Advice req - Differences between similar diesel cars & chipping

[Eddles]

Insurance increase for the box is £150 per year, plus nearly £400 for the box itself. I don't think I'd save enough fuel to justify this, unfortunately

Having worked in the calibration business for Ford doing emissions and performance work on diesel engines on their small vehicle lineup (Fiesta, Focus and Mondeo) for production models I can say that the maps the cars come out of the factory with are EASILY modifiwed for better econony (but worse emissions). Seeing as the MOT test only measures smoke then this is ok. I think that an Eco map would give approx 10% better economy.

I have a calibration tool for Fords and am going through this process for my Focus. The injection timing maps can be massively advanced within the emissions area to give better fuel economy. At some points it is running -2 degrees timing, and best economy would be 10 degrees.... a massive 12 degrees difference that would give a great economy boost

Box is "removable" of course - not that I condone not telling your insurance...

Insurance is a pain. The previous owner of my car had 17in wheels fitted but despite the fact I bought the car from a Skoda dealer as "standard" my insurance is about 30% over just because of them.
