Motec M4 configuration

These settings have been tested by one user, please let me know if they work for you.

On the misc-2 setup it shoud be log set 2 and logging rate 10/sec.
But the input from a external wb controller is V-lin.
This required the following setting to the M4:
Lambda control: 0 (off)
Lamda: -1 (user defined)

Then on the - "sensor setup" - "sensor calc table" - "lambda sensor" table:

Lambda  Value
50              100
55              100
60              100
65              100
70              133
75              208
80              283
85              358
90              430
95              510
100             584
105             657
110             735
115             819
120             900
125             972
130             1041
135             1111
140             1188
145             1200
155             1200
160             1200
165             1200
170             1200
175             1200

This are calculated values from the v-out table from TechEdge and a
formula on the help (F1) screen on the M4.

Here is the data which get logged (log set 2 on M4's) on the current setting:

rpm
throttle
MAP (I use it for baro comp)
ET
AT
Bat V
Lambda
Speed 1
Fuel Duty Cycle
Accel Enrichment
Aux Duty 1 (use it for the e-water pump)
Errors
