Over the winter I wired a new tach into my car spliced into the same signal wire off of the ECU that I used for my G2X data acquisition (which is for sale if anyone wants one used - PM me before I ebay it).
On the video of my tach the signal drops to zero between shifts. When I had my G2X in there and looked at the data it was similar to the in-console tach - there is the obvious drop in revs but it doesn’t go to zero between every shift.
Anyone know why this happens and an idea what I could do to fix it?
