2.8 like more timing?
Now that I found the how-to and the stock spec, I'm wondering if these 2.8s seem to like a different setting for initial spark advance? I read the FAQ sticky and the first half dozen posts of the more-power sticky, neither of them had the answer.

Re: 2.8 like more timing?
set base to 14* instead of 10* , its will make a lil bit of difference.
just keep an ear out for pinging when u do it , when i first turboed my stock 2.8 i ran the stock timing curve with an addition 6* of advance and it never pinged even under boost on 91

Re: 2.8 like more timing?
I'm not sure it ended up anywhere near 14*, but it is moved. I have hard starting, but when I floor it from a stop it spins the right rear! This is an improvement to driveability, so next will be checking what it does to gas mileage.

Re: 2.8 like more timing?
sounds like ur way past 14* as 14* base shouldnt cause hot start issues

Re: 2.8 like more timing?
After driving home I think I'll back it off slightly. Only this time not loosen the hold down clamp so loose.

Re: 2.8 like more timing?
Yea that dizzy clamp down is a pita. This is one thing I like about ford..the dizzy is in front so it can be a easier to adjust.

Re: 2.8 like more timing?
Finally, success!
My import timing light isn't good, but I'm sure I'm above 12*, and I have instant fire-up.
I guess my rough idle and hesitation is something else. Going to try cleaning the idle air control thing next, may have carbon deposits or some such.

Rough idle? Have you checked for vacuum leaks?

Wow! So many relevant results! Froddoyo's thread looked close, read it, it looks helpful. I'll try that tomorrow.
