Our LX's only require a water temp above 145 degrees for lean burn and of course no NOX purge cycles either.

If you haven't seen it yet .. And you are ok with the side effects .. you can disable the NOx purge cycles on the Gen1 Insight as well.

Under the P137 code all other functions including autostop work as intended.

You still have to have conditions that normally allow lean burn.
