Electronic boost controller

Mornin Matt. While you're there, perhaps you can tell me what method these engines use to meter the inlet airflow / pressure?

Feel free to bung the thread on their site, I dunno how / dont have time (in work again!)

Cheers

Far as I know, it's the MAF sensor on the side of the air filter housing. There's some various literature which might have some useful bits. It's collected from various other sites. Contains quite a bit of info on the electronics side of Toy engines:

I'll pop up a thread on the Oz site for you.

Are you talking about the one in the pipe from the air box? Thats just an air temp sender isn't it? Or is there another one I've missed?

I guess it would measure flow if it was heated as then it could measure 'wind chill' and relate that to flow. It's just two wires though so I dont see how it could do anything other than measure air temp.

Intake manifold. Some info from Vince on the subject.

I've finally reached that point where all the info is beginning to meld into a blur.

Boost spiking isn't THAT common with mechanical controllers. It depends on build quality though, i ran a few on my older car that would spike up to 1 psi (not a huge amount considering it'd straight away drop back down to desired boost) and ended up with a $22 boost controller that i bought from ebay. Total elimination of wastegate creep and 0 spiking, + it held 16 psi all the way to redline with no drop off (once it had spooled up) Do they not sell over the counter EBC's there?

Also a BOV on a diesel doesn't the "inlet" always stay open on diesels, that'd mean the BOV was always bleeding off and you'd lose performance. Or if you mean't on a petrol, a BOV isn't going to help you control boost levels as it's primary function is to stop air flowing back over the compressor wheel (mainly to pass EPA emissions) and it does this by bleeding off air once the throttle is dropped off

Just some stuff to consider
