Why map a diesel ?

(1/4) > >>

nath:
What are the advantages of mapping a diesel ( gt tdi 140 ) for example . I don't drive fast and wonder why you would map a diesel ?  I don't do many miles either .  Just wondering really . Would it not make fuel consumption worse ? Would it not make more sense to by a petrol Gti ?  Thanks  :confused:   Is there a Map that would suit my driving without putting extra wear n tear o the car ?

Andy:
Mapping a diesel makes the car drive better and gets rid of that terrible flat spot they have..A good tuner will be able to make a map for your car to suit you..If your not doing a lot of miles ignore all that and get a Gti

Resistance is futile.  BUY A PETROL!!!!

Driving a standard diesel to a mapped one is a huge difference.
As standard TDIs have a very flat delivery, they peak and then sort of fade away very quickly. With a remap you will double your powerband width, from around 1800-2800 in a normal car to about 2000-4200 in a mapped one.
You also gain fuel economy because of the way the boost and fuelling is done, making it more efficient at part throttle openings, meaning you can expect around 6-8mpg increase on a steady cruise.
If you don't drive many miles you should not have really bought a diesel to be honest! That being said driving a GTI even around town the difference is huge, the worst I got from my 1.9 TDI was 450 a tank, the worst I've had from my GTI is 260 (so far...) so really the TDI is more economical.

But hey!  :surprised: :innocent:
