Any 35D Owners install this performance tune?

Very valid observation.

I was alluding to some of this in my references to the e90post and n54tech forums. The various tuners and their customers tend to have strong views. That debate has just spilled over here. We have customers of BMS here, a tuner that does a lot of business with piggyback modules. We have a tuner from the UK that is promoting a different approach, using a new map instead of intercepting sensor signals and spoofing the ECU. Both approaches work.

IMO, the debate is better without the personal name calling that began.

People who are interested in increasing the power of the 35d engines and are just learning about the different approaches, the warranty implications, the ability of BMW to detect modifications, etc, can have a hard enough time without the heated rhetoric.

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.


.

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.

So you're going to validate this guy as a legit " tuner from the UK "? If he's a tuner, I would be afraid of what he would to my vehicle. FYI, I have not purchased anything from Burger, or any other tuner. My E60, E92, and now my E70 have not been modified with a tune. So if you are implying that I am shilling for a certain manufacturer, you are very wrong. What I do see is someone coming in to defame a company and it's product. Someone who obviously has very little knowledge. That has been already exposed by the erroneous statements that he has made.

It's wrong to lump any one of these companies mentioned so far, with Ebay tunes. This guy thinks because the breakdown of the cost of parts is 40 bucks, that the company should charge 45 bucks for it. I don't know how the economy is in his land, but in the United States we are firm believers in capitalism. Companies put money into research, testing etc. Ask any aftermarket company that has had to have a part CARB certified in California, how much they spent. If you are willing to come on a forum and make irresponsible claims, then I will call you what you are. If you don't like it, too bad. I bet the companies that have sunk thousands of dollars into developing these products don't appreciate being called Cheap Ebay Tuners.

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

I proved my points. Please tell me how I have very little knowledge?

I did not come on here to slam a company but yes I will admit that I did come into thread to slam tuning boxes that resist power signals going to the ECU and I will always slam them as they are very crude method of tuning in my opinion.

Let's look at your original post :

They are renowned for causing ECU failures, CEL lights and Limp mode.

So far we have proved that this entire post is WRONG. "They" are NOT "RENOWNED", for any of this.....on ANY forum. Unless you have some secret society that is reporting these things to you, please make an adjustment to your original post.

I think the illumination system on it has resistors on it, it must be cheap Ebay stuff !! I wonder if BMW in a wild scheme to produce cheap ebay stuff, used a resistor anywhere in my X5 ????? OMG !!!!!

Please stop posting pointless un-constructive junk, they are not even funny just annoying to read. You think that because I am in Ireland that I am drinking scotch while posting, you talk about leprechauns and this Lucky Charm name calling crap,, please do get over yourself and grow up a bit.

I give my opinions on how tuning boxes work and their crude way of raising the fuel pressure and you jump on the bandwagon stating I have no knowledge.

To generalize tuning boxes then yes they are renowned for it and no i will not adjust my original post. I have seen countless cars billowing black smoke, cel lights popping on, limp mode cutting in, ecu eprom glitches all due to the ECU been fooled.

I called him a tuner. No comment on legitimacy, qualifications, or anything else. I have nothing to evaluate him on other than these posts.

I don't think you are shilling, as I don't know your relationship with BMS, so it wouldn't be a fair charge. I think your own post on the BMS site portrays your position quite accurately, something to the effect that bad people were saying bad things about the BMS products on another site (xoutpost), and that Terry needed to give you a picture so that you could shut it down.

When you tried to get me to rate the vendors, I commented on three of the better known ones, and said we should lump all the ebay sellers in a separate category. I thought that was quite clear.

I think it is misleading to suggest that these tunes have CARB certification.

What I have observed is that promoters and fans tend to get quite excited about these sorts of products. For another example, just read about Sprintbooster here or on many other forums . In the case of Aidan, he apparently thinks of tunes as either remaps, or something much less than that, and he lumps all piggyback devices together. That is his prerogative. I don't happen to agree, but I don't see a reason to start calling him names. Calling someone Lucky Charms reflects on you as much as it does on him IMO
