Finaly connected the blue wire from TraqSync cable directly to indash Techometer this past weekend. Went to the track and got various results. At first the rpm would show as very erratic in TraqMate jumping to 12,000 rpm's at times. Then I started to experiment with various # of cylinders and again same results but more within the limits. I finaly set it to the original value which is 6 cylinders and it seems to work but once the boost hits the needle again goes nuts, I think there is some sort of noise being picked up, but not sure where.
Maybe I should wire directly to the negative side of the coil, but I heard it may not work on my car.
If anyone has any suggestions please let me know.
