CAT heating fuel map

Post by shadownat »

My fit doesn't have its cats anymore, should I change the cat heating fuel map to the same as the WOT fuel map? Also what exactly are the cell values in that map mean. Is it percent fuel or is it a target afr? Thanks.

Target AFR, as you'll notice AFR.CMD in logging should pretty closely follow these maps.

Bringing them to the same value can sometimes cause no open loop and other side effects so be aware when testing.
