Coming home from work this arvo, cruising on highway and car stalls, WTF

Tried restart, got dash lights, cranks, no PFC handset display, no fuel pump, checked all fuses - nothing

Checked PFC in another R33 - nothing, tried std ecu in mine and all ok except I got 750cc, gt3076r, z32 afm.

So does anyone repair or test power fc?

Can I check with nissan consult?

p.s. Anyone got std R33gtst injectors I can borrow?

there are places that repair them

you can also get apexi to repair it via nengun.com for official repair

you cant check it with consult so dont bother trying

open the powerfc up and look for any burnt tracks or damage, also smell for any burns

Bit off topic but I was just wondering, if I gave my tune from my PFC to someone that remaps stock ecus could they put my PFC tune onto a stock ecu??

It can be done but you need a nistune in your 33. That will cost about 700. Get your pfc quoted for repairs and go from there. your tuner should have your tune file.

^^ no each ecu code is unique therefore incompatible.

To OP the pfc seems to have lost the input resistor, i can do it for $80, but im sure you could get it done for far less locally.

provided they dont replace the main memory chip you shouldnt loose the tune.

i think thats the only thing no longer available... got two perfect pfc's... but the main "chips" are no good :(

seriously its a easy job to fix. far easier than replacing your injectors.

I don't think I filled my post enough but what I meant was the tuner can load up the Power FC tune, and mimic the data across to the Nistune ECU. You tuned tao's car I believe, he has given me screen dumps of his timing and ignition maps to provide my tuner. Even though tao runs a Nistune, the tuner was still able to get an idea of how things were running and how to setup the tune.

that was sort of what I was thinking, I believe Toshi does remaps to order, as in send him your specs and ecu and he sends it back tuned..

Which I would think is a less than perfect way to tune a car but..Surely if you gave him your previous tune data he could read it and mimic it so the tune should be close to spot on..

yeah as I said it would be a less than ideal way to do it..but say for instance you had a blown PFC and couldnt afford a new one..but you have your tune on file an old ecu laying around and remaps are only a few hundred bucks, it could just be enough to get you going again..

What is the chip? I work in micro processor development and might be able to find an alternative that uses the same protocol and mapping for the memory.

edit: Or are you talking about the micro itself? not the memory?

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.

      Skyline v36 350GT sedan hunting on idle

      By Robot · Posted

      Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣

      After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
