My 30 year old 7AL ignition finally died so I bought a Digital box. Any suggestions for bracket racing and Super Comp on these boxes?

Did you purchase Digital 7 or Grid 7730/ 7720?

Digital 7.

What model Digital 7 ?

7531

You are aware that MSD 7531 ignitions are restricted to Pro Mod class only. In NHRA, General Regulations, 8:3 Ignition, "The use of any programmable multi-point rev limiter and/or a
rate-of-acceleration rpm limiter, either by themselves (e.g., MSD 7561, MSD 7761) or integrated into the ignition system (e.g., MSD 7531), is prohibited in NHRA competition".

I typed the wrong number, it is a 7530.

I never really paid attention to the ignition boxes before because old reliable 7AL2 never seemed to have issues. I was basically given this ignition box so I am trying to figure out if there are any settings I should be concerned about.

It fired right up after installing and the only thing I've set are the rev limiters.

Digital 7 are excellent ignition boxes although obsolete now. Easily programmed with MSD Graphview that runs on any windows platform. The 7530T was popular, has 3 step, rpm, time outputs, start retard and programmable retards. If your ignition coil is as old as the failed 7al replaced, you might consider replacing it as well. The 7530T outputs 190mj.
