MSD Ignition 8739 Multi-Step Module Selector, 2-Step

  • Allows a launch rev limiter and a high speed rev limiter
    • 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, we’ll 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 you’re 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. No rpm or retard modules are supplied.

    Concept Car of the Week: Lamborghini Marzal (1967)

    Fri, 14 Dec 2012

    In 1967, Lamborghini's lineup consisted of just two cars – the Miura and the 400 GT 2+2 – but this wasn't enough for Ferrucio Lamborghini, who fancied a true four-seater GT to add to his stable. After the successful collaboration on the Miura, he naturally returned to carrozeria Bertone which was commissioned to design the car. The project was left in the hands of Marcello Gandini, who turned Ferrucio's vision into a revolutionary design concept.

    Recall is last linked to fire hazard, Ford says

    Wed, 14 Oct 2009

    Ford Motor Co.'s new recall of vehicles that pose potential fire hazards will be its last because the latest action covers all remaining cars and trucks with cruise-control switches made by Texas Instruments, even if those switches don't pose safety risks, a Ford spokesman said today. "We did this to reassure customers and make sure there will be no future actions connected to this," spokesman Wes Sherwood said in an interview. "We've gone to extra lengths to include both vehicles with risks and those that don't show risk." Yesterday, Ford announced a recall of 4.5 million vehicles--its eighth in the past decade involving cars and trucks with faulty cruise-control deactivation switches.

    Chrysler reveals 200C electric vehicle concept at the Detroit auto show

    Sun, 11 Jan 2009

    Chrysler LLC jolted automotive journalists ready to see the world premiere of four production-vehicle-based electric cars and trucks at the Detroit Auto Show, adding a surprise electric show car dubbed the 200C EV. Chrysler co-President Jim Press said the 200C and other electric vehicles show "there's evidence here of ongoing investment in the future." The stylish concept car features the same range-extending electric drive system deployed in several other production-intent Chrysler EVs revealed at the Detroit show, including the Town & Country EV minivan, Jeep Wrangler Unlimited EV and Jeep Patriot EV. Chrysler also unveiled the all-electric plug-in Dodge Circuit EV, a Lotus Europa-based electric concept with an estimated range of 150-200 miles.
