Knoch Hex Code

[knochgoon24]

Does any one know the hex code to get the knock count off the ECU?

Ex. MIL light is 0101. Engine RPM is 010C.

Since pocketlogger can get the knock count, I assume there must be a hex code to get it.

Ok, so after further searching. I found that you can scan the car to see what can be monitored. There are only 16 different values that you can directly monitor (on a 2g) with the ELM scanner through the OBDII protocol "Parameter IDs (PIDs). These are:

0101 - CEL Light Status
0103 - Fuel System Status
0104 - Calculated Engine Load
0105 - Engine COolant Temp
0106 - Short Term Fuel Trim Bank 1
0107 - Long Term Fuel Trim Bank 1
010C - Engine RPM
010D - Vehicle Speed
010E - Ignition Timing Advance for #1 Cylinder
010F - Intake Air Temperature
0110 - Air Flow Rate From Mass Flow Sensor
0111 - Absolute Throttle Position
0113 - Location of Oxygen Sensors
0114 - Bank 1 O2 Sensor 1
0115 - Bank 1 O2 Sensor 2
011C - OBD Requirements to which the vehicle is designed

Those are the only ones my 2g will read.

I working on finishing a write up on software reviews for the ELM327, the device often seen sold on Ebay for <$40. If you have any tips or info in the ELM software you use, send me a PM.
