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:

    • Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL
    • Could be falling edge/rising edge is set wrong. Are you getting sync errors?
    • On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.
    • Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
    • Nice....looking forward to that update
