Real life MPG post remap?

[moob]

I've only had my E320 for just under 2 weeks - I'm finding the fuel economy, or lack thereof, to be a bit of a concern. I seem to be getting around 26 on short trips (around 3-4 miles in traffic) and just over 30 on a country road run. Coming from an Accord diesel that was capable of over 60mpg, this is a substantial adjustment!

I am considering a remap, but only if I'm likely to see some kind of MPG gain.

I've read quite a few discussions on this with varying opinions given, but wanted to hear it from fellow Merc owners. I know a remap can throw out the trip computer read out, so experience and opinion on brim to brim MPG preferred.

Also, could Anthony from GAD recommend someone near Glasgow ?

I am just finding my way around my CLS 350`s consumption.

ALL town work - a properly calculated 23 MPG , I think the "official" figure is 25 ish.

Did a 200 mile round trip on Sunday (Paisley - St Andrews) and averaged 41 MPG , this consisted of 60 - 70 on the motorway followed by 50 ish from the Kincardine Bridge to St Andrews via some small villages and towns.

What impressed me more was the total range showing on the display just after filling the tank and heading onto the motorway , it was reading 760miles @ 60mph. It seems that engine temp is critical to achieving anywhere near the "official" consumption.

Cheers Kenny, I'm struggling coming to terms with this juice guzzler!

What is your overall average , my 320 over the last 5000 mls is 34 mpg with 2-3 ml message runs showing 27 mpg and a 30-40 ml run showing 37-39 mpg
I did remap a 2.5 vw touareg once and it did show a very good increase in mpg but mostly needed more power as 2.5 was low on power for the heavy vw.

remember that you have come from a 2.2 honda (2 cylinders less and MUCH lighter than an E class) so it will be more economical. you now have a car weighing approx 1.6 tonnes (from memory of my 210) or more, with a 3 litre V6 or a 3.2 straight 6 engine.

I had a 210 E300 turbodiesel and even sitting at 70mph for decent distances, i couldnt crack 40mpg. 39.6mpg brim to brim was the BEST it could achieve, and around town i think id struggle to get it above 20mpg.

on the average A road, sitting at legal speeds, i could get 30ish (approx) from it but it was by no means, in the scheme of things, an economical car. the cdi should, however be noticeably better on fuel than the old turbodiesel i had. there are members here who, on motorway runs, have returned 45-47mpg from similar cars, at legal speeds.

Good evening,

We can help indeed but we have no dealers in that area as of yet. We can offer the WT4 system which is VIN locked to your vehicle and can hold your stock file and upto 9 other maps! If you could pop an e-mail to Anthony@gadtuning.co.uk I can send you all of the technical specs and price.

Many thanks

I think its around 30mpg, but I haven't driven it any real distance except back from Perth to Glasgow where I'm sure I saw about 38mpg driving like an old fart.

Its a 56 plate 2006 so its a V6 .

I was (almost) prepared for a significant drop in MPG, just now quite as scary!

I've yet to see how it does over a tank, so will probably get a better idea then doing a manual calculation.

Anthony, thanks, but I really haven't a scooby what you've just said mate.

Scratch that Anthony, I've just seen the video after a wee Google. Interesting, but how do I input that software?

Just to add to the discussion. I'm getting an average of 24mpg, all heavy traffic, town traffic. Thats with a lighter C350CDI. On the mway, at a decent pace, its returning 35mpg (standard map). Post remap the mway fuel economy seems to have improved about 10%, thats brim-to-brim figures. I was getting similar with a 530D.

Im so sorry I have only just seen your comment! The WT4 system will pull a READ from your vehicle very much like KessV2, CMD, Byteshooter ect... (All map communication tools)

Then you plug the unit into a computer or laptop and install the software and email us the file. We then tune to your spec and code the file to your unit and email it back. You then have the power to WRITE your new file or STOCK file whenever you want.

Many thanks
