Extra O2/EGT JS4/JS5 confusion

Post by AncientGeek »

The Ms1 hardware manual at http://www.msextra.com/doc/ms1extra/MS_ ... .htm#2ndo2 claims that extra O2 sensor and egt logging cannot both be used as they use the same adc. But extra O2 uses JS5 (X7) while egt uses JS4(X6).... ? :?:

in fact... JS5 is also used for realtime baro and fuel pressure (undocumented). JS4 seems only to be using egt logging. Also X7 is actually X6 on the processor, and visa versa.

Since I'm already using realtime baro on JS5, looks feasible to hack the code to use the extra o2 on JS4. One day, maybe.
