DIY Apexi Power FC Usage...

My R32 has an Apexi Power FC already fitted & tuned by a well respected tuner, however in the short term I would like to have a tinker with it..

I would like to:

1. Purchase the *correct* Commander hand controller for the unit, what details would I have to provide and can any vendors on here sort me out?

2. I would like to connect my laptop to the PFC, in addtion to the Commander for access and possible tinkering . What is the datalogic, how much is this unit, availability and how is it installed?

3. Ultimately be able to fit upgraded AFM's & Injectors. Is this straight forward enough task? Are we talking an all nighter? I assume the settings are fairly straight forward.

4. Anyone got a manual for the control of the PFC in PDF format?

5. The use of a wide band afr has been mentioned in other posts, how is this used in conjunction with tuning & will my cheap AFR by Lumenition do the trick or is the wide band defo needed?

Thanks, yes I am currently searching..

1) Their is not really a specific controller for you ecu but you can get one, or one that does all PFC's. You will need this to use datalogit. H/C = $350

2) Datalogit is a program that enables you to tune the car more extensivly, you can access features that you cannot alter on the H/C, it also has Dataloging hence the name datalogit !

3) This depends on what you buy, if you want a direct bolt in or if you want everything to look fancy and go top feed with custom rail etc. The cheapest option is to go sidefeed high impedance which is what standard injectors are. You can pick a set-up for around $900 - $1200 These are direct replamcements and because you have the FC they are easy to set the injector correction value's & ms.

Eg.

550cc injectors - the correction valve for these that have to be loaded into the FC will be.

370cc / 550cc = 0.67% as for the ms you will have to find the best spot it idle's on but around 0.8ms.

The only thing you will have to buy is injector O-rings as you can't really use the standard one's or you will get leaking problem's - not good. For time to do this job will take a fair while. - 6hr's i would guess with the standard intake plenum. With a Greddy plenum it takes around 2 - 3hr's :)

The AFM is easy to install aswel only 30min job if you know what you'r doing. You will have to wire in the new plug, Their is a wiring diagram on here under the tutorial section. eg: Z32 AFM you will have to select the VG30 setting on the FC command in the SETTINGS menu.

4) Yes their is a Manual for the power FC in english but its for a RX7. - Try seaching on the forums its been posted many times :rofl:

5) To use a wideband sensor it will be best to by datalogit as it has all the logging/monitoring system's etc... Datalogit cost around $600 from memory.

Hey, heres that manual

http://members.dodo.com.au/paul/skylinesau...nder_manual.pdf

i had my commander hand controller stolen during the import process and tried to use a mates but it didn't work, both are for R32 GTRs. so i'm also looking for a replacement one that will work.

Hi mate, I'm no expert on datalogit, BUT, I'm quite positive that you don't need a Power FC hand controller to use datalogit on a PFC. Also power FC hand controllers are model specific to a degree. ie. some HCs will work on various model Power FC, but there is no 'universal' Power FC HC as far as I know.

Thanks for that, food for thought.

The injectors... The sards are on the money but seem to be either single / twin. The other brands are more expensive.. I have looked for posts on the sards but most seem to slate as they are drag injectors and the spray pattern is not suitable for other uses.. not sure but I do know the price is more 'do-able' for me.

If I go with say the Sard 850's can I use the stock rail? Apparently a 'tight-fit'.. must do more searching on that one.

:cheers:

Thanks for the link. Must locate a comander. Would like that as well as the datalogic.

Thanks bud, think you are correct on that one. Lots of diff models.. strange as they all appear to be the same.. lol

A couple of things to note;

1. Since your log on is RB-26 I assume that means you have an RB26. They have top feed low impedance injectors. The most common style and much easier and cheaper to get than the RB25 side feed high impedance. You don't have to use a Jap "brand name", you can use Bosch, Nippon Denso, Jecs, Rochester etc etc

2. You can use a datalogit with or without the Commander. I use the Commander instead of buying many gauges.

3. The output of most wide band lambda sensors will plug straight into the Datalogit, they are usually 0-2 volts so nothing tricky to set up. On a street driven car we use Bosch sensors and run both a narrow band lambda sensor (for closed loop economy) and a wide band for tuning.

4. Commanders are specific, although the one you want is the most popular. This is the table from Meggala's web site

http://www.meggala.com/powerfcmodel.html

5. If you are changing injectors and AFM's (and expecting the sort of horsepower you should get) then there is no way you can do the tuning yourself, unless you do it on a track. You would end up in jail tuning the top end, high load maps.

My 20 cents worth:cheers:

      Blue slip

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
