Hey fellas, ive got an r32 gtst running a wolf 3d v4. My major problem is that its running incredibly rich and causes my whole rear end to be covered in a layer of black dust (lucky my car is black or else it'd look shocking :devil: ) Also, i only manage to get 300km's out of a full tank.

What would i need to do to fix this problem?

Thanks, Miguel

How much did you pay for the tuning? Possibly they have only charged and performed mapping for WOT so it doesnt destroy itself.

Getting the cruising economy acceptable will require them take the car out on road (or dyno) and tune for light loads. Which will take more tuning hours and hence more money.

A lot of people are quick to blame the ecu and/or tuner for poor results when in some instances its simply the end user has not paid for it to be done.

Those on here that tune there own cars will attest that there is a lot of hours needed to get a acceptable result.

To answer your question, it has not been tuned correctly if at all for your cruise situations.

also, i no this may sound stupid, but how is your cat? i had the same problem, with piles of black crud and it turned out my cat had been punched out...

Its still running rich though, having a cat will just lessen the black soot that comes out and make it less obvious.

    • Drain it. I got official Matic D but you can get whatever is listed as Matic D compatible.
    • Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻   
    • Nice car! I’m glad folks in the US have gotten past the FnF and are buying real cool cars like the 260RS I was with a bunch of mates in Portland about a year ago and spotted a green Stagea (just a regular 2.5T AWD) parked about 2 blocks away and they were like “a what?” So I made a bet with them for a round of beers and said “ok one of you run down there and tell me if the steering wheel is on the correct side” 5 mins later the American comes trudging back up the hill and goes “he’s right guys. Ok what beer do you want?”
    • Should replace OR drop the tank, give it's good clean. Might be worth replacing that entire fuel level/pump/cradle thing with this: https://frenchysperformancegarage.com/products/fpg-s13-180sx-r32gtst-single-pump-hanger-kit-billet-hat-6-v3-fpg-089?gQT=2
