Hey guys,

I have searched for topics about this, but have been unsuccessful so far. It is s bit of a noob question, but I thought I would get different peoples opinions.

I have a r32 GTR due to arrive next week from Japan etc running the stock ecu. I am a little lost on the whole fuel thing , and was wondering what my optionsr for different fuels are....

I understand the difference in octane in japanese fuels and fuel here in aus, however is it as simple as;

1. Use 98 with octance booster, or

2. Upgrade ecu and tune for lower octane fuel,

I guess I am looking for peep's experience with different fuel and how they have solved this issue.

Nulon makes 2 grades of Octane Booster.

Once I detected pinging immediately after filling it with 98, I started using the stronger version of the above - trying to boost the octane up to perhaps 104 in the tank. I kept this up until replacing the Mine's ECU.

Result:- Whilst pinging reduced somewhat, but not completely, 8 tankfuls later when I switched to a PFC D-Jetro, the plugs were just about etched to death.

Moral:- I wouldn't use the octane booster for more than about 3 fill ups - in the interim, getting that new ECU if the existing one can't be remapped.

When the GTR was released in Australia the highest octane petrol you could buy was 95 octane. They ran happily on that. True story.

So you can actually run a stock GTR on 95 octane. Most people use 98 and they are perfectly fine with that too. Stock or modified. You dont need to mess about with octane booster.

Mines ECU's are notorious and you'll not find anyone recommending them. But you dont have one so it is not a concern.

Yeah nistune is what I have decided on. Any recommendations on workshops to have the mod done in melbourne? I have heard status tuning and chasers are worth looking at....

Status = Chequered = Recommended

Just bought an R32 in Japan.

So they are okay to run on 98? I have united 100 a couple of kms away but would be easier to run on 98.

Would prefer not to modify the tune, car is 100% stock.

Cheers

      Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

      Leak from Tokico BM50 Brake Master Cylinder

      The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/
