A well-respected name in the tuning game, ESS Tuning has announced their S63TÜ ESS T-700 Performance ECU Software for S63TÜ M5/M6.
ESS has built some of the fastest BMWs in the industry and continues to carry the tradition with the introduction of their performance software for S63tu powerplant. As Southern California's premier ESS dealer, we were among the first to receive the Stage 1+ software to put to the test on our in-house dynojet to verify results on a completely stock 2013 BMW M5 test subject.
Needless to say, we were very impressed by the results.
ESS T-700 Flash features
- Stage 1 or Stage 1+ configurations
- Bench Flash for FULL ECU control, unlike piggyback controllers
- Optimized Throttle response in Normal, Sport and Sport Plus modes
- Reprogrammed Torque management
- Full OBD2 port access to retain diagnostics/datalogging/critical safety systems
- Top speed/VMAX removal
- 91/93 octane maps
- Removed cat check option for those running Catless downpipes (off-road use only)
Details
Vehicle: 2013 BMW M5
Transmission: DCT
Modifications: Stock (baseline)
Octane: 91 (baseline)
The charcoal filters were quickly tossed and a set of BMC Filters were added once the ECUs were flashed and run back on the dyno to gauge results with a bit of 93 octane added. With a
95whp gain and
109ft-lb. in Torque, the tune did not disappoint! The ESS T-700 Flash offers
full control over the factory ECUs without relying on cheap piggyback controllers to manipulate data to trick/fool the DME while keeping full compatibility.
Flashing will be performed at EAS's headquarters in Anaheim, CA shortly. Also, greater results can be expected with a set of catless downpipes and higher octane. Stage 2 software is close to completion and will soon be offered as a package with larger turbos to those with the need for even more power.
Expect to see some quick M5s coming out of our doors soon.
Stay tuned.
