got a r33 gtr with power fc, thing was pullin 257kw at the wheels then the next time got it tuned they had to bring it back 9 degrees cause it was pinging of its head. so as a result not getting i was much power now its pretty much back to standard. not naming anyone but when i asked what was the reason for it, i was told that they didnt no:-( its still driving ok from what i can gather but just wondering if anyone has any opions on what might be going on?

going to see someone about it next week but would mind gettin a few opions as i have not much of an idea. thanks:-)

did they adjust the CAS or adjust the ignition timing on the IGN MAP on the hand controller?

adjusting the CAS is braindead and the lazy way, and it affects the whole tune

but if they did it on the IGN map its ok. what fuel are you using?

cars usually knock different on the dyno vs on the street so its normal to see some knocking on the street after a full tune

i didnt get much feed back at all, he just said dont panic drive it for a while and see what happens. considering he is spost to be one of the best you think he would have some idea. im was using 100 octane but have to use the 98 and im putting the octaine booter in it but its not really makin much diffrence. anyway hopin this new guy i will take it too can sort it out. this shit is depressing. feel like im drivin me mums collrola sometimes:-)

so you got it tuned on 100 and now your using 98?

no wonder its knocking, you need to get it retuned on 98, the timing will be heaps different

until you get it re-tuned on 98 baby it around, backdial the CAS or use the powerfc temp ign adjust (covered in the PFC FAQ in my signature)

the PFC temp ign adjust is the quickest way to temporary reduce timing across the whole map

      33 GTR Broken front wheel knuckle

      By R32 TT · Posted

      Just had this happen to me too.  R32 GTR.   Also broke "just before going out onto the track" - someone up there is looking out for us... Very scary since I was about to do a narrow street course with zero run-off and curbs everywhere. Many people on here upgrading to billet uprights and R35 bearings?   Or buying new OEM knuckles?  I am not keen to replace with another s/h 30 year old fatigued part.

      Coolant leak?

      By joshuaho96 · Posted

      Top off with distilled water and see what happens. If you keep losing coolant then you know to start looking.

      Quieter performance exhausts (or muffler add-on options)

      Nope.    Grab a varex and turn it down as you get close to home, win win?

      Quieter performance exhausts (or muffler add-on options)

      By f00stx · Posted

      So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
