Msd Ignition 6A or 6AL? Does it Matter?

[sohc90adel]

I have a dilema, I just bought me the magnecor wires. I want to put a ignition system in my car like I had in my Chevy S10. Now the problem is my truck had the 6A ignition box. All I hear on this site is about the 6AL. Now does it matter at all? I already have the tach adapter and the blaster coil so basically i need some help with this before i go ahead.

the difference is that the 6AL has a built in rev limiter as well as quick accessories plugs.The 6A does not have a built in rev limiter.

I know that, but my question is does it matter?

[Aries]

if all you want it the stronger/hotter spark, then no it doesn't matter.

quick accessory plugs?..explain-

This is from MSD's site:

Quote »MSD 6AL, PN 6420 The 6AL delivers everything the 6A does with the addition of a built-in Soft Touch Rev Control. This feature allows you to set an rpm limit to protect the engine from over-rev damage caused by driveline failure or missed shifts. Other MSD RPM Controls can be connected to the 6AL such as a Three Step Module Selector (PN 8737) or RPM Activated Switch (PN 8950). The 6AL also comes supplied with rubber shock mounts and 3,000, 6,000, 7,000 and 8,000 rpm modules.Note: Same specs as the 6A except for Size: Size: 8"Lx4"Wx2.25"H

CARB approved under E.O. D-40-17 for installation in all states.[/quote]I am looking for a system to help keep me from redlining and cutting fuel from my engine. One of my friends suggested this system.

What do you guys think?

I just did some quick reading on the accessories.

One is the RPM Activated Switch. I think that is pretty cool. You can have it set with a RPM Module and have it switch something on when you hit the set RPM. I think I will hook it to a beeper of some sort.

Here is the direct description:

Quote »RPM Activated SwitchThe MSD RPM Activated Switch can be used in a variety of applications where a device needs to be activated at a specific RPM point. By supplying a ground to devices such as solenoids, lights, beepers and retard devices the RPM Activated Switch can be programmed to activate the functions of these devices at any RPM. The switch can be programmed for 4, 6 or 8-cylinder applications. The RPM point at which the activation occurs is easily adjusted using the same RPM plug-in modules that are used on the MC-2 Ignition. No RPM modules are supplied with the unit and must be ordered separately. See below for a complete listing of RPM Modules available.RPM Activated Switch - PN 8950[/quote]

Here is the other accessory:

Quote »Two and ThreeStep Module SelectorsThe MSD Two and Three Step Module Selectors permit the user to switch between multiple RPM or retard modules when connected to an MSD MC-2 Ignition or Multi-Step Retard. With this selection capability these devices can be used to perform a variety of functions.Example: When the Two or Three Step is connected to the built-in rev control on the MC Ignition, the driver is able to limit the rpm precisely while staged and waiting for the green light. By simply pressing a switch the Module Selector will automatically switch to the lower RPM module limiting the rpm at that chosen point. When the starting light turns green and the switch is released, the bike takes off and the Module Selector will switch back to the higher RPM limit. In this mode, the rev control feature of the MC Ignition will protect vital engine components against over-revving. This procedure will produce consistent and quicker reaction times. The Three Step will add a third rpm limit that can be actuated during the water burnout so that tire temperatures are kept consistent.NOTE: The Two and Three Step Module Selectors do not come with RPM Modules. Additional RPM Modules are available.[/quote]I don't think I have a need for it but it seems pretty nice.

Hope these help.

What module kit do you think would be the best?

can i fit one of those MSDs on my 96?

I could see no problems with it.

module..how about activating nitrous when you hit a certain rpm..that'd save some juice when you're flooring it around but not redlining it..i dunno..lol..just a thought...sounds dumber now that i reread it-

[1991240xs]

better yet...i'll have it turn on all my neons at 5000..that'd be tight...gotta love the pink neons-

Thing is it is just a switch. You could have a siren on the top of your car start spinning. Then your neighbors will be like "Billy is redlining again, watch out!"

"THIS IS A NEIGHBORHOOD!"

Nah, wire it to your horn, that way if your redlined engine doesn't get the cops attention, then the horn will. :pface
