If you plan to make changes to the engine software via HP Tuners, you will need to unlock your PCM if the vehicle is after 2014. Keep in mind that this is separate from the OBD Port Unlock for 2018+ cars.

Negative. The engine lifespan remains unaffected by the disabling or enabling of the MDS.

When we optimize the spark table, we usually do it for LPG. In some cases, when you change the angle of firing the fuel mixture, you get better performance from the engine.

By default, the throttle body waits the engine to get to higher RPMS to fully open when you push the pedal all the way down. We change the setting, so when you push the pedal, the throttle body opens immediately.

By default, the Stellantis vehicles operate at 550-650 rpms. This is the main reason they eat the camshafts.

When the pump runs at 550-650 rpms, the oil pressure can be insufficient unless you use a high volume/pressure aftermarket oil pump.

Adjusting the idle rpms to 800 enhances oil pump rotation speed for increased pressure.

NOTE: Applicable only to V8 models.

At present, 51R Tuning Solutions does not engage in car parts installation or car maintenance and repairs.

The engine and transmission software (Operating system) cannot be modified using normal diagnostic tools and software like JScan or AlfaOBD

On the vehicles after 2018, the Factory OBD Port is locked. We offer bypass cable or bypass module for some models. This can be used with Jscan/AlfaOBD

At the current moment, no one has succeeded to unlock these vehicles and there is no ETA when it will be done.
