I am new to ECMLink, please go easy on me.

Showing rich (11:1) idle after SD install. Takes a few minutes to idle on its own without feathering throttle/getting it warmed up.

Wideband all over the place while cruising. I wired my wb into my rear02 for narrow band sim, wasn't sure if my front 02 is cycling normally or if I can use my wideband as a front 02? until i can get a replacement upstream 02 sensor.

Installed PTE 1000 injectors and made setting changes in FT's according to ecmtuning injector guide.

Any help is appreciated.

Your front o2 is not cycling.
Your ECU inputs tab doesn't make sense.

Why are you simulating narrowband? Where is your wideband wired up at?

What MAP sensor do you have and what IAT do you have? Did you get the plug and play harness or did you wire in manually?

If you have your wideband in the rear o2 spot and have your front o2 is your oxygen sensor then uncheck Enable narrowband simmulation.

In ECU inputs you need to assign where your MAP sensor is and IAT sensor is and then save pin assignments. Then in Pin Assignments for ECMLINK functions ECU Side you need to tell it where the Manifold Pressure(MAP) is at. Then tell it what type of map sensor you have.
If you are using your normal oxygen sensor in the front location then you don't need to simulate narrowband so leave as undefined.
