This module makes it even easier to rev-it-to-the-red without short-shifting or getting slammed by the factory rev-limiter.  It provides 3 warning beeps prior to your shift point so you can pace your shift, regardless of which gear you are in.  No more looking at the tach and gives more warning than a simple shift light.  The "pacing" allows you to count "1,2,3,shift" and hit your shift point every time.  Perfect for Autocrossers or those who track their cars. 

New version with removable screw terminals for easier wiring

You set your intended shift point and the spacing of the warning beeps with dip switches on the module, and with a little practice you can learn to shift as close to redline as possible to get the most performance out of your car - without having to watch the tachometer.

See and hear how it works - Here is a short video of turn 6 and the back straight at TGP raceway. 

In the above video I have the Shift Beeper programmed for a shift rpm of 8900 and an 'interval' of 200 rpm.  Those settings generate short beeps at 8300, 8500, and 8700 rpm, then a steady beep at 8900.  Because the rev limiter kicks in at 9000, I have to time the shifts to occur immediately after the 4th beep.  In the video you'll hear 4 beeps when I shift from second to third, which means I waited till at least 8900 rpm to shift - that's about as close to 9000 as you can get.  The next gear change only has 3 beeps, so that means I shifted early (between 8700 and 8900).
