March 19, 201213 yr i bought the car z32 tt 2 weeks ago and it has a boost switch fitted and the switch just stopped working it still boosts normally but when u flick the switch it doesnt make any difference what could it be
March 19, 201213 yr Author iv taken the switch out and followed the cables and that and it all looks ok there isnt any markings on any of it so i think it was a cheap bog job
March 19, 201213 yr Where do the wires go? Could be many things, but does it go to the ECU? Could switch between two different maps...
March 19, 201213 yr Author Yeah it goes to the ecu and connects to a light blue wire how would I find out if there is 2 different maps
March 21, 201213 yr Author I didn't get a chance 2 do photos yesterday but I went to a hap car meet and randomly it started working again up to 19psi so I'm really confused could it just b a sensor somewhere playing up?
March 21, 201213 yr 19psi? What turbos are you running? You could be dropping in and out of safety boost (7 psi) if it isn't running right, didn't know you had a problem, just a mystery switch, tell us what's been going on... Edited March 21, 201213 yr by Tudor...
March 21, 201213 yr Author The car runs at 7psi and flick the switch and it jumps to 14psi but then the switch stopped working but last night it started working again at 19 psi and I couldn't say what turbos its got the previous owner said it was running at 380bhp but I don't have any proof this is my first 300xx and I don't know a lot about them what else do u want to know and I will try and find out
