A chip or a generic remap, why do either when for the same sort of money you
have a proper custom map done on a Dyno ?
I have done all 3 over the years, the chip or an add on are a at best a serious compromise.
The last diesel I had was the smart car, an add on controller just caused black smoke along with a little more go.
The fuel consumption stayed the same unless you drove it hard, then it was terrible.
Next I had a so called remap, cost me around £225 quid, this was better, more power more torque and better fuel economy.
Then winter came on, the fuel consumption around town dropped to about 45mpg, from a summer high of 60mpg for the same journeys.
So I bit the bullet and had a proper job done, the before dyno run revealed the so called remap had boosted power from a factory 44hp
to 53hp, which apparently is about normal, I just had a better power curve. After the re-map and after half a dozen dyno runs I had a test
run on the road, the difference was staggering, but plenty of black smoke. Bach for a another fiddle and few more dyno runs.
I ended up with 70.88 hp and plenty more torque, fuel consumption improved considerable, the big difference from summer to winter
all but disappeared, best motorway run at a steady 75 gave well over 80mpg, around town average was 65mpg with an easy 70mpg for mixed
driving. I would never again settle for a chip, tunning box or generic remap, custom all the way for me, mind you it was the most expensive option
at £250 all in, the only thing more expensive was the tune it box that was rubbish.
After custom remap.
Before remap.
