RennTech HHT (hand held tuner) allows you the unlimited ability to switch between tuned and stock ECU programming and requires no ECU removal. RennTech proprietary tuning module stores both the RennTech tuned file and your vehicles stock file. The module plugs directly into the OBD2 port and delivers the file you choose directly to the ECU. Programming takes only a few minutes and the vehicle can be reflashed at any time as many times as you wish.
RennTech proprietary ECU upgrade for the Mercedes M278 Biturbo engine offers huge gains in performance across the entire RPM range without sacrificing around town comfort or daily driver reliability. With the newest update of their Software Upgrade for the M278 4.7L V8 BiTurbo, RennTech boosts the 550-Series to AMG Power Levels. The RennTech upgraded M278 now produces 540 HP and 705 LB-FT at crank.
Compared to power numbers by Mercedes-Benz, the E 550 gains up to 105 HP and 262 LB-FT. This Software update delivers up to 10 HP and 99 LB-FT more than the previous version. The vast amount of increased torque across the entire RPM range gives the 550 an extra edge to compete with AMG powered vehicles. All this without sacrificing around town comfort and daily driver reliability.
