LinkG4+ Gear detection
First time posting on thread.
Running a link ecu and I want to setup a gear detection so I can use my digital display with gear display. I've tried analog and played with the voltage but it doesn't work. Anyone got a clue on how to set it up?

You may have better luck asking in here: https://www.rx7club.com/link-vi-pec-297/
I'm not sure what the Link capabilities are, do you only want an indicated gear (RPMxSpeed calc), or are you hoping to set up a flat-shift/auto-blip type situation?

This is the config for the FD VS sensor wired to DI#1; your calibration # may be a little different if your tire sizes or gear ratios differ from mine. I calibrated mine by driving a steady speed, and using a GPS/nav app to monitor my speed, set the cal # so the speed displayed in PCLink agreed.
This is the layout page & settings I have for my gear detection. Your #'s may be different if you have different gear ratios & tire sizes.

Neither of the above options work for me (since I'm out of available analog inputs), so I haven't deep-dived that feature any further. But I think it's possible. But to do it, and to enable similar features such as traction/launch control, you would need to provide a non-driven wheel speed input to your ECU. Did a little research on this using the OEM ABS sensors on the front wheels for that, but the issue there (at least with the Link G4+) is the frequency output of the factory ABS sensor & ring combo is too high - so you would need to add an external frequency divider/conditioner circuit to divide the ABS output pulse frequency by 4 or 8 to make it usable.

#2 isn't a great deal as it's all up to calibration
as for #1 the wheel speed sensor, I do have my abs or LR wheel as one of the DI. But it doesn't activate when wheels are spinning which I assume it just straight up doesn't work. As for now I just need to know how to get my speed sensor on the tranny to wire it into one of my DI's

after setting up Digital 1 to read the digital sensor on the tailshaft of my trans i tried both methods and eventually let the automatic method set my 3rd gear. i then just did the math for the other five gears (Tremec Magnum F) and filled in the blanks. i use the "DisplayLink" as my digital dash. my primary objective as to getting the gears synched was to do boost by gear. i have a G4X Extreme but i am pretty sure the system is similar.
