Rolling road tuning: Standalone ECU & Renault RS mapping

Megane 250 / 265 / 275 RS 630cc injector re-map


Our custom dyno tuning option for the Megane 250 / 265 / 275 RS. For wilder configurations including hybrid turbo’s with 630cc injectors and more.

Before purchasing you are encouraged to first make contact to check that we have dates available that suit you.


Custom dyno tuning for the Megane 250 / 265 / 275 Trophy. Cup-s model with Euro6 ECU tuning also available on request.

This option is aimed at those with more heavily modified engine configurations including hybrid turbo swaps, uprated actuators and / or larger fuel injectors.

With this option we’ll aim to provide the best, custom tune we can to work with your individual list of modifications. For example, it might be a stock engine with 630cc injectors, exhaust system, induction kit, intercooler upgrade and hybrid turbo, or it might be a forged engine with a larger turbo. If you’re familiar with our existing work you’ll know that we’re no strangers to high power F4R engines!

* If you are planning a wilder engine, 360hp+ for example, it would be best to speak to us before deciding upon engine management solutions – it might be that an aftermarket, standalone ECU is the better choice, or it might be that we need to book you in for the more advanced option.

Our tuning work is custom, meaning every car spends time on our rolling road while we adjust your ECU’s map until the result is both safe and optimal.

Aside from the performance increase the remap will include some additional benefits including:

– Fault code removal for such things as a decat pipe
– Re-calibration for larger injectors, if necessary, with corrected trip computer data.

Q: How is this re-map performed ?
You’ll need to book a slot with us so we can arrange to get your car on to our rolling road. Along with weekday slots we’ll often have weekend slots available too – please just ask.

Q: What parameters are you able to adjust ?
Just about everything. When re-mapping your ECU to accommodate hybrid turbo’s, uprated actuators, intake modifications and so on we’ll regularly need to alter several aspects of the ECU’s behavior including boost control, lambda control, fueling and ignition timing among others.

Q: How long does it take ?
On average it’ll take 2-3 hrs on the rolling road.

Q: What are the common modifications you’ll tune for with this custom tune ?
We’re happy to incorporate induction modifications, intercooler upgrade, exhaust upgrades (with or without a catalytic converter), hybrid turbos, larger injectors, tubular manifolds, forged engines and more.

Q: Will the ECU loose it’s tune or alter over time ?
No, do not worry.

Q: What if my ECU has been locked by a 3rd party ? Can you still work with it ?
Yes, although this takes an additional amount of work and can be subject to an additional £50 fee.

Q: If I’ve had my ECU tuned by you before and I make alterations or upgrades, what will the cost of map adjustment be ?
We thought about this for some time before arriving at what we thought was the fairest solution. Updates and alterations made to any map we have performed previously for you is charged at £80 + the normal dyno hourly rate. This means that simple alterations do not cost as much as substantial ones. An upgrade from Stage 1 to Stage 2 for example might only take an hour hence a cost of £180. Upgrading a map to work with larger injectors and/or a hybrid turbo may take an hour longer.

Optional launch control inclusion.
