about the function

схема (1)

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 M157 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:

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

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

Prepare the Car: 

The car must be put into programming mode first

Make sure the car is warm and everything is stable

Make sure the car battery is fully charged

Turn off accessories and unplug any SD or USB devices

Don’t change any settings or press any buttons while programming

The car must be in IGNITION position 2 (all cluster leds are ON but the motor is OFF) 

Be Patient in this process, wait a minimum of 60 seconds until the audio head has totally booted up.

Begin Installation:  

– switch IGNITION ON (2 click clockwise) or 2 presses of Start/Stop button and make sure you see all cluster LEDS are ON

– wait till your audio head unit totally booted (60 seconds)

– plug module to the OBD2 (diagnostic socket) under the dash and observe audio screen messages

– select appropriate operation using << and >> audio buttons (or rotate controller knob) (choose Stage1(2) or Factory) 

– confirm with * (star button) or controller knob down

– observe audio screen for messages, you will see the progress bar like [xxxxxx…..% ……….. ] – wait till progress bar goes to 100%

– as soon as you see “swicth IGNITION OFF” – then switch it off and wait for next message

– as soon as you see “swicth IGNITION ON” –  switch ignition ON again

– as soon as you see “remove the module now” – the installation is  finished then unplug the module.

Important: Do not leave the module on the OBD. Use the module only when you want to switch between Stage1 and factory maps.

To switch back to Stock map, repeat all steps of the installation process by selecting Stock map in the module menu.

Some vehicles require a factory map update. To do this, activate Step1: Update before activating Stage1(2). Then repeat the installation process for Stage1(2). The update should run before the first Stage1(2) installation. To return to the factory map, use Stage1(2) again.
