type r boost question
#1
all,
what is the standard boost pressure for a STi 5 type r, i am currently running and holding 1.2 bar and it peaks at 1.25 - 1.3, do we think it has had some ecu work done? in all honesty i dont know where to start looking and it doesnt have anything obviously out of place under the bonnet? where would i look to see if the ecu has been fiddled with ?
many thanks for your time, dave

ECU is in the footwell of the passenger seat.
Check for the obvious different brand, or additional piggyback units connected to it.
1.3 is definately a little high for standard.
1.1ish on a vaguely accurate gauge , is nearer the mark for a stock V5 Type R.

1 to 1.1 standard 1.3+ deffo sounds like an ECU change !
edited to add - hope you have a knock and lamda sensors such as knocklink..

Type R's sometimes seem to run more boost than standard STI's from what i've seen tbh.
Gixermans STI Version 5 was running at 1.4 peak and 1.2 held on a standard ecu so I would'nt worry to be honest, his car was fully de-catted.
Wheras I see 1bar on my STI Version 5 4 Door on std ecu.

I would be worried about boost spikes over 1.2 bar on a Type R on their original ignition map with a decat and no knocklink. Midrange boost target is 1.08 bar.
There may be a small difference in restrictor orifice for the shorter geared cars, can't remember.
Also your boost gauge could be over-reading, especially with a relatively high held boost figure, the ECU tends to pull it down pretty sharpish to 1.08 bar where it can after the initial spike.

i am currently running an unknown brand japanese fitted exhaust which is the standard down pipe but a 3 inch bore centre and back box, with a nice titanium tip ! i have the standard air bow though and notyhing else that i can see has been changed.
i still havent been able to locate the ecu though if anyone could show me a pic or give me clear instructions? i have had the carpet up today and a mooch around the dash area on the passenger side but still no sign ?
many thanks for you help so far dave

simb 2: No, its either not producing or losing boost somewhere.
Going off JB's post, they should produce 1.08 bar. Mine is runs the standard ecu and I read aprox. 1.1 bar. If your guage is reading correctly, your down 0.3 (about 4.5psi) You will be considerably down on power. I would get it looked at.

alas, no its the original ecu, well no indications to say its not anyway? ill just have to wait for the next rolling road day to try and find out what kind of power figures it is putting out >?
anyone know what the factory bhp is and if so what the quoted 0-60 is ? i must say i am enjoying this type r lark !

Factory figures are 276bhp(280PS) and 260lbft (394Nm).
My experience is that most standard Type R's still struggle to get more than a genuine 270bhp (210@wheels ish) and 240lbft without a remapp on an accurate dyno..........

Gedi, my boost gauge reads 11 PSI on full chant. Whether she's losing power I don't know, it was rolling roaded at 301BHP - 230BHP at the wheels and 240ft/lb torque, this was a couple weeks back.

All I know is that the gauge was supplied and fitted by a scooby tunning company and reads 11 PSI on full chant, the rolling road printout shows 0.8 bar with the power figures stated, confusing I know. Will prob get the gauge looked at when its in for an oil change.
