Important Points to Consider

The manufacturer of MaxxECU has set a very competitive market price for their products. We resellers have all agreed that no sales below the list price are allowed under any circumstances.

This means that no matter where you buy, you always get the same price. If you see MaxxECU being sold at a discount, let us know!

The reason for this is mainly to ensure high service and the best possible support for the systems. It simply prevents unscrupulous companies from selling the systems cheaply by ignoring support.

Additionally, there is still a component shortage throughout the electronics industry, so a slightly higher price ensures that units are still available, which benefits everyone.

Important disclaimer

All MaxxECU dealers are contractually obligated not to actively market or sell MaxxECU products outside their designated territory, which in our case is Sweden. This is to ensure fair competition and allows local dealers who provide tuning and support to also earn from sales. We therefore ask that you first contact your local dealer.

If you for example want to buy our PnP solutions, please consider buying the ECU from your local tuner and the adapter harness or adapterkit from us. We will still support it fully.

However since EU law strictly prohibit cross-border purchase limitations, you are free to buy from wherever you want within the EU and EES.
If you do insist on buying from us, please only contact us for support and questions. 
We would also like to know why you prefer buying from us, so we can inform MaxxECU.

If you still simply on our own accord want to buy from us due to our outstanding customer service, superior products and/or support, we cant stop you. But also understand that your local MaxxECU dealers might not be so happy about it.

Support and Experience

Whether it's for the street or racing, we believe the most important thing for you as a customer is that what you buy is installed correctly, configured, and mapped correctly, so it can function as it should.

Support is therefore super important. Unfortunately, this is something that other manufacturers and many other tuning firms apparently do not understand.

We therefore strongly recommend that you consider where you buy your engine management system from. Buy where you know you'll get the best service and support. Don't buy from the local dealer just because it's the closest.

At Engdahl Motorsport, we take pride in daily supporting a large number of customers both over the phone, online, and even via Teamviewer where needed.

With over 1000 installations and mappings behind us, we are well acquainted with MaxxECU and consider them to be the hottest and most cost-effective systems on the market. You won't be disappointed, we guarantee it!
