I am new at the whole racing thing and want some advice. My brother is thinking of putting a 2step on his car. he has a msd 6al with a soft touch rev limit control and a roll control. its a 4 speed car. how hard would it be to hook up a 2 step. what do you do to hook one up?

All you need to do is pull the RPM pill out of the MSD-6al and plug the two step module into that plug. plug in your low RPM pill into plug #1 on the two step module and your max RPM pill into plug #2. Connect the ground (black wire) out of the 2step to the frame or ground connection. Connect the Red Wire from the 2-Step module to one side of a single pole normally open button then from the other side of the button to the 12V power feed. When you press the button it causes the 2-step to enable the low RPM pill. say 3000 RPMs. this will cause the MSD ignition to to misfire motor. The driver can then put his foot to the floor while holding the button down and the RPMs will not go past 3000 RPMs. When you are ready to launch let off of the button and the two step switches to the max RPM pill and you are ready to rock. The only problem with a 4 speed car is you have to do two things at once. Let go of the button and pop the clutch at the same time. Pretty tricky if you ask me. Unless you can wire the button to the clutch pedal. might be a little tricky and take some tweaking. And BE CAREFUL or you may hurt your motor. Most racers run a automatic trans with a transbrake and launch the car off of a button only.

I use a 2-step (activated by a button on the shifter) with a 4-speed... and wouldn't do it any other way! You just lift your thumb and clutch foot at the same time. It's no big deal. It's a LOT easier than modulating the throttle at launch.The 2-step allows a stickshift to take off with the throttle wide open. Without the 2-step, the car launches with the engine at part throttle... which usually gives a -weenie- start. With the rpms up AND the throttle WFO, the car takes off with some authority! Hooking a nitrous system to a throttle activated micro switch, really makes things happen quick.  To keep out of the nitrous while staging, I've had to launch at 3/4 throttle, but I've recently learned how to wire up a couple relays together (nitrous & lineloc/2-step) to allow the throttle to be fully WFO taking off. I found the diagram here... http://www.geocities.com/scottinal/Nitrous_Activation_Circuit.gif Here's his whole site... http://www.geocities.com/scottinal/ Good Luck! ------------------

i like the msd 2-step in my car, not that it helped me hook...that part im still working on. it takes out a lot of variables in launching a stick car to help you tune your launch (which im currently doing). ive got mine on the shifter, when the light changes i let out the clutch first. the rpms will drop below the rev limit momentarily so you get about a second to let your thumb slide off the button. dont have to buy that high dollar ($40) switch with the fancy swiveled black electric cord to hook it up. got 2 swithes at radio shack for like $2 and wrapped the wire around the shift lever to a sweet switch mount that i could be a gazzillionaire if i market it. it allows you to keep the classic looking hurst white ball on top and still have the switch mounted conveniently for your thumb and its trick, hidden, and doesnt get in the way during bang time. actually my neighbor thought of it, handy old fart.------------------
