Check your car
Can we tune your car?
Type your car into the box below and press Check. You get an answer in
seconds: whether we can tune the engine, the gearbox, or both, and roughly how much
power each stage adds. It is free, and you do not need to sign up or give us an email.
Type the make and model. That is all it needs — no year, no engine code.
Golf R · Mustang GT · RAM 2500
Or paste your VIN instead. All 17 characters, for an answer about your exact
car rather than the model in general.
Your VIN is on the windscreen, the driver’s door frame, and your logbook.
Not sure what to type? Try one of these:
We tune European turbo petrol, American V8, diesel and towing,
flex fuel, gearboxes and big turbo builds. If your car does not come up,
start an order anyway — a tuner checks it by hand and tells you
for free, and you pay nothing until your finished tune is delivered.
02The process
How it works
Four steps. Three hours.
There is no appointment, no shipping your ECU, and no waiting for a slot on somebody's dyno. Everything happens through your order page, and you can watch the clock run down while it happens.
01
Read your car and record a drive
Pull the stock calibration out of your ECU with your own interface, then record a datalog — a few minutes of normal driving plus one full-throttle pull is plenty. The stock file tells us which calibration your car is running; the datalog tells us what your particular engine is actually doing with it. Sending both is what separates a tune built for your car from a file with your car's name on it.
Tell us the car, the modifications and which stage you want, then upload both files. Your stock calibration is archived and hash-verified the moment it lands, and that is the instant your clock starts — not when you started filling in the form. From there you can watch it count down on your order page.
Ordering costs nothing. No card, no deposit.
03
It gets built by hand
Your tuner reads your datalog first — knock, fuel trims, actual boost, intake temperatures — then writes the maps around what your engine really did, not what the platform does on average. You can message them directly on your order page while they work, and most people do.
The desk is staffed around the clock, so your file never waits for morning.
04
Download, flash, then fine-tune it free
Your finished calibration lands on your order page inside three hours. Settle the invoice, download it, and flash it yourself with the same tool you used to read the car. Then drive it, log another pull, and send that back — you have three free revisions, and each one comes back inside three hours just like the first.
Your stock backup stays downloadable the whole time. You can always go back.
The desk — six tuners, three shifts, one of them always on
Your file goes to whoever is on when it lands, and stays with
them through every revision. Portraits are illustrated, not photographs.
03Pricing
Stages & pricing
Three stages. One flat price each.
Pick the stage that matches the hardware actually on your car. The price is the complete price for that stage — there is no per-revision charge, no subscription, and no "custom quote" phone call. If you are not sure which one you need, order the one you think fits and your tuner will tell you if you've picked wrong, before you pay a penny.
You pay after we deliver. Ordering is free and takes no card. We build your calibration first, and the invoice only appears once the finished file is sitting on your order page waiting for you. Your stock backup is never locked behind payment — that file is yours from the second you send it, and you can download it back at any time.
Every stage includes three free revisions after delivery, each turned around inside three hours. Gearbox (TCM/TCU) calibration is included in the stage price wherever your platform exposes it, not charged as an extra. Prices are per vehicle, one-off — this is a service, not a subscription, and there is nothing to renew. You keep your files, including the original stock read, permanently. Tunes are supplied for competition, off-road and project use; you are responsible for the legality of running a modified calibration where you drive.
04Your side
What you need
Your tool. Your car. Our calibration.
We do the tuning; you do the reading and the flashing. That means your car never leaves your driveway, you keep full control of what goes into your ECU, and there is no ECU in the post.
01
An interface that can read and write your ECU
An HP Tuners MPVI2, MPVI3 or MPVI4 covers most of what we tune, and the equivalent tool for your platform works just as well — we calibrate the file, whichever licensed tool produced it. You will also need whatever credits or licence that tool requires for your specific vehicle.
02
A laptop and a healthy battery
Reading takes a few minutes; writing takes a few more. Do both with the engine off and a charger on the battery — a flat battery mid-write is the one genuinely expensive mistake in this whole process, and it is entirely avoidable.
03
One honest datalog
A few minutes of ordinary driving and one clean full-throttle pull in third or fourth gear. Log it before you send anything, and log it again after you flash. The second one is what earns you a revision that actually fixes something.
Under three hours. The clock starts the moment your stock file lands with us — not when you fill in the form — and you can watch it count down on your order page. We can promise it because the desk is staffed around the clock — a file that arrives at 4am is picked up as fast as one that arrives at midday.
What do I need to send you?
Two things: your stock calibration, read out of the car with your own interface, and a datalog of a drive. The stock file tells us which calibration your ECU is running; the datalog tells us what your particular engine is doing with it. That is the difference between a tune built for your car and a generic file with your car's name on it. Our step-by-step guide walks you through both reads.
When do I pay?
After we deliver. You order for free, we build your calibration, and you settle up when the finished file is sitting on your order page waiting for you. Nothing leaves your wallet before there is a tune to show for it. Your stock backup is never locked behind payment — it is yours from the moment you send it.
How much does it cost?
Stage 1 is $85, Stage 2 is $120 and Stage 3 is $150. That is the complete price for the stage. No per-revision fee, no subscription, nothing to renew. Three free revisions are included with every order, each turned around inside three hours like the original.
What if the tune isn't right first time?
You send a datalog from the drive and we revise it — three revisions included free, each back inside three hours, same as the first. Remote tuning is a conversation, not a single file. The log you send after the first flash is what turns a good tune into the right one for your specific car, and we would rather you sent it than lived with something that is merely close.
Do I need special equipment?
An interface that can read and write your ECU — an HP Tuners MPVI, or the equivalent for your platform — plus the credits or licence that tool needs for your vehicle. You do the reading and the flashing yourself, on your own car, with your own hardware. We do the calibration. Nothing gets posted anywhere.
Is my stock file safe?
Your original calibration is archived and hash-verified the moment it reaches us, and we never tune the original — always a copy. That backup stays downloadable for as long as your order is open, so you can put the car back to stock whenever you want. We will not start a tune at all until the backup is confirmed intact; that check is built into the system, not a promise.
Can you tune the gearbox too?
Yes, on every platform whose transmission controller can be accessed — shift speed, shift firmness, shift points, and the line pressure that protects the clutches. It is included in the stage price rather than charged as an extra. The checker above tells you whether your car exposes its TCM.
Which cars can you tune?
Most petrol and diesel vehicles with an ECU an aftermarket tool can read. The checker above answers for your specific car in a few seconds, from your VIN or just the model name. If it comes back unsure, order anyway — a tuner confirms it free, and you owe nothing until a tune is delivered.
Are you affiliated with HP Tuners?
No. EcuTunerx is an independent tuning service and is not affiliated with, endorsed by, or sponsored by HP Tuners, LLC. We calibrate files produced by whichever licensed tool you already own.
