1.3 kgfm/18psi boost on normal 555 sti ???
 

asked scott taylor the other night as my car had peaked at 1.13 approx 16.5 psi...as i was considering a chip , now today i was having fun and 1.28 registered which is about 18 psi ! i haven't opened the ecu but all looks norma to me ! ( will defo do it tomorrow) . now as far as i am led to believe. 14.7 is what it should be ? no ? any suggestions.... full deacet but getting a decatted downpipe tomorrow . and has apexi jasma decat as is. and std filter:wonder: :wonder: wtf could it be ?? why boosting so high ? no other mods at all !

Should be 13.64psi as standard.
I reckon you got a Jap Map in there.

1.28 psi is beyond control of the standard map sensor so fuel-cut must of been bypassed somehow.

It wouldn't suprise me if it was a Jap map as I have seen some ridiculous ones over the years.

When you take the ECU out, if the screws are easy to remove from the cover then you will most likley find a chip/adaptor in there. If it's a virgin ECU the screws are loctited and can be a bitch to get out.

the above should of read 1.28bar not psi (DOH!!!)
would of editted the post but edit seems to be throwing a wobbler.....

going to check now buddy !!! was busy as hell today and yesterday !

opened the ecu and it was a james hunt to get open ! (6k ecu) and nothing !:wonder: no daughter board or jap stickers etc etc.. as it should be !:confused: could it just be peaking at 18 psi and dropping back cos its decatted etc ??

i've about the same readings on my boost gauge, sti III v-limited, about 1.25bar at full trottle!!
don't think it has a chip or something like that, but have a cat back blitz nur spec and turbo time.:eek2:

i hope its just flowing well ! :) its getting a downpipe fitted too(was supposed to be done yesterday) and i hope it doesnt go much higher !! just faster !:norty:

Shouldn't be boosting that high even with a deact.
Check the bottom hose from the boost control solenoid, to see if it has a little brass restritor in it. It;s normally just after the 90 degree bend in the hose.

The levels of boost you are reporting should be triggering fuel cut. Fitting the decat will make it even worse.

no fuel cut scott and i just done my k+n filter as the std one was guffed ! and wa hey ! fook me !! it does pick up better but peak tonight was 1.21 ! and downpipe isnt fitted still ! no fuel cut either ! just goes ! :wonder: no drama either ! i am going to do something with it during the summer. either apexi or one of your little darlings !
