Need timing map for Accel Gen 7 w/ supercharged 350

I'm looking for a street conservative timing map to use with my Accel Gen 7 setup. I'm not looking to squeeze maximum HP out of this car, just a conservative base timing map to avoid detonation on pump gas. I'm running 8lbs of boost with 9:1 compression. You could email me your cal file to dave2brecht@yahoo.com as well

I have a wideband conroller and am running about 12:1 at full throttle/boost. I could probably also fatten this up slightly to 11.5:1?

Just throw in something like 32-34 deg at wot, 100 kpa map before boost ever comes in. Set it to come in around peak torque rpm maybe just before.

Idle depending on cam, run around 20-28 deg or so. Ramp up to 35-38 cruise over 2000 rpm and low maps under 80 kpa.

Boost tables take 1 deg out for each psi boost, so 8 psi you should be atleast 26 deg if 34 at wot 100 kpa. Or go alittle more conservative, 1.1-1.3 deg per psi.

11.5-12.0 air fuel should be ok. Aluminum heads for sure. Iron may want less timing and richer to keep cool but you will have to experiment
