R33 Gtst Issues

[skygt]

I have an external wastegate that is venting to the atmosphere and i want to connect it to the exhaust. I don't know if I should connect before the o2 sensor of after as I was thinking of the affect it would have on fuel economy and performance.

Also another issue I have is when I depress the clutch while driving the car stalls but only at a decent speed.

One more thing is that my exhaust temp light goes on after a decent drive and a bit of a heavy foot and car goes into limp mode for a minute.

Please help have had this car for 7 years and since power fc and wastegate just not enjoyable anymore

Thanks

wow kinda all over the place

ok replumbing the external gate shouldnt affect fuel economoy or performance (only if your exhaust is ass it might)

i would replumb the entry point after the 02 sensor

pressing in clutch at high speed and stalling is related to either idle RPM not set (ie too low or high) or you didnt do self idle adjustment properly (covered in PFC FAQ)

check the idle RPM settings and see if you can tweak these a little. if no good you will to do DATA INIT (copy your tune first) then do self idle adjust.

exhaust temp light is NOT used in powerfc

the exhaust temp light is RED

do you mean orange check engine light?

the powerfc users this when a sensor has failed or is outside range

when this happens view ETC, SENSOR SW CHECK. the dead sensor will be blackhighlighted

the powerfc, much like the stock ECU has limp mode for basic sensor failure

this is usually the TPS or AFM. either of these can trigger limp mode, ie rev cap at 2500rpm and shit mappings to save the engine from blowing up

I got carried away in my post.

The light was orange so it must of been engine , I saw it for a second and thought it looked different. I will check what you mentioned.

I cleaned the aac and afm and made difference in performance and idle but there must be something else going on too.

Thanks heaps
