octane

riddlee josh · December 5th, 2008, 11:18 AM

how come my tuner only alows me to select 87 91 and premium octane for my tune. it won't let me select 93 or 100.
is there a reason why?
i have an xcal 3 it was unlocked when i got it. i bought it used from here.

i dont know but 87 91 AND premium sounds like premium is 93 IMO

riddlee josh · December 5th, 2008, 11:26 AM

well i was at bp and they had 87 93 and premium to select from. i was going to try some 91 octane but the bp did have it all they had was 93 so i went ahead a got the 87.

rwboring · December 5th, 2008, 11:27 AM

that doesnt make any sense? why not just get 93 then?

riddlee josh · December 5th, 2008, 11:29 AM

because my on my tuner i only can select 87 91 and premium. so i didn't want to get an octane that i couldn't match with my tune.

rwboring · December 5th, 2008, 11:33 AM

you can go better... but you dont ever want to just put a 91 or 93 tune in and go straight from 87 to 91 or 93... BECAUSE even if that needle is on empty you still have a few gallons left... you need to keep the tune down and run a tank through and stop changing what you run all the time....

riddlee josh · December 5th, 2008, 11:37 AM

i have my car tuner for 87 as of now but i was going to try 91 just to see if i could tell a dif. but when i went to go get 91 bp only had 93. so i am running the correct gas for my tune but i was just wondering why i can't select 93 octane on my tuner

rwboring · December 5th, 2008, 01:16 PM

like i said before if it has prem on the tuner that is probably 93... sometimes BP and sonoco call prem 94... but dont put the tune in till you run a tank through... just go somewhere else and get gas

gooberhead320 · December 5th, 2008, 02:17 PM

premium is 93. its what i was running in my car.

Lt_Crazy · December 5th, 2008, 02:19 PM

^^^ wow u only have 2 tunes.....my Xcal 3 came with an 87, 91 and 94 tune...im currntly running the 91...

MustanG_guy17 · December 5th, 2008, 02:27 PM

Fill up with 93... run the tank to empty.. Fill up with 93 again. Then Tune your car for 93-87 octane, you can run a 91 octane tune and fill up with 93.. Just never go lower then the octane your tuned for. You can always go higher.

me?

GreenFaleen · December 5th, 2008, 03:52 PM

93 is premium, on your tuner, and 100 cant be selected cause you dont have the tune

MWWarlord · December 5th, 2008, 05:54 PM

+1 you can tune to any octane, but you'll need a custom tune to do it. click on the link in my sig and Joe can help you out. Also at MOST gas stations 93 IS premium. I have my car tuned to run 93. However, I was actually running premium for a few months before I got the tune, so I was sure that all the fuel in my system was 93 oct. BTW, if I were you I wouldn't even consider going above 93 with your current setup. Once you have done a bit more you can consider going higher, but then you'd have to kiss pump gas goodbye.

riddlee josh · December 5th, 2008, 10:50 PM

can i advance my timing slightly with higher octane gas? i thought i had read something about being able to advance the timing slightly with a higher octane

blackmustang98_ · December 7th, 2008, 02:01 AM

i have the same question

SleeperStang88 · December 7th, 2008, 12:02 PM

i think that you can , but you dont want to raise em any higher than +1 or +2

riddlee josh · December 7th, 2008, 12:42 PM

how come no higher than that?

SleeperStang88 · December 7th, 2008, 09:57 PM

because your car is not built for it, you would need a motor that can handle it...........this is wat im told cuz i had the same question
i raised my buddies by +1 all across the rpms and +2 globally oh and only raise em if you keep your octane higher keep it at 91 or 93 trust me it makes the difference...the timing that is....itll feel a good amount more powerfull

riddlee josh · December 8th, 2008, 11:17 AM

yea i have mine moved up slightly with an 87 tune and it made a big dif. that is why i am kinda excited that gas is cheap and i can use a higher octane
