Anyone considered getting their car's ECU re-mapped by places such as 'super chips' to give better performance/fuel economy etc? Are the benefits really as good as the companies would have us believe?
For my 2.4 Audi I can expect a boost of 12bhp for approx £300 - quite keen but any feedback from people who have had this done would be much appreciated. Any info regarding possibility of higher insurance premiums also of interest.
Thanks.

Try AMD for Audi tuning. They actually re-map your car rather than using a generic map.

AMD fiddle transmision losses so there mods appear to make more difference than they do. I personaly do not see the point in chipping a standard normally aspirated car. Better to spend the money keeping the car running perfectly as standard.

I think the theory is that your car is designed for a particular output and if you up it too much then you can expect premature failure of something or other.

I am always on site at Herts Police H.Q. in particular the vehicle workshop and one of the mechanics reckons the 320 cdi mercs they run are remapped and kick out about 260 bhp.
Do you reckon this is true or a load of old pony. If it is true would you advise having it carried out.

That sounds like a lot of dosh for only 12bhp increase. I suspect you wouldn't even notice the bhp difference, but the chip will probably iron out any flat spots in the acceleration.

carayzee, do you have a web link for AMD?

You'll only ever get a power gain with aftermarket chips if you've got a turbo engine, and thats only because it can increase the amount of air entering the engine (ie. more boost) as well as the amount of fuel. 'Superchips' are lies, all they do is dump more fuel in - great. Unless you seriously modify a natural aspirated engine to breath more air, more fuel will do nothing other than coke up the sparkplugs faster! As for 12bhp extra from an Audi 2.4 - who do you think know more about calibrating engines: Audi with their illustrious motorsport history, or some bloke in a shed with his laptop?
Its not even really worth while on a turbo car unless you ensure you have suffiecient cooling, strong enough internal components etc. for the increase in power your after. Unless you don't mind a rebuild every 3,000 miles....

IIRC Superchips guarantee the engine for 3 years after the chip is fitted (providing certain pre-conditon checks of the engine are met I think).
But, no, I wouldn't bother chipping a N/A engine, but would consider doing so to a modern TD unit (which, slightly confusingly, can produce more power but use less fuel, as the thermal efficiency goes up at increased boost pressures!!)

Many thanks for all this guys. Don't think I'll bother with the chip. It is a lot of cash for a small increase in output, obviously the difference (if any) would be marginal regarding performance.
Cheers for your thoughts.

You'll probably find that your insurance company would probably increase your premium by the same amount....
