Not sure which MaxxECU is right for your build? Start with our most popular ECUs, chosen by customers for everything from fast road and track cars to serious race and competition vehicles.
Start with the build, then choose the ECU.
Every project has different ECU requirements. A classic naturally aspirated conversion doesn’t need the same hardware as a turbo road car or full race build. Start with your project type and we’ll point you in the right direction.
Classic EFI conversions
Modernise fuelling and ignition with a standalone ECU, crank trigger, key sensors and tidy wiring. Street or Sport suits many classics; Race is there when you need more protection and I/O.
Enquire NowFast road & turbo builds
For boosted and fast-road cars, focus on boost control, wideband feedback, logging and engine protection. Choose enough spare I/O for future sensors and upgrades.
Get ECU adviceTrack, race & drag cars
For hard-use cars, prioritise logging, CAN integration, launch/traction options, gearbox strategies and safety inputs. GEN2 Race and Pro suit the most complex builds.

Start an enquiryMaxxECU buying questions
Which MaxxECU should I buy?
The right ECU depends on cylinder count, injector and ignition outputs, trigger inputs, CAN requirements, gearbox control, logging needs and future plans. Send us the build details if you want a recommendation.
Can ASD Tuning supply and install MaxxECU?
Yes. We can supply MaxxECU products and support installation, wiring, setup, calibration, datalog review and aftercare.
Can I buy parts only?
Yes. You can buy MaxxECU products directly from the shop. If you need advice before ordering, contact us with the vehicle details and goals.
Is your stock information up-to-date?
Yes, it is as up to date as possible. Sometimes things slip through, but we try to stay on-top of it with accurate lead times should we not have an item in stock. We do our best so that you know when you order something, you’ll get it next working day!
What's the difference between the ECU kits?
With the universal standalone ECU kits, you’ll find they come in different options. The main option we recommend is auto-selected, however you can usually adjust the kit to include a different lambda sensor, or move down to a standard kit, connector kit or a unit only. You can find a kit comparison on the relevant product page.
Do you really stock that many connectors?
Yes, we stock a huge number of connectors to try and make it easy for you to build your own MaxxECU Kit in one place! Why shop around when you can find everything in one place. If there is anything that we don’t have, contact us at info@asdtuning.co.uk so we can make sure we get it in the future, or order it in for you!
What happens when you don't have stock?
Well, if an item isn’t in stock, we will contact HQ and order it in as soon as possible! If anything differs, we will contact you right away with options on how to proceed!
Not sure what to order?
Send us the vehicle, engine, wiring, fuel system, power target and intended use. We’ll help you choose the right MaxxECU and supporting parts before you buy.
