No codes. I just went back out to retry. Now the LM-2 is working perfect. It my R4 controller that keeps saying can not connect to ECU.
The LM 2 is fun though. Way more info than a scangauge and you can calibrate your Throttle position sensor among other things.
My AFR is around 13.6 at idle, and between 12.7 & 14.6 during driving normal. Not sure why the fluctuation (Need to study that). The LM 2 even shows my open loop, short term, and long term fuel trims. Which are all used to tune the URD
If I could just figure why the R4 controller cant connect I would be tuning away
