Any 35D Owners install this performance tune?

Our buddy kept claiming all we would see were 2 wires. That's what was being disputed.

I think you do take too much sugar in your cornflakes in the mornings.

I claimed that you will find a resistor in the box and guess what I see in the photo Terry posted? 2 resistors!

So what is in that box?

2 RESISTORS.

There is a huge 28 pin chip in there also. This is used to allow for adjustment of the variable resistors.


Now to close on this one, as I have proved my point that those tuning boxes do is RESIST the signal going to the ECU I have typed up a paragraph on what I think of tuning boxes and this is my opinion on them. Yes I will generalise all resistor type tuning boxes as they can all be made at home with all the parts purchased from ebay for less than 30 or 40 usd. If you were buying them in bulk they would be much cheaper. Definitely a huge profit margin in them.

Tuning Boxes in my opinion.
Tuning boxes are the mother of all evil in this world of tuning. I am sure they were developed in a secret facility by satan himself and that is putting it mildly. With ECU remapping you change ALL the needed parameters that run your engine. A tuningbox just lies to your engine management system, throwing it off balance and feeding your engine the wrong amounts of fuel etc. Very often you will see powerboxes on ebay, which are basically two plastic plugs, a small box and a 5 cent resistor poured into black resin. Some of the more advanced ones will have 2 resistors and a chip to allow it to be adjusted, adjusting the power of signal going to the ECU. If you want to get rich quick with an astronomical profit margin you should start selling tuningboxes, because the company logo sticker on the outside is the most expensive part of it. Do they give you a noticeable effect? Yes, you will get some more performance, accompanied by a tail of black smoke and an engine that hates you forever. Still want to buy a tuningbox? Read this paragraph again.

I hope no one on this forum takes you seriously. You have no idea what your talking about. STOP comparing stuff on eBay to the products that reputable companies like BMS offer. I've been using a tuning box on my car for about 40,000+ miles and no black smoke, no issues, no nothing! And I have pushed it to the absolute maximum. Just like many others have done the same.
The Internet is your friend, do your homework before you run your mouth. There are many many people on these forums that are very very knowledgeable on this subject that will not hesitate to tare you apart and prove you wrong. Just like we have seen here.
As far as your argument on the resistor thing, well it shows how clueless you are about the subject .

What is your problem haha! The tuning box is placed in on the fuel pressure signal going to the ECU. It is fooling the ECU that pressure is lower than what is really is THEREFORE the pressure is raised further and thus making more power.
Now people on here think that is some impressive tuning eh? And you call me the clueless one?
So many Keyboard warriors on here!
Can you not look at the photo and see the resistors! Why are you calling me clueless when they resistors are there in the photo

I have seen here there are so many people on this forum that even though they know they are wrong by saying that I am clueless when I explained and what was proved by the seller what is inside the tuning box and how they crudely work and how much they cost to make! Please tell me how I am clueless

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?

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



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

********
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.. *******************

I don't know why I am getting involved in the "discussion." I guess I just have nothing better to do while sitting at work . That being said it amazes me at the ignorance present in this thread. Several post on this thread come from 1st time posters that joined this month, and are very actively defending the BMS JBD....coincidence, I think not. I am not bashing the product by any means, but if someone is worried about longevity and reliability they should stay away from ANY tune not just the JBD. Aiden has provided some good first hand technical knowledge (however generalized you want to say it is). Whether you agree with him or not, unless you have evidence to prove otherwise, take what he has said for what it is…his professional opinion based on experience. I am no expert on tunes and do not claim to be, however the JBD is essentially a variable resistor with an algorithm which does fool the ECU to increase the fuel delivery (as Terry stated himself) to increase the power. Yes it is effective as the 200+ users of it will attest to, but the potential damage to the motor and driveline components is not yet known. If you are okay with taking the gamble, then by all means purchase it and be happy with your decision. I have no doubt you’ll experience increased performance as with all BMS products. Personally I prefer another company for tunes, but they haven’t released a Diesel tune yet and I’m not sure if they plan on it. As far as Kloogy and any of the other users bashing others post without offering any technical information to prove otherwise, you’re wasting everyone’s time on here. Bashing someone else when you have nothing to counter with and provide something the OP can benefit from is a waste of everyone's time following this thread. Grow up a little and stop whining when you aren’t technical educated enough to offer any useful information towards to thread. It’s real easy to sit back and complain about how wrong someone is, especially when you can’t articulate why they are incorrect. Ok I’m off my soapbox now and maybe will leave room for someone much smarter than me to offer something constructive to the OP. No I have to try to do something productive enough at work to feel like I've earned my paycheck today.

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

.

The recurring JBD manufacturing costs are around $40-50 USD in lots of 500 with much of that the full pnp harness cost. No one claimed it was expensive to produce and anyone can simply add up the component costs. If you do this for a lot of your favorite electronic items you'll be surprised how inexpensive they are if you only add together raw parts. But beyond the recurring costs there are thousands and thousands of dollars of expensive engineering time designing the firmware and months of tuning time to determine the appropriate algorithms to obtain a safe, reliable, and improved 335D/X5D tuning. The box itself is just a medium to implement the tuning.

The "chip tunes" sold on eBay, etc, are generally around $5 to produce, they are sold to suckers for $20-$50, and they do absolutely nothing and include no pnp harness just two wire taps. Those are truly a resistor in a box requiring the suckered purchaser to buy in to this concept of altering the IAT signal to remap the car. Which is nonsense. In fact BMWs compare ambient temperatire to intake air temperature during cold start diagnostics so in addition to no performance you'll also get a nice check engine light and limp mode until you remove the device.

Also on a personal note I think you just don't understand much about electronics. The DME analog signals largely works on voltages not current. "Resisting" signals will not have any effect. You must remap voltages to obtain the desired results and those changes are not linear (e.g. not a simple voltage divider). In fact to avoid BMWs tuner detection system with the JBD we have to do some pretty strange things with the signal. It starts out as an OEM signal, then alters itself at times, but during other times reverts back to the stock signal. Good luck doing that with resistors.
