50 or 60 WHP for $1K or 100 WHP plus other nice features for $500............I think I'd go for the JB4. Do you get charged $100 each time you have to send the BMW code in to be 'massaged'? That could get expensive if there were a few DME updates from the factory. Mick Last edited by bmwmick; 07-12-2011 at 07:49 PM.. |

Ultimately it was the ease of use with the ESS unit that sold me. They have a very good reputation too. |

One is designed to "trick" the ECU and the other remaps the original factory ECU software. Remapping the original factory software takes more knowledge, is more sophisticated and has a higher degree of difficulty then adding a plug in harness to the signal. We feel it is best that the vehicles built in adaptation and safety control systems always know what is going on, especially when turning up boost. This allows the ECU to make corrections on the fly when needed depending on conditions and allows for issue free ownership. You can also do more to change the way a vehicle performs and drives when you have 100% control over the entire operating system. |

This is what I was telling people even before the ESS tune was announced for the N54-a flash tuning solution 'at-home' where you could download maps would take the market by storm if it performed as well or better than the piggybacks like the JB4 etc

Thanks for the good information guys. May have made up my mind as well as far as which direction I go when I finally get my Z4.
Quick question, I can find 92 octane pretty easily here, but 93 is hard to come by. Would I be able to run Stage 2 with 92 octane or would I need to stick with stage 1? |

So what is the expected longevity of the turbos with this remap? Won't the turbos die much quicker due to the increased boost?

Hey Roman, why kind of numbers are you getting with 91 octane on stage 2? I thought that stage 2 had a minimum of 93 octane?
DirectFlash Stage 2 : Top Speed Governor: Removed RPM Limit: 7200RPM Fuel requirement: 93US/98Euro Horsepower: 400 DIN (Stock 306) - 390DIN if used with stock intercooler Torque: 550NM (Stock 400NM)

Wow, nice! I may have to order one of these soon, I'm still waiting for my car to come in. Eagerly anticipating the dyno info on the 91 octane...

Awesome. I was under the impression that I needed 93 octane to run stage 2 as well. Glad to hear it works with 91!

Interesting thread about the ESS Tune software. Living in Sweden and hopefully soon upgraded my Z4 3.0Si to a sDrive 35i I wonder what the ESS stage 2 will perform when running the 35i on 95 or 98 which is standard in Sweden, any one knows??

Also, how is fuel efficiency affected by the remaps? What is MPG for the respective maps? This is also information I hoped would be published. Last edited by dtn; 08-01-2011 at 10:48 AM.. |
