describe what happens please

does the inj/ign etc all show zero's ?

when you do DATA INIT, choose Yes (non default item) then press NEXT and then reboot the car

does it retain the previous settings?

i could post up default BNR32 maps, but it would by far easier to fix the root cause

if it wont DATA INIT, then its likely it wont save other changes too

so let's clarify and fix that up first - so as above, try DATA INIT the way listed above

The unit is used. the inj/ing settings do not show zeros. It retains what it was even when shut down and the battery is pulled and residual electricity is drained from the system. Changes I have made prior to the DATA INIT are retained.

when i DATA INIT and reboot the car, the settings are retained. Although after I did the 30 min idle it seems to idle better.

Thank for your help or at least trying.

this is a known issue, its covered in the PFC FAQ

view it from my signature and then look for "ECCS"

there is a known relay issue, and when the issue occurs, changes in the PFC tune are not saved at power off

which also explains why the DATA INIT doesn't clear, read it, and it tells you the correct fix

when you key off, the PFC needs an additional 1-2 seconds to write any run-time changes to NVRAM

if the install is shagged or the car isnt wired correctly, the PFC isnt given the extra 1-2 seconds required at key off

the end result is, at key off, the PFC doesnt get time to commit changes to NVRAM, so it results in a Read-only PFC or a "unsavable PFC" like what you are seeing

Thanks Paul. I had read your FAQ but didn't realize that the ignition needed to be cycled after the DATA INIT. I'll give it a try and keep the ignition off for at least a few seconds.

Sorry to bring this back from death, but a friend's evo VII is having this issue. Both Ign/Inj maps are filled up with zero's and any change i make gets errased as soon as i press the PREV button.

I only have the commander to tune.

How can i fix this???

THanks a lot in advance guys.

locked for sure.

yep as the others have said 0's on the hand controller for the maps is a locked powerfc tune.

find a local tuner who has apexi fc commander pro or datalogit and unlock it (simple tick box) and away you go.

i'll probably get from a friend a dattalogit box to use it with a laptop. But, how the heck do i unlock it? Is it a simple feature?

thanks a lot guys for your answeres.

yep

it's just a tickbox, no magic, no password

but sure to note, there are some things that are not restored when a tune is unlocked

be careful if this car has injectors that are non-std, and other key non std items such as AFM or map sensor

datalogit has some bugs where it mangles up the values sometimes when a tune is unlocked

i dont know why it does it, it just does its a bug with datalogit.

Thanks a lot paul. I'll post up as soo as i try this out.

I really like the power FC but i also really hate it to have this kind of problems.

I'm experiencing a problem now with a MY00 WRX that doesn't save when the key is off using the commander. It's not an engine swap, everything is stock (electrical) but i'm having this issue.

Once again, thanks a lot for the support mate.

Cheers.

    • Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).
    • Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers    
    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
    • Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
    • Hi All, putting the engine back together and everything is perfect except have this plug left over.. any ideas what it is for and where it goes? Is on cold side under the intake plenum *note not a stock plug, as everything has been modified Cheers
