even though the Advan GTR started as a GTS4 its had a full transplant of all the GTR gear. Even most of the panels are GTR so its more a GTR than a GTS4. The only GTS4 part I can tell really is the sunroof.... then again I don't know a great deal about it.

The japs seem to like the Profec better but then again the Apexi has the nice rice factor :)

Also if you plan to get a PowerFC the AVC-R is an easy option.

From a practical perspective I have a preference towards the Profec B.

Sure the AVC-R holds the title for the most bells and whistles but in reality, how many people ACTUALLY have time to utilise all its features when driving....I tend to spend more time looking where Im going.

The other concern is that the AVC-R is only a relaible form of controller up to about 1.5bar...beyond that and its accuracy is seriously compromised.

I suspect this is why most of the big name Japanese tuning houses are not using the AVC-R in high output cars.

my advice is get niether i know this will met strong criticism but hear me out:uh-huh: If you have a standard turbo get a dual stage turbo smart if you have a bigg turbo set the boost through the wastegate. Now i just havent said this blindly ive had some experience on both and from talking to an expert in tuning this is my conclusion. you see if you do a dyno run with max boost max everything the computer sets this when you run lower boost it only resets to an extent so i believe your not saving that much extra juice or whatever by running it at a lower boost you better off running your car the way its tuned all the time if this means 15psi then thats it. I have a profec b but im goin to take it off my GTR n put it on the r33 (cause my mum drives it) cause i believe that extra wiring hassle with calibration and weight are not worth the small amount of fuel i would be saving!!:( Just my 2c worth. And i know its mainly the ease of just changing boost that is the luxury just something to think about if your tryin to decide between two part for your car a fmic or a profec b for instance:rolleyes:

bahaha xrsist..

but you aint making any sence...

your telling me to just run what its tuned at (max boost) all the time..

then why the need for a "dual stage" bc??

besides a EBC is much more accurate ...

but the choice between the EBC and a FMI is a good point..

- hahaa.. yea. one of those long days at work does that to you.

Basically what s13drifter is saying is that he would spend his

money on a fmic first before getting a EBC to keep detonation

at a minimal. You do want your engine to last don't you.. or have

you got conrods,cams new head and stuff lined up already????

If you really want to boost it, just buy a stage turbosmart or something for now.. It won't be hard to sell later.

Now back to the topic... If you really want the EBC, then by all

means get ProFec B... :uh-huh:

i agree with xrsist that the profec b is probs better unless you are goin to go to a power fc then the apexi is a better option. The reason that i suggested the daul stage bc is because it is cheap and if you really do need to use 2 different boost settings in your car. I know that they arent as accurate for curving boost spiking but unless you are willing to re callibrate your ebc often they arent as efficient in stopping boost spiking as alot of people think. Im not against them i just thought id mention other options for you Hype, cheers.

The only GTS4 bits left are the shell and chassis....

And I would agree with SadisticRage, the AVC-R isn't good above 1.5bar..... go with the ProfecB

Hype the apexi is better with a power fc cause it can be intergrated into the power fc as they are both Apexi. Im not sure on this but i think the power fc might have a extra pin in for the avc-r and maybe a sub menu through though the computer that recognises that you are using the boost controller. Can any one varify this i could of been told ****:eek:

      R33 persistent issues. P/steering and lag/misfire

      By GTSBoy · Posted

      What are we supposed to be seeing in the photo of the steering angle sensor? The outer housing doesn't turn, right? All the action is on the inside. The real test here is whether or not your car has had the steering put back together by a butcher. When the steering is centred (and we're not caring about the wheel too much here, we're talking about the front wheels, parallel, facing front) then you should have an absolutely even number of turns from centre to left lock and centre to right lock. If there is any difference at all then perhaps the thing has been put back together wrongly, either the steering wheel put on one spline (or more!) off, and the alignment bodged to straighteb the wheel, or the opposite where something silly was done underneath and the wheel put back on crooked to compensate. Nut there isn't actually much evidence that you have such a problem anyway. It is something you can easily measure and test for to find out though. My money is still on the HICAS CU not driving the PS solenoid with the proper PWM signal required to lighten the load at lower speed. If it were me, I would be putting either a multimeter or oscilloscope onto the solenoid terminals and taking it for a drive, looking for the voltage to change. The PWM signal is 0v, 12V, 0V, 12v with ...obviously...modulated pulse width. You should see that as an average voltage somewhere between 0V and 12V, and it should vary with speed. An handheld oscilloscope would be the better tool for this, because they are definitely good enough but there's no telling if any cheap shit multimeter that people have lying around are good enough. You can also directly interfere with the solenoid. If you wire up a little voltage divider with variable resistor on it, and hook the PS solenoid direct to 12V through that, you can manually adjust the voltage to the solenoid and you should be able to make it go ligheter and heavier. If you cannot, then the problem is either the solenoid itself dead, or your description of the steering being "tight" (which I have just been assuming you mean "heavy") could be that you have a mechanical problem in the steering and there is heaps of resistance to movement.

      Little update  I have shimmed the solenoid on the rack today following Keep it Reets video on YouTube. However my steering is still tight. I have this showing on Nisscan, my steering angle sensor was the closest to 0 degrees (I could get it to 0 degrees by small little tweaks, but the angle was way off centre? I can't figure this out for the life of me. I get no faults through Nisscan.

      The BES920 is like the Toyota Camrys of coffee machines. E61 group head is cool, however the time requirements for home use makes it less desirable. The Toyota Camry coffee machine runs twin boilers and also PID temp control, some say it produces coffees as good as an E61 group head machine.

      One way of putting the fuel surge idea to rest, is that even when in neutral/clutch in or free revving it still has the same issue, it can’t even get to limiter (7800) so to me that says it can’t be g force, I’m not trying to argue I just want to find the f&$king issue 😡
