Yeah I agree, there is not a huge amount of difference since the stock IS/1M engine is well tuned from factory. In fact some guys did dyno testing on a 1M and ESS and found only a small difference.
Only way to tell for sure is to do a before/after dyno. |

I ran this software in my personal Z4 35is and I can tell you that you should feel a difference. Do a read on the software currently in your car and send the file to AJ, he can verify if you loaded the correct file. |

I have posted a performance measurement video with data in a new thread of its own, but i thought that this thread was an appropriate place to post it as well.

any onr tried both jb4 and ess stage 2?
earlier some,are un willing to pay for ess tunning cos its locked to the vin of the car ..its fair cos it makes business sense to do so . if you had two cars you would need 2 jb4 piggy backs, so no difference ...only that there may be resale value of the jb4 but i am sure we can also install back the original software when we sell off the car and ask the new owner for a nominal fee to have the ess map roman ESS ... is the 35i map stage 2,similar to the 35is stock map ???are the boost the same ? after tunning to stage 2 will the 35i be on par to the stock 35is ? cant decide but leaning towards ESS as dont want the jerky feeling with jb4 TIA |

I believe both stage 1 for the 35is and stage 2 for the 35i takes the turbo boost target to what is considered the maximum level that the N54 turbos can run "safely". The OEM tune of the 35is obviously run higher boost targets than the 35i all of the time (335hp vs 300hp), and additionally increased targets are available for a short amount of time.
No matter the actual boost targets, with ESS they are available all of the time. I assume the ESS targets arent much higher than the targets for the 35is over-boost, and even if, it will be hard to feel 5-10% extra torque anyhow. But having the over-boost available all of the time makes sense for example in cooler high speed situations, or if you upgrade the intercooler. It seems like a design compromise when the over-boost function is only available for a fixed amount of seconds no matter the cooling available. On top of that there is the added engine responsiveness and, depending on your tastes, drive-ability of the ESS tune. It does not make the N54 or DCT more jerky imo. But of course it makes a bit more sense spending money on tuning a 35i compared to a 35is, given that the 35is is comparable to a 35i ESS stage 1 with stage 2-level performance available as over-boost. I guess the actual psi values are a bit less than what is made possible with the adaptive map from JB. At least I hope so, because I didn't lease mine, and one user here ruined his turbos with JB map 5 (although after tens of thousands of km). . The ESS tune also changes other functions such as ignition timing, vanos position, wastegate control, load limiters, fueling etc but also here details have not been made available so far. Against this I am not sure if the JB can be considered a quality tune, but I like some of the extra functions they added. EDIT it seems ESS stage 2 runs 14-15psi which is similar to JB4 map 5. http://www.e90post.com/forums/showth...=193156&page=4 Last edited by Asbjorn; 03-13-2013 at 08:25 AM.. |

We also recalibrate many other settings in the DME which allow the car to perform like a factory car. This includes throttle response, boost control and having DCT vehicles shift properly as the DME and TCU do communicate. Having the two control systems function properly together is key in getting OEM driveability. If you ever have questions on our software you can always PM or email me direct. |

During normal cruising at say 80kmh I think mine is a bit more quiet with stage 2 (compared to OEM and stage 1). I wonder if it is because the turbos represent a higher resistance to the exhaust flow due to the increased boost?
I also wonder if the baseline boost is changed with the ESS tune? It is really hard to be objective on these sound matters as wind and many other factors play in as well. But in any case, I believe that if you want a significant change in exhaust note, you better look at hardware upgrades instead. |

JB4 Stage2, Map 1 on our 2012 335 xi (E92, AT), AE performance exhaust and BMS intake (no power addition). No DPs, so can't run Map 2. About $500 for the JB4 and $1,800 for the exhaust. The Z4 will walk away from the 335xi. EXCEPT, if it's pouring rain and we are taking off from a stop (just the AWD vs RWD). The Z4 sounds so much better too. But, I have needed to remove the ESS tune a time or too, and each time I had to email ESS for the new software version. Apparently, they change it out or it's set to expire fairly often. But, each time I asked, they were very prompt to email me the new software and answer my questions. I just wish I never had to ask for the new version. At least with JB4, I can walk out to the garage and pull the hardware out in 15 minutes.

I still cant believe that no one has figures to compare yet. I was hoping to see some 0-60 times, 1/4 times of stock, stage 1 and stage 2 differences. Also some dyno comparisions would be nice. Although im 100% satisfied with the ESS in stage 2 I just want to know what the difference is.

I'm sure Roman or someone at ESS has the numbers...I would like to see that as well.

anyone has an experience installing with windows 8 laptop? apparently win8 is not supported by the usb cable driver. There may be a work around. I wanted to check if you guys have any experience. I definitely do not want to mess the update for these technical issues.

Still waiting for the 2FA3 code...which keeps coming up after I clear the codes through the software. Hopefully that will get fixed as well... |
