My tune..

[4g63tcrazy]

Ok, well right now I'm running 30psi on the 16g with E85, 19 peak timing and a 12.5 a/f with 0 knock. My car is tuned with a Keydiver chip and SAFC. What I have been thinking lately, (as I'm already getting bored with the power the car has,) is upping the timing. I was thinking somewhere in the 22-24 peak range. But would that be too much? Too much cylinder pressure? I see most people running low 20's in the timing range that are running about the same setup. So what do you tuning guru's think?

Damn I need dsmlink!!!

Do it and see if it knocks :)

IMHO if it runs solid as-is leave it. I'm sure others can add in but shane told me not to push timing too hard on E85, as at some point you'll get diminishing gains.

Do you have aftermarket cams yet? Might do those instead of pushing your current setup. Remember not to be too greedy either. 16g is the imho the perfect turbo but way up top it leaves a little to be desired after a while. I say rock it as-is, or if you really want to know if more timing will really help, get it on a dyno :)

he has 272s if i remember right

People I have seen do that dont gain much past 18. Why so lean? Shouldnt you be in mid 11's?

[4g63tcrazy]

Yeah I have 272's. And my car likes it that lean for some reason. I trapped quite a bit higher the more I leaned it out. When I went leaner then 12.5 I wasn't trapping any higher so I left it there. I think I am gonna leave the timing. I talked to the guy who made the chip and I should be at 22 peak timing at 7k. I'll have to check my logger again but I'm pretty sure I was only at 19.

I'd say you could scrounge some more out of it with the almighty Link.

[4g63tcrazy]

I know for a fact I could get more out of the car if I had link. But until I can afford it, I'll be leaving the car as it is for now. I was just getting a little greedy I guess. Now I just wanna throw it on the dyno!

[munchgsx]

How much did the 18's mess with ya?

[4g63tcrazy]

Not sure what you mean exactly?
