Tssss Tsss Tsss noise on boost
umm, well il start with issues with check light flashing on full boost, simtek ecu. so started this thread, and put it down to bad fuel
https://www.scoobynet.com/scoobynet-...ntum-fuel.html
so today i filled up and put bottle of nf octane in tank too.
went for blast and in 3rd 6000rpm check light flashed again.
so i then eased off in 4th and flat to floor in 5th no check light on but
then i could hear a rapid tss tss tss tss tss tss noise.
so it seems like a leak or something.
iv changed nothing under bonnet, checked hoses seemed fine.
any ideas where to start.
the tss noise isnt like the dump vale tssss, its a short sharp rapid tsss lol
cars a v4 wrx, fully forged, remapped. etc etc
any ideas people, doing my nut

i think your going mad lol
my car flashes the sel only when it hits the very high revs and only now and again too but i just turn a blind eye to it as i have been told that some can be very sensitive and pick up other sounds that are not det
could your dump valve be sticking or leaking ???

never came with a oem one. well today i reved engine hard and at high revs the dump vale was just dumping air out, still on throttle. so adjust screw in and reved again. didnt loose the pressure. yet to test drive. will be doing it now. misses makes food at bad times haha

I've just had my car in with the same problem. The noise was like the dump valve wanted to dump the pressure but couldn't coz it was getting trapped or bypassed. it turned out to be the solanoid. The pipe had broke off but still looked as though it was connected, it broke off with the connector in the end of the pipe, So it was loosing pressure just as it was ready to dump it hence the funny noise.

well i just drove it and now it doesnt dump when going slow like it used to, but does when booted, also no hiss noise when full boost. to be honest felt quicker, first time in a while it scared me lol best i speak 2 simon. by screwing the screw in iv put more pressure on spring, so need more pressure to open dump valve.
i am going spend few hours when i get more time checking all the pipes as sometimes it bounces on idle and cuts of when first started, so may still av a leak somewhere. just need time.
spend hours under other people cars fixing them mine gets forgotten awwwww haha
