Getting MS3 to read VSS & Gears

[shaodome]

So MS3 has the ability to poll the can bus for the VSS, but I frankly have NO idea how to set it up and cannot find any documentation anywhere to help.

Ok, so I drank some coffee and looked into the INI file further....

for the CAN stuff on Megashift it looks like the gear offset is 12 and the VSS offset is 2. (Lance please confirm). What I don't know is the datasize (8bit vs 16bit) and what to set the scaler% to in the speed/gear settings. James has the tooltip that says:

Number of pulses per mile/km or scaler to convert from one unit system to another. (Megasquirt uses 0.1 ms-2 internally, so to convert from 0.1 mph use 45.6%

So would that mean just use that default value of 45.6?

shaodome,

See this thread: viewtopic.php?f=4&t=880&p=4680#p4675

You would have to ask the MS3 developers about the scaler, I have no idea about that.

Here is an other post with my settings for MS3 and MSGPIO:
viewtopic.php?f=4&t=850#p4507

The scaler is to convert the unit from MSGPIO(mph) to m/s (meter/second)
1mph = 0,447m/s
