The chip is not going to damage the ECU unless you fit it wrongly as its nothing more than a bog standard 3 quid memory device plus on the petrol engines the EPROM is already socketed.

The concern would be what the map does to the engine.

Earlier diesels are socketed as well

Been reading this with intrest, the only reason I got involved with megy's 2.5TD is because I used to drive (and still have) a BMW 325 TDSE, (same in line 6 pot engine) to say these Engines are different is a real big understatement, the 325 really does fly, and I mean fly, it goes like rocking horse sh-t, and still returns 37 - 50 Mpg.

I'm still not convinced that the Megy version of this engine is correct, either Vx or BM have seriousley detuned the power to suit the auto box. The missing 30 BHP or so from the Megy version,.... well I cant get my head round it?, the difference between these engines, even allowing for the Power to Wieght ratio is one big wide gap.

My BM 325 is currently SORN at the moment, but Im tempted to sort that and offer a drive to existing OOF member owner's of a Megy 2.5TD  to try for themselves... I think your chin's gonna hit the floor!

It is heavily detuned.  I'm running a chip that is pretty much back to BMW spec (140ish bhp), its definately no match for MV6

I guess in a 1.7t Omega, it will be noticably slower than in a lighter (presumably older if SORN'd) series 3...
