03 Evo 8, Stock Ecu ,
This is the gauge I have: https://ktperformance.net/i-7443459-...298e7dedc230f2

I have tried everything I can find anywhere to try and get this gauge logging to EvoScan with no luck. I see that some people seem to have got it to log this gauge but no matter what I do it keeps showing COM port closed over and over when I try to log.
I have the correct serial cable, my brand new laptop I purchased just for the Evo is recognizing the cable but keeps showing COM port closed I have tried every different option for WBO2 at the top. COM port is set to 3 on cable and EvoScan.
I know the listed options are for AEM, ZTX and Innovate but I thought it would still work with my digital Autometer Cobalt WBO2.
I have read through every thread I can find but none are using this exact gauge. Ive tried changing all the values, baud rates, etc.

Has anyone successfully logged with this gauge or have any useful information to help me get this going?
Any help would be greatly appreciated.

 

If you can't get it to log over serial, you can wire up the analog output into one of the ECU ADC inputs and log it through a mut request. Pretty much everyone that does this uses the rear 02 sensor ecu input and deletes the sensor. The downside of this is it is slower than serial and also slows down your other mut requests.

 

Thanks, I have read about tapping into the rear O2 ecu wire with the signal wire from gauge and changing the formula to get an accurate reading but I am no math whiz and that seems like another nightmare to try and get the formula correct. If all else fails I will have to go that route though.

I would really like to get this working as I have now invested two cables and a serious headache trying to figure this out.I have went over everything and just now took all my console and lower dash back apart to trace all wiring and everything is wired the way it is supposed to be.

 

does autometer have its own logging software you can test with? That way you can maybe isolate this problem to being an evoscan issue or a hardware issue.

 

I cannot find any Autometer specific logging programs or software they produce, that was a good idea though. I have retraced re ran every wire, made a new common ground etc.
At this point I believe it either has to be an issue with the specific cable I have not working correctly as I have seen lots have problems with cables, or I have yet to find anyone that has successfully logged this gauge on EvoScan so it could be that the gauge is not cooperating with EvoScan and the Wideband settings there that are labeled and designed for AEM UEGO and Innovate.
Looking at the diagram for the gauge I have: https://www.autometer.com/media/manual/2650-1143.pdf it only shows a diagram of it being wired to a standalone datalogger. Its hard to interpret what you should do with the Blue/Black wire from the gauge as it says it is an optional ground and has it routed to the same spot as blue signal wire.
I have tried it ran as just a ground with the ground from the gauge and cable and tried running it together with the signal wire and neither work.
