Dyno tuning and ECU remapping.
Custom calibrations and multi-map tunes built around how you actually use the vehicle, then built and checked under load on our 4WD roller dyno or 2WD hub dyno.
Built and checked under load.
- A baseline run before anything changes
- Tuning under load
- A final run to confirm the gains, with the curves to take home
Four-wheel drives go on the roller dyno with all four wheels driving, the way they're used on the road. The hub dyno bolts straight to the hubs of two-wheel-drive cars, so there's no tyre slip and the numbers repeat from run to run. You see the before and after on a power sheet instead of taking our word for it.
Not only that every car is road tested to confirm results and drivability
A tune that suits how you drive.
A remap changes how the factory ECU handles fuel, boost and timing. On a towing rig that means more torque where you need it; on a daily driver it's a stronger, smoother pull.
Multi-mapping is an optional extra that lets you switch maps on the move, which suits a vehicle that only tows some of the time.
We remap automatic transmissions as well, so the gearbox shifts to suit the extra torque. We do it on Toyotas and on other makes.
Tell us what you drive, what you tow and where you go, and we'll recommend the tune that suits. For LandCruisers, Hiluxes and Prados, the Just Autos packages pair the remap with the parts to support it. Find your vehicle.
Remap or Chip
A tuning box or piggyback sits between the factory ECU and the engine and adjusts the signals going between them. A remap changes the calibration inside the ECU itself, so fuel, boost and timing are adjusted together.
Both have their place. A remap suits most factory engines, and a piggyback chip like the Unichip Uni-X suits older models like the 1HDFTE. We'll recommend the right one for your vehicle. More on that is on the engine management page.
Before you book.
Tell us about anything that's been changed on the vehicle, and any warning lights or faults. A tune works best on a healthy engine, so if something needs fixing first, we'll tell you before we start.
Plan on the vehicle being with us for about a day. If it's still under new-car warranty, keep in mind that a remap will affect it, so have a chat with us before you book. And if you ever want to go back, every tune can be returned to standard.
After the tune.
Once it's done, you can leave it be. A tune generally only needs revisiting if you change something major on the engine later, like the turbo or injectors.
If you're planning more work down the track, tell us now and we'll set the tune up with that in mind.
Dyno tuning and ECU remapping questions.
Why tune on a dyno?
The tune is built and checked under load on our 4WD roller dyno or 2WD hub dyno, so you get a before and after power sheet instead of taking our word for it.
Do you tune vehicles other than Toyotas?
Yes. We tune most common-rail diesels, including the V6 Amarok, and petrols like the Y62 Patrol. With the 2WD hub dyno we've also had a Kia Stinger and a McLaren GT4 in. Send us the make, model and what's already been done, and we'll tell you what's possible.
What's the difference between a remap and a tuning box?
A tuning box or piggyback sits between the ECU and the engine and adjusts the signals. A remap changes the calibration inside the ECU itself, so fuel, boost and timing are adjusted together. We'll recommend the right one for your vehicle.
Will a remap affect my warranty?
Yes, a remap will affect your new-car warranty. If your vehicle is still covered, have a chat with us before booking it in.
How long does a dyno tune take?
Plan on the vehicle being with us for about a day.
Can a tune be put back to standard?
Yes. Every tune can be returned to standard if you ever need it to be.
Will my tune need redoing later?
Generally not. It's usually only needed if you change something major on the engine later, like the turbo or injectors.
How do I get a price?
Send us a quote request with your vehicle, rego and what you're after, or call Shane on 0407 287 264. We don't list prices on the website because every vehicle and set-up is different. We'll reply within 1–3 business days.
