Mercedes from A to Z: three new protocols unlocked at Shiftech

Engine: Bosch MG1CP003

This is the most exclusive ECU in this series. The MG1CP003 powers the 4.0L twin-turbo V8 in the most extreme Mercedes-AMG models, and is now available from Shiftech.

This ECU covers everything from the classic V8 (55 AMG, 63 AMG, 63 AMG Pro) as well as the E-Performance hybrid powertrains delivering over 800 chevaux in the 63 AMG S models. And it’s not limited to pure AMG models: the Mercedes S 580 and the Maybach SL 680 are also among the models covered.

Calculator: Bosch MG1CP004

Gone are the V8s in these segments; Mercedes-AMG has switched to a 2.0T with an electric turbocharger, paired with a mild-hybrid system (43 AMG) or a plug-in hybrid system delivering over 680 chevaux (63 AMG S E-Performance). This engine is derived directly from Formula 1 and required a completely new approach to make it accessible.

With the MG1CP004, Shiftech is making these engines accessible for the first time.

On-board computers: Bosch MG1CP777 & MG1CS701

The Mercedes compact range has transitioned to mild hybrid (MHEV) and plug-in hybrid (PHEV) architectures. This electrification has required two new control units: the MG1CP777 for the 2.0T and the MG1CS701 for the 1.3T, both featuring factory-fitted protection systems that are among the most complex on the market.

Both are now available from Shiftech.

At Shiftech, this lock is now removed via a two-step process:

1. Remote unlocking (Unlock, from €450): your ECU is sent to us to remove the manufacturer’s software protection. This step is carried out only once per ECU.

2. Bench reprogramming at Shiftech: once unlocked, our technicians work directly on the map on a dynamometer. The original map is backed up before any modifications are made. You can revert to the original settings at any time within 5 years of your visit to Shiftech.
