Ok, I'm working on ignition timing for EMS, and was thinking that
it is definitely ok to run stock ignition timing (load vs. RPM) while
load is non-positive.

then I'll interpolate values for positive boost at a rate of 1 degree of retard
for each lb of boost.

This seem right?

 

Yes, you will be fine for starters that way. Probably 3/4ths of a degree is plenty conservative.

Be sure to look at you ADV COMP window in engine parameters and make sure your timing agrees with the timing gun. It will save you a lot of headaches.

1 deg/lb may be too much. Try 0.8 or 0.75. I had horrible high rpm response/stutter with anything more than 0.8 deg/lb.

OK?

Read this post and d/l my ignition map at then end (not using it yet, but
I think I might be totally crazy)
