I'm guessing that's data logging speed, nitrous related to speed, etc.

I have a 4L80e on a Holley Dominator ECU, set the pulse at 10,000 ppmile, using a SpeedHut speedo. Not sure if that helps you or not but figured I'd mention it.

EDIT: I have a trans output set on J1-B12 as PWM for the speedo.

I need to add a datalog input for speed, haven't figured that out yet, but haven't tried too hard yet.
