Note: MaxxECU saves 4K data each time, if you have selected a very slow logging frequency, a few channels and enable loggings for a very short time (< 10 seconds), MaxxECU might not capture any data (no file to download), in these cases, run the logger a few seconds longer to capture the data (like using an off delay if the logging system is triggered from an internal output or GPO).

ECU logging settings

 

Enable logging

Enable or disables internal logging functionality

 

Logging start

Internal logging can be activated by different options:

Always on - Logging is active as long as ECU is powered on. A new file is created each time the ECU is reset.

By switch input - Starts by triggering the digital input Start logging input function.

By launch ctrl switch, log 60seconds - Starts by triggering the digital Launch control switch, enable stage input function. Time starts when input is deactivated (button released).

By launch ctrl activation, log 60 seconds - Starts when all MaxxECU launch criteria are met (launch active).

Note: If launch ctrl switch digital input functions is triggered during logging, additionally time is added to the actual logging feature.

 

Switch activation can be triggered by one of these three methods: Digital inputInternal outputs or Virtual input.

 

Logging frequency

Specifies at which internal frequency the logging is being operated on. 10Hz = 10 times/second

Note: Only values that are changed is stored in memory, this is done automatically by the ECU to save space. Ex you have selected 1000Hz logging speed, CLT might vary 2-3 times during a second, but wheel speed might change 500 times, then 500 wheel speed values but only 3 CLT values are stored in the memory, but when downloading, what you see is full speed.

 

Number of channels

Number of channels to log.

Note: Earlier MaxxECU units are limited to 44 channels, all REV7 and newer units are able to log 118 channels internally.

 

 

channels to log

 

log channel x

Shows which engine data value is to be logged on the actual channel.

 

 

Note: When memory starting to fill up, before write of a new file, the oldest ones gets deleted automatically.
