The Procomp PC6AL-2 is the most powerful cd ignition of its type available. It is a multi-spark, capacitive discharge, electronic ignition designed for high performance street, drag racing, oval track and marine applications.
The PC6AL-2 uses the latest state of the art digital technology, and when used with the Procomp high performance coil, produces a spark gap current three times greater than most similar systems and almost eight times the spark of the standard ignition. This CDI unit can be triggered by magnetic, hall effect, points and crank trigger pick ups. Includes a Soft Touch rev limiter, which does not require chips. Produces multiple sparks between 0 and 3000 rpm.

With Rev Limiter
- Our Flathead Ford electronic distributors 910-8351, 910-8353, 910-1000 will require this ignition control box.
Additional instructions: The 5 rotary dials on the end of the unit (3 to the left of led light - 2 to the right of led light) function as follows:
The dial to the far left of the group of 3 is the 1,000 rpm limiter dial. The center dial of the 3 is the 100 rpm limiter dial. The dial to the far right of the group of 3 is the # of engine cylinders. Therefore, if the the max rpm limit on a V8 cylinder engine is 7,200 rpm, the far left dial is set to 7, the center dial is set to 2, with the 3rd dial of the 3 group set to 8.
The other pair of dials to the right of the led light are the launch rpm limiter or the 'first' rpm limiter. The left dial is the 1,000 rpm with the right dial being the 100 rpm limiter. Therefore, if the launch rpm is needed at 3,500 rpm at full throttle, the left dial is set to 3 with the right dial set to 5.
Red magnetic pickup wire is (+) polarity on a distributor when commonly used with the violet/purple control box wire.
Black magnetic pickup wire is (-) polarity on a distributor when commonly used with the green control box wire.

For a hi performance Classic VW Beetle engine, what spark plugs will match the 6al the best?
ProComp distributor; 2015 6al; MSD wires, Speedmaster coil.
December 30, 2014
The MSD sparkplug listed as correct for your stock VW application is 5473740.
MSD recommends that you speak with their Tech staff for a “colder” sparkplug suggestion for a powerful ignition system such as theirs in a vehicle like yours.
Also I have used NGK plugs in my own performance VW applications with good results. I have used the NGK BR5HS in my 2213 with MSD 6A ignition. Sorry we do not currently stock this NGK spark plug.

will this replace my factory cd ignition control unit on my 67 pontiac bonneville?
December 08, 2014
If your Pontiac had a spark control box originally it was likely a dealer installed item. If you still have the points style distributor this ignition box will work and control the spark timing and also has a rev limiter. If you still have the points we also have upgrades to electronic via Crane Cams number 2881725 with coil or Pertronix number 4471181 and coil number 44745011.

should the power from the battery be disconnected when not n use?
June 30, 2014
No the main power lead going to the battery can be connected at all times. The switched power lead turns the box on and off so that it does not draw power when the ignition switch is in the off position.

will this replace a msd 6?
December 20, 2012
This box should be close in performance to the MSD 6A box and is a suitable replacement
February 06, 2011
will this work with a sbc msd distributer
February 10, 2011
Yes, this unit will work with MSD distributors IF they have a magnetic trigger or magnetic pick up. This box will work with magnetic triggers, hall effect sensors, points, or crank trigger pickups.

How does this compare to the msd 6al?? And what is the preferred distributor that I would want to use with this product in a 74 ford 2.3?
April 29, 2015
This ignition box will provide similar performance to a MSD 6AL ignition box. You can use the same distributor with this box as you do with a MSD. Distributor part numbers 91012355 and 5478473 work well with this box.

Can this be used with a msd 2step
May 03, 2016
It already has a built-in 2 step that's what the little black wire is for
June 29, 2015
Yes this will accept a MSD 2 Step.

how low does the rev limit go down to?
July 13, 2015
The dial on the side goes all the way from 0 to 9,500 rpm

Can this be used with a GM HEi distributor? The kind with the coil on the cap.
