Rolling road tuning: Standalone ECU & Renault RS mapping

Contact us


If you have a query we’re here to help.

If you’re enquiry is calibration related (engine mapping or other ECU work) please note that we do not work with factory engine management systems other than those found in Renault Sport models. We typically don’t re-map diesels or other factory petrol engines. Nearly all of our work is with standalone systems found in competition track, drag, fast road and kit cars.

FAQ’s: (Please read before you get in touch!)

  • As above, we tune standalone engine management on any car and Renault RS factory ECU’s only.
  • Email’s are replied to within 48 working hours with the possibility that some technical ones may take a little longer.
  • Orders placed before 2.30pm Monday to Thursday are dealt with and dispatched the same day, all being well.
  • Sorry, we don’t tune carburettors.

  • Bookings for rolling road time: Please note, following the period of lock-down, we’re experiencing much higher than usual requests for tuning. ** We are taking bookings approximately 6 weeks ahead ** at this moment, so please only enquire about tuning work if you are willing and able to wait. Our sincere apologies for any inconvenience this might cause. Regards, Chris.
