timing and fp?

[94gtslow]

Ive had my timing at 10 and fuel pressure at 40 for some time now, ive never really tuned my engine. Just wondering what people with simular combos are running, i also have 30 pound injectors if that makes a difference.



also does anyone know how to adjust the idle. I just moved the screw up and down on the t-body, just wondering if there is a way that your are suppposed to do it, like so many turns down or up etc..

You can use this screw to manually hold open the throttle plate and adjust your idle RPMs, I recommend 850-950rpms. After you get it to idle around 900rpms, without the IAC connected, reset your TPS voltage to .990v or close to, with the key on engine off. Finally disconnect the battery for 10 minutes and plug the IAC back up.

This procedure totally cured my stalling problem when I started modifying my car. The problem is once you start modifying the engine the airflow is changed enough that the computer becomes somewhat confused and this doesn't allow the IAC to keep up. The result is the car dies. Since the throttle plate is NOW open at all times, the IAC does not control the idle when warm and therefore the car will not die.
