▀▄ eas | ESS S63TÜ M5/M6 Piggyback Backend ECU Software released
Backend ECU software from ESS has been released for the 2012+ S63TÜ M5/M6 for use with aftermarket piggyback controllers that control boost, etc. This targets a number of areas not accessible to piggyback type controllers for maximum performance gains.
The ESS Backend Software File offers the following options: - Correct AFR control for higher boost pressure. AFR target is set to 12:1 under high load/boost conditions. - Top Speed Governor (VMAX) removal - Increased RPM limiter (+400 RPM) - Removal of catalytic converter diagnostic functionality (for off road use only) - Removal of Cat Heat Cycle/Cold Start (for off road use only) - Updates can be performed via OBD2 Flashing is performed in-house at our facility in Anaheim, CA or ESS's facility in AZ. Note: This software does not offer any performance gains without a piggyback controller installed. The piggyback ECU software intended to be used as an elevated backend platform, specifically designed for piggyback type tuning devices.

What's the benefit of going this route over a tune? I may have misunderstood but it seems like you need the DMEs to unlock them. Is that correct?
Just curious. I would think if I have to ship my DMEs I might as well go with a tune. Most go with piggy as its removable and doesn't required unlocking the DMEs and voiding powertrain warranty. Thoughts?

In the N54/N55 community, having a JB4 + Backend Flash gives them maximum control over the parameters and allows them to fine tune everything along with having all the capabilities of the JB4. |

At this time, the DMEs must be bench flashed once in order to remain unlocked. We always prefer the flash route, but this provides an elevated platform to piggybacks to work from, as well as the other options that were not available previously. BMW can detect piggyback use even if its removed before service. This usually doesn't become an issue unless a failed part is being claimed under warranty and PUMA case is opened. Some prefer piggyback tuning, some prefer full flash. Choice is up to the end user. RPM limit is raised, not removed.

It sounds like what a few other members on here have already been doing for a little while! especially the ones that have been consistently setting new records, flash + jb4 + this + that. Hire someone from government to break the code so we can just get the obd2 flash without sending in dme.

What's the point of raising it, power dying off after 5500 rpm

So to take advantage of this new back end software you have to send in your DME to bench flash? Or is the new software to be updated on the actual piggyback module?

We would need the DMEs here for flashing. If not local, they can be overnighted and returned the very next day.

All fine tuning (and methanol control) is still handed by your piggyback settings, this is an elevated platform to work from which will offer a bit more to work from.

Currently the N54/N55 guys have unlocked OBDII flashing for their DMEs so there's a ton of backend flash maps for various fueling setups, meth setups, etc. So one can choose a flash based on their setup and load it in and it'll help their JB4 make even more power or even modify the flash to suit their specific needs. Eventually that'll be where my fellow M5/M6 owners would want to be to help fully unlock the full power potential of these S63TU beasts. Backend flashes also have the added benefit of deleting the cats for catless DPs, etc and are typically nowhere near as expensive as a full tune. |

I like the idea of removing the speed limiter though I have never hit it - it is the principal of the thing. |

We cannot discuss pricing in this thread, but pricing can be found on our website and vendor's section of the forum. I'll send a PM as well.
