I'd be happy to learn anything i can. So please feel free
As for the BOV, for you it may seem retarded but i too prefer the louder blow-off sound. I wouldn't go as far as to handicap the car myself in order to run one but i simply bought it like this and it functions fine.
So, I'll share what I've learnt. BOVs that go to air are a bad idea, it will be covered on this forum and about 1000 others. The reason is mathematical, the MAF measures the amount of air that has gone into the system, by using a recirc this air is a known quantity always, if it goes out of the system via the BOV, you end up with the car thinking it has absorbed x amount of air, but this is then vent out, so other sensors which are expecting that volume either throw an error or just throw the amount of fuel in for that expected air that isn't there. The results usually aren't great.
As they have said (in an internet forum kinda way
) is that your best bet if you wish to play with the ecu etc is go to a known configuration and go from there, and using a tool like me7logger is just damn useful.
So my experience so far with me 7.5 (I've covered MS43 before) is that it is an advanced little unit, and I've seen the map that we got from a mapper and there are some issues it, however unless you know exactly what the mapper has done you won't know the reasons they did the bits they did, so starting from scratch is the safe way to do it because you at least know what is being changed.
Spend the cash on an FTDI cable, run a vm on a laptop, and just log, log and things start making more sense.
