This looks like a infomercial piece, could it be real?

I stumbled upon this today. It reminds me of an " As Seen On TV" thing. The way i read it, it is very comparable to the power commanders. Does anyone have experience with this product? Does it correct for intake and exhaust changes? Kind of looks gimmicky to me. Your thoughts. https://www.boosterplug.com/shop/boo...tard-350p.html

It basically plugs into your temperature sensor input and tricks the computer into thinking it's really cold out. When it's cold, you need more fuel because the air is more dense. This will combat the issue of the bike running lean in order to pass emissions.

Just one problem... our bikes also have O2 sensors that keep the bike in closed loop from 0-20% throttle and 0-6000RPM. So the bike will adapt to the perceived temperature change and you'll be right back where you started, except with a richer open loop (high RPM high throttle opening).

It is not like a power commander at all, because with a power commander you have complete control over every RPM and throttle condition. Sadly though, our O2 sensors will also cancel out a power commander in the areas that really matter, around town!

So, basically it's a joke? I noticed that my dash temp (the one for ambient temp) is always claiming it is warmed than it actually is. I believe I remember you doing an in-depth detailed test on some controllers(I may be mistaken). I need to go back and look that up again. I stumbled upon this and thought it was too good to be true.

It's not a joke, it could work on some bikes. It's kind of a band-aid and definitely not optimal.

boosterplug works, i have one at home and used it for about some hundred kilometers.
it tricks the temperature sensor. you can proove that because temp always reads 20C less than real temps. so it always richens up fuel ratio. this works fine, bike runs better, also or specifically in closed loop. it runs much smoother than stock, but it also richens in open loop, where mostly it's not neccessary and only wastes fuel.
I bought it to try because its rather cheap and easy to install.
but, my 939 used about 1 l /100 km more fuel (about 20%) than without plug, that was too much for me, mostly becasue of the reduced range.

i have a rexxer evo now and bike runs as smooth as with boosterplug but does not use more fuel than stock. only negative about rexxer at time - they cannot disable o2 at time with 939 Euro4 models.
my Euro3 821 run even better and smoother with rexxer because of o2 disabled.

If you don't have O2 you get to run richer and you get to look at christmas lights on your dash.

not when it's disabled in your ECU, what Rexxer does.

You can try how it runs without o2 regulation by simply disconnect O2 sensors.
It runs much better, but with yellow engine light, thats right. Thats exactly the reason why it has to be disabled in ECU.
In IAW5 ECUs you can disable O2 with JPDiag or GuzziDiag (IAW5Writer), unfortunatly not with our IAW7SM ECUs, so you need someone who has cracked the IAW7 ECU.
But then it runs without O2 and without engine light.
