  • MSD 8732 2-Step Rev Control for Digital 6AL
    New
    MSD 8732 2-Step Rev Control for Digital 6AL
    SKU-5478732
    x
                Since the new Digital 6AL Ignition uses rotary dials to adjust the rev limiter, our engineers were tasked with developing a 2-Step Rev Control that could be added to give racers the ability to switch to a low rpm limit to use on the starting line.    The new 2-Step is also digitally controlled and connects to the Digital 6ALs gray tach output wire. There are two easy to read rotary dials that let you set the launch rpm in 100 rpm increments. There is an activation wire that connects to the transbrake, a clutch switch or to the line-lock to activate the low rpm limit. When that switch is released, the low rpm limit is turned off and the car launches hard!

    MSD 8950 RPM Activated Switch
    SKU-5478950
    x
                These RPM-Activated Switches will perform a variety of different functions from turning on a bulb or solenoid to activating an MSD Timing Control at a desired rpm.The RPM-Activated Switch, PN 8950, has two activation wires; one to ground a circuit and the other to open a circuit. Simply plug in an rpm module and wire the Switch to the circuit you want to activate. When the engine rpm reaches that amount, the circuit is activated and will remain on until the rpm falls below that amount.The RPM Window Switch, PN 8956, has two rpm adjustments; one to activate a circuit, while the other deactivates the same circuit. This Switch will supply then remove ground to a circuit. This is a great feature to deactivate nitrous before the engines rev limit is reached. Both Switches can be used with stock inductive ignitions or an MSD Ignition and can handle up to 1.5 amps. No rpm modules are supplied so they must be ordered from the selection of Modules shown on page 124. For use on 4, 6, or 8-cylinder engines.

      MSD 8970 Three Stage Retard Control
      SKU-5478970
      x
                  The Three Stage Retard Control allows you to retard your ignition timing in three different stages. You can activate one retard for a nitrous stage and another at top end in high gear for more mph and still have another module left over for dual stage nitrous systems. When activated together, the retard amounts are cumulative so you get the total of the three. For example, if you pull 2�, then 4� on the second stage and another 2� at top end, the total retard is 8� (2+4+2=8). In addition to the individual retard stages, the Three Stage Retard Control has an optional start retard function that retards the timing 10� or 25� while cranking the engine. The Three Stage Retard Control connects easily to your MSD Ignition and can be triggered from points, electronic ignitions, crank triggers or magnetic pick-up distributors. It is supplied with a 2�, 3� and 4� module and must be used with an MSD 6, SCI, 7, 8 or 10 Series Ignition.

          x
                      This stand-alone microprocessor boost control�ler is exactly what-over-the-top turbo powered cars need. This Control uses an extremely fast microcon�troller to control boost pressure via an electronically operated waste gate valve.Through easy to use Pro-Data+ software, you can control the amount of boost pressure used during the burnout and map a boost curve based on time for the launch and entire run. Control over the boost pressure is achieved through a PWM output that controls a three-way electrically operated air valve that is installed between the turbo and the waste gate actuator. (This can also be programmed to your particular actuator.)To help in setting up and tuning the Controller, there is also an acquisition file that records the engine rpm, manifold pressure and the pulse width modulator output. After a pass you can save and download the file to review each pass.

          Installation Instructions (PDF)

          • Absolute control over a turbos boost pressure during the launch through advanced programming
          • Map a boost pressure curve based on time from a PC
          • Ideal to control boost pressures during the holeshot to aid in getting the tires hooked

          MSD 8739 Two Step Module Selector
          SKU-5478739
          x
                      The MSD Module Selectors allow you to choose two or three dif­ferent rpm limits that can be activated at different times. With this ability, the possibilities are endless.As an example, well use a drag car with a Three Step Module Selec­tor plugged into the rpm socket of a 7AL-2 Ignition. The different rpm modules are activated when 12 volts are applied to a corresponding wire. By connecting one wire to the line-lock circuit, one module will be activated during the burnout. This helps keep tire temperatures consistent. When the line-lock button is released, the limit turns off. When youre on the starting line, you can activate the second limit through the clutch or trans switch. This provides a steady and consis­tent rpm for firm holeshots every time. When no modules are selected, the remaining high limit is active to protect the engine in the event of driveline failure. The Two Step works the same, but only with two different limits.The Module Selectors can also be used with an MSD Timing Control. By plugging the Selector into a retard module socket, you can acti­vate different retard amounts at select times. This is a great feature for engines being upgraded to a multi-stage nitrous system. With the addition of an RPM Activated Switch, you can use the Two Step to activate a shift light at different rpm.The Module Selectors must be used with an MSD Soft Touch Rev Control or a Timing Controller with a high-speed retard module.

                          This 2-Step connects right to your late model Ford to produce consistent launches and quicker 60-foot times by setting an rpm limit to stage with. When activated, the rpm will be held at a steady rpm and once the green light comes on, release the clutch and take off - but be sure to hold on! The rpm is adjusted with two built-in rotary dials ranging from 1,800-9,900 rpm in 100 rpm increments. A handy LED shows when the launch rev limit is active.  Installation Article: Dragzine

              These MSD Digital SCI Plus ignitions deliver high output Capacitive Discharge (CD) sparks for complete fuel mixture combustion, especially at high rpm. They feature a retard stage to handle nitrous, making sure you don't get detonation from increased cylinder pressure, and a rev limiter that assists with firm launches. The 15 MHz micro-controller is the fastest of all digital ignitions, and gives you a smooth rev limit and precision timing. Easy-to-use rotary dials make adjusting the launch limit and retard amount simple and easy. MSD designed them to install easily on most 4, 6, or 8-cylinder engines with a distributor.
