I've recently stumbled across ECU remapping on our car, it's a 2015 MKIII Fabia Estate SE, 1.2TSI petrol (it's the first "nice car" I've ever owned after upgrading from a Citroen C1) and I've been wondering what the ins and outs as researching gives conflicting information.

I've read that a remap can not only improve performance, but with it has an improvement on responsiveness and even fuel economy - is this really true? With it, are our options to:
a) Push it and reap some performance benefit on dual-carriageway/motorway driving etc.
b) Drive it as normal now and see some improved fuel economy

If the economy really is a thing, is it something noticeable..? For us, economy plays a big part in the car, one of the reasons we went for the Fabia Estate was the economy wasn't much less than our dinky C1 for about twice the space and general "class" the car has.

How is reliability impacted too? I obviously get that if components are being worked harder they're going to wear quicker, but how bad is it, really, especially if we're driving it "as normal" most of the time. This car has very quickly become my pride and joy and I plan to care for it as best I possibly can, but I've also just as quickly got that interest in making it "mine" (even though it's a family car...)

The first site I found for a remap is advertising a ~46% gain in BHP, and ~8% increased fuel economy with it:

You will get a notable more shove.

I'd go for a good company, not one from a random exhaust shop etc.

Revo, Unicorn, MRC may be able to do it.

Thanks for that link, definitely sent me in the right direction. We've got the 90PS model, so I've found the Package for our engine (https://www.onlyrevo.com/product-details/software/skoda/fabia-mk3-2015-/232/stage-1) and looks like it'll increase power and torque to about the same as the upgrade you linked - so I'm assuming we'd see even more impact from it?

They claim fuel economy is unaffected given driving stays the same, is that likely to be true?

I had an APR mapped Fabia with the same engine but the 110 model. It was much quicker than standard but I didn’t see an increase in economy. Maybe down to my driving style but I’d say it was doing 3-4mpg less over a tank.

Don't remap for fuel economy....

However every car i have owned has been tuned somewhat and I've never noticed a decrease in economy when driven the same. Usually better!

I wouldn't consider the remap for the economy, but one of the things that appealed was the increased power and torque without dragging the MPG down too much. Especially having that extra grunt while not having to push the car so hard.

Any turbo engine is worth mapping. Even some aspirated engines are (alot are detuned).
