You are correct, wheel speed is not helpful here and a user defined equation is the best way to handle this.

Except when you are using a low power processor and have four frequency inputs coming in at up to 2khz, it is much quicker and easier to log the time between pulses then to convert to a frequency. Do the processing on the PC end where it has more time and power available to do it.

I have a feeling that this could be a decimal separator issue. The , separator is for when the decimal separator is set for . If you have your decimal separator set for , then try using ; instead of , in the argument.

I agree that if it was being handled in the data logger then that would be a reasonable way to do it.

The format of the IF statement is if(x,y,z) where x is the equation being evaluated, y is the result if true, z is the result if false. So it would be something like if(VAR_7008=0,VAR_0316,0) This would return a value of VAR_0316 if VAR_7008=0, otherwise it would return a value of 0. Martin

The system monitors the voltage level on the pins. When connected they will have an external pullup on them, so when the outputs are not activated the voltage will be high. If there is nothing connected the voltage will be low, which looks exactly like the output driver is turned on. So the system k...

I am not sure what you are disagreeing about. The spec for the frequency input messages is here: https://www.race-technology.com/wiki/index.php/DataAndConfigurationMessages/14-17FrequencyInputs As you will see, it is stored as a time period between successive pulses in multiples of 1/6 us. 3 byte co...

Yes the PIDs are common across cars for the OBDII interface. They are not transmitted continuously by the vehicle though, they are only sent in response to a request. As such, you will need something which will send the request to the vehicle and then decode the answer when it comes back. The typica...

The DL1 doesn't log the frequency. It logs a counter value each time that a pulse arrives. Whatever is looking at the data from the DL1 then looks at the time interval between the pulses and calculates the frequency. If there is no pulse, at what point should the DL1 say that there is a non-existant...

I believe that there is a way you will be able to get what you want, but not in a direct way. Have a look here: https://www.race-technology.com/wiki/index.php/DL1MK3Configuration/VariableMapping Look at the section right at the bottom about the order in which values are calculated. This makes it pos...

The only instance in which the CAN adapter would add anything in your setup was if you wanted to get the data off the OBDII bus through the vehicle CAN bus. This can't be done from the DL1 directly. As you mention, the big problem you will have with connecting directly to the vehicle CAN bus is not ...

Which version of the DL1 are you doing this with, it is one which logs to an SD card or CF card?

Martin

Where are you looking at the data from the data loggers? This timeout is more a function of the display than the data logger, as the data logger is designed to record and count the pulses. There is no method for it to log not having a pulse. As such, any timeout would need to be incorporated in to t...

Hello

This means that control output 4 is configured to be use, but nothing is connected to it. To get rid of this message, simply reconfigure the Dl1 with control output 4 disabled.
