Get the 90 mapped and you're laughing

I've got the 90 and a few people have been talking about getting it mapped, sorry if I sound really silly but what does it actually do if I get it mapped?

Simply ?

Modern car and van engines have an electronic management system that controls fuelling. This is ran by the brain of the engine, the ECU (Engine Control Unit). When you put your foot down, the ECU decides how much fuel and air to mix, squirt into the cylinder and ignite. Diesel and petrol engines work a bit differently, but that isn't really important for the purposes of this explanation. The ECU also controls the boost of the turbo (if you have one).

If you have your engine remapped / chipped / chip tuned or whatever other term you want to use then the ECU parameters can be changed, to give more performance and in certain cases more economy, getting more from your engine.

This is done in several different ways, the most common is to connect to the vehicle diagnostic port and reflash the software on the ECU, with a standard map for the vehicle in question. This does need specialist equipment, it's not a DIY job, but as it is all done with software, then a new map can be uploaded to your vehicle ECU pretty quickly and can often be completed in less than an hour.

If you're thinking of having this done speak to forum member and fellow DS3 owner Jamie Shires at SP Tuning - he's done lots on here and I wouldn't recommend anyone else
