Power Fc Lost Tune?

[johnnyt]

Hey guys had a short circuit which fried the power fc, took it too petroject and they repaired it..

just want too know wether i would have lost the tune from the ecu and wether there is a way to check via the hand controller?

car is a r32 gtr with t04z running about 550hp

cheers

Depends what was fried mate.

Do you have aftermarket AFM's or something?

That's super easy to check via the hand controller

[johnnyt]

yeah not sure what blew inside didnt get a report or anything with it.. just a $340 bill haha

yeah z32s

I forget the exact bloody menu's to go through to check lol, it's been so long since i've seen my own H/C

Someone else will know, but that's probably the easiest check.

Honestly though I'd take it for a dyno run just to make sure everything is OK after the repairs and so on.

setting > airflow > see if vg30 is selected or not

[johnnyt]

just checked hand controller

setting airflow and then the darkened line is over the vg30 option.. assuming this means its selected:)

started it and feels like it has bad miss. but im pretty sure this is due to running the standard ecu while testing to make sure the power fc was cactus..

will clean/change plugs and go from there i think

[JonnoHR31]

yer that means its selected. just keep a close eye on knock levels and make sure they're the same as before. and if o2 feedback is on have a look at what the injector duty is doing whilst cruising along, see how much it cycles up and down

[johnnyt]

another question boys..

my knock shows as a line, yet i hear people referring to there knock as numbers.. how do i change this?

also what knock is excessive for my application?

[JonnoHR31]

press the next button

anything over 50-60 is bad

[johnnyt]

cleaned the plugs but missing like a dog still.. new plugs tommorow

if the PFC has been reset to defaults the boost control kit is on by default, which means when you start the car, if you dont have the boost control kit, the engine check light stays on

so if you dont have the boost control kit and your PFC has been reset then your engine check light will remain on

the PFC has NVRAM which means the tune is only lost if the PFC requests to erase the NVRAM, kinda like flash ram

so with no power for years or sparks etc the NVRAM can retain its tune / details

when i fried my PFC and repaired it and booted the car up the PFC returned back to where it was (ie on the same monitor screen) and tune was still present

when knock is displayed under MONITOR, 1 CHANNEL, KNOCK you will get a bar graph, press UP displays top score in digital read out. Press RIGHT to erase the top score

cheers Paul, looks like all is good with the tune.. and thanks boys for the knock info
