S_AUJP V7 no MPH on datascan

I'm getting there, but noticed on my datascan there is no readout of MPH. It's an 1986 Corvette that's converted to 730 ECM. So the trans sends a 8000PPM to the dash then the dash sends a 4000PPM to the ecm. dash shows MPH and with previous EBL it would scan and see the MPH, so I know it's getting correct signal to the ECM. In the XDF how would I configure it for the corvette 4000PPM signal? Thank you!

Are you sure about the ppm ? The 85 1226870 gets a 2k ppm. If your using that same signal to the 730 input c6 flag switch change magnetic pulse unchecked.

Sorry, my brain fart-it is a 4000ppm to the dash, then the dash halves it to 2000ppm to the ecm. currently c5, c6 and c7 are not checked with no vehicle speed reading in tunerpro scan data.-so c6 should be checked?
