So just how accurate is the MFA? It seems to register your speed/mpg etc even when you're stationary which is annoying.
The reason I ask is that I just fitted an Ecotek valve and am being told I'm getting around 40mpg when on the same journey before I was getting about 35/37mpg (which to be honest seems high in itself).

Ecotek valves are a complete waste of time and money. :rolleyes:

MFA isn't very accurate, it tends to over-read by at least 2-3mpg. Best bet is to work out actually fuel consumption based on miles covered in between fill ups.
As Wayne said an Ecotek valve is a massive waste of money :grin:
-
Yeah there's a pretty big discussion about whether they work but I thought I'd give it a go.

Hmmm, i'm very dubious about them. It will be interesting to see if there is any difference! How much did you pay for it if you don't mind me asking?
-
Mine regularly says 40mpg and i know full well it isn't.

I've just had a look at those ecotek valves. The way they "work" (and I use the term very loosely) is by introducing an air-leak in the inlet, thus making you're car run lean. So you may gain a couple of mpg, but you risk destroying the engine, as people with 8v vauxhals have found out.
