Hey ppl on sau, I'm bout to purchase a apexi fc and controller for the first time and don't know much about it

what requirements do I need to it run smooth. A mate of a mate said the I need to change fuel pump injectors and all that stuff to have a power fc and running 10 psi boost i curently got 3.5 inch exhaust hybrid front mount pod

filter etc

so my question is :

1. What do I need to run smooth etc injectors what size what fuel pump

2. Where is the best place to have it turned

should I get all this stuff for it to save future tuneing or should the power fc run fine on stock components . I have seacherd this site bout apexi fcs and it hasn't answers my question yet so if any one can help me I will be muchly appriciated :)

cheers guys and gals

wouldn't really gain power by doing that running 10PSI

You would only need to change your injectors when they've hit their max duty cycle at higher boost & changing the fuel pump to supply the fuel requirements of the bigger injectors

at the moment to run 10PSI with stock injectors/AFM/fuel pump is completely fine.

you would only need to change the fuel pump if you're car is leaning out because of a faulty old pump

The ecu is just there to be able to tune and change settings there is no minimum requirement of what you need to run it, it can be tuned to run on whatever you, but if your car is leaning out hiting injector duty or afm maxing out than thats a different story you need to upgrade those things to keep going but yeah as you said 10psi with your mods keeping the stock parts and power fc will be fine , maybe just chucking it on the dyno to check you af ratios to be sure.

I know it sounds a bit rude and your money is yours to spend but why were you contemplating buying something that you don't know the basics of what it does / the purpose it serves? It's sounds like you've read a few mod lists and decided you want a Power FC because these people have made x amount of power and this is one of their mods. Highly recommend a little researching of how aftermarket ECUs like the Power FC work - this question you've posted is a good start but it sounds to me like something you just want because you think it'll bring you power. An issue at hand is that you will end up purchasing things that don't meet or are overkill for your requirements...resulting in some disappointment down the track. I recommend deciding on what your goal/requirement is and then asking yourself/others the question of how to get there. Cheers.

      Jacks that fit under GTR lips that can reach the subframe?

      By TurboTapin · Posted

      For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?

      Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed

      hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me

      Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
