Morning all,

I am currently up to the stage of modding were i need/want more boost. i have a turbo back zorst, pod, Greddy FMIC and BOV.

Ive checked out the Power FC's and they look like a tidy unit capable of almost anything. Would i be better just buying an APEXi boost controller for $600 rather than the Power FC for $1000?? would it be worth the extra $$'s for the added features that it offers?

Im not wanting to turn this into a full blown drag car, but i will probly mod further into next year.

Absolutely dude... buying a boost controller limits you to what you can do. Yeah sure you'll have boost on tap but you can't play around with the vital things which a Power FC will allow you to do.

Save your penny's and get the FC. They are a plug and play unit and have 101 benefits over a run of the mill boost contoller.

Especially if you are looking to mod further, because the FC will allow you to change things like your and air/fuel ratios etc vital when putting more fast bits on your car.

The AVC-R wont give you anything near what the PowerFC will.

Just buy the boost controller add-on for the PFC, only a few hundred more.

I thought that i would be able to dial up the boost from in the car with just the Power FC. Im assuming that the Apexi AVC-R boost controller allows this option on its own but nothing else. I'll check out some prices on the add-on. I was hoping to have it all for around the $1100 mark roughly.

If i was to do no more mods to the car after this would the PFC stil be the better way to go? Would the extras stil be a benefit to me?

The PowerFC is an ECU

not a boost controller. You need to purchase the Boost Contol solenoid etc in additoon to the PowerFC to make the PowerFC able to control boost

this is covered in the sticky thread in this section if im not mistaken

Don't bother with the Apexi boost soleniod kit, the factory one works fine. Just buy a power FC and get someone who knows what they are doing to tune it. Put the few hundred you'll save into dyno time.

BBGTR, The RB20DET's run a basic wastegate setup, so an boost controller of some time is required.

Buy the PFC then redrill the holes on the wastegate bracket so that it becomes adjustable. :) Not so much redrill but elong. If you have the cash go the pfc boost controller from nengun.

They are fairly cheap considering its a self learning boost controller. Unlike the Archaic adjust a duty cycle and gain type ebc. The self learning ebc's constantly adjust duty cycle to obtain the target boost pressure.

I've always wondered why they GTR's need to run an elec bleed system when they don't have a 2 stage boost like the R33's do.

Whats the 32 GTR's base boost pressure if you were to bypass the solanoid and run it straight off the actuator?

I'd just be buying an adjustable actuator and set the preload so you can run 13psi or so. Shouldn't cost more than 250. The r32 dosen't have the aggresive rich and retard strategy that the 33 has so you will make some decent gains from this.

Then save and get the power fc if you want to go further in the future.

About 7-8 PSI I think - like most factory springs.

Ideally i want to be able to dial up the boost from inside the car. If i was to buy an adjustable boost controller and then later add the PowerFC, i wouldnt be able to use the hand controller for it?? unless is was the apexi boost solenoid that i put on initially??

Being able to adjust boost on the fly is a novelty.

The RB20DET isn't exactly a boost monster where a slight flick of the accelerator instantly see's all its boost.

Even with the rb30det and a small motor its easy to regulate the amount of boost I make.

after 3 days and the novelty of being able to change your boost wares off.. i doubt your gonna be playing with it much :P

I think you're getting confused.

A boost controller is seperate from a ECU. The pfc is a stand alone aftermarket ECU.. which happens to be able to plug into a hand controller.

A boost controller will just change your boost..

So.. it depends what you want to do - retune the car or up the boost.

The PFC -can- control a boost controller solenoid, so in this sense it can work like a boost controller... but they are really 2 different things.

an adjustable boost controller is only good for a factory ecu, if you want high power or low power..

but I'd run high all the time and get a powerfc and tune it to it, ebcause if you tune any ECU to a certian boost, and you lower the boost for a "low mode" you'll f**k all of your tune up cause its tuned for higher boost..

Easiest way to do it, is get the powerfc boost control kit to control spikes, spool, etc etc and level your boost, and then use your foot to control boost...

Less throttle means less boost..... If you can't do that, then you're a danger on the road and you should sell your car and buy a push bike..........

    • Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
    • Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.
    • @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html
    • These going to fit over the big brakes? I'd be reeeeeeeeaaaall hesitant to believe so.
    • The leather work properly stunned me. Again, I am thankful that the leather was in such good condition. I'm not sure what the indent is at the top of the passenger seat. Like somebody was sitting in it with a golf ball between their shoulders. The wheels are more grey than silver now and missing a lot of gloss.  Here's one with nice silver wheels.
