Activating Map2 and switch function

Post by Litle brother »

Hi.

Can someone help with how to enable / set up Map2 and the switch on the S80Pro so it will be possible to switch between Map 1 and 2 ?

Cheers

Connect a switch between sensor ground and pin 15.
Go to MAP2/ALS Parameters and check the Control On option, and the Always Activate When Switch On option.

Then set up the primary and secondary maps.

That's it.

Is it sensor ground pin 21 or 33 I shall use? From the wiring diagram I assume it is pin 33 ?

It doesn't matter which ground pin, they are common.

Thanks Rob :)

Then just one final question: can I switch between map one and two on the fly or must the ignition be off?

It seemes I have one more question. My ECU is placed under the driver seat and I want to mount the switch on the dashboard. That means that the total lenght of cable from ECU to the switch and back will be approx 400-460cm long. What gauge size will I have to use?

Cheers

It carries no load, for sensor cables lately I've been using 0.35mm^2, but you could use heavier if it is more convenient.
