OM648 220-270hp Tuning Guide

Level: Easy, no mechanical modifications or difficult work

This guide is composed to help you if you have decided to do something as stupid as tuning your OM648 engine 😉 It is based on our experiences and is not an absolute truth. We’ll keep it up to date as we learn more about the engine and if you have any experiences you want to share or think we are wrong about something please comment them below this post.

Generally with this engine up to 270hp the only thing you need is engine tuning. If you want to be on the safe side you can fit our pump coupling kit.

Engine management

We offer different types of solutions for engine management / ECU tuning. The product we sell directly on our page right now and also is remotely programmable is:

The software tuning is easy solution to gain more power. If you have a programmer you can read the stock file from the ecu and send it to us for modification with your specs. Also you can send your ecu directly to us so we can do the tuning with our tools.

Engine

One upgrade that can be worth the money to do is the high pressure pump coupling kit, but it should not be needed below 300hp. Apart from this you shouldn’t need any mechanical changes up to 270hp. Of course your engine needs to be working properly to begin with and if you order the engine tuning please make sure everything is 100% mechanically working before we start the programming.

Drivetrain

Stock 722.6 (W5A580 with om648 and om613) gearbox can easily handle the 270hp power. However if you want to make sure it will last forever (oil change every 60000km) we also recommend you to get our transmission tune. Also it activates true manual mode so the transmission won’t upshift automatically, you get faster shifts, less torque converter slipping and torque limits removed:

Finally

Stock engine breaks and tuning them wont probably make em last longer. Driving style and original condition will also affect how long lived your engine will be. That said this should be on the safest end if you want to tickle your engine just a little bit.
