Enabling switchable maps involves wiring in the switch, which can be found in the Installation guide; and then enabling the feature in the firmware.

To enable the feature in the firmware, set the option in the "Global Controller options", in the configuration software. Once you've enabled the feature you should see feedback in the Configuration software when you switch between configurations.

You can also define the configuration software's behavior when the configurations are switched- see the 'options' dialog for this.

Regards,

so it is the little switch in the ECU soldered into place T2???, see pic below, can i buy this part as my kit is completed already?

Nope, that transistor isn't related to map switching- and no board modifications are needed on the V3 controller to enable this feature.

Wiring the switch is covered in the Installation guide, here: http://www.autosportlabs.net/MJLJ_V3_ve ... E_3.1.0.29

ahh thanks Brent,

so i just wire it in through the molex connector and all should be good.

sweet i will look into it, this way i can have a low boost and high boost map to protect the engine on high boost and have a bit more advance for lower boost settings.

So connects the switch MAP? ? Or not? ?

Yes, that is the way that you can connect the switch for a TPS installation.

For a MAP installation you can use the same connections but you have to add R3 (1K) onto the PCB to deliver 5v to the TPS Ref connector

Martin, thanks
I will try to connect the option switch and then counting them.
