e38 Speedo output options (LS3 swap)

[benji808]

Hello!

I have swapped a LS3/TR6060 (2013 Camaro) into a 1986 Jaguar XJ6. I am running speedo output off pin 57 on the X1 connector, with the attached settings. I am running it through a specialty conversion box which gives me the ability to adjust speed, and it is reading directionally correct, but the speedometer bounces.

I was told I should be setting the calibration at 4000ppm, but I don't see a specific option for that.
Questions:
1) does repTOS automatically output through pin 57 at 4000ppm?
2) is there another option here that would impact the frequency of the signal that might reduce the bouncing?

Thank you!
