MSD programmable digital 6AL-2

Hey everybody--

I'm looking in to getting one of these programmable boxes from MSD. Has anybody played with one of these? From what I gather, you lock the distributor out and all of the advance curve is controlled by the box itself. This way, via PC you can hook up to the ignition box and ramp the timing in however you would like.

--I like the idea of being able to customize the advance curve because my unit gets a good bit of street use as well as some time at the track.

---Only thing that crossed my mind was--- If you are controlling the advance solely with the ignition box, and the distributor is locked out, Do you guys forsee any rotor phasing issues?

Any thoughts about this box or the rotor phasing deal would be greatly appreciated!

MSD's instructions on rotor phasing is right-on.
Slightly on one side of the post for NO advance and slightly on the other side of the distributor post for full advance.

I can tell you that the IGNITION part is just fine. I haven't gotten to play with the "programable" part yet.

MSD has great user forums that have tons of info.
Their tech folks answer posts daily.
It links from the MSD main web site..under support...I think.
The programmable products are very useful.

I have one on my BBF. You lock the distributor and install it at the highest amount of timing you want. The box adjusts the amount of retard. For example 36 degrees initial. You tell the box how much to remove at lower RPMs, say 20 degrees from zero to 1000 RPM to get 16 degrees when starting, 5 degrees retard at 2000 RPM for 31 drgrees, then ramping up to 36 degrees, no retard at 3000 RPM .

You can adjust the curve at any point, it does not need to be linear.

I experimented with using a map sensor to get some vacuum advance too.
