not sure sorry. i have the older hks evc 3 and it works great set boost and thats all you need to do. no need for fancy screen and crap

hks evc

well thats why its spking youve taken away the exhaust restriction so now its easier for the engine to flow exhaust, which in turn drives the turbine faster, which makes more boost and makes it spike. i would suggest a good electronic boost controller. one that can only close based on whatever preset pressure is.

something is leaking or not correct for it to spike that much the stock actuator wont allow it to hold that much pressure i would suggest checking all the hoses and tubes what exhaust?

Depart time updated, we are leaving at 8pm sharp. If you arent there then youll hav to play catch up

when the throttle is steady on cruise it looks at the 02 sensor valve and trims fuel to reach the ideal afr of 14.7. so if at cruise the afr is 13.2 cos the tune is rich when you are crusing the ecu will look at the 02 sensor. the 02 sensor will report "rich" so the ecu will begin slowly leaning itself out until the 02 sensor reports "lean" and then it will keep bouncing between the two, 14.7 is ideal afr for cruising. on stock ish powerfc maps and closed loop feedback off your economy will suck the wang. but its not the be all and end all of economy. i have 02 feedback off on my FC and im getting good economy, but i spent considerable time tuning cruise afr's with a wideband sensor on the street. its known as closed loop as it enters loop operation with closed feedback from the 02 sensor

yeah installed is zero, plug and play takes 5 minutes to install. self idle learn procedure takes 20 minutes to do by yourself and your away. i would expect double the load points and features from the haltech for its price

Bring some to deca, for those that are weak

datalogit reads all the sensors the powerfc does, so if you have a working boost readout on the hand controller it will appear in the datalogit logs. if you have no working boost sensor, then boost will appear as 0 all the time

piggybacking one of the two map sensors onto the boost kit sensor doesn't sound safe. i wouldnt want to try that. it might go bang and fry an expensive ecu. not sure where u could get the denso one from. www.nengun.com has the boost kit in bits if you want that, as in the legit apexi map sensor

the charged me 350 odd to pull my diff out inspect it, flush it and put it back in so probably about the same to swap centres

you just drop the centre bit out, the rest stays in. i recenently had my diff checked by nothern differentials in thomastown/sommerton. they are pretty good guys and know their shit. bill is the main guy

The two map sensors are manifold pressure for the guesstimation of airflow to work out engine load. Whilst they look at the same base item it wont provide Boost on the hand controller. The powerfc FAQ (in my sig) tells you how to hook up half the boost control kit to get boost displayed on the hand controller, it lists the denso map sensor part no also

go the local delivered, will be easier

agreed f6

The first and singlemost thing I can recommend. STOP PICKING RANDOM PARTS FROM MID AIR. do a search, keep searching and keep reading. have a look at the rb25 turbo upgrade thread. read what others have done. search for things like: 2835 by user grepin 2835 by user freebaggin hiflow by sydneykid gtrs by user thizzle

9k is a suitable budget for 30,000k's

no they are the same physical size. different colour label and plug. it measures more air despite being the same voltage range. its calibrated differently to the rb20 and rb25 afm's so at 4v its flowing more air than an rb20 afm at 4v

sounds expensive

the left over fluid is for sale http://www.skylinesaustralia.com/forums/in...howtopic=131160 as i dont need it anymore

Hi, I have approx 3 litres (ish) of Castrol Transmax Z fluid for sale. I purchase 4 litres of it today for $65 and have only used about 400mls of it. I used it to flush and top up my Gtst with the vspec a-lsd system in it, which uses the same fluid. I am in melbourne and pick up would be easy. I goto the sau vic meetings each week so I can bring it then. My price for the remaining fluid is $40

well high load lean is great and all but the stock narrow cant tell you anything outside its scope of 14 lambda. so if you lean out to 16 it wont even know

1. undo nipple next to the a-lsd pump 2. a bit of fluid trickles out 3. turn car on, left a-lsd pass diag 4. run pump manually 5. wait for trickling to finish 6. check that a-lsd resivour is empty 7. close off nipple 8. put in new castrol transfer max Z 9. top up to max line 10. put cap back on 11. go for a drive 12. experience correct active lsd locking operation the diff operates like a brand new locking diff now. it locks each time perfectly in computer mode and does prefect gliding. no need for the manual switch anymore as it operates spot on with the a-lsd puter driving the show. i am amazed at how much of a difference that has made to my car. it seems there was a big air pocket in the system and bleeding it has taken that out. im bleeding it again to cycle out the bad fluid. the fluid that came out was brown/orangey. the new stuff is a new bluey/green. so ill flush the current mix out again and hopefully have a close as possible 100% fill of castrol transmax Z. the gtr transfer case uses the transmax Z stuff which is actually automatic transmission fluid

they make them because they are there to make money and poeple buy them. an af guage is useful with a wideband sensor, not a narrow band sensors. all cars have a stock narrowband sensor which the ecu uses for fuel economy saving. its useless as a "rich" or "lean" indicator to know if its safe or not. if you want to monitor if your car is safe ideally you want to: exhaust gas temperature guage wideband 02 sensor with af guage
