Help please, can't seem to get speedo to work in adx dash.

**37chevrod** · 08-09-2013

Hi everyone, Thanks to this fantastic site I've been able to get my streetrod running quite well,not that it's been easy or that it's finished, but getting closer. I'm using a dakota digital dash with a digital speed interface on a 700r4, the digital dash is working great, but I can't seem to get the interface to communicate with the 7730 ecm using $8D bin or get the interface to communicate to the dash that I've built in the adx file. The digital interface has signals of 8k 4k and 2k available. I've tried hooking up the 4k signal to the ecm terminal B10 still nothing. also I'm using an autoprom, and everything else on the adx dash is working. Any insight would be greatly appreciated. Thanks in advance

B10 is used with a magnetic VSS(or at least that type of signal, which is AC). for an optical signal(or DC), you need to connect to pin C6.

Thanks for the quick responce Robert. I repinned from B10 to C6,and still no data on the adx dash. Do I need to edit the vehicle speed conversion settings in the adx editor, if so can anyone tell me what they should be. Thanks

is your BIN setup for a 4K PPM signal coming from the optical circuit?

**37chevrod** · 08-09-2013

In the Scalars list under Vehicle speed Sensor, its set at 4006.96 p/mile. is that what you meant ?

**RobertISaar** · 08-09-2013

yes, that covers the calculation portion. is the flag set to read an optical sensor?

**37chevrod** · 08-09-2013

is switch 18 bit 6 the one you mean, if so it was not set, I set it and tryed it but still no speedo.

**RobertISaar** · 08-09-2013

that's the correct one.

at least a communication issue is ruled out since the rest of the dash is working... can you post a XDL log and the ADX you're using? i'm wondering if there is something odd going on there.

**37chevrod** · 08-09-2013

I'll have to figure out how to post my xdl, hav'nt done that before.

**RobertISaar** · 08-09-2013

it's an accepted attachment, so you should be able to directly attach it.

When you reply look at bottom right for Go Advanced, then under that box is Add attachments.

Here's the adx and xdl file Ive been working with.

Vehicle speed output format is set to hex... change to floating point, it's in conversion tab.

**RobertISaar** · 08-10-2013

the equation is also odd.... should be just X, the * may mess with it. integer format will also work nicely, since there is no need for any decimal places unless you convert over to metric.
