Faq: Apexi Powerfc - Frequently Asked Questions

[ike]

Hi Paul

Just a question about using Datalogit on the PFC

Can settings be password protected so no adjustments can made at a later date with the normal hand controller .

Have been trying to increase my boost slightly but will not exceed 0.54bar .

PFC and EBC kit fitted and tuned by a tuner with datalogit.

I do not wish to return to this tuner if this is the case as we had a few issues.

Any help on this would be appreciated

Cheers

Ike

Good on you for getting and keeping this going Paul. Thanks.

I have a question I couldn't see an answer to. My HICAS light comes on after about 25km of normal driving. How can I check for a code like in the stock ECU? Is it pointless anyway cos it will just say HICAS error or can I get get more info?

Thanks.

hi adam,

the only thing i can think of would be to put the stock ecu back in and see how that goes.

if it doesnt fail on the stock ecu then pfc isnt doing something the stock ecu is

i had this issue with a-lsd in my r33. it was relaying the TPS signal to the alsd puter in the boot, but the stock ecu did

I would like a photo of the inside of an rb26 Djetro PFC please (anyone)

The FAQ link isn't working. Is this due to the site migration?

[OFENSV]

yeah will this be fixed?

Hey Paul,

I can't find it in you FAQ... Do you know if the Vairiable Valve Timing change over point can be changed using the hand controller?

Ryno

[paulr33]

original site restored, so we dont need the other mirror any more

the vct kick off point cannot be changed with the hand controller

the default is 4700rpm on the rb25 r33 model

My power FC crapped itself and needed to be repaired.

It kept on reverting to the base map and was not saving certain settings after a tune.

I had a loose HC port and apparently the chip was fried.

$400 later and I am waiting for the unit back from Access with a new chip, and hopefully all problems solved.

Unfortunately the tune was lost (bit disappointed they didnt save the tune before replacing the chip), however I expected this and asked my tuner to save the last tune before I took it in - maybe a good point for anyone that has to send theirs off for repair.

Can anyone confirm what this $400 would have replaced? I could not get a definate answer whether it was a major component of the unit (i am not very electronically minded) or if all I got was a small chip. The reason I ask is that I am just curious whether i essentially have a 'new' unit, or if most of it was retained and I have just a small bit replaced.

Cheers

if you've lost the tune data, then they probably replaced the nvram chip

this is the chip that stores your tune data and settings when the power is off

if its damaged or cooked it might not update itself with any new changes, which is what u were seeing

So this is a fairly small component of the unit?

Any chance damage to this would cause an unusually high battery draw? Usually my battery goes flat in 2-3 days, but since I took the PFC out to send it away the battery hasn't gone flat (the doors still open with the alarm remote after a week - they dont usually last that long)

I have been reading everyones guides(especially paul) and been a great help so far thanks heaps.

had my car tuned with powerfc and most things are fine but if i coast up to lights or stop sign in neutral the idle sits at about 1200rpm but then when i come to a complete stop it drops back to usual about 750rpm. anu ideas on what is going on? other than this idle is prefectly stable all the time.

cheers

[paulr33]

id say aac valve could need a clean the gasket could be toast and leaking a bit

thanks for reply. the only thing is that it only started happening after i put the power fc in...it jumps between 1200-1400 then drops back to normal. with stock ecu i could coast to a stop and idle was fine, thats what has confused me.

I got the power fc D-jetro on a GT-R R33 ...The stock load points are maxing out at 1 bar of the T88 ...Is there a way I can rescale the load points on the D-jetro power fc ?

It came with two apexi/denso map sensors

Hi,

The english user manual link does not work, any chance of finding another link? Want to get a copy of it!

[paulr33]

hi,

there is no official english manual. that link pointed to a english version for the integra so some of the features were irrelevant

ive managed to source english manuals for the fc pro software which covers all the main controls in the powerfc so there will be a big update to the power fc faq coming soon with all the legit english instructions
