Wideband Direct serial tester wanted(ZE, TE, Aem, FJO, PLX)

very weird... it must be a problem with older version. looks like it doesn't get bytes if you look at the trace.

Did some logging and checking with both the in car display and the TE logging software. Both were perfectly in sync and showing 14.2 AFR. Then I connected the ECU logging cable and started eCtune. Started the logging with serial WB set to TechEdge... AFR showing in eCtune was 11.0 AFR Then I switched to analog WB logging via D14 (normal O2 input) and AFR values were back to what I was used to... 14.2 AFR. Did another check on serial WB in eCtune.... still the same... 11.0 AFR Then serial with TE software.... 14.2 AFR But then.... battery of the laptop was empty Tomorrow is another day. Should I do something else then only enable Serial Wideband Input for Tech-Edge?

what is the frame format you select in TEWBLOG? Can you try with frame format 2?

TE user make test again. Please 2a0 version. redownload http://websrv.ectune.com/wb_test.rar

some advice for the testers... Dont try firts if the software from the manufacturer works before you want to connect the wideband with eCtune! I have seen more than once that if you have used the com port with some other program, the port stays busy after you stopping this connection. Then trying to connect it to eCtune wont work because of that open connection. For example, if you use logworks from innovate before connecting the wideband with eCtune it wont work. Sometimes you have to restart the laptop before you can connect the port again with another program. shitty windows software.......

Still 10.00 AFR on the screen, but far more usefull info in the trace file. I'm looking for a tool to 'record' the raw serial data from the TE port. Would that raw data help you CJ?

After a busy weekend..... Here a link and an attachment with a TE 2A0 serial dump. Logging docs: http://wbo2.com/sw/logger.htm#20frame -=-=-=-=-=-=-=-=- Forget the serial dumb that used to be here. It was corrupt for some reason.

I don't trust this log. It shows E2 at every even byte.

It's official.... the log I made with portmon is BAD!!! I now made one withRS232 Datalogger (Eltima) and that one looks WAY better. It even is a replayable file, so you don't need a real TE

Bytes 6 and 7 are the bytes you need for AFR. In my case it represents the voltage(!) on the WBlin output. With 00 00 beeing 0 volts and 0F FF beeing 5 volts. The default formula: AFR = (V * 2) + 9 Sample frame: 5A A5 6D 10 77 08 90 0F 62 03 00 01 38 00 C0 00 01 00 01 00 01 02 AE 00 00 03 00 51 5A A5 are the start bytes 6D is a counter 10 77 is a time ticker 08 90 is for AFR 0F 62 is for Pump Current 08 90 Hex is 2192 decimal. 2192 is 2.676 volt ( (5.00 / 4095 ) * 2192 = 2.676) 2.676 is 14.3:1 AFR ( (2.676 * 2) + 9 = 14.3) Does this help?
