Mercedes-Benz CLA45 AMG ECU Tune – We were the first!
HG Performance is proud to announce that we are the first in the world to have broken through the numerous security layers of the CLA45 AMG‘s engine computer and have been able to flash the ECU with our own tune. This triumphant breakthrough in the platform is the direct result of HG Performance’ partnering with Jailbreak Tuning, working together to reach a tuning solution that would meet both the demand for improvements in power output as well as the need for consistent drivability and engine response.
The CLA45 AMG was dyno tested on D Sport Magazine’s Dynojet in Fountain Valley and Doug’s Dyno’s Mustang Dyno near Las Vegas while we were out there for SEMA. The numbers quoted in the video above are preliminary, as we have not finalized our tune and final numbers will vary. As of now, we have seen consistent gains of around 70 horsepower at the wheels over stock. We were also able to eliminate early throttle closure which robs power in the last 500RPM of the rev band, now the car pulls hard right up to the limiter at 6,500RPM.
At this time, we are not at a point where we would feel comfortable selling this tune, there is a lot of testing and fine tuning that we want to do in order to ensure optimal driveability and smoothness along with the highest possible level of reliability but we wanted to share our progress with the community. We flashed an early version of the tune onto our car around midnight on Friday after SEMA and drove straight to Las Vegas Motor Speedway to compete in the Optima Ultimate Street Car Invitational on Saturday and Sunday where our lightly-modified CLA45 did extremely well against very serious competition.
Stay tuned for more updates as we have them!
