RPW Tuning Day NSW Saturday / Sunday 27/28th November

Well i use nothing but 98 octane fuel, always have, it is a bit more expensive however it's beneficial

[JaCe]

I'm assuming the 98 octane fuel requirement applies to all your tunes.

Lucky for me I'm already stuck in the pricey line at the servo

[lukeaday]

I have only put one tank of 98 in my car.
What are the side effects of this if I just use regular 95

[JaCe]

^ It depends on the car and the driver but I think it's been proven that higher octane does lead to better fuel economy, better performance, and offers engine cleaning benefits... but whether that's enough to justify the price difference is still up in the air.

[Bandit]

I think it is only the 98RON 'premium' fuels like BP Ultimate, Caltex Vortex98 and Shell's V Power that have the added detergents for engine cleaning. The fact it is 98RON alone doesn't mean it will clean the engine.

As far as I know, none of the 95RON available have detergent option.

[JaCe]

Fair enough. I'm struggling to think of any other servos which offer 98... Mobil? *shrugs*

Either way I'm a Caltex/VPower guy anyway. No BP's near me.

[Mitsiman]

running 95 ron fuel may induce slight detonation under hard driving conditions. Worst case is the ecu will pick up slight knock and retard timing and richen the fuel up. It would be okay for normal daily driving but stay with 98 if you plan on pushing it hard.

[liam92]

Its probably wise I continue using 98 all the time then

Back on topic, the only thing which I am worried about is just in case we need to go back to stock map, it'll cost quite a bit at Tunehouse ($100).

Which reminds me i need to get in touch with david to get the file off him.
Yeah sounds like going to cost more to go back to the standard tune,but the question is will we go back?? lol The only plans i have at this stage is maybe a full dyno and maybe a axle back exhaust.

I have noticed when using the CVT in manual mode,the car certainly picks up a bit quicker in 1st gear after the reflash,around 3000 rpm.

Leaving it in Auto mode,cant tell much differance.

[JaCe]

Even if we don't, I like to know that I'm not dependent on any single person should I wish or need to go back to stock tune. More for peace of mind than anything else. You never know one day you might need it.

Yes true i can understand that

[liam92]

Agreed, Ill email david and get a copy of my stock tune too
