No BLM Count on 1227165 ECU ?? / $32 Mask

Hey Guys, I have a 1227165 ECU, $32 mask, with no BLM count. I have done 2 datalogs, with nothing showing on either. Have no issues at all with the hookup of the Moates Gear, and Tunerpro Rt V5 finds the hardware instantly, I have not had any issues of the ECU clamming up either. The unit is going into closed loop, but I also don,t see any variations in voltage at all on the O2. Is the ECU possibly dead, it has sat for most of the winter months without any power at all. Is it possible the Datalog file for $32 just does not see it. Thanx for any input! The truck does haul serious butt..........the ECU is from 1987, though. MrStude.

no o2 voltage variations but it goes into closed loop? blm not showing up? the BLM always has a value of some kind regardless of whether you're in closed loop or whatever; but just because it's in closed loop doesn't mean it's updating the BLM cell. the o2s always have voltage too. it's gotta be your adx. try a different one

Thanx Steveo, I appreciate the reply, It does seem weird, do you have any suggestions, for another adx file. I did check for O2 voltage, when I updated to the heated O2. MrStude.
