ALPerf Posted May 10 Report Share Posted May 10 Hi all Can anyone tell me how to set up a rotary map switch please, I have a the switch set up as a GP input and have got it working within link PC, I've wired it up to anv 2 and 5v sens ground, using cal table 1, switch is moving through positions nicely, my struggle is allocation to the 3 boost table's, they seem to want a DI input but this would only allow me one extra table, also I'd like to include a race fuel map at position 4 any ideas how to set the logic up please Many thanks Adam Quote Link to comment Share on other sites More sharing options...
Laminar Posted May 10 Report Share Posted May 10 Here's one way I can think to do it - map some GP Outputs to read your knob position and activate virtual aux signals. For example, if the knob position is 2, turn on Virtual Aux 6. I added some greater than or less than in case a little noise makes it not exactly equal to 2. Not sure if this is necessary, but it felt safe: Do the same so that when the knob is at 3, we turn on Virtual Aux 7. Now set up boost with 3 tables and use your virtual auxes to activate each table. Depending on how much different your maps are from each other, you could also use a GP trim table with your rotary position as the y-axis. So you could have three independent maps and the possibility of a trim table on top of one of those maps: In this case, your boost target would be equal to table 1 + the offsets in the knob position 4 row, you'd do the same for your wastegate trim table. If you wanted the race gas map to be a trim on top of map 3, you could expand the definition of virtual aux 7 to be >2.95 and <4.05 so that table 3 is active in knob positions 3 and 4 and the trim gets added in position 4.
