ESS now offers a DIY option for S85 tuning.

Easily store and switch between up to 10 tunes.

Instant access to stock and tuned files.

Updates and support via internet / email.

Software support for all US and Euro spec vehicles.





MSRP $1,295 + shipping

M5board introduction pricing $1,150 + free shipping

To order visit www.esstuning.com and use coupon code "Directflash" to apply the savings.


S85 dyno tested "stock"




Software Features :

-8400RPM limit, higher available as custom order
-Removed top speed governor
-Reprogrammed torque management
-Reprogrammed throttle response
-Reprogrammed ignition, vanos and fuel parameters for optimum operation

The software is compatible with performance cat-back exhaust systems. Header software available upon request.


Typical performance increase is 10-15WHP and 10-15ft/lbs of torque on 91AKI with software alone. 93AKI version will under normal conditions develop 15-20WHP and 15-20ft/lbs of torque.

Can BMW tell that you had an aftermarket ECU upgrade (ESS) if you flash the ECU back to BMW OEM before bringing it into a dealer for service?

No

Direct flash software is different than our standard software in terms of coding. To change over it would require a complete reflash of your currect software and cost would be the same.

Contact Eloy at RPI to check on this.

I read here on another post here that the dealership scanned a "tuned" car and while it did not detect a "tune" per se, it did collect data that the car exceeded 8,250 RPM and thus voided the warranty. I believe the car needed engine repair.

Any comments regarding that? That is what worries me about flashing the ECU.

If RPM limit is a concern you can always request stock RPM limit with our software.

[email protected] I think this ESS Tuning Direct Flash software a great offer but I have a question for you, according to the E60 M5 Complete vehicle Aftersales Training (see link bellow) the DME for the S85B50 (control unit Siemens MS_S65) can only be reprogrammed up to 63 times. Do you confirm that ?
