Superchips - can they help economy in petrols?

[The Hitman]

Hi, I've been wondering if I could get my Hot Hatch to be a little more frugal, obviously changing the way I drive is the first step, but I might be getting a job that will put me into heavy traffic and a lot longer journeys going to and from work, which means certainly a lot more money spent on the flammable stuff.

I don't want to get rid of the car but I know it might hurt my seriously pocket. A friend of mine told me that if I had a Superchip installed I could get a remote in which I could switch between economy running and sport...is that true or is it as I suspect that they just change the ECU to pump out more power regardless of economy?

Thanks

They do the bluefin (blufin?) unit that can hold several different maps, that you can switch between as and when you desire. Usually they hold a standard map, a map for 98RON fuel, and a map for 98RON + performance air filter.

I've not heard of superchips doing a specific 'economy' map. Even if they did, you'd probably only see an extra 1-2mpg. You'd be better off (money wise) not forking out for the chip in the first place.

Given how much a remap costs, plus the added insurance, it'll take a while to get it back in fuel costs.

No worries, sounded a little suspect at the time but wanted to run it past you guys first.

When I chipped my XC90 I kept a recod of mpg out of pure curiosity.
THere was definitely a very slight improvement but no more than about 1 mpg

Spending a pound to save a penny. The question should never have been asked.
