Hi guys

searched these forums and the NZ ones, Problem is my GTS25T S1 runs fine on standard ECUeverything works in the car. Bought a Brand new PFC and took of the batt cable ,plugged in PFC -reconnectede batt turned on ignition, all I got was what I first thought was the fuel pump pulsing in the boot and the eng check light flashing like mad . the car would turn over but not start. the commander lights up and goes to moniter,settings,etc screen. but nothing is working. so I got on here and asked a few guys. got out the mu8ltimeter and checked every pin out voltage against the manual i downloaded ,all fine next stage hunting through all the auton stuff(yes mine was origanally auto).

spent the next day taking then dash apart and unwiring the alarm (freindly suggestion from member) no luck. finaly online I found a british gtr site where someone said there was a fuse problem on their gtr.I DO NOT BELIEVE IT!!!. in car fusebox ,left bank of two six up from bottom is an engine control fuse, its ten amps which i am thinking is fine untill you add the extra a PFC needs to save data etc. the standard ECU dosnt seem to mind at all if this fuse is blown but the PFC no way hosea. anyway just before I was going to send it back to Japan a fifteen amp fuse( why are they so hard to see in a skyline)and its fixed!! yayyy!!

yes thats right but thats when the engine is running .it didnt even get that far.

and it wasnt so much flashing as flickering in time with the buzz from the boot which turned out to be a blue relay next to the battery ( i think this is the eccs one?) once the fuse was replaced its fine and the check light only comes on a few flashes when I cane it hard (either injector max or a few knocks) its off to get tuned on the dyno now.

      It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪

      And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil

      Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.
