Hi I\'ve seen that people do this electronic port activation thingy. I\'ve got an S4 n/a engine with no acv or pump.
Does anyone have a how to guide on how put a gauge in, so i can tell when the aux ports are open or even opening still. i think they are as i get a whoosh and im off. But at the mo i\'ve gotta drive to work and fuel ain\'t gettin cheaper! so would be nice to know the best cruising speed.

Do i have to have a s5 vdi??

any info would be gratefull i had a look on rx7club but not sure!!
Cheers Greg

I have one of these guages, I\'ll try and have a look monday, busy untill then.

One way of telling if the ports are open is the slight change in exhuast note

Cheers,
It doesn\'t have a distinct note change its just always loud, the pedal goes down a little quicker at certain revs, like it\'s allowing more flow through the system! but it would be nice know visually when they are open and closed so i know when i\'m savin the pennies! or not savin\' them as it were!

oh, they open at 4.5 revs. Its not sudden, which is why you don\'t notice. Similar to vtec without the kick:D
