Standalone odometer wanted

**ACCLR8N** · 09-23-2009, 08:57 PM

Plenty of options for displaying live data, but not permanent mileage. Anybody come across a standalone odometer that is not part of a speedometer? My '95 OBD1 GM PCM doesn't store the mileage.

Odometer is not a legislated PID and is manufacturer specific. You would have to do a lot of data sifting or begging to be able to read it.

I'm looking for a standalone gauge that would be connected to the VSS to supplement my PC dash project. Something like the LED built into my '04 Wrangler's cluster.

Have you looked at ScanGauge?

I'm OBD1. I don't think my PCM contains mileage data. At least it hasn't shown up on any of the scanners I've tried.

As Aberk has pointed out, it's not part of the standard OBDII either. You can integrate data from the VSS over time and get a fairly accurate result.

This is the closest I've found so far to what I'm looking for. Don't know how big it is yet or if it has a trip function.

I gave up on pulling the data from the OBD port and going the Fusion Brain route. I can do much more with it for gauges: Oil/Fuel pressure, turn signals, fuel level, low coolant...and design my own graphics. It won't store data though.

Actually, this is exactly what I was looking for. Now I can go back to my dash design.

ACCLR8N, did you was able to make it work.
I'm in the same boat, I need to keep track of the mile, the PC can handle everything except that.
I know I have 24000 pulse per mile , ecotec 2.2 but cna't find a frequency divider or similar to adjust the odometer, these can go to one pulse=1/10 of mile .

As right now it's the only hold up.

No, I haven't. My wife got me the T45A2 module for Christmas from West Florida Components, but turned out to be some other random ENM module. They have my money and the part back since Jan. 19. I have nothing. Won't reply to my e-mails.

I do have my Fusion Brain pulsing an output every tenth of a mile to trigger the module. Every 60 ms it checks the speed and calculates the distance. During hard acceleration there will be a 5-8% error, cruising none. I have not tested this over extended periods of time. I just need to order the correct module direct from ENM and hook it up (in theory).

I've only found frequency dividers in 2, 4 or 8. I can't get an acceptable ratio and its not tuneable. Another option is magnetic pick-up and playing with the number trigger magnets and divider modules.
