"CROSSTALK" compatible - The new option named "CrossTalk" is being used in bracket racing, electronics (delay box) classes that use the full tree and handicapped dial ins. With this option, the amber lights will be focused directly at the driver in his/her lane. Each driver leaves off his top bulb (even the faster car) with no more crossing over. The top amber light in each lane will activate with the start of the slower dialed cars tree countdown. The slower cars tree will continue on its normal .5 second countdown to green. The faster cars top light will stay on for the standard .5 second duration plus the amount of handicap between the two lanes, and then it will continue to countdown after that at the .5 sec countdown to green.
Largest Lit Up Display Ever! - All numbers and text are lit up on a super large LCD display, making for the ultimate in user friendliness!
Crossover Delay Box with a secondary delay, and "How Late" - With these features you are able to double hit the tree with 1 button or 2 separate buttons. "How Late" Display will show you which "hit" launched the car and by how much.
"Tap up / Tap Down" - This feature lets you add or subtract a preset amount (of your choice) to your delay time after you release the button. (Programmable to the .01 [hundredth] on some boxes, and to the .001 [thousandth] on others). Also, you can tap as many times as you like and it will add to the total tap time.
Easy Start System - Lets you stage with your gas pedal to the floor, and the motor stays at a low preset rpm until you press the transbrake button - then the motor automatically goes up to the converter or 2-step. (Requires the purchase of a 2 position throttle control).
Starting Line Enhancer for Full Tree Racing - This feature allows you to have the gas pedal to the floor with the motor staying at a low preset RPM until after your top bulb comes on, at that point the motor goes up to the 2-step. This requires the purchase of an in line throttle stop.
Built in Digital Tach with FULL RUN REPLAY and peak rpm recorder - You can playback your entire run. The MEGA 450 has two record speeds. An optional download package is also available for those who would like printouts of their runs.
Programmable Throttle Stop Override - Allows you to speed your car up a set amount (set by you). Before or during the time your car "hits" the throttle stop, you can override a preset amount in your timer. You set it up to subtract a certain amount of time, and have the option to override or "subtract" as many times as you wish.
Shift Activator Output - The Shift Activator Output allows you to shift on Time or RPM up to 5 times. RPM is adjustable to 50 rpm increments. You can shift as much as 5 different times, at 5 different RPM's. You can even split the shifts - some could be by RPM, and some at time. This box is legal, but this feature is Not legal in all sanctions.
Reaction Time Tester - Allows you to practice your reaction times while sitting in your car and using your own button. A true reaction readout is displayed.
Push Button Interrupt Time - A preprogrammed feature which prevents the transbrake from turning on if the transbrake switch is accidentally touched.
