Digital Delay Mega 450 V3



Introducing, the Digital Delay Mega 450 V3 Delay Box.

We upgraded the popular Mega 450 by adding some new racer-requested features, including our Set and Go push-button mode which is similar to Z-Force* - the press of a button (SET) sets the Transbrake and then on the press of a separate second button (GO) starts the delay timing.

Additional new features are, the ability to Tap Up and Down on the same pass. The setting of the S.L.E. by the Transbrake pushbutton can now be turned off.

The Replay Tach can now record up to nine passes and replay them on the screen.

Bracket and Pro Mode both have two 4-Stage Timers and can shift up to 5 times by RPM or Time.
