Help with intake/tuner
Hey guys,
I installed my intake and tuner last night and programmed (or at least I think I programmed) my 93octane tune that was on my predator tuner. When I drove it to the gas station all was well, but then after I put gas in it (3/4 93 1/4 89 which was left in my tank) I threw a code. I think it was b/c the o2 sensor was loose (both screw heads broke off!) So, I fixed the code but didn't reallyfeel a difference w/ the 93 octane/tuner/intake installed. Could it just be that I was mad at the problems or do we really not feel a difference?
Thanks guys, I wanna feel as if my money was well spent.

RE: Help with intake/tuner
You should feel a big difference going from the stock tune to ANY custom tune, even going to the custom 87 tune. I suggest reloading.

RE: Help with intake/tuner
What do you mean you "fixed the code"? Do you mean you just cleared it, or did you find the problem and fix it?
I would say that because you had 1/4 89 Octane left in the tank, your 93 tune caused the CEL.
edit: This is also why you didn't feel a significant difference in performance. Your car probably pulled timing because of the code/lower octane.

Run through your current tank on the 87 octane tune that came with the Predator. When you are able to completely fill with 93, switch back to that program.

RE: Help with intake/tuner
ok well, unfortunately, i didnt know that i should have ran the tank dry....so, what can i do now?i have a full tank now and have been driving it for a bit..i THINK i feel a difference in throttle response before 3k..before it bogged..but now i think its better...should i load a different tune? leave it for now? get more 93octane???? thanks for ur help guys..i appreciate it
(oh and when it comes to the CEL...i looked at the o2 sensor and i was pretty much hanging out of the socket..so i put it back in, reinforced it with a screw and some loctite over the screw...and the code was cleared w/ the predator....no more light)

RE: Help with intake/tuner
I'm assuming you are talking about the MAF sensor? Even if that did fix the problem, here's what I would do:
Load your 89 octante or lower tune. Drive until empty and fill up with 93 octane gas. Run that tank through with the 89 or lower tune again. Fill up with 93 octane gas and then load the 93 tune.
edit: By the way, what intake do you have?

you know what, i think it is the MAF sensor!! sorry, and im running the C&L intake w/ the predator tuner..so i should reload the tuner later on huh? go back to the 89 even with a 3/4 full tank?

There is a table in the PCM called the "Knock Advance Limit". What it's job is, is to advance timing by the amount the table shows, (based on RPM and calculated engine load) when there is no knock present. In just about every tune I have ever seen from an aftermarket tuner, when they add timing, about 60 to 75% of the timing they add is in the base table, and the balance is here. Why would they do that, you ask? Suppose you head to a gas station, and the station is less than reputable, but your stuck and have to get gas, but their 93 is really more like 90... Or, perhaps Cletus the gas attendant gets confused and accidentally pumps in a gallon or two of 89 or 87 before you catch it... or on the pumps with one nozzle, the first half a gallon is the grade of gas that the LAST person to use it got....
I mean, come on guys...
/end rant
to the Op... If your O2 sensor was hanging out of the pipe, then 99% chance that that was it. The car was detecting a super lean condition because it was samploing mostly clean and and no exhaust and decided that something was wrong. Next time, if you could, post the code number it threw and that can help more.

Ok guys... I've read this crap enough to make me wanna pull the last few remaininghair I haveout. Our cars are not so stupid as to throw a code from a slightly lower octaine ratig than the timing would suggest we run... also, your not going to blow a motor because you have an 1/8th tank of 89 and filled with 93 and are running on a "93 octaine tune"... jesus. Why do you think we have adaptive spark tables, knock sensors and the like?
