Irratic wideband...MALF codes inside (datamaster)

Okay My wideband is going rich lean etc off the map while cruising. during WOT it goes lean only at 100%TPS....if i go like 75% its around the 11ish range.

Now i got faults...

MALF 26- CPP electrical fault
Malf 96-4000RPM VSS circuit fault
Malf 83- TCC control feedback fault.


The tune is for my buddies 4l60e with a 3600 stall mine is 3000. Dont know if it matters.

Also the computer is 1995...my wiring was for a 1994 computer.

Thanks Jay

Also when deleting evap out of my tuner cat since i dont have any of that on my car, will this just get rid of the code? or will it take it out from the computer reading it?
