Hey everyone,

I was just having a discussion with my cousin on how if my 420SEL got better or equal mileage to my 190E I would just daily drive that, then I remembered about the Megasquirt EFI conversions that are common on m103/m102s...

I was wondering if anyone had any thought/experience with the same on a m116/7? What kind of economy gains would one expect to see?

Also if any one has done it on a m103, what kind of mpg gains did you see? Currently my 190E 3.0 gets about 24mpg at 65-75mph.
