Hi all

Just picked up the car today and have a q..

The person i got the car said I should get the car tuned for 98 octane as it causes the timing to be a bit off and runs a little lean. Is the tune necessary and does this mean i need an aftermarket ECU? He suggested i use octane booster in the meantime?

Cheers

- Eric

edit: as you can see, i am a noob so plz no flaming ^^

Skylines do prefer higher octane fuel, but a tune/aftermarket ECU isn't needed unless you are modifying it. About all you should do is reset the ECU, which causes it to relearn the timing advance parameters. Do a search on how to reset the ECU, there are several ways of doing it.

I agree with Abo.. tho I would perfer to go with BP Ultimate, if possible.. :D Tho Ant is also correct you should reset the ECU to allow it to self learn/adjust it self to the different fuel qualities here. As to resetting the ECU I didnt find anything on the net to perform it, so I spend 100bucks n got the ECU data streamed (this is to see if the ECU already had any fault logged, at the time my HICAS light was coming on n off) and reset at the same time.

I found that resetting the ECU seems to make the car abit more responsive. Oh congrats on purchasing such a nice car. :D

I've had my car running on BP Ultimate for 6 months now. The previous owner had used optimax and octane boost once a month. While I haven't reset the ECU, the cars running fine. It goes in for a regular service next month and as part of the service they will be dyno tuning it for road use...

      I am yet to see anyone ever regret a quaife or helical. ...other than drifting/skidpan duties. I kind of want to upgrade my factory helical with a Quaife (but really it's not ultimately that different, and is a MASSIVE UNDERTAKING), that's how good the hype is about them, that I want to try them 'just to see'

      D2 and Ksport are essentially the same thing and basically just generic Taiwanese manufacture. Better than ChinaBay crap, but... not top shelf. Öhlins have got to be some of the best dampers around, so likely to be a good option. It's going to get to the point though where I suggest you buy from Oz. We have at least 2x excellent options here. If I were you though, I'd be talking to KW about doing something for the R33. There's bugger all difference between that and the 32. In GTR land, anyway.

      KW only offers a set for the R32 GTR. Popular options are D2 racing, Ksport or Öhlins. I have a D2 Racing coilover set, though I don't know for sure which one.

      Well, the good news is you have more than one very good option for new coilovers in and around your country. Worth the drive over to KW to talk about GTR stuff.

      Fair enough, I am in no way a tire expert so I'm not familiar with all the terms and conditions. I'll definitely note down the AD09 to potentially try in the future. Rain is not too big of a concern for now as I will probably only drive in the rain when I have to. And considering I still lack experience driving the GTR I'd more than likely take it easy too. I have coilovers in the car but as I barely got to drive so far I never bothered to even check if they are adjustable haha. The suspension is almost entirely old and worn as well so I suppose when I eventually fix that in the future that would make a huge difference.
