MSD Ignition Three Step Module Selector (universal)
90% of the products in our store are in internal or external stock and we can often process your order quickly (varying from a few hours to a number of business days).
Naturally it is possible that a product has an (unexpected) longer delivery time.
Upon receipt of your order, we will always inform you about this and offer any available alternatives. So keep a close eye on your mailbox.
We deliberately provide stock information about our products afterwards, because many suppliers do not offer a ''stock link system'' and we do not want to show '' estimates '' in advance, like many other webshops do (which are often incorrect and give you wrong information in advance). We only want to give our customers actual information on the moment of processing the order so we don't mislead our customers.
If you need a product VERY quickly and you need to be sure that we have it in stock, please e-mail or call us or send a message via ''ask a question about this product'' below in the product description.
The MSD Module Selectors allow you to choose two or three dif ferent 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 Selec tor 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 consis tent 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 acti vate 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.
