). I opened the booster plug up and its simply a resistor that has the temperature probe going across it. Very basic unit and nothing like the 'clever' unit they suggest it is.

I have an 07 fz6 and G2 Throttle tamer helped me with that problem. I also added larger cushioned grips to increase the diameter.

Try taking the exhaust and cat off and go for a short ear deafening ride to see?

Put the sensor in front of the rad.

Did you figure it out? Any update?

Hey @PiggyPower I'm eager to know the results with the power commander. Any news? Check 600riders i've been following your thread ;)
