Smarty

Do you drive a Ram or Dodge with a Cummins diesel and want more from the engine? Smarty makes programmers that plug into the truck’s diagnostic port and give access to new settings for the engine and transmission. Here you’ll find Smarty programmers and accessories for diesel trucks, where you choose the level that suits your driving.

Programmers built for the Cummins diesel

Smarty is developed by MADS Electronics and has long been a well known name among owners of Dodge and Ram pickups with the Cummins diesel engine. The brand has focused narrowly on these trucks, which means the software is tailored to the character of the engine and transmission. The idea is simple: you should be able to update the truck’s software at home without special tools and return to the stock settings whenever you need to.

Smarty’s key products

The core of the range is handheld programmers that connect to the OBD port. With them you can choose between different power levels, recalibrate the speedometer for larger tires and wheels and change a number of settings such as idle and shift behaviour, depending on model and year. Many programmers can also read and clear fault codes, so you can quickly see what a warning light means. See each product for supported engines and model years.

Frequently asked questions

Can I go back to the stock software?

Yes, Smarty programmers save the truck’s original settings so you can load them back again. This is useful if the truck is going in for service or if you sell it.

Can I adjust the speedometer for larger tires?

Yes, most Smarty programmers can recalibrate the speedometer when you fit larger tires or change the gearing. The truck then shows the correct speed and mileage again.
