I think something has gotten corrupted maybe something the ECU is seeing when its running. I don't know. I flashed the old tune back in after I started seeing the fueling problem. It is doing the same thing and now limiting fuel. My old data log files clearly show full fueling. I'm stumped.
Still no luck getting full fueling. Does anyone have a stock 11352409 48re Auto OS someone is willing to share. Searching this issue has led me to others having this similar problem with with some 602 OS's and auto trans. I have found 409 manuals but no autos. Thanks in advance for the help.
Could you send them to nm2769@gmail.com

409 OS solved my issue. Thanks guys for the input and support.
Could you email me or message me those slides pertaining to fueling/timing states? I'll happily pay for them if necessary. Having my own issues with defueling
