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??

    • You're not the first person that's said that about this car lol. A Touring wagon GT in Spark yellow mica would be the dog's danglies 😆 I will keep an eye out for a future purchase for sure. The seats are almost like the OEM Recaros... electric adjustment for fore/aft and tilt movements except reclining.   
    • Yes!! I love these! It's a shame its not the wagon though!   Thank everything that's holy that it doesn't have the interior of the Aussie delivered ones. Those seats are so much nicer.  
    • I'm both sorry and thankful that you do that. 
    • 2001 BE5D Subaru Legacy B4 RSK (3rd gen) EJ208 (pink injector) Twin Turbo 280PS 5-speed manual Full time 4WD "RSK" grade which means all of the above LQC option which means stock rear spoiler  I got it primarily to export to someone outside Japan who was interested. These BE5 Legacy B4 RSKs are going through a bit of a resurgence right know in Japan as they are one of the few cars from the "turbo, manual, RWD/4WD, 280hp gentleman's agreement era" cars that don't require stupid money to purchase. Which for some people might be a good opportunity to get as a base for restoration. If I can't find anyone to purchase it I will certainly be doing that myself over the long term. Why? Because it's properly fast in stock form, handles well enough for a GT sedan, there's still enough aftermarket and (if you can wait a while) genuine part support to make it a restoration candidate (<-- that will only get worse over time so it's a case of do it now or choose get a BL5 4th Gen). Mechanically it's fine, has only 89,200kms on the odometer. The problem with this car is that the body and exterior trims are weathered from at least the last 10 years being parked outdoors. I'm the 3rd owner, the first owner was the one that had it for 14 years and barely drove it, had a low-speed front impact (which didn't damage anything behind the radiator support) and got it fixed and sold it. The 2nd owner put most of the kms on it and parked it outside for the last 10 years, hence the door rubbers have seen better days but if you overlook those cosmetic details, it presents pretty nicely. There is some minor rust on the LH rear wheel arch which I'll have looked at too at some stage.  Also as you'd expect from a car this age, the clear top coat is gone, leaving a satin finish on the roof.  Mechanically it's fine (as you would expect from a car with less than 100K kms) but the steering does feel slightly vague around the centre position at higher speeds. So first on the list is to get the steering rack bushes looked at. There's also the Lock button on the remote which doesn't work, but the Open button does.... it means that the anti-theft system thinks it's always open? It seems like if you open the car and don't start the engine within 3 mins or so the anti-theft kicks in again without any beeps or signals. So if you got to start it after that, it won't. You have to push the open button again. That's how I understand it anyway. Just a small irritation but not a big problem to sort out. There's only one mod, the Wangan SPL muffler. Just a tad louder than stock. It's a really good mod for those who don't want to wake the neighbours but still want to hear a more prominent unequal length header EJ20 sound. Anyway I hope to get all those things done eventually, that is unless someone wanted to import it to their country from Japan (where I live). I'm open for negotiations as I really would like a Skyline... but this will definitely suffice in the meantime 🙂 *Disclaimer: This is how I picked it up from the dealer, minus the stuff on the back seat. I haven't cleaned the engine bay or done a thorough exterior clean, aside from spray painting the wipers. 
    • Wow, even with the Audi logo centre caps. I love OEM wheel mismatches.
