Resetting R32 GTR ECU??

Hi guys,

Ive just got an R32 GTR, and it has the following mods:

- 3 1/2 inch Exhaust and front pipe (stock dumps)

- K & N hi flow panel filter

- Adjustable cam gears

- Simple bleed valve boost controller to 1.1 bar

- Almost new R34 GTR turbos

My car made 240rwkw.

This is all great, but it is running REALLY RICH!!!

Last night I took it out for about 10 mins to show my brother what it can do. I got back and the rear bumper is just covered in black spots.

Obviously it needs a tune as the standard ECU is making it really rich.

Will resetting the ECU do anything to this richness? As it hasnt been reset since its been in australia. And will this affect any of the cam/ignition settings?

I know Power FC is the way to go, but until I can afford that I want to try and keep my bumper a bit cleaner :D

I know something like a S-AFC is a quick fix, but ultimately its not gonna give me much more power I think.

thanks.

Just want to upgrade eventually to full ECU to get a bit more power across the range before i put in another turbo, but that might be a year away. Mine needs a proper dyno tune I think and the S-AFC adjusted (or something else looked at) as its not running great at the moment.

Anyway..getting off topic...back to it.

Guys, if I reset the ECU will it do anything to the power curve it got when it was tuned?

If you're referring to when it got tuned for your cam gears then no. You haven't listed any electronics so resetting won't have anything bad except you have to put your radio stations back in and adjust your time :D

When I reset my ECU I seriously got more mileage. I had on average 300-350 and then after I got a constant 400 out of the tank. I know a lot of people say resetting the ECU is BS... and it could very well be that but it has worked for me.

Also don't bother with the SAFC.... I had one... and before even tuning it I got a powerFC.

Yeah theres no electronics involved. Although there is an Apexi Multi checker which only monitors the engine, but thats it. A Bleed valve for boost, cam gears and then the bolt-ons I listed.

I actually got 550k's to a tank!!! I drove home from Melb to Mildura on a full tank. Although I never revved it over 3000rpm and only gave it a quick flex once.

400hp, you have an R33 GTR right?

And the way to reset the ECU is just by unhooking the battery and letting the power drain right? I might try that and lower the boost just a bit.

550km's would have been highway driving right?... I dunno where Mildura is....

I can easily get more than 400km if its hwy driving but I'm talking about city and regular driving in Sydney. And yep R33 GTR....

Yes thats the way to drain the ECU. I don't think it takes all nite. Unplug, stomp on the brakes (its what ppl say.. I dunno why)... all internal lights won't work or anything else for that matter. Leave it for 10 mins and it should be reset. I THINK!

400hp, yep all highway driving. 550k's on a full tank which i was surprised with. Considering its 240rwkw.

Meggala, yeah I will lower the boost for every day driving, but turn it up for the occasional V8 hunt.

So do you guys think that if I reset the ECU and turn the boost down a notch (to around 1.05 - 1.1bar) Ill get less overfueling, and then less black crap on the rear bumper?

Also, another quick question. Im sure my clutch is stock, but not 100% sure. It feels a bit heavy, and feels like it has lots of travel in it. ie, the clutch engages when its almost right up to its normal position....... or does that mean its almost worn out??

      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.
