hey read!!, well... Options

on my celica i have a few mods and my cuisn tweaked with the timming a little bit and if u know what im talking bout the timming was set at 16 and it used to be at 5 and i noticed it gave it a lil more power and it kinda sounds a lil like its "caming". but it drives better and i have not noticed any problems at all..
what do u guys think about this i would like ur info......

you have to set BASE timing, jumping those connectors sets the timing back to BASE with no advance or retard. he's not measuring base or setting base. he's just messing with timing at idle. without the pins jumped idle timing will advance and retard back and forth with load and rpm slightly. you just cannot set base timing with out putting the pcm into diagnostic mode!

so ur suggestions are to jump the terminals, but i still kinda want mine on 25 degress is this to high btw?, so jump the terminals then what cause i want mine in that setting just let it iddle or something?

just jump the terminals. if the car is running you'll hear the sound change when the terminals are jumped. then, while it's idling, set the timing. I wouldn't set it to 25 right off the bat though. because if you set it to 25 while the car wasn't in diagnositcs mode you could've been really setting it to 15 or 30 or something else without knowing it. so try 20, drive it for a day or two, if there is no pinging or rough idle or anything, then move it up again. if there is pinging or rough idle you better move it back down again though.

Anyone tried running on ethanol blend + advancing the timing? Here in Australia we've got E10, which is cheaper than regular and has a higher octane rating. From what I've read Shell is selling on with 100 octane.

From what I understand the performance is pretty much unaffected by switching to E10, but the potential for advancing the timing is interesting.

we've had that blend here in the midwest united states for years, theres little to no performance increase from the ethanol alone since here when its blended the octane of the ethanol is taken into account. slightly less fuel mileage, a little more corrosive, same price (or a little more when its been a bad corn crop).

too much timing, even if you dont have ping, wont make more power. you can get gains advancing to a point, but beyond that you'll make no more power or loose power. best bet is to do a little advance at a time and stop when you get ping or stop feeling gains. 15 feels good to me, 20 had no more pull than 15. but the GT is a different motor, but start off slow. higher octane with higher compression, more timing advance, and maybe a better pair of cams, then you could have a motor which would be able to use all 100 octane and not just be pissing away your money.
