How to Datalog battery voltage

Post by BottleFed70 »

MSII V3.0 Megatune 2.25b748

Does anyone know how I can add BattV to my logging?

I'm trying to troubleshoot a tach signal problem (reports 0 for a few lines and nearly stalls the engine) and I'd like to see what the battery voltage is doing during this time.

Thanks!

Bottlefed70,

See this for battery voltage logging: http://www.msefi.com/viewtopic.php?p=94 ... batt#94115

(Note that 'batteryVoltage' also needs to be in the 'Output Channels' in the INI file, but it should be there by default in MS-II in a line like:

batteryVoltage = { batADC / 255.0 * 30.0 } ; Current MS power supply voltage.

)

Lance.
