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

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:

    • Hi 🙋‍♂️. Just bought my Unicorn but the interior need some minor work so it would match my expectations ;). I noticed it is hard to get used oem floor mats in good condition so i started to dig if there's any chance to buy set of new ones. I found two websites - nengun and amayama and it looks like one can still buy factory new floor mats in Japan, but thers a small issue. Some mats (i assume genuine, oem ones) are marked as G4900 and these are "discontinued". The ones you can buy are marked as G4911 but i have no idea if these are also oem, made by other producer or some lower quality replacements that looks entirely different. Can anyone help? 😃  P.s. there is also some strange indication - 0V005, 0V015 and 0V505. Any idea what does it mean? Would appreciate any help with this 🙏
    • Hi, Marek here 🙋‍♂️. I finally fulfilled my longtime dream - recently bought Stagea and now waiting for it to arrive in Poland. There's only few of these in my country, and one of the owners  recommended mi this forum as a source of all the info i'd need since now i own one  so here i am.  
    • Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though
    • and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.  
    • Oh, you are right. But, in Australia E10 is based on 91RON fuel and ends up being 94RON. Hence it being the cheaper option for economy cars. The more performance oriented cars go for the 98RON fuel that has no ethanol mixed in. The only step up we have left then at some petrol stations is E85.
