What is the difference between Tach Mode and Tachless Mode on a Remote Starter?
The difference is the amount of crank time. In Tach Mode the crank time is approximately six seconds. In Tachless Mode the module will engage the starter up to four times at an interval of 0.5 seconds. Tachless Mode saves you time during the installation due to the fact that you have one less wire to locate and hook up.
