Just Bought A R32 Gt-R :) Need Advice

[Moodles2]

if i ran the mines ecu with octane booster would that help in the mean time before i get an new ecu

Some octane boosters generally do bugger all, check this link for the ones to avoid: http://www.elanfactory.com.au/pdf/technical_information/Octane%20booster.pdf

The best way to help in the mean time, is not to drive it hard. It's that easy.

hahaahahha wish i saw that, car became totally unusable 5 mins after putting the octane booster in, im getting it towed to advan perfomance center today, getting my self a LINK storm :) get rid of the mines ecu

oh shit. random! Never known the octane boosters to do that. UNless it finished off a plug on the way out or something...

Also just to be warned, if you have driven that car hard and felt the way it responds under full throttle and builds power- you will probably find that it wont feel as good as that after having a tune done. Mines ecu's are so aggressive that they make the car feel awesome. The tune you get will be alot safer on your motor and therefore the car is likely to not feel as responsive or build boost/power as quickly.

The tuner may however feel that you can raise your boost and outright power so you may be lucky in that regard and indeed find more top end power to be had as a result.

Good luck and let us know how you go mate.

Good stuff, you won't be disappointed

To backtrack a few posts....my experience with United 100 was that it felt approximately the same as running BP98, but used noticably more juice and therefore cost a bit more to run. Therefore I decided no benefit.

An important point about octane and ignition timing and power is that an engine will make more power the closer to the detonation threshold it is run. If you increase the fuel octane and therefore take the operating point further away from the detonation threshold, you can reasonably expect to make slightly less power. It's the same old thing over again. Safety vs power. More of one equals less of the other.

Yeah I was so shocked when I drove it, only on stock boost it felt soo responsive and pulled so hard, I guess I'll hAve to compensate by turning the boost up

Very interesting. I noticed no difference in economy.

A mate in an EVO tells me he gets another 40kms to a tank (it's his daily and takes the same route to work 5 days a week).

And you say it's worse.

Could perhaps be tune related on all 3 accounts?

I could also dump in a few more degrees of timing using 100 if i really wanted. Although seat of the pants i couldn't really see much different from +2

It could easily come down to how good the tune/management is and how the car is driven too. My regular drive is fairly stop start in traffic, so my consumption is dominated by that aspect of the drive. If someone else has more of a freeway drive, they may get a completely different result. More closed loop running vs less, more opportunity for the ECU to wind in a bit more timing whilst cruising (if the ECU is clever enough, which the Nissan ones aren't really, but I think the EVO ones are).

That experience was with my RB20 though. Haven't tried it with the Neo yet.

any United stations selling 100RON near sydney CBD ?

will the 10% ethanol have any affect on the car with a 98 octane tune?

I too use United 100RON over Bp98,

I noticed the car drives better across the whole rev range, there has been no difference in economy and on average the price is a bit cheaper than bp98

[SiR_RB]

The 10% ethanol in it won't affect anything long term?

Might give this a go next time in near roselle

[jjman]

Any word on how your ecu install and tuning went?

All good? got some nice numbers and seat of your pants feedback for us?
