I'm getting C28/C29 every time I ride the bike.
At this point, if I start it in neutral it often doesn't come on right away. Generally, it comes on as soon as I put it in gear (instantly, as soon as I click in). If not, it comes on within a block or so.
Relevant mods are PC3USB, TRE from 92westshady on SVRider, STVs removed and eliminator from D'Ecosse.
I've tried two different STV eliminator boards (first one of his handmade ones, then one of his production ones). When I initially put it on, it was fine - this happened slowly. For a while it would stay off if I fired the bike up once it was already warm, not now.
I recently replaced the wiring harness. I think this may have changed the symptoms a little bit - it used to not be 100% - but don't remember for sure.
Any recommendations on what to do (other than get rid of it and go back to stock intake configuration)? It's annoying having a CEL full time.
