JB4 last safety

[Mike810]

Has anyone had the jb4 show the last safety of 2? I guess that is AFR lean. Terry said to reset the code and see how it does. I only have the jb4 and bms intakes. I run map 2 most of the time. Sorry for the large image. Just took a screenshot with my phone. What could cause this? When this code is there does that mean I am driving with reduced power on map2 or map 1?

Thanks

Thanks

If you have the fuel wires, not a very common issue, but it happened to me.

The connector on the end of the fuel wires that go to the O2 sensor, one of mine didn't actually go through the insulation on the O2 sensor wire, Drove like that for months getting that code and going into limp mode on the 3rd to 4th gear shift at wide open throttle. Finally checked those fuel wires and saw that one didn't actually connect properly. Just redid the connection and it went through the insulation and haven't had that problem since.

Just a thought. Good luck.

If you delete codes it will clear the last safety value back to 0, so you can see if its a current or historic issue.
