135is tune

[Mike135is]

Ok so Cobb isn't making a tune for the 135is .. I'm not sure if I want to do a piggyback tune like jb4 or proceed any suggestions?

Forget about the Cobb, just go Jb4 and call it a day! You will never look back

Any tuner can mess up your engine, as long as everything is dialed in accordingly you can't go wrong. The off the shelf maps for the n55 Terry offers will suit your needs.

Hey man!
Check out "Le Man blue 135is small build" thread.

He got DP, FMIC and JB4(soon).

Tuner for the JB4 over @ http://www.burgertuning.com/products.html

Yea, "some guy" sounds like a reliable source. Especially since even the piggyback tuners need flash tunes (most reliably COBB) to get 100% out of their product. Regardless of what piggyback, without a flash it can get dangerous -- You're basically running double factory boost, on the OEM fueling & ignition curve So now what happens is you have to buy a flash to make adjustments and run two tunes

Buy COBB & let an established tuner to properly modify every channel (Boost, Ignition, Fuel, VANOS, etc), utilizing the OEM logic while maintaing the existing safety parameters.


**Edit -- Just realized you're N55.

The only issue I have with JB4 is that it is a piggyback tune, not a proper back end flash tune. The only ones that are easily available and flash via OBDII are Cobb and Dinan. There are others out there but some require sending in the ECU etc or some other obscure method. The biggest benefit apart from being a full back-end flash from Cobb is that the PTF guys make customs maps with that flash method and they are best-in-business.

Steve from Dinan explains best why black-end flashes are superior to a piggyback in this video.

steve dinans video is marketing bs and full of misinformation. there is no cobb tune for 135is, nor will there be any time in the foreseeable future. dinan products are overpriced and underwhelming. jb4 is easily the best option for this particular application

As a neutral bystander who may be looking for a tune in the near future, explain to me where the Dinan video provides misinformation.

COBB has the 135is listed on the website, so they clearly intend to offer platform support once they crack the DME. Dinan products are questionable (overpriced yes, but the FMIC and some other stuff are very quality pieces), but the arguement he's making (Piggyback vs. Flash DME tuning) is 100% spot on.

NO piggyback, whether it's on the N54, N55, S63 Tu, etc, or sold by BMS, Vishnu, Switzer, etc, it CANNOT adjust Fueling, Ignition and Cam Timing. All they do is add a bunch of boost, while running off the Factory Fueling & Ignition Tables.

Heaps of misinformation

firstly, while his motorsports div is still cranking out reasonable stuff... His street division has been trash (and massively overpriced) for the entire time E8x/E9x has been out.. to the point of the 1M intake being twice the price (more) of the standard N54 intake when it's 100% identical... He's in no position to throw stones.

The fact he uses the word 'lieing' in the video instead of something a bit more neutral is sneaky.. And the fact is, the DME is capable of self adjusting an INCREDIBLE amount from factory.

The fact that dinan has less control over an N54 than cobb does.

The fact that there's 20,000+ JB4's out in the wild with very few issues directly caused by the JB4 itself.

Stability control has never been affected by the piggy's, and only DCT clamp pressure is an issue due to load tables not being correctly reported.

and the final point being .. dinan can do things others can not... like suck and still make bank i guess?

Bottom line is, Dinan hasn't been close to holding any platform records in the past two generations.

actually, the piggy's can adjust fuelling via various methods (and is how they get it to work on the N55), and TECHNICALLY do timing via CPS.. and to be fair, they actually control boost better than the DME can... on top of that, they are superior meth controllers.

I mean.. without the piggy's the N55 wouldn't have anything other than stock tune... That would suck.

If you wanna ride the DME's safety system, be my guess. Most newer factory DMEs can adjust fueling & ignition timing up to 25%, but it's designed as a safety precaution because of poor fuel quality. The BMW DME has been the saving grace on this platform, because if you tried that on a EVO or STI , kiss your motor good bye. And since when is piggyback boost control any better than flash??

The N54 had the same development: prior to COBB PROtuning being released on the N54, 400 WHP on stock turbos was impossible without meth (used as a fueling bridge). Now, it can be achieved on 93 octane. Now the N55 OEM turbo is a serious power limitation, but I expect the JB4 vs. COBB PROtuning (which N55 got last month) performance differences to become much more noticeable with the Vargas upgrade.


There's a reason that both vendors that started out as strict piggyback advocates are both offering flash tunes (requiring them for higher power setups) to their boost/meth controllers.

[Chunner]

Hypothetically, I'd like to bring my brand new daily driver with a Stage 3 Dinan tune to my BMW SA and say, "hey, something broke"... please go fix it and go about my busy day in their courtesy vehicle. Instead of shitting bricks if they would void my new car warranty. Although, I am not knocking any silly $500 piggyback tune. To each there own… To some enthusiasts out there, peace of mind is everything. Remember, you pay for what you get.

At this moment in time, for a late 2012+ N55, only JB4, Dinan and BMW PPK is available. Cobb is my favorite, but I am in the same boat as all other late 2012-ers being that there is currently no support. I like PPK and Dinan too for the already mentioned reasons. The negative to them of course is that they are expensive and you can't flash custom maps.

Saying Cobb will 'never' provide support for the N55 is a bit of a bold statement. They may have alluded to it in some posts over in the E9x forums, but if someone kept asking you over and over (me included) if you would add support then what sort of response would one expect? Dinan's done it? They have a team of software engineers specifically for fiddling with the software.

Further to that, the M135i, M235i, 335i, 435i, 535i etc. all have the N55 engine. That's a hell of alot of cars = big user base = big R&D:Potential sales ratio for any tuner should devote time to cracking the security.

The F-chassis DME's are EVEN MORE secure than the E8/9x DME's.
