I have the same prob, think it's to do with the signal from the larger injectors. here's a link to a fix for you.

I've had the same issue with both my m50 and more recent m52 conversions!

I mean I wish my car would do 49+ mpg lol :mad:

Mine's an M52 conversion, my OBC range and mpg doesn't work properly since the conversion.

Interesting, is this just OBC or does it affect the standard economy needle thing in the dash?

Doesn't an M20B25 have larger injectors than an M20B20? Does that mean the OBC or dash economy indicator are injector specific from the factory?
