    My Auto Meter VSS works perfect for the ECU, Digital Dash, Datalogging & I/O.

    That means datalogs recorded with the Digital Dash, as opposed to the ECU or laptop.

    I found this for a great way to adapt to a C4 or manual transmission to use the Auto Meter signal generator. Hope this helps someone out.

    Yes, that will adapt to the older style threaded speedometer cable/Auto Meter 5291 VSS.
    If you have the newer style plug-in speedometer drive cable, Auto Meter sells it as one piece:

    I have a HP ECU and just installed the Holley 556-106 Digital Dash. I have a digital speed sensor that displays correctly on the laptop gauges, but won't display on the Digital Dash at all. Do I need the 554-140 GPS sensor? Or is there a way to configure with my existing components?

    No.

    You just don't have it programmed correctly. Ensure you've selected the correct data channel ("Value To Monitor") for the gauge. Scroll down toward the end of the list for your custom I/O. Example: Don't select "Speed" (which is from the Transmission ICF), if your VSS is from the custom Inputs/Outputs ICF.

    This happened to me as well. The Value To Monitor that I created for my speedo wasn't there. I ended up updating the Digital Dash and the HP EFI to the latest ECU firmware & EFI software and it was there. Danny, thanks for all your help through posts & responses on here. Helped me out a lot.

    You're welcome, I'm glad you got it working.
    May God's grace bless you in the Lord Jesus Christ.

    Got to kick this one again and get the holes filled in my brain, since I've never completely done this and it's taken two years to get the car driving with the wreck happening at only 70 miles back on the road. I thought I had to set this up on my T56 Magnum custom, so I setup a VSS input IPU Speed/Freq with 17 Pulses To Average and 17 Pulses with 3.73 Gear Ratio & 25.7" Tire Diameter. At some point I got more info and loaded the Transmission ICF. It's set to 4L60/5E, max RPM of 7800 and speed of 300. Ignored the rest except the Speed Calculation, Tire Diameter again 25.7", Rear Gear Ratio 3.37, Speedometer Output Enabled with 4000 Pulses Per Mile (got that from factory manual). So this gets me a speed on my stock speedometer which is unstable. Do I need a pull-up resistor on this signal wire? Also, one on the loaned 5.7" LCD Touchscreen, the readouts were completely off and I messed with it and finally with a Gear Ratio of 1.62 it reads just .5 to 1 MPH high. The computer and display are stable, Camaro speedometer is all over & useless, so that's why I'd guess a pull-up resistor is needed?

    So, now I've got it back on the road and I'm driving it again without mufflers. I've got it working well enough that I thought I'd get this right while doing more break-in miles. I tried setting the Transmission ICF to 3.73 Gear Ratio and I changed the number of pulses in the VSS input, but that does nothing. So now I'm thinking the Transmission ICF is pulling that from the T56 and it has the wrong count, but that's not good. I'm going to have several different wheels for this thing and I'd like to just change the Tire Diameter and be safe to drive down the road without using my phone to track my speed. I could be wrong, but I'm thinking the 1.62 Gear Ratio to make the 25.7 work sort of right probably won't be right when I change to a 28" drag radial or whatever size my autocross tires end up being.

    I might end up needing to get some sort of digital dash, but they all suck for different reasons and one same reason cost. The IQ3 Street Dash is mono-color for $1000, really? The Holley isn't much better on price and has a great color display, but lacks on a tone of other indicators for a street car, and does it have an odometer? They all lack my features, I'll keep that to myself for now. Maybe you can help with one other thing real quick the speedometer is almost useful if you compare it to the way the tach is acting. Does that also need a pull-up resistor? I know these gauges worked with the stock engine & ECU, and that is why I expect it's an issue with the install and not them.
