Another member posted this in the Canada forum so I copied it over here. I'm highly skeptical and doubt it works, but wonder how people can get off selling this and what exactly they claim it does to increase the HP??


The Juice Box

Has anyone heard of the Juice Box? It promises increases in horsepower but a search for Juice Box on the forum turned up empty. It sure looks like a cheap way to increase HP but I'm skeptical about quick fixes like these (warranty, insurance, etc.). Your thoughts are welcome. Thanks.

Fixed now!

Reading what they say...

We guarantee The Juice Box Power Control Module will outperform any other Power Control Module on the market for under $179.00. In fact, we're so confident in The Juice Box that if you find a better performing Control Module for under $179.00. We'll not only refund your purchase price, but we will also pay for the other Power Control module!
So, this means that you can't find another wonderbox under $179 that would perform better than this... which is true because there is no PCM piggyback unit on the market that would cost less than $179.
No matter what, anyone who will buy this will just waste money, i have no doubt. Ah well... there will always be plenty of gullible people who will fall for things like this.

But what the hell is it? I'm tempted to buy it just to rip it apart.

You know what... I can also sell you a black plastic box, with "The Juice Box" written on it and a couple of wires dangling... it's all yours for, let's say, $25. Deal? :D

Tamas, that is too good a deal. I'm tempted to buy your box and take it apart to see what is REALLY inside.

Hell I'd love to get ripped off on Ebay for such a small amount, I'd rip the jerk to shreds. Plus he's got positive feedback?????? I dunno, curiousity sometimes gets the better of me.

Hey, don't let us stop you :D

Does anybody actually know the theory behind this idea though? Like how is it even possible to give you extra horses? I know very little about cars, I just like them a lot...

Check out the threads in the Canzoomer vendor forum or just search for "canzoomer" or "eManage" on this board and you'll have plenty to read for awhile.

Here's part of the Q&A that I just copied.

"Where does it hook up?"

"You can use your Intake Air Temperature sensor or your Coolant Temperature Sensor"


This product is just a resistor inside a box that connects inline by splicing 1 wire. It fools the ecu into thinking the car is colder and this makes it run richer. The RX-7 and the RX-8 both run RICH from the factory. Adding more fuel will not make more power. Someone paid $28 buy it now and then is paying $6 for shipping. The most expensive part of this thing is the fancy plastic box. The resistor was a few cents as were the wires. He might have paid a buck or two for the box. That's a healthy profit for something that will make you go slower! If you find a car that runs lean from the factory then you may in fact find a car that this works on. There is nothing magic about it though. You can file this in the same useless parts box as the K&N cone filter kit.
