Frequently asked questions about tuning Renault Sport in Sydney.


Will my ECU be locked if I get a tune?

Not at Race Spec Tuning, we do not lock your ECU. Our files are encrypted to protect them and can easily be overwritten if required with the original file from your car.

What’s the problem with a locked ECU ?

Firstly, in most cases your ECU is then locked to the device which was used to lock the ECU. The consequence is that in future only that device can be used to access the ECU calibrations leaving you dependent on both the device and its supplier for the remainder of the cars life. This also means that no other tuning can be done by other tuners using their tools, and your Renault Dealer can no longer update your ECU anymore. The end result is you will need to purchase a new ECU, which by the way will no longer have a tune on it. Please contact us for details on how we can help you get a custom local tune for your RS.

What happens when I book a tune?

When you visit Race Spec HQ for your booking we’ll check some basics are o.k. with your RS and take a read of the ECU to make sure we can connect. Then we’ll perform a power run on the dyno and check everything is o.k. to load the tune, we’ll then load your tune, perform some after runs, and make minor adjustments to the map if required. You’ll also get a printout with your results (.jpg emailed as well) to show your friends 🙂 For Custom tunes, we’ll do the same, but you’ll need to leave your baby with us so we can have some dyno time to run logging and fine tune your map to make sure we can safely extract the maximum power and customise to your requirements.

What payment methods do you accept?

We accept Cash, Paypal, Visa, Mastercard and Amex. (Tap, Swipe or Insert)

Do you provide local service?

Yes we are locals, based in Emu Plains Sydney. But that doesn’t mean we can’t come to you, make us an interesting proposition and we might visit your city.

Do you have a Guarantee?

We sure do; we’re so confident you’ll love our tune we’ll give you your money back and restore your original tune for free within 30 days if you don’t.

What happens if my Dealer overwrites the tune?

Don’t stress, just because your car is tuned it doen’t mean the dealer can’t update it, if its Race Spec Tuned anyway. If your dealer happens to wipe your tune just let us know and we can restore your tune for you. Look on the bright side, at least you’ll have an excuse to visit Race Spec Tuning HQ.

Do you only tune Renaults?

Yes, we only tune Renault, sorry.

Can I get a Race Spec Tune if I already have a tune?

That largely depends on what/who/how your car was previously tuned. There are a range of reasons to bring your already tuned RS to Race Spec Tuning. You may just want to improve performance by having a tune customised on the dyno to suit exactly your car Perhaps you’ve added some more upgrades and want a retune to take advantage of extra power available Maybe there are problems with the current tune e.g. Coolant temp safety maps removed, Error codes, etc If you’re not sure if you need a retune why not just book a power run on the dyno and compare your results to see if there’s more in the car with a better tune. Good news is in most cases we can retune any Renault Sport, but there are some proviso Get in touch to discuss your options
