Adding switch for dual maps

Recommended Posts

Guest |471|

OK I need to add a switch for dual maps in my EVO 9, I am currently using a V44 plug in board, will then drop it up for the tuner to set up.

Having done a bit of reading it looks as though a Digital input could be used but DI1-6 are used ?

I have been given the XS Loom (expansion connector) assume this is needed ? how is the switch best set up, ie to ground ?

Thanks for any help.

Volt 6 is available on the expansion connector. This can be used as a switch input for your dual maps. The Volt input will need a pullup resistor added. This is a 1k 1/4w resistor connected to the 5 volt output on the expansion connector and the Volt 6 wire.

You would connect the Volt 6 wire to a switch that is connected to ground on the other side. In the software select Volt 6 as a GP Input. Then setup a Virtual Aux output as the switch input. If you send me your map, I will set this up for you.

What about if you want to add a switch and you do not have this expansion connector ?

I have his factory switch with 4 settings that normally controls headlight height. Simple switch that simply connects 1 wire to 4 seperate wires (4 settings) and 2 wires for illumination.

I would love to use this switch to switch between 2 maps, and 1 setting to active Launch control.

From what i read is that you can add resistors to each setting wire and make different voltages for each setting and program the system to recognise them and appoint them ?

Ray, could you give me a short walkthrough on how to do this ?

Thanks Ray !

And i could add for a 3rd and 4rd different voltage aswell (in this example) right ?

Then i would have to program Vi-pec to look for these specific voltage and assign them to specific mappings ?

Yes by adding combinations of resistor you can get four different voltages. The 10k resistor should always be used. Change the resistor connected to ground get the different voltages.

Should there be a minimal voltage difference between 'settings' in order for the system to recognize them ?

For instance, is 1 volt difference enough (setting 1= 2.5 V 2=3.5 V 3=4.5 V).

Any tips on calculating the correct resistors ? ( I triend V=IxR) but somehow i cannot work it out in your example with the resistor connected to ground).
