drive very conservatively until you can use 98. If you have E85 around, squeeze some of that into the tank and dilute the 95. Around 10-15 litres will help, octane booster will also work if you get one that actually works.

on a NA 95 octane should be fine. any misfires on 95 won't be from the octane rating. might be from the quality of fuel, but not the octane. you could also try backing the timing off a bit if you are worried.

japan's octane ratings are the same as ours, they just happen to have one that is even higher, but they still have 91 and 95 octane fuels over there from what i gather.

Geeze u guys do like if 95 is kerosene or some shit....

Where i'm from 95 premium is our best brew and we run all skylines on that with no probs...just keeping the boost down on hot days

i run e10 95 in the stagea and keep the boost to 5psi most the time and it runs fine

even on 7 psi its ok, down a bit of power compared to 98 but its fine

Yes, but the average altitude of Japan is about 1000m, whereas our average altitude is about 400m.

I believe the "knock" map on the standard ECU is designed for 95 octane.

Yes, but the average altitude of Japan is about 1000m, whereas our average altitude is about 400m.

What's the relevance of that on a MAFed engine?

i forgot to tell you guys that my spark plugs was the cause haha. running on 5 cylinders was fun.. NOT

95 is fine stuff but i still run 98 nowadays

Not trying to be rude, but a car down a cylinder sounds a lot worse than the odd backfire... How did you not notice?

    • A 1.5 way is a 2 way. It is just a 2 way with a less aggressive ramp on overrun.
    • The ABS and/or TCS being missing/broken will not cause the engine to misbehave. It just casues CEL to come on and annoy you. The CEL is useless if it is always on, so you have to do the things you have to do to get rid of it, so it can be useful. Being a Stag ECU, then yes, it will not expect TCS to be present. But it will expect ABS to be present and working. You will need to either make the ABS CU talk to the ECU (don't ask me what that will take on an NA R34), and make sure the hardware is working....or, you just need to blank it out in Nistune. Do not persist with the stock ECU. You will just have problems. Gte it Nistuned. Start from there. DO YOU HAVE A BOOST SENSOR? The ECU's boost sensor that it. It is connected to the loom at the rear of the coil cover. Usually rides on the firewall on an R34, but is usually bolted down to a bracket along with all the other crap at the back of the coil cover when a Neo is dropped into another car. If you do not have it, the ECU will shit the bed. So, do you have one?
    • So sadly the fuel pump etc was not it. The pump and filter is new and it is still cutting around 4000 rpm. A read something about ABS/TCS (engine is from stagea and ECU too so no TCS) and i dont know for 100% that my car has ABS. It has ABS "cube" in engine bay but i dont think it works(or at least from my braking experience). Can be something like that?  I will be driving the car next week to Nistune tuner to properly see what is wrong...  
    • the Tomei LSD fluid with lsd kit. frustrated that it was shaking the car to crap and affecting everything else negatively, I pulled the diff last night, and removed the lsd carrier, could not find anything wrong, however it seem to be 100 locked up acceleration, and deacceleration, wondering if they sent me a 2 way not a 1.5??  either way I installed the stock open carrier back in place. test drove everything smooth as butter again. no shake, shutter, random, what felt like clutch slip and grab or drive shaft play, etc. something differently wrong in side the lsd. I might bother taking it apart (if possible) to figure out what's going on inside this carrier, as bought too long ago to return.  only draw back is its back to a one wheel wonder.
