Analog input multiplexer
Extends the number of analog inputs by +6 (on v3: 16 =>22), usable for anytrim input channels.
Contains 8=>2 (actually 2 x 4=>1) analog multiplexer.
Address selection is done with 2 (logically-neighbor) low-side switches, eg p259/6,7 (or, when ordered together with ECU v3 and "v3 with internal inpmux using flying loom connector" requested in order comment: internal signals p259/2,3 that are inside the box, not normally connected to econoseal pins anyway).
Can be tested with DVM, by grounding the address pins.
See VT Help. NOTE: analog input multiplexer is for advanced users only (new fw required, "analog input raw" might show lower or higher than real: might need calibration in VT, perhaps with ini-tweaks to show 0-5V for 0-5V input especially if internal pulldown is in effect eg on mcp3208/ch1 ; onboard pullup/capacitor might need to be removed: certainly if the inpmux was not ordered to be in installed in VEMS ECU/mainboard ). For most purposes, the 8 extra analog inputs should be enough.
If running low on analog inputs, instead of this inpmux, possible to order with order comment: "all possible analog inputs + third trigger(HALL type) + wheelspeed2": those can be used for ALS/launch activation inputs (free of charge).
Matching DSUB15 female connector included.
