The previous owner had a 2 stage boost kit fitted to the s2 its linked upto a switch but when i flick it nothing seems to happen......how do thy work etc..cheers

 

im not sure , but it could be as simple as switching the amal valve on and off >

someone will flame me down in the biggest possible way if i am wrong though

 

yep just a switch to the amal valve, mine has one on thanks to the previous owner, when i got it it was very hit and miss sometimes it worked sometimes it didnt unless i moved the wire on the A/V just soldered a new connection on and its fine now.

 

anymore ideas on this one peeps

 

if memory serves me correct u can either wire it in at the amal valve or cut into wire 9 on the ecu putting a switch inline i did it once on my old s1 worked well
