i wish i understood it. i was on their website but i have no idea what im looking at, im to scared to ask as ill get branded a chav in macdonalds carpark. we dont even have a macdonalds where i live
all you need is the standard rs tuner firmware 1.85 or higher mate.
once you have got your hands on one then you then download the software from henks website and that then stays on your laptop ready for each time you want to use the rs tuner.
you then plug the cable that comes with the tuner (usb end) into your laptop and the other end (obd plug) into your obd port that is under your ashtray in the centre counsel.
with the ignition on fully but without the engine running you then click the connect button on the screen of the laptop and the tuner will connect to and read your ecu thus giving you all the info you will need to choose which remap you will need to buy for the ecu set up that you have on your car.
once you have purchased the map you want henk will send it to you via email and you just download it onto your laptop and then follow the instructions to rewrite your ecu with it.
i was sh*tting myself when i did mine incase it all went wrong but it really was easy.
dont be afraid to ask for advice on doing it mate there are plenty of people on here that have got the overrun map(myself included) that dont hang around in macdonalds carparks and this site is supposed to be about people sharing info and helping each other out as fellow clio owners not putting people down and branding them idiots for wanting to try something different!!
at the end of the day if you want to try it go for it as you can change it on and off as many times as you like once you have got the rs tuner!
if you need any help just ask!!
