Title: Find secondary knock frequency
Post by: Wolf_Tm on January 11, 2017, 07:23:01 pm

Hi,
I'd need to find a secondary knock frequency, as the one based on bore it's very noisy on a race engine and give false knock detections.
Is there a way to export a knock audio file out of the Vems ecu?
Thanks
