The metering unit can go out of sync very easy. Sometimes a drive around the block is enough to knock it out. Sometimes a year later there ok. It really is down to luck of the draw how good your metering unit is.

Obviously it can be many other small things if it's not setup correctly to start with.

If you tuned 10cars chances are 4 of then would have metering unit issues of some sort.

Jano has nobody found a way to refurb these units to a good standard?

You can buy them new at around Ł1600 if your crazy. Lol.

but people claim to be able to do it. I'd like to try before I buy tho..

It takes a lot of calibration inside which i don't think many companies would get involved in trying to get right for such a limited market. However there are many engines which require them to be working where no other option is available. So there must be someone who can it will prob be down to value for money, when you could just buy another one in the hope it works better.

I had to change mine in the past as it just wouldn't hold tune like Janos says the next one was fine just luck of the draw
