It will only be more economical is you drive it as such. Use the right foot to explore the performance benefits and it will use more.

Do you have access to VAGCOM to see error codes?

Potentially could be MAF problem.

A remap won't make the car more economical generally, it will make it more powerful / allow for more fuelling etc.

I bet if you don't rev the nutz off it fuel economy won't be much worse than standard.

Well most of my driving is round town stuff and i'm lucky if i can get 200 miles to

Yep mine had this problem 19mpg round town 30mpg motorway .Now with a new Maf fitted 38mpg on the motorway 22mpg town i hate town driving so always floor it were possible to catch adrian up but never caught him:D but maybe a trip to jabba with £4000 in me pocket might help;) .

opppss

I watched a MAF on a Golf 1.8T being checked at Jabba recently using VAG-COM and monitoring the readings in Module 01 - Engine - Block 02 - Air mass injection. The readings at idle and circa 2500 rpm were higher than they should be. The diagnosis that the MAF was faulty was confirmed by fitting a new one. SEATCupra.net may have info on what readings one should expect for the various 1.8T engines. Remaps will obviously affect the standard readings.

hi Adrian the only place i can take my car is the local skoda dealer. i spoke to the guy who done the map and he said it could be the air meter sensor. the car surges quite a bit too. do i let the skoda dealer know i've had the car modified or do i just porky pie him and say that the economy has deterioated?

yes, keeping the revs down, cruising steadily at less than ~3200rpm, fuel economy is as good or better than as standard. Flooring it sees 5mpg on the fuel consumption display:eek:

dont worry mate if you want the power you got to pay the price

the same thing happened to mine its doing about 19mpg at the moment seems like im always in the petrol station filling up but its worth it

Same with me 19mpg around town, 25mpg on motorway if booting it and 30mpg if driving sensibly. Oh and 4mpg with foot to floor.

If you were able to get your car to the place which did the remap then, I would recommend that.

If you can't then you're only left with goign to your Skoda dealer. You will have to tell them about the map though but remember, if you have warranty left it will be void.

Mine is running approx 280bhp in low boost mode and I regularly get 350miles from a tank.....as I don't drive the car that regularly now this includes is booting it when ever possible. Must try running it in high boost mode for a week to see what I get out of a tank.

i'm waiting on a throttle body to be delivered to the dealers so it can be swapped on my vRS, i have seen reduced MPG and poor idling and surging also.

generally though i'm getting near enough 300miles from a full tank, mine isnt remapped though.

Had my vRS Octavia for around 2 months now. The computer was showing 29.1 mpg over the last 2K miles when I got it. Since then I get 30 mpg commuting (only 10 miles / day) but had an indicated 41.9 mpg on a 275 mile round trip last week, giving just under 400 miles till empty. Reading these posts concerning remaps I don't think I'll bother.

A work colleague has recently had a 225 BHP Seat Leon and the only average low 20's.

This is very much at odds with my fathers old car. He had an E36 BMW M3 (321 BHP) 0-60mph around 5 seconds but average fuel consumption of 27 mpg.

On a long run using cruise my remapped (231 bhp) vRS will still approach the 40 mpg mark - and I don't drive slowly :D

On the other hand, on a previous (216 bhp) remap, it averaged 8.4 mpg on a trackday at Knockhill :eek: :eek: :eek: :eek:
