1. 97 RON doesnt cause any problems, Ive been running it for years on track, drifting, all sorts. 2. I think you misunderstood my post. The ECU will retard the ignition timing if it senses knock occurring (the sign of lower octane fuel) but I dont believe it advances the timing if it senses 101 RON, for instance, and if its not changing the timing then its unlikely theres any benefit being gained rfom running 100+ RON From Jez @ Horsham... "The ECU will only react to knock up to about 5.2k - if it knocks a lot in that rev and load area the ECU will switch over to the low octane maps which have around 2-3 degs less ignition advance. So you still get less advance over 5.2k if the engine is in high knock mode. The amount of knock required to get the ECU to switch to high knock mode is still quite significant - so damage could be done before the engine switches maps. Also, pulling 2-3 degs out of the ignition map isn't really that much if you're going from 99 to 95 RON fuel. So, I agree - run the car on 98/99 RON and if you have to run 95 then drive gently and refill with higher octane fuel asap." hope that helps.

No I didn't. It was extremely tight on the engine cover.

Uprev will ensure your car runs properly on 99 Ron. But then you must stick to it. Ideally.

Ecu will not re program itself. The 350z is only designed to run on 98+ Ron. Yes it's only one Ron different but it's not the right stuff. We know that 95 is definitely wrong and what can happen but I'd have thought even 97 would create issues, albeit at a slower rate.

Fitted fine on Arran's DE with spacer. However with mine, it required a bit more work. It will be fine if you do not have polished tubes like my Injen does. So standard intakes and silicon hosed intakes are fine. Supercharged and Stillen/Injen polished intake tubes, it will fit, but it's really tight so you may end up damaging your polished bits.

Science amazes me every day...

Did you read the first page?

12000 miles a year will cost you £110 extra in v power vs normal shell petrol. Are people really that cheap? Thats on the assumption of 20mpg.

Iv'e got one of those t-shirts from 3 years back but they were NOT gentle with me Sent from the golf club... Oh!!!! That's why you walk funny!

! I think you got conned, and obviously have too much money! To the op, and you should be able to find one for that amount.

Make the plates yourself... I did this.

I have purple haze pro and r222 beats it hands down for that concourse finish. The haze lasts longer to repel water though.

Payment sent.

Wrong! and we are not telling so you can waste your time guessing all you like But any more on this thread will be deleted (never used that smilie before ) Fair play.

Happy Birthday dude!

Do you want me to sort you out for this month? You can pay me back next month.

So Adrian, what's the warning point for???

You mean like this...

You should check out the Pioneer appradios. Look at my build thread. Much easier and simpler.
