Faq: Apexi Powerfc - Frequently Asked Questions

[Hairball]

Has anyone had much experience with using the FC Commander Pro Software?

I would love to get some technical assistance if you have.

Software was purchased, installed, registered and connected OK to my ECU without a hitch, however when I tried to connect it to two other 'pexi ECU's it failed to establish a connection.

I spent a fair bit of time trying to nut it out and it appears to be just the other two ECU's that I have an issue communicating with. So I guess my question is: Is the software only licensed to run on one ECU, or is it the two (non-communicating) ECU's being of a different model/type?

The software works seamlessly with my R33 GTR, so my belief is that the issue lies with the fact that the R34 GTR and R34 GTS-T's Apexi ECU's are not compatible with the R33. The only way I have to determine if the problem lies with a license issue or with a software version issue is to get another R33 GTR with the same ECU as mine (about as easy as it sounds).

This is where you come into it . In your travels have to come across the quick answer to this question?

this is certainly possible - have a look at the product matrix to find out if its supported by your version of FC pro & cable

alright i have now installed a power FC into my car and im having a issue im not sure if it due to the power fc or what

when i give my car the boot then take foot off the accel and put on clutch now and again my car will stall but soon as i let foot off clutch starts up again (like push starting it)

has anyone had this issue mind you it is in a evo so i doubt alot of you have

[paulr33]

hi robert,

this can happen if you dont do the self idle adjustment properly

can you confirm you did this correctly?

also i assume you have std bov etc and not an atmo unit ?

[NickR33]

does anybody know why I just had a retune and now the H/C screen isn't coming on?

I will ring the tuner and ask but just thought I would ask here first in case its something really obvious

[paulr33]

if its blank unplugged or loose cable

if its locked on the apexi logo wrong hand controller version

if its locked on a blank screen (but lit up) then loose connector, damaged connector or damaged hand controller

[NickR33]

I'm a douche... it wasn't plugged in:/

[paulr33]

no worries - all good

Hey,

I have a RB26DETT FC D-Jetro on its way from nengun and i have the field one touch connecter from greenline. A mate (the_mafia) is re-wiring it to suit my rb20det r32 gtst. He has done the conversion with a normal fc but never djetro.

My current mods

3" turboback

2.5" split dump

GCG Highflow Turbo

Turbosmart boost T

HKS Pod

Walbro Fuel Pump

Fuel Pressure Reg (going to be removed with ecu install)

Splitfire Coilpacks

Plazmaman Forward intake plenum

hybrid fmic

plazmaman piping kit

when ecu goes in (already have waiting)

GTR injectors

3-4" intake pipe

Now we have extablised i can use a vacuume line from under plenum and T off to 2 map sensors. What im wondering is i have read the map sensors need to be spliced into standard loom for airflow meter... so do we cut off plug, and just splice 2 new wires to each existing wire in the airflow meter loom.

Also air intake temp sensor. Where does it go... have been told this will make tune much easier. So basically is there an aftermarket option (bosch) or something that is cheap or should i source one new from nissan?? Will i need to weld any nipples onto piping anywhere or what?

And now for the acc valve. I have a hose going from that to my intake pipe (behind my afm) for now and i have been told i can just put a little breather filter off the valve and leave it at that with the fc... and it will work fine, is this true.

Factory oxygen sensor... should i replace it... i have been told they should be done every 40,000km and my guess is mine is still factory one. I have also been told i wont need it with djetro and it would be a waste of money... in that case can i plug off the dump pipe or should i just leave it or should i replace it.

thanks alot if you could answer these questions. Yes i have read the faq but i could not find too much relating to my issues in depth.

cheers, Leon

Question

*2x R33 GTST Series 2 Skylines

Car A: Has Apexi PFC and Z32 AFM

Car B: Has stock ECU and stock AFM

How simple is it to swap these 2 items between cars as car A is going to be sold and taken back to stockish state. Can we just simply unplug the wiring harness from the ECU's, swap them around and plug right back in and should be fine to drive?

*Cars A and B both have stock turbo's and almost identical modifications (FMIC, 3" turbo-back, fuel pump)

Also, unplugging the PFC and moving to another vehicle... with this retain the tune or reset all settings?

Cheers,

Ryan

if you do a direct swap one for one it should be ok - the worst is it wont idle, if it doesnt then youll need to do DATA INIT to do the self idle adjustment (you will loose the tune). the tune is always retained even with power off and unplugged. its only erased if you do DATA INIT

[SKYRYAN]

Thanks Paul

We are going to attempt to swap them around this afternoon. If my car doesn't idle I will check your FAQ for info on the DATA INIT. Great work!
