Hey Micheal,can you give me a few pointers too?

Hopefully nobody get their panty's bunched up,

The pressure switch is plumbed into the rear brake hydraulics, the pressure switch turns on a pair of LED lights mounted at the top of the windshield, one in the center near the rear view mirror and the other on the L/H side, of course you will need a brake pressure gauge to set the switch with, the idea is to be able to see the light out of your peripheral vision, another thing that does not require your total concentration. The two step is connected to the factory brake light switch, I know a lot of people mount a switch to the brake pedal and use their foot too step on the switch the reason behind that is when you start scrubbing of that .002 on the top end you don't turn the two step on again by hitting the switch,....the .002 you were holding will turn into a tenth by turning the engine off and of course cost you the race.

I mounted a micro switch to the shifter that opens the two step circuit when the trans is shifted into high and prevents that. I have the part number for the pressure switch around here somewhere, I'll see if I can find it.

I have been using this setup since the 80's and I saw on an old F/SA Fairlane stocker that won the Winternational back in the 80's, guys name was Dan Rienhold, I just improved upon what he had.

Just a little extra what ever, the MSD two step that I use is old, newer setups may not do this, lets say you have a 3400 rpm chip in it, if you activate the switch at say 5500 - 6500 rpm, it just shuts the engine off. The only reason I mention this is, years ago when racers first started using two steps on the starting line, I heard that some were using it as a down track E.T. adjuster....to slow the car down. My experience with two steps.....that would be really hard on the engine, might work for a little while, but you probably will be doing some funny car type maintenance on engine parts.

Lane, you don't need any lol.

When I was using the 2 step last year, I had the MSD Adjustable RPM module/pill in mine. I set it at 1800 and the engine never stumbled once. What I did notice is that it blackened the plugs terribly.

On a stick shift car the 2 step will help keep the clutch consistent, the motor will stay clean and it saves excessive wear and tear on the valve train.

As you stall up the converter, the boost comes in, so then the stall speed increases, then more boost and so on ,until the brakes no longer hold . The 2 step caps off that process at a predetermined point, in my case ,about 3800 rpm.

Mark, I'm interested to know what kind of braking system you are using. I am running a '88 Thunderbird Turbo and can only get the brakes to hold at 3000 on the two step. Thanks for the help. You can instant message me the info.

Marco, I'm using an original 79 manual brake firewall adapter , m/c and rod, and an automatic pedal, modified to to manual specs (all thanks to Mr Rory Mc Neil)
Factory discs, lightened, and aluminum drums on the rear.
Quite possibly, your converter is not loose enough, or the wrong configuration.
