Here's today's story:

Installed Innovate LC-1 and DynoTune gauge (in place of the clock along the line of this discussion: https://www.rx7club.com/showthread.p...+idiot+cluster).

Also, have LTX12 (installed by someone else) around which I've been chasing out bugs. Right now, I'd like to get the LTX logging software to include AFR along with the other parameters. Would someone here help me understand how these three units would be interfaced properly?

Reading the MicroTech Injection diagram, there is an O2 sensor input that is connected directly to an O2 sensor. So, do I just connect the Analog 2 output from the LC-1 there, and the Analog1 output to the DynoTune?

I connected Analog 2 to the stock O2 connector under the hood expecting that the original ECU installer had modified the harness so that this would go to the new ECU (going to trace wiring to verify that today). That done, the log shows the AFR at 19.9 and it never changes, which suggests to me that the ECU isn't getting a useful signal.

Thoughts or suggestions?


Thanks!

your ecu does not ave the correct software for wideband logging. you need to send it back to microtech to have it re-calibrated.
