so if You have times it would be nice function to export Nistune log with throttle position, ECT ,AFR something like this for Subaru:
Test video with Impreza on private Ice track:
I can confirm that Racerender works perfectly with Subaru logging & ecu reflashing software called Ecuedit and OBD II<->USB cable Tactrix Openport
Basically overlaying any engine sensor data you can log is possible with fast refreshing frequency. Also free Romraider program should work the same way.
