Title: RPM signal for a sequential shift light
Post by: Rockingdad on October 26, 2018, 14:17
Hey everyone, I'm after a bit of technical info on the RPM pulse provided by the ECU. Does anyone know if our MR2's provide a square pulse wave for RPM's and if so what wire out of the ECU provides this?
I'm looking to install an arduino driven sequential shift lift because.....why not 😁

Cheers
