CLS 550 RENNtech ECU Upgrade M278
RENNtech is proud to announce our latest ECU performance upgrade for the all new M278 engine currently in the C218 CLS 550, E550, CL550, S550 and other upcoming Mercedes models.
We have been hard at work refining our performance tune for these engines and are pleased to announce our latest ECU upgrade. It’s clear that the 4.6L V8 biturbo engine from Mercedes is certainly underrated from the factory and though our extensive testing and R&D; our ECU upgrade truly unleashes the performance lurking in the M278 engine.
RENNtech’s ECU upgrade for the M278 offers huge gains across the entire RPM range; increasing crank performance numbers an additional 70 HP and 80 TQ. This translates to an astonishing 530 HP and 606 lb/ft of torque at the crank! These numbers are factored at a conservative 15% drive train loss.
The performance increase is instantly noticeable at the bottom end and continues throughout the biturbo engines broad powerband.
Here is the CLS 550 (C218) dyno sheet:
Our CLS 550 stage 1 ECU upgrade is available now for $2,740. For additional information, visit out product webpage:
