The Relay Tune Selector allows you to program and select a second tune on your J3 Chip via any external power source – for example:
- a boost switch
- NOS or Water/Meth trigger
- LPG switch
- Power/Econ Switch, etc.
Tunes can be selected on-the-fly while the vehicle is running. This functionality can be used for low/high boost tunes, LPG/Petrol tunes, Power/Economy tunes, Valet Mode, Immobiliser, NOS, etc.
On special request we can make a selector with two relays for two external triggers.
If you need us to program multiple tunes when ordering a new J3 Chip, use the drop down to select how many tunes you need added to the chip.
