Can/Does the ECU, cut fuel and ignition between four or eight cylinders?

You mean the redundant system? No - not on this engine or ECU.

Are you asking if the Monaro has displacement on demand? If so the answer is no.

DOD requires the engine to have various valves built in to make it run otherwise just cutting fuel to one or more cylinders would make the car run like a bag of bolts.......

I don't thin there's much wrong with 23.5 mpg on a 200-mile motorway run at speeds of 80moh plus. I have a mate with a new Disco diesel and he only manages 24mpg. Work it out and compare the cost taking into consideration the higher cost of DERV against petrol. I know which car I would rather drive!

I've managed 22/24mpg on a run - but I don't do runs, so it's 16mpg all day. I don't have the tune yet though - hope that improves it some.

I only do about 4K a year, so i dont have much to complain about. I was only interested after seeing something on Sky which had DOD.

18mpg is a small sacrifice for the grin I have on my face when I'm driving it

Am getting used to the figures but some tooling round London, up to Brum, three days of short drive to and from work followed by return to London and driving around equals 20.5 mpg. Not too bad but hoping it might improve a smidge with running in...

I haven't been too shy with the throttle - it sounds too good! cloud9

26-30mpg on normal cruise. Recently averaged 31mpg on 4 hour trip (230 miles), including 1 hour in town. Not bad for LS1 with 2.3L twin-screw super. Regularly get 23mpg on mixed and 16-17mpg urban only.

My GTS, which I got on Thursday, has just done a round 200 mway miles at 26mpg with the cruise set to 90. Speedo is not exaggerating the mileage either as I do this trip regularly.

Congratulations on the GTS - I've had mine three months now and still drive everywhere with the window down What colour is it, and what mods (if any) has it got?

Edited to apologise for slight thread hijack, and to add that I don't in fact know what mpg mine gets. As I mostly drive it round Milton Keynes, land of endless roundabouts, it's not great, so I'd rather live in ignorance!

It’s Phantom Black, mate, what’s yours? It’s totally standard at the moment although it may have been remapped as I’ve got a dyno chart that shows it was making 357bhp 4 or 5 months ago.

The noise is just the best thing, I loved my burbled up Impreza(still do) but this really is another level…Got a mate to blip whilst I stood behind and it just sounds evil...and then there’s the power..”think I’ll just overtake….2..no..3…nah…5 cars” almost as much fun as me bike.

Wasn’t expecting it to be as good (relative term) on fuel as the Impreza. I hired a VX Clubsport(255kw) when I was in Aus in 2004 and I only got 21ish out of that, mind that was on the GOR. Sad habit of checking mpg I know but I always like to know how far I can get on a tank.
Ah roundabouts. Over in Swindon, we know all about them……………………..

Husaberk,

Bought my GTS-R this week also from Swindon - I think you may know the people I bought it from (?). Have not had the chance to do many miles yet but I know what you mean about the noise and the grin factor.

Mr Monkey

You're right my Missus works with the wife of the previous owner of your GTS-R. One of my colleagues who works at another Swindon site has a GTS-R as well, haven't found out which team he works in to introduce myself though.

I'm still keep looking at my drive and thinking "Wahoo!" I work in an office of gearheads and I'm ahead on points at the moment.
