The RENNtech HHT ECU Upgrade is designed for the CL 600 C215 model, specifically for the M137 5.8L V12 engine. This proprietary ECU tune provides substantial performance enhancements across the entire RPM range, aiming to improve power without compromising daily drivability or reliability. According to RENNtech's dyno results, this ECU upgrade pushes the M137 engine's performance from its stock 362 HP and 390 lb-ft of torque to an impressive 417 HP and 446 lb-ft of torque at the crank. The vehicle's stock performance is noted as typically exceeding factory ratings, with the modified performance numbers reflecting the significant gains achieved through this tuning module.
