yeah fair nuff, interesting point though i put 33r ones and its a direct swap but you sit noticably lower, like you said i guess it kinda makes more sense in terms of handling / cornering but never really thought of it that way

speaking of seats dezz did you find 34 seats you had sat lower in your gtst i found the r33r ones i have made us sit lower in the car just an observation

there is a clear distinction between brand related products on ebay and no-branded products on ebay the no-branded / foreign unheard of items are the junk items on ebay ie a HKS item on ebay is a HKS item a "performance pro" cam gear on ebay is junk

nope, there is none you would have to get FC Tune / one of the custom FC apps that rx7 guys have done or write your own either sound like a lot of work and time / effort. you can cut up the physical hand controller (pics in the Powerfc faq in my sig) and this may work also. it should fit in the display as well, but you wont need their screen and youll be stuck with the PFC screen instead

there is no off the shelf solution, you could buy datalogit and hack up that to allow your own communcation to the powerfc or you could get FC tune or one of other home brew apps and use them but they are very "raw" in development apps rx7forums has the main dev guys for powerfc front-ends all in all, i wouldnt bother hks camp looks spot on for what you want but it wont come cheap and wont speak to the powerfc

wish they made peanut butter museli bars still

on light cruise / driving at 100km/h i would expect 2 kgcm2 oil pressure my 220,000 rb25 with old oil in it has this pressure and its reasonble when cold it will peak past 4kgcm2 and slowly decay to 2 when warm 1 kgcm2 at idle is too low if oil pressure is critically low, oil pressure idiot light comes on if this comes on during heavy load id say your engine is toast if it comes on at idle, check the guage, and try an external tester/reader/mechanic

yeah an interesting point that i wonder if a) its the a/r housing size that makes it feel sluggish near 6krpm (stock GTST turbo) or b) if its the snout size / exhaust wheel that does that

i note the exhaust wheel and snout is heaps bigger but essentially the same A/R housing is retained - is it not ? how does this perform around 6000/7000 rpm?

i do agree the skyline is more fun when it pops and crackles a lot on light cruise / back off throttle

bubbling paint on the walls is a bit random, but re-painting is pretty easy im almost done my house, just got one roof section to do, all up nearly $1100 for everything, so just kitchen will be cheap

GTR is fine and should be prefect for around 250rwkw but they are as old as the car they come from, so keep that in mind vs a brand new bosch

scar non? in training today for 2 days

RB25DET + any ecu + no VCT = backwards

updated to include some help info and basic info, really need someone to do it in flash or something nice

updated 02/05/2010 - added "Basic Hand Controller functions - Online Emulator" which is a html clickable hand controller as a learning aid, first draft in HTML http://www.paulr33.com/powerfc-faq/powerfc-faq.htm#95

remain on topic

agree with skyguy if its all just changed after timing belt change which is a key change, logic says something has gone wrong here check the basics, check it with a timing light at idle

whats changed? has it always done this? when was it last "ok" ?

pretty please... it takes ages via html http://www.paulr33.com/pfcImages/menu.html

quality cannon ball run 3 chasing a white contach at the start and then it pulls over to a carwash and comes out pink some sort of stealth white cover on the car that washes off and then it goes onto the car carrying truck while being chased

yeha what mods have you got, you might be on the border line of R&R and it somes it goes over, some times it doenst

i disagree with blow randomly, there would be very few powerfc failures traced back to a manufacturing fault i would think more often than not its the user either jump starting their car with terminals backwards or not installing it correctly (ie harness not connected) i am yet to see a single powerfc fail due to a fault on the ECU all the ones ive had people ask me for help is when theyve done wrong jumpstart, mangled install, short circuited other stuff etc (like i did) it certainly pays to do your homework and check before you buy (as the case with anything)

A blowoff valve is a pressure release system present in turbocharged engines. Its purpose is to prevent compressor surge, and reduce wear on the turbocharger and engine. Blow off valves (BOV) relieve the damaging effects of compressor "surge loading" by allowing the compressed air to vent to atmosphere[1] A compressor bypass valve (CBV), also known as a compressor relief valve or diverter valve, is a vacuum-actuated valve designed to release pressure in the intake system of a turbocharged vehicle when the throttle is lifted or closed. This air pressure is re-circulated back into the non-pressurized end of the intake (before the turbo) but after the mass airflow sensor. A blowoff valve, (BOV, sometimes "hooter valve", not to be confused with a bypass valve) performs the same task but releases the air into the atmosphere instead of recirculating it. The blowoff action produces a range of distinctive hissing sounds, depending on the exit design. Some blowoff valves are sold with a trumpet-shaped exit that intentionally amplifies the sound. Some turbocharged vehicle owners may purchase a blowoff valve solely for the auditory effect even when the function is not required by normal engine operation. Motor sports governed by the FIA have made it illegal to vent unmuffled blowoff valves to the atmosphere.[citation needed] Blowoff valves are used to prevent compressor surge, a phenomenon that readily occurs when lifting off the throttle of an unvented, turbocharged engine. When the throttle plate on a turbocharged engine closes, the high pressure air in the intake system is trapped by the throttle and a pressure wave is forced back into the compressor. The compressor wheel slows rapidly and may even stall, and the driver will notice a fluttering air sound. The rapid slowing or stalling stresses the turbo and imparts severe turbo lag if the driver accelerates immediately after the surge event. n the case where a mass airflow sensor is used and must be located prior to the blowoff valve, the engine control unit (ECU) will meter out excess fuel because the atmospherically vented air is not subtracted from the intake charge measurements. The engine then briefly operates with a fuel-rich mixture after each valve actuation. The rich mixing can lead to hesitation or even stalling of the engine when the throttle is closed, a situation that worsens with higher boost pressures. Occasional events of this type may be only a nuisance, but frequent events can eventually foul the spark plugs and destroy the catalytic converter, as the inefficiently combusted fuel produces soot (excess carbon) and unburned fuel in the exhaust flow can produce soot in the converter and drive the converter beyond its normal operating temperature range. One way to mitigate the problem is to reduce the boost pressure, which reduces the required venting volume and yields less charge over-calculation by the ECU. The air can also be recirculated back into the intake, a typical stock setup for cars with an upstream MAF sensor. The situation can also be corrected by switching the fuel metering system over to a manifold absolute pressure sensor, a conversion that usually requires a compatible aftermarket ECU or piggy-back fuel controller. The MAP sensor monitors the absolute pressure in the manifold at all times and will correctly detect the change that occurs when the valve vents, allowing the ECU to reduce fuel metering accordingly. so according to wikipedia a BOV was developed as a work around to avoid compressor surge. compressur surge as we all know occurs when pressure past (after) the compressor wheel, exceeds pressure that the compressor cannot supply. that is, pressure exceeds far beyond what the compressor (and it's map) can actually supply. this is commonly observed with no BOV when the throttle body closes the built up pressure must go somewhere so it essentially collides mid air and causes the compressor wheel to surge. this human observation of this is the vl turbo tutututuutut noises. excessive surge on a compressor wheel can lead to failure. this was debated about 1.5 years ago to death and i still couldnt see (and i still cant) any logical reason for installing a factory bov as an emmissions "fix". i can however, see a logical reason why a factory bov is fitted, to avoid compressor surge

yep with RB25 and no VCT it will run like ass, tuned or not it will sluggish, doughey and lack response/crispness
