Any 35D Owners install this performance tune?

[tlouie]

Well I installed th JBD at 1225 miles and now am at 2500 miles....not alot of time on it, but here are my observations:

Definately more mid-range power...especially from 3-4k rpm, butt dyno says maybe 40-50 hp more, i'm running th JBD at the default halfway setting...who knows how accurate my butt dyno is, but its significantly faster as my passengers can attest

I dunno how accurate the onboard computer is but in the drive from home to work my car was getting 27mpg, and now the onboard computer is telling me an average of 31mpg...this could also be the car breaking in more and losening up

I've never had any kind of CEL or other warning, but then again my JBD is set at the mid-way setting, higher setting may cause CELs

Looks its $325, what did you expect for that price? of course you are not getting the most sophisticated tune, then again a $5 bleeder T on a supra MKIV adds 50+ hp....really crude

Thank God this has finally turned into a mature type of technical debate

Firstly, I was merely giving advice regarding tuning boxes. I did state that yes they do their job, they do release more bhp but in a very very crude way.
It is up to you if you want to buy one and try it. Do I advise them? No I defintaley do not and think that 300dollars could be better spent on other performance mods.


Moving on, I am likely going to get slated once again but if you don't appreciate my advice PLEASE don't read it or don't leave silly comments quoting my posts. It is very dis respectable.

So I read few pages back that somebody mentioned a certain company that offers a warranty.
This is a played out sales gimmick I often see over here on this side of the world.
Example: Your turbo blows after 6 months.
A remap is detectable there is no question about it. Even though no components are added, if BMW decide to run a live reading from the OBD they can compare the logs with a standard original file and note some differences. What happens next?
BMW tell you your ECU settings have been altered and your warranty is void. Next thing to do is call your "tuner" and explain to him what happened. Now here is where the tuner has you where he wants! He is asking you to prove that the malfunction of the turbo is caused by his remap. You can travel all over the world to all of the various engineers and nobody can prove that a remap caused the turbo to blow. Yes they can guess but not prove and proof is what is needed. BMW cannot give you a statement to say that the turbo failure is a direct cause of the remap by that tuning company BUT they can void your warranty so they can basically brush their hands of the problem.

We do what we can.

I don't think it is fair to lump all tuners in the category of shysters and thieves. I am also sure that there are some (lots) in the business.

Dinan is a different situation, IMO. They also charge a lot more, but their past relationship with BMW allowed them to get close enough to come up with a supplemental warranty. It isn't cheap, you can get more power for much less elsewhere. But it is safer than some unwarranted options out there. Even more so if you buy and install your Dinan products at your selling dealer. That puts your dealer in the warranty claim loop to both Dinan and BMW, which can work to your advantage.

TMS, selling the JB and JBD, is also in a different situation. They don't pretend to offer a warranty, and they are very clear about it. If there is a problem, it is your responsibility, not theirs. They don't meet emissions requirements. Their tunes are very cost effective. They are not shysters IMO. They take a low-tech approach, in that they don't worry too much about a check engine light, they just provide a tool to clear it if you get one.

Then there are the low buck outfits that claim all sorts of things, including that their tunes are not detectable. BS.

I just don't think that all of the above can be put in one group.

Let's not beat around the bush. Why don't you mention some names. I'm curious as to who you would lump into each particular category.

There are far more vendors than I can possibly know or have an opinion on. I can evaluate warranty and non-detection claims by various vendors. I haven't got any experience with the validity of the hp claims by various vendors, only what I read. My dyno days were way back.

I think Dinan is reputable, and I put some value to their warranty. I also think they are expensive. If I wasn't buying Dinan from my dealer, I wouldn't put so much value to them, because I wouldn't want to deal with two different dealers who could split the liability in the event of a claim. I put Dinan in their own category.

I think BMS is honest about what they are doing. For those that want hp for low $$, they seem to have a following, and they are honest about their warranty. I put them in the honest and cheap category. You get what you pay for.

I think the Procede is a more elegant solution than the BMS products. I think it has more engineering in it, and a better approach to things like safeties. That costs more money, for around the same hp. I think it is worth paying for more engineering and features. I also think that Shiv, while talented, can be quite blunt. How is that for beating around the bush? I put them in the honest and more expensive category.

Who else do you want to discuss? How about if we put all of eBay in the shyster category, until proven otherwise?

Sounds about right. Procede still claims that it cannot be detected by a dealer. Biggest mistake anyone can do is taking their vehicle in with a DCI clearly starring the SA's in the face. That is a clear alert sign that says " LOOK AT ME".... I would make sure to take it off, or not even put one on.

The OBC is not expected to be accurate with this box installed. It is a documented side-effect of the box fooling the ECU. If you are measuring from tank to tank, and calculating manually, I would be interested in any improved fuel consumption. Unlikely though, as it takes fuel to make power, and if you are noticing more power, you are burning more fuel. If you aren't using any of the increased power, you wouldn't burn more fuel, but then what would be the point of having the tune?

was there any result from tank to tank fuel consumption?

You are responding to a two year old thread, and most of the posters on this particular thread came over from other boards to have a debate about one particular tuner. They left en mass after the drama died down.

It is a valid question as to whether actual (real world, not OBC) fuel consumption changed after any particular tune, but it would be better to start a thread with that question, IMO.

JCL...i understand...

I'm justing dying here reading all 10+ thread to find out an answer if this thing has timing advancement...

from little i know, from the Eprom tuning, back in the early 90s, they do claim a fuel efficiency. I will go ahead and start another thread in regards to your suggestions. thanks!

Howiedds,

I get it about the right foot, and right wrist (i own many motorcycles as well) theory, but, in nature, does this mod gives a better fuel efficiency?
