Is it as simple as just plugging in and downloading the software @
Fletcher
I think so mate. I have a MBP but used a old windows laptop to upload/ change maps with the RS-Tuner.
This might help..
Upgrades Saturday 17th July 2010
After changing the exhaust system and cat, the time had come to remap the car to get the best out of the modifications. I could have gone to a specialist for an off-the-shelf Fastchip map, or do it myself using their own RS Tuner interface and software. Fastchip is run by a Renaultsport mapping expert in Holland. The DIY route is slightly more expensive, but the interface and software allow error codes to be read and all sorts of live data displays from the engine sensors. Better value for money I reckon'.
The interface and cables
The process was very straight forward. I even managed to get the Windows software to run on my Macbook using Fusion emulation software. When it comes to 'on-the-driveway-mapping' an Apple laptop is a must! The first stage was to backup the original software onto the laptop. Then Fastchip give you the very latest Renault software for the car. This upload takes about 30 minutes so a fully charged battery is required. Next the engine map part of the software needs to over written with Fastchip's own 98ron performance programme. This is much quicker and only takes 5 minutes.

The result is far better drivability with more torque available lower down and a higher rev limit - from 7200 to 7500. Added to this is a much improved cold start with no hesitation and 'kangarooing' - a feature of the engine according to Renault!
The normal 5k kick (a characteristic of the 172 engine), where the engine suddenly overcomes a slight torque and power drop before this point, has now gone. This kick isn't VTEC as some like to call it. The very basic variable timing function on this engine is for emissions and smooth idle and operates at under 2k rpm. To some the car feels less dramatic without this kick - but drivability is so much better and you don't need to wait for 5k for things to happen As a consequence, I don't seem to rev beyond 6500 anymore.
Fuel consumption is the same as before. So the only downside is slightly more expensive fuel. Although, the knock sensors are still functioning so if I need to fill up with normal unleaded, the car will adapt £190
