Eurodyne now offers stage 1 software for the 2017-18 Audi RS3 and TTRS.
The reflash does not require ecu removal, and with the optional Powertap flash tool can be performed by anyone with a windows laptop and internet connection.
Power and torque gains are as follows;
91 octane: 67 bhp and 79 ft/lbs of torque.
93 octane: 85 bhp and 92 ft/lbs of torque.
Our dyno results with stock software were 393 whp (~435 crankshaft hp). This agreed with the power reported by the ecu while data logging with stock software. (516 nm tq @ 6000 rpm logged from ecu. 516nm = 380 ft/lbs. 380ft/lbs X 6000 RPM \ 5252 = 435 hp).
With our stage 1 software, we measured 465 whp (~521 crankshaft hp). This agreed with the power reported by the ecu while data logging with our stage 1 software. (600 nm tq @ 6200 rpm logged from ecu. 600nm = 442 ft/lbs. 442ft/lbs X 6200 RPM \ 5252 = 521 hp).
The included flash software will allow you to do datalogging, and supports some diagnostic functions such as clearing fault codes.
We have also added the ability to scan and recode some other modules in the vehicle.

This same car recently ran back to back 11.1 second quarter mile passes at almost 124 mph with no modifications besides the reflash.
