Default Timing Settings?

What timing advancement is everyone running? With the small mods I have listed in my sig, what do you think would be the optimum setting for my timing, performance wise? :D

ZERO; NADA; NONE Not even one degree.

Makes starting a little labored, but no ping now. Just ordered a MSD dial back timing controller so I can adjust timing from the dash.

Chip has too much timing and needs to be modded some more. Any volunteers?

Jake

Dude, no offense but WTF are you talking about. I think my timing is set at 10btdc now and I was wanting to know what others have found to be an optimum setting through trial and error. Thanks. :cheers:

My car was set at -4 when I got it. :confused:

I have since tried 6, 8, 9 with luck. I gained about 1 mph bumping it from 6 to 9.

I think what Jake was saying was answering the question you asked first as to what timing everyone was running.
I run about 10 degrees right now but need to experiment when the car is back on the road after some body work.
Jake sent me the chip I have now and it idles fantastic and pulls real good but I may have toomuch timing for it.I didnt change the setting when I swapped chips.

Experimenting is the key.
Advancing the timing may make the car feel as it pulls harder but take a bit longer to start...which was the case with my motor before.
In stock trim,my car loved 8 degrees for some reason.
:)

I spent a whole night at the drag strip tuning for timing and got the best times @9.5* BTDC.

Here is the link to my post on that in October.

Good luck and :cheers:

When we got the yellow 90, it was set at -6. It felt like a dog, so I bumped it up to +8 and now it runs like a champ on 93 octane. I had the 90 with the 383 set at 10deg, but it was also fine tuned in the chip thanks to Shalin. Your best bet is to play with it a bit with some scan software and just watch for knock counts. More than likely you will able to set it 8-10 and leave it alone. But every car is different.

You asked how much timing I was running and I told you. Zero, none, NADA, not even one degree of initial advance.
