Octane 95 For Stock Reset Ecu Rb25det Ok?

[markkin]

Hi.

I plan to import a Stock Nissan Skyline R33 RB25DET. Octane 98 is not available in my area. Would it be ok to use Octane 95 after I reset the stock ECU? Is the stock ECU hard map to using only Octane 100? Or, since I can not get Octane 98, I should import a Nissan Skyline R33 RB25DE instead of the turbo? I do not plan to race or modify the car. Also, what is the difference between ping and knocking? On my old car, my knock sensor was not working properly, so the dealer diagnosis it because the check engine light was on, so I had it replaced.

Knocking and pining are the same thing, differently worded. I beleive tuning the car would allow it to run on lower octane fuel, but you'd want to be even more sure that the air temps are cool especially on hotter days.

If you are going to mod, and run more boost, the summer air could cause some pinging if you don't run an appropriate intercooler.

That's my input, but i'm sure that more veteran-style users will give you better info. =-]

You could always run octane booster but that could get a tad expensive puting a bottle in every time u fill up.. lol

95 should be ok aslong as u run stock boost and get the car tuned correctly.. because fuel quality always differs..

How do you tune the car to run on low octane - by reseting the ecu and letting the ecu learn? It is always hot here - 80-90 F all year around.

premium unleaded (95 octane) is fine for a stock car. I've run 95 octane in my R33 GTST, stock boost with cat back exhaust.

I run 95ron full time as its the highest available here. I'd say fuel up with 95, reset the ecu & u should be fine. Stock ecu is not tunable... but, its clever enough to retard the timing if it detects detonation.

don't be ignorant people...

your options are:

1) don't get a car if you can't maintain it

2) if you MUST have it, then either get the timing retarded or the ECU re-written to accomodate the different fuel

i ask you this question... would you put deasil in, if it were the only fuel available in your area?

I ran mine on 95 for a while though you should wind back the Crank angle sensor to retard timing a little or get a powerfc and tune it to suit.

i run 95 in my 34 fine. i couldn't tell any noticable performace diference between 95 and 98 anyway but thats me

Hehe he says he's not going to mod :lol:

mate, its not for performance... its for the longevity of your engine...
