Default Fuel wire issue/Causing trim issue? - 06-18-2021, 11:26 PM

Hello everyone so I'm running into some issue with my fuel trims and I wanna say its a problem i have with the fuel wires somewhere. Recently I've purchased the harness adapters off eBay for the o2 connections, i also purchased the fuel wire add on. I've installed both adapters and wires and ran some logs but my trims are pretty inconsistent from the middle of 3rd gear and on. ill attach a log with the fuel wires connected and one with wires connected but on map 0. I've been going at this for several hours and I'm lost at this point. NEEDING SOME HELP.

MAP2 user adjusment settings FF set to 50 DWP set to 0 and BIAS all the way down is set to 118

AFR's look fine but yes, trims have a bit of a delta.

Enable option bit 0 and see what affect that has. Maybe you have a bad fuel wire connection.

Not a fan of emissions override stuff...tends to cause issues.
