Rotary switch

Interested in full Rotary switch support as well, so we could alter for example traction control slip %, als setting ect without the need off VA

You can already do that. Just setup a anloge input for rotary switch. Use eighter direct voltage or use a calibration table to output position. 

Use rotary voltage or position as an axis for launch rpm, traction aim, boost aim, etc.

Never thought of doing this through a cal table, good point. Could be easier though if we could just select rotory switch as an an function followed by: numbers of positions, threshold and then a simple table to define each position

Really like that idea, which rotary switch's are people using?

We use up 4 rotary switches on some cars. 

12 pos Launch RPM

12 pos Torque Maps, VA to switch between 3 boost strategies (TP, RPM base, straight) with several Boost Targets. Alter IGN on some maps.  

12 pos Traction Control Targets

3 Pos Switch for different E-throttle Targets

You can do quite complex setups and much more than the Average Joe may think is possible with LINK. Only limiting factor is the overal number of 30 tables. And 4D,5D,6D would be nice for boost. I would also like to have a few more Fuel and IGN overlay tables (7D,8D,9D...). Same for traction control.

Another question, doesn't the value interpolate between positions if the input value differs a bit for some reason, compared to the calibrated value?

It is connected to a regulated 5V supply and is a fairly simple voltage divider network with detents forcing it to fixed positions.  It should be repeatable to within a few hundredths of a volt, so there will be almost no interpolation provided your cal table is set up correctly.

If you use a calibration table with Volt input and integer position numbers (1-12) output, the output does only change in steps of 1, so no problem between interpolating. However, if you have a 12 Position Switch for example Launch RPM, the Launch RPM would only change negligible little.

Yes indeed, what brand Rotary switches do you prefer?

I'm using AEM 30-2056 and for Highend Application Motec 9 Position. Doesn't matter much which one you use, it just should give you signals between 0 and 5 Volts. 

Besides, Adamw / Link ECU that would be a nice Accessory in your product lineup!
