I've run 2 tanks through the GTR since I discovered it..

I've noticed the following difference in the cars performance changing from optimax/bp ultimate:

- no more popping! the car does not pop at all anymore. previously it was running quite rich and popping about once per gear change

- the car is a lot smoother

- the engine is more quiet

- the car pulls a lot better

I did a search on here, and must admit the user comments about this product is pretty dissapointing so far. Particularly those who have not tried it putting in their stupid opinion.

Cheers.

Ok i have run a tank....

My check engine light flashed fairlly often recording a knock level of 70 or so under boost....

Same settings on regular 98 (oltimate or optimax) and i can only just get to 20 knock level....

So i will NOT be using it again....

Unless you tune on it dont use it.... Use the fuel that your car was tuned on.

Thats funny, i noticed instantly running quite high boost (20psi) with this new fuel, that my knock has come down quite alot. I will do some more testing but on high boost with 98 fuel, i used to see knock in the 90's, so far ive seen this drop to 60. Save me taking some timing out of her.

col: i would imagine you would have to get it tuned for the stuff.. thats what everybody has been saying..

then once you do you keep having to use it, so you are stuffed again.. for that reason don't think i'll be using it for a while. That's probably what everybody else is thinking too, so nobdody will adopt it and they'll give up?

We'll see I guess :D

Yeah im sticking to 98....

I stuffed up my pfc today playing with it to tune for 100 ron....

Ended up just reseting it and putting the standard ecu back in....

I just need to go to mercury to get it tuned properly....

I have lost so much power...

Now i have my injectors i can finally bolt up the new turbo... But now i have to re consider my plenium....

Anyways back to the point... Ill stick to 98 due to lack of supply of 100ron....

    • Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though
    • and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.  
    • Oh, you are right. But, in Australia E10 is based on 91RON fuel and ends up being 94RON. Hence it being the cheaper option for economy cars. The more performance oriented cars go for the 98RON fuel that has no ethanol mixed in. The only step up we have left then at some petrol stations is E85.
    • There is a warning that "this thread is super old" but they ignore that anyway...
    • With 10% Ethanol, we're talking 2-3% fuel consumption difference. The emissions reductions and octane boost in my opinion far outweigh this almost non existent loss.    My tanks sitting at 80%. Luckily that should go down fast as I'm on vacation again for the next two weeks.
