    Data Logging Help Request

    I have a 4.3L V6 (Vin W) with CPI. My ECU is 16168625 .bin is BBNT. I am using Tuner Pro RT with an Autoprom connected directly to the Memcal with a G1 adapter. I am using XDF "Advanced $E6 TP5 v250.xdf", and ADX "$E6 A201_E6_v250.adx". The engine runs but is very rich, idles about 800 RPM, and continues to run/lope after shutdown until I put it in gear and let out the clutch. 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 to sputter. The datalog shows 125 TAC, 12.2 Map, and 451 Spark Advance and temps are all -33. Also shows .5 Battery Voltage and 5 MPH when sitting still in shop.
    I tested each sensor with engine off and ignition in run to see if there was a problem. These are the results, let me know if they look out of specs: ECU Voltage in was 12.5, grounds are good.
    IAT 1432 Ohms @ 66F.
    CTS 1217 Ohms @66F.
    TPS Idle=.58V WOT=4.47V.
    MAP idle=4.79V (I think that's Bad) WOT=4.9V Ref=5.02V.
    O2 sensor signal= .185V
    Ignition Ref Hi=.15V, Ref Low=4.6 mv

    I also checked Ignition Control Module Bypass lead from the ECU and it had 33.8mv if that means anything, (I suspect it is running in bypass mode).

    Thanks for all the help I have already received with this project and thanks in advance for any help and wisdom you might be able to send my way.
