Hellen64 revb 91Miata VSS

[Kristian]

Hi, I've wired up temp VSS signal from the dash. I have confirmed that the dash output is 5 volts when high, and 0 volts when low, and that it switches state as the car moves. I have hooked the wire up to 1M, VSS input, I have configured tuner studio to use 1M as VSS input, but I cannot see a vehicle speed reading on the data logs. I've looked at the spaghetti diagram and I can see an input called VSS IN, connected to P33. I can see the pull up resistors R20 and R23, but if I test between these resistors (in particular R32) and P33, I read some 14K Ohms. should this be less or am I misunderstanding the design? Do I need to run a link between P33 and R32 to get VSS to work?
Thanks in advance.

Just made an improvement in the firmware - at least we will have VSS front event counter https://github.com/rusefi/rusefi/issues/4173

But did not have a chance to test it so far

Ill update tomorrow with needed jumper for vss

Sorry for the delay. Remove r20 and jumper to p33. VSS circuit already has the pullup, so r23 can be completely bypassed.
