Any device that fools the ECU is crude and wrong in my opinion. I also do not advise anybody to tune their car that way.

It is the customers choice whether they want to tune their car via fitting a device that fools the ECU or whether they want a flash remap or a custom flash remap.

I did post my advise and my opinions on this thread of products and how they operated. I did not come on here to slate the names of companies.

To the OP, what have you got to loose by trying it? You try it, if it does what's advertised then great.. If you don't like it you return the thing and get your money back. Plain and Simple...

Me I'm testing a tune for Terry on my N55 X5, Terry gave it to me Gratis and I get the added power, and it works as advertised. I can dial up or down the power how I see fit, and if I push it up to much of course It may cause damage and who's fault will it be, MINE, not Terry's and definately not BMW's.

I owned a Procede V4 for my 335xi when I had it, and that worked as advertised too... Never had a issue at the dealership (tuner codes or anything) and it definately provided a boost in power.

So I've sampled both major piggy tuners, and they both do what they say there products will do.

To Aidan.... I suggest you try the product before you knock it. It may just surprise you. And like I said to the OP, if it doesn't work for you, return the item, get your money back. Don't believe you wont get your money back, that's your problem. But they are a pretty well known company here in the states.

As for Kloogy's references to lucky charms, or drunk or whatever... I say whatever... Everyons entitled to their own whims, comments and opinions. As long as its not offensive.. I personally don't find it offensive, but then again I am neither a drunk or Irish, so my opinion on the matter, matters not.

Just my .02 cents... Take it or leave it, matters not to me

Where did I say they have CARB certifications ? I mentioned that if anyone here has ever dealt with having a product approved through CARB, that they would see the cost of doing such a thing. I know because I was involved with a company who designed a product for Mustang Modular motors that does have a CARB certification. It was a fancy way to say " Bribe the State of California to the tune of thousands of dollars to give you a sticker "....That's all I referenced. I don't think any of these guys have CARB numbers. If they did, the 400 tune would be 1200 bucks. I'll call him Lucky Charms, a drunk and anything else I want because he is irresponsible enough to attack a company without knowledge. If he were just giving his opinion, that's a different story.

I never attacked the name of any company. I give my opinion on how tuning boxes work. What part do you not understand?

To call me stupid names is plain silly and makes you look like a childish fool.

You are the one who brought up the cost of CARB certification when you were justifying product development investment by aftermarket parts vendors. So if you weren't implying it, then it looks like you were obfuscating. Why else would you bring it up when justifying BMS's sales price.

You are focusing on whether he is attacking BMS. I never thought he was, perhaps due to my prior knowledge. I thought he was classifying all piggyback tunes as crude. Some are much more crude than others, obviously, but they do all fool the DME/DDE in a manner of speaking. That is the concept he was putting down, he doesn't know anything about BMS AFAIK. And it was obviously his opinion.

I think you should reconsider your plan to attack people you don't agree with. It is not acceptable to call people names because we don't like their positions. Discuss the idea, not the person. You should reference the forum rules in that regard:

Buddy your not fooling anyone, everyone reading this thread can see that you are clueless on the subject matter. Yes there are resistors in the picture, but the JBD does not work by just resisting! For example PC's have resistors but it don't mean it's just a resistor.
Do me a favor build yourself one of these "resistors" and hook it up to your car, then tell me why it didn't work. Maybe it's because there is more to it than just resisting!!!
Read post #99 you'll learn something from it. It's funny how you have replied to all the other posts except for #99. I and many others would like to see what you have to say about it.

I disagree. I believe what I have done on this thread is opened a can of worms on how tuning boxes work and what they are crudely doing to the engine control unit (ECU)
Once again, I will explain to yourself, yes you that has difficulty with reading what I have posted, the tuning box alters the signal going to the ECU. In other words THIS IS FOOLING THE ECU.
Does that make me clueless?:rofl:

I do enjoy when new members are just signing up to jump on the bandwagon here,,, hmmm I wonder where they called for:D



I have nothing to reply to post no.99 as Terry has admitted that the cheap money makes these tuning boxes.

My points where: IN MY OPINION
1) The tuning boxes release extra bhp from the engine in a very crude way
2) The ECU is been fooled into thinking the fuel rail pressure is insufficient so adds more fuel
3) The tuning boxes can be made for very little money. There is a Huge profit to be made
4)Tuning boxes resist alter the signal going to the ECU

********
:popcorn:Ok I will grab some more popcorn, bottle of coke and some chocolate while I wait for New members to join this forum, to hop onto the bandwagon and call me clueless and tell me that I am slamming the names of companies etc.. *******************

Ok this thread has too many kids in it. I am getting a bit tired with it now;)

Tuning boxes = Alter the signal going to the ECU
Why Do I not rate them? Because all they do is fool the ecu and release extra power in a very crude way.



^^^^ I suppose that is still to complicated for some of the people from this thread... Yea I am clueless lets start that again:bustingup

Does this sound familiar?? LMAO!! Again proves how much you "know"
