Need Help Data logging GM 4.3 CPI I gets wonky numbers. Could the PCM be bad?

[4.3JeepYJ]

The engine runs but is very rich. When I start the datalog it shows odd numbers that don't change even when I increase the RPM at WOT it gets to about 3000 RPM and starts sputtering.
The datalog shows
125 TAC
12.2 Map
451 Spark Advance
temps are all -33
.5 Battery Voltage (Battery is fully charged)
5 MPH (when sitting still in shop)


I have a 4.3L V6 (Vin W) with CPI.
PCM:16168625
.bin is BBNT.
XDF "Advanced $E6 TP5 v250.xdf”
ADX "$E6 A201_E6_v250.adx”
using Tuner Pro RT with an Autoprom connected directly to the Memcal with a G1 adapter.

If the data seems to be non sensible, possibly you have the wrong adx. Try $0D

Thanks Ill give that a try.

Wait a minute...are you trying to emulate with Autoprom? I mean if the Autoprom is connected to the Memcal than that's the only way to get it to run other wise you would be running off the limp home mode which from what I've experienced, you'd get no/wonky data on the dash. Once in LHM, only way to get it out of it was to disconnect battery and start all over.

With that said, you should be able to identify which mask the bin is using which should coincide with which xdf and adx to use. Also you should look into disabling the "checksum" if you're going to be emulating and making on the fly changes.

I suspected it was running in limp mode. How do I identify which mask the bin is using?

[stew86MCSS396]

There should be a MaskID scalar in TunerPro. See if it's $0D $0E $31 then use corresponding xdf and adx. If you're trying to emulate read up on disabling the checksum.
