why are you running 4 degrees at idle?

so, just for testing.... put the idle advance at 12 degrees and zero out the vacuum


advance for now..





ignition timing:



idle rpm 950

total rpm @ 2100

total advance @ 34

vacuum advance @ zero



lets see if the motor likes this





been working with a customer with the same combo





Engine 408 Chrysler (stroked 360)

Cam 507 lift 237 duration intake

502 lift 241 duration exhaust

Set to Performance cam

A/F Targets:

Idle 13.5

Cruise 14.0

WOT 12.8



Idle RPM 800

Total 2500

Idle advance 16.0

Total advance 32

Vacuum advance 8

Pimp squirt 25%

Power valve enrich 20%

Question, are the idle timing and total advance equal all in timing? Thought I saw somewhere that the idle and total timing equal the advance. In my case based on your recommendation 12* at idle and 34* total advance would put me at 46*? Or is idle not included in total advance?

Total timing is initial timing + the difference to get to the 32*. The system will not allow it to be over the setting you entered. Since the tech said try 12* initial the system will add a max of 20* timing. Vac advance is on top of that so they said to put 0* so you should see 32* max. I believe I read this on their FAQ plus I talked to a tech one time about it.

OK, that makes sense, thanks. Out of curiosity, what changes in the system when you select performance camshaft versus mild camshaft?

I left tom's on mild. Seem to do the trick.

Made suggested changes, car ran good on throttle, but did have a lot of detonation on top end. Still fighting the surging and eradic timing at idle. When stopped timing would go to 9.5* and even drop to 6*, not even close to the 12* I put in to the system. Think I am done, just too frustrating, ordered my FiTech EFI today, heard a lot of good things about the system and not so many good things about the Atomic.
