Ess vs Cobb tune
I am currently running dinan stage 2 on my 2012 135i and don't like it. It doesn't account for my downpipes and throws the check engine light. I have previously ran an ESS tune on my 08 335i and liked it a lot, but i like the access port and the numbers seem negligible. Any recommendations on one over the other for the n55? Please include the reasoning as well.
Thanks |

In b4 war starts....
Why haven't you considered a JB4? Cobb is kind of becoming obsolete as they have really dialed back their support on the N54/N55 platform. I'm also pretty sure they don't have an Accessport for 2012+ N55s. So that kinda eliminates that option for you.

The Cobb might work in your car depending on the VIN, I have a 2012 and they told me it will work.
Where do you get the ESS info? I have a JB4 and I love it, but I have no comparison : ) |

I checked with cobb and my VIN is applicable. I have 6MT. I have always been opposed to JB4 as many of my trusted friends in the industry advised against it. They indicated it is mearly tricking the ECU versus having a whole new map. Dont know the complete validity of this to be honest. Im open to all opinions and appreciate the responses so far.
Thanks, Brandon |

tvmendoza I am local in AZ and have worked with them in the past through a local shop Goodspeed performance. They have had excellent customer service and i really liked the product, just think that there might be some more power you can squeeze out of the n55 than they are offering and thats why i havent purchased their product yet.

The reason why I asked what transmission you have is because the only time I would hesitate to recommend the JB4 is if you had a DCT car that could not be flashed. The one issue with the JB4 is the piggy back intercepts the signals to the TCU, making the TCU think the power output is lower than it actually is, causing insufficient clamping force to be applied to the DCT clutches. That is taken car of with a BEF. You however have a MT, so this wouldn't be an issue. There are multiple good options for your N55. I have tried PTF flashes, WEDGE flashes, and the JB4. If you are running unleaded/race fuel, PTF is an excellent option. For me, I have tried various flashes, but have only been satisfied with the performance on 91 octane. I still have not received a flash that can consistently run E50, and I have tested a lot (over 20 E50 tunes, and more than 60 logs). In the end, I go back to running the JB4. There is no solution that is as flexible. You can run 91, E50, test your own boost curves, run in kill mode or chill mode, all with a few clicks of the steering wheel. go to the n54 tech forums, there is a boat load of information and actual results from many people from dyno runs, 1/2 mile racing, and even road racing. If you are running unleaded only, I would go with a PTF flash or run a JB4. If you are using ethanol, definitely JB4.

houtan So i contact BMS regarding the JB4 and they indicated i would only be able to run map 1 due to 91 pump gas in AZ... With that being said, i don't think i would even make as much power as i am currently running with the Dinan stage 2. Any thoughts and or recommendations because i don't have an accessport and would prefer not to have to shell out the cash for that on top of the pro tune. By the way, i didn't list the mods i am currently running.. BMS Intake, Berk turbo back exhaust kit, Active Autowerkes front mount intercooler, and evolution race works charge pipe. Thanks for the feedback.

I am on 91 in Maine running Cobb with PTF. They built me a fantastic tune and I am running stock exhaust and DP.

How much boost does Dinan stage 2 run? It is very possible that the JB4 map 1 runs the same or lower boost and you will not see any power gains. But I run map 5 on 91, which is the auto tuning map. Ill take a look at some of my old logs when i get home, but I am pretty sure the boost on map 5 is usually around 16 to 17 psi. So depending on what you are seeing with the Dinan tune, there me be some gains on Map 5 running 91.
My PTF e-tune on 91 hits 20 psi. While the car runs strong, I feel a little uncomfortable running that much boost on 91. They can easily lower it to 18 if I ask them too, but haven't because I am running the JB4 for now to allow me to run E50. There is no argument that our cars can gain much more power on E50, and running the JB4 allows me to do that, and switch back to 91, with basically zero effort.

Awesome, appreciate the feedback. Would i be able to run a PTF tune via the JB4? That sounds like it may be the best option if i was able to load it that method.

Just get the JB4 stage 2, convert it to ISO, run the latest hex file, and don't look back. You will not find a tuning platform that gives you the flexibility the JB4 has. The ISO makes the boost curve smoother and allows you to upgrade turbo's without the need for a reflash. Read up on http://www.n54tech.com/forums/ and make your decisions.
My personal experience with the N55 is the JB4 works better than the flash tuning options available now.

You could go with a ptf BEF, but if you have issues you will get little help trying to figure it out (that's how it's been in the past for me). PTF tunes via flash and may not be able to help diagnose with the JB4 in the scenario. Likewise, BMS may not be able to help if you are not running their BEF or the stock flash because they are not in the business of adjusting flashes from a different company.
You are MT. If I were you, I would start with the jb4. You probably won't even need a BEF so at least initially I wouldn't waste my money on the cobb. All you need is jb4 running ISO, data cable, and if you are planning to run e85 the FLex Fuel connector. see how things are and go from their. You can get the jb4 used on the forums, I got mine for around 375 with usb cable. I would confirm with bms if there are any issues running jb4 with dinan tune, I don't know but I wouldnt think so. +1 apexresistance |
