Hi Folks,

Anyone with the experience of having an ECU remap done by DMS of UK?

I have a 525i and am thinking of using them. Any experience or comment would be most welcomed.

I have also heard conflicting comments if remapping would damage/cause more wear and tear on the engine. Any thoughts?

Thanks in advance

DMS have a very good name. Not the cheapest, but amongst the best.
Getting a group buy together (same day & location) is one way to get the cost down.

Hp/torque gains aren't as good as forced induction cars, but you might find you get a bit more go out of a 525, plus any flat-spots can get ironed out.
Not the greatest bang/? return though.

Oh, and on extra wear - theoretically yes, but nothing extra you'd really notice. Its not as though you drive it @100% all the time.
More chance of increased wear with turbo(s) or s/c though.

Many thanks for the feedback junno!

You'll only see about 10-12bhp extra - perhaps noticable but not a huge difference. Some of the 'character' of the original will be lost for the better - e.g. certain flat-spots for emission reasons.

No real issues on wear and tear but you should tell your insurer...

DMS are highly recommended but I've only see people raging about turbo-diesel remaps as this is where the main business is!
