Plugs into the OBD port. Your original file is kept, so you can put the car back to standard at home.
Watch live engine data in the app, before and after a new file is written, and reset fault codes where the car supports it.
Powergate 4 is linked to us through Alientech's cloud. You read the car and the original file comes to us. We write your tune for your car and send it straight back to your app.

Search the list for your make, model and engine.
Send your registration and we will confirm your car is supported, then come back with the price of the tool and your file.
I recently got my Ford Ranger booked in with these guys & it was a quick and easy process. Cheaper then the competition & a quicker turn around time too, can’t recommend enough
First class .efficient service . Highly competent crew . Only gripe didn’t get offered a coffee while waiting. Otherwise highly recommend
Car was seen at the appointment time and pre-diagnostic check identified fault with the EGR. Remap was completed but advised to get EGR fixed in order for remap to be completed. Honest service and would recommend.
Alientech's current Powergate: a compact OBD tuning tool you run from an app on your phone. It replaces the earlier Powergate models, so it is the one we supply.
Up to four configurations, so you can switch between, for example, a daily map and a track map.
You plug the tool into your car's OBD port and read the original file. It comes to us, we tune that file for your exact car, and send it back for you to write to the car. You keep the original, so you can put the car back to standard at home, for example before warranty work.
Not quite. A full dyno session lets us measure the car while we tune it. A home tune still gives us full access to properly tune the ECU, so you get more power and better drivability than an off-the-shelf module.
Yes. For example a safe map for daily driving on pump fuel and a stronger one for track days on race fuel, or a map with and without water methanol injection.
Yes. The tools are in stock and sent by mail order worldwide, with remote support from us.
In the UK, normally 1 to 2 working days. We confirm the tool suits your car before we send it, so ask us first rather than ordering blind.
Not once it has been unboxed. That is why we check your car is supported and talk you through it before you buy. If you are unsure, ask us first.
Search the vehicle list on this page, or send us your registration and we will check it for you.
