ECU Tune Stage 1

MWM hand-held module for Mercedes GLC 300 x253

about the function

Today’s engines are controlled electronically using software. ECU Tune accesses this software via specially modules in order to bring maximum performance when you want it and retain the comfort of a daily driver when you don’t need it.

The MWMods ECU Tune is a user-friendly device, it stores both MWMods Stage1 file and your vehicles STOCK firmware file and allows an unlimited ability to switch between firmwares . The module plugs directly into the OBD2 port and delivers the Stage1 file to the ECU, programming usually takes 1-3 minutes. The power increase is achieved by adjusting such parameters of the engine control unit as air/fuel ratio, ignition timing , throttle mapping and boost pressure for turbo-charged vehicles.
MWMods ECU software is developed on the dyno and verified with multiple runs and logs.

ECU upgrade for the Mercedes M264 engine offers huge gains in performance across the entire RPM range without sacrificing around town comfort or daily driver reliability.

Stage1 Most Wanted Mods:
– Software changes only , no physical interventions.
– The priority is the resource.
– Maintenance of the stock version = maintenance of the tuned version.

frequent questions and answers:

Do I get a warranty on a hand-held tuner ?

MWMods warrants to the consumer that all of our hardware will be free from defects in material and workmanship for a period of a year from date of the original purchase. Before sending a hand-held tuner , we check VIN of a vehicle in order to exclude the possibility of a mistake. If the module works first time , it will work all the time. However, if suddenly stops working, we ask for a video and a photo to make sure that there are no external damage.

Will i get pops and crackles?

No , MWMods hand-held tuner won’t add neither pops nor crackles because it doesn’t disable any engine protection systems.  

Do I have to keep the module plugged in after tuning?

There is no need to keep the module plugged in all the time. You can remove the module after ECU upgrade
