Hope you are all ok.
You will recall that I promised to let you know how I felt about the remap you kindly carried out
last month. First of all, though, many thanks for your attention on the day. The loan of a car was
particularly helpful as, due to matters outside of your control, the exercise took longer than
When I spoke to Matt the day after the work was done, I was a little surprised that I had not
really noticed any difference in performance or economy. This was probably due to lack of the lack
“wow factor” which others had apparently experienced. I now think that this was due to the fact
that the car already had quite a bit of performance and “wow” so I needed a little time to find the
extra! This was probably increased by the fact that I had only had the car a couple of months and
was still getting used to diesel driving techniques (it is my first diesel car).
You will now be relieved to know that, now I am getting used to the slightly more heavy welly
approach necessary with diesels and the narrower power band, I am very pleased with the extra
performance. As far as economy is concerned, I have found that with gentle driving such as that to
and from Tisbury (due to heavy traffic), I found no difference.
However, on a recent journey from Swindon to Southampton when I used a “press on “ approach and
averaged 60mph from my home to the quayside I got 54 mpg. I think before the remap this would have
been about 49 mpg, so a significant improvement there. I am sort of finding, therefore, that the
faster I drive the better the economy benefits – good job Swindon has done away with its speed
I hope this is some help if another Mazda 3 owner comes along.
