Optimising the tune on any engine requires the tuner to monitor multiple parameters all in a short space of time. This can be difficult to do effectively in real time so most ECUs also provide onboard data logging to help you improve the accuracy of your tuning.

In this webinar we will look at how to use the PC logging feature on the Link G4+ /Vi-PEC ECU. We will look at how we can configure it to display data relevant to our tuning task and how we can then use the resulting data to fine tune our mapping.
