STEP 1
Pick your car
Make, year, model, engine. That resolves to the exact ECU hardware code your car runs, which is what decides the tune - not the badge on the boot.
How it works
A tune, a price, and three spins of the reels.
Every tune on this site is built and supplied by TuneZilla. What we add is the way you pay for it: take the fixed 10% off, or spin for a bigger one: three spins per order, and the best one counts.
STEP 2
Choose ECU, TCU, or both
The ECU tune makes the power. The TCU tune teaches the gearbox to handle it. They are sold separately and you can take either on its own.
STEP 3
Spin, pay, and check your inbox
Spin three times, keep the best, pay. Tune files are emailed in seconds, and the same links sit on your order page.
The spins, in plain terms
Four reels spell a percentage - two digits, a decimal point, two more. Anything from 0.00% to 99.99%.
If your best spin beats 10%, you get it. If all three come in under 10%, you keep the standard 10% instead. Spinning can only ever improve on the fixed discount.
That is the whole rule. Nothing is staked, nothing is lost, and there is no way to end up paying more than a customer who never played.
Three spins per order, and the highest one counts. Once it is locked it stays with that order for a month.
Two outcomes, worked through
List price of tunes$1,099.00
Your best spin is 42.73%-$469.60
You pay$629.40
List price of tunes$1,099.00
Your best spin is 6.20%, so 10% applies-$109.90
You pay$989.10
How the spins are kept honest
A discount that can be edited is not a discount, it is a hole in the till. Three things keep this one straight.
The number is not decided here
Every spin is issued and held on our server, and the best is applied at checkout. Editing what the page shows changes the picture, not the price.
Three spins, then locked for a month
Once your best spin is locked it stays with you for 30 days. Clearing the page, starting a new order or coming back tomorrow does not hand you another set.
Checked again before payment
The discount is verified against the held record at checkout. If the two disagree the order falls back to the standard 10% and nothing is charged.
In this prototype
the spins are generated in your browser, because the fulfilment server is not wired in yet. The lock, the expiry and the checkout verification all work as described - try editing the stored discount and the checkout will refuse it - but the real protection is the server issuing the number.
Do you need a flasher?
A flasher is the tool that writes the tune to the car. Some platforms are flashed at home over the OBD port; some have to go through an authorised dealer.
If your car needs one and you do not own one, add FlashZilla Pro for $139 at step 3. It ships with your order and stays yours for future tunes.
If you already have a supported tool, skip it. Your files work with it and nothing needs shipping.
