I recently acquired a tuned megasquirt with full engine and all the goodies.
It did not come with Wideband so I ordered an AEM UEGO Wideband Part# 30-4110

It uses the Bosch 4.9 LSU Sensor.
It does not appear to be linear here's the table I got from the manual (you can also save this as a .inc file
Code: Select all
