Hey,

Power FC is locked since its last tune by the previous owner. How do I unlock it? Do I need the special software or can it be done via the hand controller?

There's no power fc tuner here in rocky and I wanna upgrade the afm's.....

Cheers,

Chris.

Thats very interesting to know .

Is it only the fc's that croydon have tuned or does this happening when with every fc that has been locked?

How is croydon able to lock it and then when the fc is accessed by another datalogit or axcel software it get's reset to initated setting?

Not with mine and FC-datalogit; mine was last tuned by them about 3 years ago and I unlocked it after a hardware change about 2 years ago.

Maybe they're doing something different now...

this is a bug within FC-Edit itself, its not able to "see" the values so it overwrites them with its default when you hit update

this is common and very obvious with the injector settings, they get scrambled when you unlock it

i think its also different for different verison of the FC-Edit and PFC models, ie RB25 mangles the injector settings

and say RB26 may mangle other stuff, its just interface / validation bugs in their code (datalogits)

you would be able to unlock / relock a PFC with no dataloss with the correct sequence and code (ie: apexi FC Pro)

croydon is able to lock it as they have the datalolgit software, which you can lock a PFC tune

it gets "reset" when you unlock it due to an interface bug, its not croydons fault you have to reset it, once unlocked

croydon lock PFC tunes i guess to "protect" the user from doing something stupid on the hand controller

i guess that defeats the point of a stand alone engine management system, to allow you to manage it

nah it doesnt, should just be able to save the tune, then uncheck the "protect" ticks in settings 2 screen. i have a few customers come in with locked PFC's.... i also lock them on customer request as many have 'fast and furious" fingers and dont trust themselves... :D

      Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
