Having strange fuel problem. Truck runs fine but then all of the sudden the WBO2 will peg at 22.3 and all power is gone. It does not shut off. It is almost like the computer burps or hangs for a bit. Check rows 580-743 for example of a “burp”. Strange things are happening. It comes back for a few seconds from 744-757, and then goes weird again from 758-890. It continues to cycle back and forth from running just fine to having some sort of fueling problem.
You will have to export the XDL file to csv. I would have uploaded the file but it is too big.
Truck is 1993 K1500 TBI with vortec heads. Base for tuning was by reading the stock BIN. 16168625 BBMC $E6. Tuning with WBO2 and following Dave's spreadsheet found here.
Any insight is appreciated.
