Toyota remapping

What a Toyota remap actually does

A remap rewrites the software in your car's engine ECU. On a modern turbocharged Toyota that is worth around +24% on power and more again on torque, and on the strongest Toyota engines we hold it is as much as +83 bhp. The peak figure is the part people quote, but it is not the part you feel. What you notice on the road is torque arriving earlier, a sharper response to the throttle and a much wider band of usable power, so the car pulls where you actually drive it instead of only at the top.

We hold data for 109 Toyota engines across 21 models, 83 diesel and 19 petrol, each with its standard and Stage 1 figures. Put your registration in and we will show you yours rather than a range.

Every file is written for the specific engine and proven on our own Mustang AWD rolling road here in Maidstone. We keep your original file, so the car can be put back to standard at any point.

Stage 1

Software only

No hardware changes. The car keeps its standard turbo, exhaust, intercooler and catalyst, and stays road legal and MOT-ready. This is what most Toyota owners have, and it is where the value is.

Stage 2

Software plus hardware

A file written around parts you have fitted, usually a downpipe with a sports cat, an intercooler or an intake. The hardware on its own does very little; the gain comes from mapping around it.

Stage 3

The build

Turbo, injectors, fuelling and often internals, calibrated from scratch on the dyno. A project rather than an appointment, and we will tell you honestly whether your engine is a sensible base for one.

How we do it

Reading and writing a Toyota ECU

The right tool for the unit

We run Alientech, Magic Motorsport, Flashtec and bFlash. Between them they cover the Bosch and Continental ECUs used across the Toyota range, old and current. Which tool a car needs is decided by its ECU, not its badge.

OBD or bench

Most cars are read and written through the diagnostic port with nothing removed. Some locked or later units have to come out and go on the bench. We do bench work here rather than posting your ECU away, so it is the same visit.

Proven, not assumed

Our research and development bay holds a Mustang AWD linked dyno rated to 2000bhp. Book runs with your remap and you leave with a printed before-and-after graph for your own car.

Questions

Toyota tuning, asked and answered

How much power will a Toyota remap add?

It depends entirely on the engine, which is why we publish the figures per engine rather than a headline number. Across the 109 engines we hold, Stage 1 is typically worth around +24% on power, and as much as +83 bhp on the strongest. A modern turbo engine gains far more than a naturally aspirated one. Put your registration in and you will get the figures for your exact car.

Is remapping a Toyota safe for the engine?

It is when the limits are respected. We work inside the tolerances the engine was designed with, check the car over before we write anything and road test it afterwards. What damages engines is chasing a number past what the hardware can take, or a generic file written for a different specification of the same car.

Will a remap affect my Toyota warranty?

A main dealer can detect a remap and may decline an engine or drivetrain claim because of it. We keep your original file and can return the car to standard before a dealer visit, and we offer an optional engine warranty on Stage 1.

How long does it take and can it be undone?

Most cars are done in about two hours through the diagnostic port, or the same day if the ECU has to come out for a bench read. It is fully reversible: we hold your original file and can write it back.

Will it use more fuel?

Usually less on a steady motorway run, because the engine is working less hard to hold the same speed. Driven harder, it will use more. The gain in economy is real but it is not the reason to do it.

Do I need to book, and where are you?

We are in Maidstone, Kent, and we also run a mobile tuning service. Send us the registration and which stage you are interested in and we will come back with what your car needs, what it will make and a fixed price, usually the same working day.
