Logging with Simos Tools

One of the best features of Simos Tools is it's data logging.

The logging screen offers a view of the live data. Recording the data is triggered when your pedal position goes beyond 70% so you always gather the data at wide open throttle. You can also manually record a log by having your cruise control in the "On" mode. This can be changed within the apps settings.

Log Trigger = cruise > 1 | pedal > 70
cruise > 1 = Record when cruise control is on.
cruise < 1 = Record when cruise control is off.
pedal > 70 = Record when pedal position is greater than 70%

The banner across the top will say polling when it is only reading data. It will change colour and say logging when it is recording the data. The location the logs are saved is set within the app settings.

Cruise control being on, does not mean you have it set to a certain speed. Cruise control has 3 levels in these cars. Off, stalk pushed all the way back in Audi/Skoda, switched off on the steering wheel controls on VW/Seat cars. On, is where the cruise control stalk is in a forward position for steering wheel controlled cars you can toggle the on/off switch for the controls on the steering wheel. Then the final state of cruise control is having it set, you don't need cruise control set while taking data logs.

As you can imagine actually understanding logs is a long topic so we will cover this in a range of blog posts. The important part here is that you are able to record logs successfully to review and provide to your tuner. You can find our blog on understanding the mode22 PID's here.

Logger Settings

Logger Settings

In settings you will find the logging options.

We will explain more about the different logging modes below but most people will want to be logging mode22 with or without DSG.

The log trigger settings are explained above and you can simply change them in the settings here.

Log Trigger = cruise > 1 | pedal > 70
cruise > 1= Record when cruise control is on.
cruise < 1= Record when cruise control is off.
pedal > 70 = Record when pedal position is greater than 70%

Under "Log output:" you can set where the logs save. You can then set a sub folder below if you choose.

Polling Data

Polling Data

Based on your trigger cruise control will decide whether you are reading or recording. When you are polling data the banner at the top will say polling-data. This data will not be saved.

Logging Data

Logging Data

Based on your trigger to record data your cruise control will be on/off. The banner at the top will change colour and say "logging-data". This data will be recorded and saved in your selected destination.

The logger will also automatically record when you go more than 70% throttle position. This can be disabled in settings.

Mode22 Logging

Mode22 logging is reading the PID's that are broadcast on CAN provided by VAG group. It is the same data you might be able to record with OBD11 or VCDS. The advantage that Simos Tools has is the frame rate and quantity of variables we can read. It also has some nice conversions and calculations to give a better insight.

3E Logging

3E logging requires an ECU patch. This is available for certain software versions based on the assembly code. What this offers is complete RAM variable logging giving you an even greater insight into the functions within the control unit. Using this logger requires a CSV that is specific to your version. It is reccomended only for advanced users.

DSG Logging

DSG logging has some basic variables set up. It allows you to see what torque the gearbox is seeing at the wheels. The maximum is often very high due to wheel spin. You can record this data at the same time as the ECU.
