FYI: JB4 & integrated Meth from BMS $1k - mighty fun; better than any Dinan, the latter premium priced throughout the line. Running, what, ~450 hp & 450 ft lb torque....heck I don't even know. Runs sweet, so, hard t'care!

My Volvo S70 has 195K on her, does that count in gas years?
Oh yeah, my vinyl seats need replacing too!

Two quick things.

Dinan effects 2000 lines of code in the ECU BMS effects 0 lines of code in the ECU. The ECU code remains stock just the same as the day it left factory. Pure stock factory code in the ECU makes me comfortable.

BMS has over 15,000 installs with no screaming mobs rushing to burn down Terry's shop over blown motors or other damage to the cars. IIRC the two main shop cars both have over 70,000 miles on them with no major failures. The 135i's auto transmissions is starting to go & was slipping at 160mph+ during some 1/2 mile airport runs.

Well- Dinan has been an accepted flash from mother corp. BMW. I had mine done at the dealer..you?
Your stock code leaves you in a comfort zone even though only the one main parameter has been affected-yet mine has BMW's blessing to a point-(I get it)- to change other parameters.
Look at the BMW performance package-it was also more than just a boost. Do I think you are going to suffer for not changing other constraints? No. Most likely not.
Again, we all have choices-for my day to day car-I chose a conservative-yet lively ecu flash. 60 grand is not the be all and end all for me-but it represents a fair bit of disposable cash for sure!
A warranty for the first 4 years was a must for me. Hey, that ends soon-who knows, may be I'll buck up the ecu a bit more then..
No wrong choices here-just different ones, inmo.
ps, your sig shot? what do you fly?
Cheers,

Its an AT6. Not sure what you mean by just one parameter with JB4? The log shows things that are being tracked & forwarded by the JB4 system. For space reasons things like fuel pressure, inlet air temperature, barometric pressure, waste gate duty cycle etc. are not shown

All I found at Dinan with a quick look was this:

The biggest difference between a true software tune like Dina's Performance Software and a "piggyback box" is that all of the communications between the engine sensors and the engine management computer (DME) remain unaltered. This translates to properly returned fuel mixtures, Ignition timing and full map rescaling to keep everything in sync. I expect there may be more but this looks to be their key points

The piggy back side of that is the ECU remains unaltered but the signals from the sensors are intercepted & converted to something the ECU expects to see & the ECU goes about its business.

A few things I think might be an over reach. BMW USA does not accept a flash from Dinan. With a Dinan flash your VIN # is locked & the car cannot be CPO'd. The Dinan warranty runs in parallel with BMW so Dinan will pickup anything that BMWUSA refuses to pay. The fact that a dealer does the install does not place it high on my "that's really great" list.

There was a time a number of years ago when BMW did have a closer relationship with Dinan but it was terminated by BMW for reasons unknown to me & is now strictly a dealer aftermarket service like any number of other thing they sell like nitrogen for your tires.

You say that as if it is a bad thing. Transparency is a good thing. No one has really addressed my point that one of the selling points is that it is undetectable. I could very shortly pull up 50 threads where the main point of discussion is "Can BMW tell I modded?" "How do I clear the codes so BMW won't know I modded?" "I am going to take off the mod before I sell it so nobody will know." Shouldn't a later purchaser be entitled to know that the car he is buying was modded and driven like a rented mule? Why should consumers pay increased costs in the form of higher purchase prices because people choose to try and get BMW to pay for their fun? It's not apples and apples because it is a major safety issue in a plane, but wouldn't/didn't you want to know exactly how the prior owner treated/modded the engine on your plane before you bought it? Again, not saying you fall into this category, but so many do.

Software upgrades are free and downloadable via the USB data logging cable. However, hardware upgrades are not. For example, the G5 board that just came out for the JB4 is something you'd have to purchase and is not something you can download. Also, if you have a JB3 and want to upgrade to the JB4, there are additional hardware and costs.

I have never fully understood the animosity towards Dinan on this website, most discussions tend to end like little children fighting in a sandbox. It's my observation based on reading many postings here it's not a Dinan user that usually starts the confrontation, but they feel compelled in defending their Dinan choice ergo it escalates from there.

As far as who's best, PLENTY of postings to read between the lines and get a pretty good understanding of what's what.

Dinan has been in business for a long time, many modders that have followed have done some nice work, so wtf guys, we seriously need to get over this Dinan bashing and just enjoy!
At least till I pull up next to you and...

Cheers,

Yeppur....so very accepted that BMW terminates its warranty if installed.

So, you have Dinan's warranty.

About dealer install....have you noticed Dinan is purchased at a premium vs competing tunes? They cut a deal with BMW, famously known for doing nothing without showing a profit. They are paid to endorse.

Dinan's well known, and beyond argument, for providing lower performance than JB4. That slight-o-hand, crank vs wheel, is the marketing result. Simply, you pay more per hp & ft lb than JB4. Significantly more.

And push come t'shove, Dinan just doesn't have the juice. Literally - she don' do meth. So, will never be the ignition advanced pleasure that JB4 is. Cobb? Yeah. See for yourself.

Procede had excellent results neck'n'neck w/JB4 yet for reasons unknown threw the BMW market away. Evidently they didn't like competing with Terry's pricing.

Pays yer moneys & takes yer chances. JB4 has a sterling reputation, doing much much more than Dinan or Cobb.

Now then, Mr. Vendor, you have to ask yourself one question: Why G5?

Detailed investigation will reveal interesting capability.

Curious about one item - what does Cobb do with CAN bus comm?

i dont tune or anything so apologies if this is a stupid question, but am i reading the graph right by assuming that you lose tons of low end torque and power as opposed to stock?

Whoa! Mighta been way behind the times couple o'posts back - corporate no longer promotes Dinan?

I steadfastly maintain that Nitrous Oxide is much more fun than Nitrogen, and I refuse to fill my baloons with anything else.

If you are talking about my log there is no horsepower torque or figures shown on it. These are engine parameters taken as the car was running WOT in 3rd with a shift to 4th at 6250rpm during some testing. The green line sloping upward left to right across the page is the RPM track.

The torque & horsepower curves based on dyno runs are pretty much the exact same shape as stock just with higher numbers, in my case 415ftlbs & 375whp. The tune is delivering more power then stock from 1000rpm up.

Yup. Get to know your ride a little better too - there's an install. But busy hands are happy hands, and you'll acquire expertise - always a good trade t'this ol' boy.

Mind you, suspension issues will be more pronounced. Do one, you'll want the other, for some pretty good reasons - you can bring your N54 up to M performance. Past if you like.

BMW that stated effective 9/1/08 BMW would not offer CPO certification on any vehicle with non BMW performance modifications. This issue has to do with vehicles not passing EPA emission checks and owners expecting BMW warranty to fix the problems.

If the time comes I still have my 3er and I need a CPO job I'll let you know if dinan plays well with an already coped car

Dinan has its own CPO program, not sure how it works but you might lose the BMW one but pickup Dinan's

I have no idea lol I just know if my transmission dies in march and they say it would have been CPO covered and now it isn't even after I got it installed at the dealer I'll call up my SA at another dealer and have her put me in another car and never work with dinan/that dealer again (OOOOR if BMW really does me dirty I'll hop to an AMG,IS-F, or RS/S ) problem solved and I'm not out 5 figures

But if they're cool I'd continue to use dinan parts/ service at a premium cost.

The price is based on level of coverage and the mileage on the car. There are multiple options available. 4 different levels of coverage with add on options for electronics and 9 different month/mileage options. For example the "Ultimate" (essentially full "bumper to bumper" coverage) 48mo/100K (from the date you obtain the coverage), $100 deductible, on a car with over 35K miles is $5004. The bottom tier coverage of the same 48/100 and $500 deductible is $3346. The prices are non-negotiable.

4 yrs, 100K @ between $3.35 to $5K(bumper to bumper), interesting. Anyone put paper to pencil on this one to see if it's worth the insurance? At least you will be getting, presumably, better parts. I'm usually not one for extended warranty plans but these 335i's are not cheap to fix and do have their problems, more than most!

I started out with JB4 because of the cheaper price. However, I moved on to Cobb for its user friendly interface. It is painless to install or uninstall. One does not have to go under the hood every time a dealer visit is around the corner due to warranty work.

Also, I like the features of access-port with all its lighted up display ability as a electronic gauge. I like the torque output reading these days that I have set on my display. It is always fun to switch between different parameters etc.

Anyways, so far I have been very happy with my Cobb tune.

You don't need the BT cable to clear the codes for cobb do you?
