Where to set timing with 9psi powerdyne

Jeff Chambers · 01-12-2006, 08:08 AM

You don't say what PCM you have, which would tell me what kind of total advance is being commanded. The 9psi PD kits rarely make 9psi, usually more around 5 or 6 so at that point I'd be looking to retard the timing 3 or 4 degrees under boost; total timing probably around 27 to 29-degrees. This of course depends on what your compression ratio is in the motor. The car's going to run off-kilter until you get a tune on it. I'd find a dyno tuning shop in your area a make an appointment for a custom tuning session.

thanks for the reply, i'm running a stock A9L computer, no boost controller and 9.3-1 compression. i haven't beat on the car yet, shifted 2nd gear at 5300 and saw the boost gauge at 6psi, not sure how much more i can get out of it, kind of afraid to try with out a good tune. using msd dizzy, coil, and 6AL, definitely have enough for a good spark and more than enough fuel. so with all listed i should be able to set the base timing at 10* until car is dyno tuned??
