2020 mustang gt twin turbo cant get o2's to enable

[gaehrings14]

Hello everyone, this is my first post and I would like any input on this matter. I bought this car wrecked and redid the whole front frame and built a turbo kit from scratch from my car... I wanted to get into tuning my own car and i've been stopped by not getting any o2 readings.. I have checked wiring from where the car was crashed and verified everything was ok...

I have some extensions for the 02's from lethal performance, besides that my fuel system is still stock. I have the hpt file and the logging file

get rid of those extension they cause a lot of issues.. NGK makes O2's with longer connectors jut need to do a little research.

if your fueling trims/off target by alone it will not work/enable as well

Your o2 sensors are reading on your log. WB EQ RATIO 1 and WB EQ RATIO 2

This ford has wideband o2 sensors, they're reading fuel in lambda. Time to start learning about all that stuff bud. Judging by the log the fueling is way off

My guess is you added 30% larger injectors?

I haven't done any mods to the fuel system... I will take a look at that, i understand that Its in lambda... the car wont run not even getting into boost.. it was doing that even before I unlocked the computer.. if you give it any throttle just to get the car to move out of its way the car goes into limp mode and shows the wrench.. Im going to shop tomorrow.. I just thought that it would show up on the vcm scanner under the gauges so when it was showing nothing i was under the impression they werent working... I have a tuning background haltech, fueltech, megasquirt, holley but not with any factory ecu's.. and i don't see any books I can get for the 3rd gen.. just point me in the right direction and I will get a book to start reading.

Thanks for your input guys very much appreciated.

still with factory injectors.

Or it should have E85 as a fuel.

reload the changes and try again

it looks like you are still on stock MAF curve...this wont run right since your charge pipe is now 3.5"...
