I'm aware that the Apexi Power FC has a tendancy to switch the Purge Valve on at idle, so that you end up with what sounds like a mouse tap dancing in step with the usual injector noise.

I have so far only experienced this on an MY98 ECU, and subsequently found that to work around this you can set the idle fuelling above the closed loop threshold, to kick the purge valve back of again.

Is this a 'feature' of all apexi ECU i.e does it effect MY92-96 and MY99/00 aswell ?

Gonna be getting myself an apexi in a few weeks for my MY00, so would like to know more !!!!!
