Hi Alex,

Yes sorry the output from the LM-1 is currently earthed to the chassis. However it was earthed into the dta sensor ground initially.

Most likely that's your problem.
The ECU is directly to the battery, and the LM-1 is to the chassis.
Ground them to the same place, and they should read closer.
Probably too late now, but you would ideally ground the LM-1 by splicing the ECU power ground to ensure no ground offsets.
