  1. ok so the guage is in MMHG -7 is vacuum 0 is basically absoute pressure +7 is 760mmhg which is 1 bar or 1kgcm2 when you drive it will be around -500 ish when you floor it, it will build pressure to 0 (all cars do this, even N/A) then it will go past zero and start building boost pressure 3/4 up the guage is +5 or +500mmhg which is around 11psi ish the green area is vacuum blue line is around stage 1 boost - 0rpm to 4500rpm approx 5psi on manual GTST pink line is around stage 2 booost - 4500rpm to redline, approx 7psi on manual GTST the auto runs approx 5psi on stage 2 boost
  2. the stock guage on the dash (turbo icon inside RPM tacho) should swing past 0 mmhg on the guage (which is half way) after about 2 seconds of accelearting anything past 0 is "boost" it should goto around 3/4 which is around 0.75kgcm2is after 4500rpm and before that it should be around 0.5kgcm2 if its a manual gtst the stock guage is in MMHG but its close to kgcm2 so its ok as a base measure
  3. yeah whats the point of all the ODB2 if its all just display info and flashy read only things? pointless, get a hand controller or some form of tuneable interface and away you go
  4. just a VLT
  5. powerfc has a hand conrtoller which is essentially the same thing
  6. nothing to measure really, all AFMs are 5v but they have different resolution, ie different phyiscal flow is different voltage range in the ramp
  7. looks ace well done and nice ride
  8. measure them is the best way but do you have std intake piping and a std ECU or aftermarket intake ducting and standalone / aftermarket ECU? ie if you have aftermarket pod or ducting kit and standalone ECU you might have Z32s which are 80mm if you have std piping and std ECU then you have std GTR afms which are 65mm so physical size and look are ways to work out what ones you have
  9. it sounds like you have Z32s or nismo's AFMS and you've ordered stockers so it wont work and it would be very angry, please be careful you dont fry your new AFMs post up pics of both please are they both 65mm?
  10. yes try just logging one thing instead of lots of things there is no logical reason hand controller would see knock differently to datalogit and make sure you arent using both at the same time as its a shared bus
  11. nokia 3210
  12. would you be willing to risk your 34R motor on it ?
  13. a lot of haters in here i see i think the idea is great if you have an N/A car and want to turbocharge it and have no room etc to fit in the normal method is it better than N/A Yes? Is it better than doing it properly in the engine bay? No. but if you have no choice, then it is suitable observations from the video its only 5psi but twin turbonetics, such a waste for an expensive setup!!!! i dont really like the spool up noise, i prefer my GTST turbo spool up noise from the engine bay to be honest when you do the rear turbo install there has to be more lag and you can see from his boost guage it takes a while to wind up sure its twins so you would expect that, but even from that STS thread in the FI seciton, you can see on his guage, there is noticable lag i think when most people think of the rear turbo setups they expect 5 seconds lag whereas on an engine bay related setup its usually instant spool up i think in reality the rear turbo setup would be sub 1500ms lag and in the engine bay setup it would be sub 500ms lag i say time when you open the thorttle full to time the turbo charger starts adding positive boost pressure so i dont think it's as bad as eveyone believes
  14. johnoo is bang on but also when you are viewing hand controller knock is it on the street or dyno and likewise with datalogit, is on the street or dyno i found everytime cars knock differently on street with the owner driving them vs the dyno and dyno operator i think this is because the owner drives it differently to the dyno simulator and also the owner usually changes gears differently slightly etc so are they both in the same identical conditions??
  15. covered in the PFC FAQ the datalogit and hand controller should not be used at the same time. this is because they share the same bus and bandwidth from the powerfc that is, each data cycle may be missed by one and the other. so cycle 1 knock of 40 daalogit see's it, but hand controller doesnt, cycle 2 hand controller see's it and datalogti doesnt its fine to use both to just play around etc but if you are logging and tuning you should only use at at a time, and not both as it's a shared bus and was never designed for dual devices reading data at the same time
  16. nah sorry grant i couldnt make it i had to wake up with mega hangover and then clean up after a party at my place is your car the WBW white GTR ? looks sweet
  17. looks ace and well done to all those who helped out sometimes you dont want to have 40000 cars so a small number is great as well some nice looking rides there too, that 34R is porn and ash your new ride looks ace good work team
  18. what a great night so knackered
  19. i brought a seiko one , but i didnt work so dont bother, just buy the EL organic hand controller instead
  20. its unlikely the avc-r would reset itself, the tune and tune data is stored in NVRAM so even if you nuke its power source it wont loose the data the safc, powerfc, rsm etc are all like this, their tune and data is in NVRAM to prevent magic erasing and resettings its more likely a mechanical vac line or someone has been fiddling
  21. thanks dudes time to retire
  22. arr squiddy whats going on
  23. i think he means a bog stock RB25 rebuild back to factory specs, compression and performance i too am wondering total $ for this type of reubild, my rb25 has 230,000 on the clock, how much to set it back to 0
  24. that duke and cube are complete ass
  25. yep the way to do this is to tune car properly. either a stand alone, a remap, nisttune etc the differences between an untuned GTST and a tuned GTST maxing the stock turbo is amazing untuned the GTST feels pretty light on power and just plods along with progressive but light midrange when it is tuned on it's knees and you dial in lots of timing everywhere the GTST really comes alive im able to keep up with almost any car on the street and managed a few 0 to 100s in 4.8s so before you sell up or plan mega $$$ on turbo's etc tune the car to its max and you'll be surprised
