Is it ok to use this fuel in my 07 gp?
07-24-2011
yes
07-24-2011
Most fuels have 10% ethanol in them anymore.
07-24-2011
I know regular and mid grade fuels contain ethanol but shell and husky states their 91 octane contains no ethanol, atleast in my area... Just want to try 94 octane and see if it helps with my KR.
07-24-2011
whats your mods??
because that may be casuing your issue, you may not have enough mods for what what your running.
07-24-2011
Wizaired cai, TB spacer, headers, 3" dp w/ magnaflow cat, slp 2.5" catback, 1.8 RRs, NGK TR66ix gapped at .060...
07-24-2011
throw the TB spacer in the garbage, thats a coolant leak waiting to happen, its a joke of a mod.
Any pulley drop???
Is the car tuned?
07-24-2011
Stock pulley, cant tune an 07 pcm yet... lookin into gettin a tuned 05 gtp pcm but im not sure if it will work..
07-24-2011
how much KR are you seeeing??? You got an aeroforce gauge.
07-24-2011
Ya I got aeroforce gauges.. Iv seen up to 4* when i get into it good... Iv seen up to 7* when I accelerate in 3rd and 4th from low rpm...
07-24-2011
Any ideas fivefinger? I don't understand why I'm still gettin kr.. All the mods iv done were to try and get rid of it, my latest bein the RRs which did help a little bit and I'm almost positive it's not false kr because when the engine is still warming up I don't get any kr...soo maybe if I can get a tuned PCM that'll solve my problem...?!?
07-24-2011
the knock sensor's dont turn on till 160-170* so thats why you wont see any then.
I say it needs a tune to help it alot.
07-24-2011
Well that's good to know.. I'm going to have to fix my clearance issue with my headers and fan motor...maybe I am gettin false kr...
07-24-2011
its possible some could be false. the o2 sensor might be hitting the tunnel or the DP hitting the sway bar.
but a tune will help with timing and adding fuel when needed to handle the knock.
07-24-2011
The o2 clearance looks fine but the DP to sway bar clearance is pretty tight and my front header has made contact with the fan motor so il have to fix that somehow. On my next fill up I'm going to try the 94 octane fuel see if I notice any drop in kr, I currently use 91 octane. Do you think that octane increase would make a big difference?
07-24-2011
It could!
07-25-2011
Get some poly dog mounts, that's how I stopped my headers from hitting my fan. That's gotta be false KR
07-25-2011
Always err on the side of caution with KR. Because the bad side of KR is holes in pistions etc.
Fix the known rubbing points and see if that clears it up.

99/100 times its not false.Originally Posted by footballplaya3k

you can use on 05 pcm to tune, on the 07-08 it makes your fuel gauge work in reverse but other than that you will be good to go on the tune.
