REMAP - acceleration is coarse and consumption has rocketed

[DrunkenNinja]

I recently had a service that cost me about €820 (inc. a 300 Euro Remap) inc. VAT

Anyway I got the car back and in heavy traffic when tweaking the accelerator there is a slight vibration feedback, it's nothing huge but you know what it's like when you know how your car should feel.

Is this vibration normal given the extra torque/economy provided?
Another thing is it's guzzling Diesel, before I was getting 10Km/Ltr and now it only does 9.3/Ltr, I was told that the remap would make it more economical.

The car does fly now though, even though there is still the turbo lag which I thought would go. (no I am not driving it like a racing driver)

Just out of interest does this service seem reasonable? Not including VAT

Oil €50
Oil Filter €10
A/C Filter €28
Air Filter €35
Filter Diesel €35
Radiator liquid €12
Brake Disc €58
Wipers €32
Labor €150
Tuning €300

I do trust my indy mechanic but this time seems a little too steep, on top of that he told me my exhaust manifold is on the way out and will need changing next time I visit and said it would cost me €600 he said he could tell cause when starting the engine he could hear a noise that disappeared after the first minute or so.

Recently I have started to hear a clunking sound coming from the back, initially I thought the seats were not seated well as they might have been moved during the service or that something was rattling around in the back but I can't find anything and it's driving me nuts.

Thanks for helping the new guy.

Cheaper than the UK for service parts and labour. We pay between £50 and £150 per hour for labour +VAT. A decent remap would likely cost more too. Of course you can get cheaper ones, but they may not deliver what was expected.

Clunking noises most likely suspension components like bushes, but your indy should have found them. And am assuming nothing loose underneath or in the trunk.

Sounds like your remap is a 'power' type which is less economical until you learn to use less pedal.

If you are using your new found performance then of course it will use more fuel - how else do you think it does it ?

The savings in economy come when you learn to use the torque more and thus put the car under less pressure to obtain the same forward movement as before

Just a thought about the economy: are you sure you're reading the numbers right. Economy is usually quoted in the UK as miles per gallon and the metric equivalent is consumption, measured in litres per 100km. If your consumption has gone from 10 to 9.3 then the economy has improved not deteriorated.
I don't think the car will display the units you mention in your post - I know mine won't.
Just my 2p worth,

It means yours do not have the NAV OBC, the consumption part looks like this:



For the first couple of weeks I agreed and thought the lower the figure the better, but when was messing with the settings one day for consumption it clearly states km/Ltr, thats when I realised I was mistaken as 10km per Ltr is better than 9.3 per Ltr.

I am driving the X the same as before so managing the torque is not the problem here, I can't thrash the car in day to day traffic, this is just worse consumption but added power, maybe the consumption advantage will only kick in when hitting the motorway?

Well, OK - I used to have an E53 with Nav but that was about 18 months ago and in all honesty I can't remember all the units it displayed - no doubt a current E53 owner could. The units you mention aren't available on my E70 with Nav, but given that it's a Canadian model perhaps its just that BMW don't offer those units here.
Your screen shows figues of 18 and 17.9: did you change the units to mpg when you took the picture?

You have the choice of Km per Litre, or Litres per 100 Km.

So in the first case, the higher the better, in the second case, the lower the better.

Go in the setup menu and see which option has been selected.

That's not my photo, it's just something I googled to show you that the option does exist.

It's km per Litre, and shows 9.3 now which is lower than the 10 reading shown before the REMAP so the economy is worse now.

one is stored in consump (1) and the other on consump (2) so it clearly shows the difference.

Get your tuner to check what he has set the torque limits in gears are as it may be set too high in the lower gears which can cause the prop and centre bearing to vibrate
