Apparently the gearhead-efi OBD1 library does not have definition $41 for the 1227746 ECM.
Perhaps converting to a different ECM like the 1227747 is an option?
Perhap$ purchasing the $41 definition file from TunerCats is an option? http://www.tunercat.com

'85 Caballero had ECM 1226868 and a 1227747 was pin for pin swap.
thank you everyone for replying!
Is the zip file tnr_setup.exe?
If so, that's the TunerCats setup file. Go ahead and "run" the tnr_setup.exe

Were you able to figure out how to use TunerCats?
TunerCats is very similar to TunerPro, except there is a cost associated with TunerCats.
TunerCats OBD1 software is $69.95, then a there is the additional cost of a TunerCats definition file of $19.95.
Unfortunately, some definition files are not available or have not be developed due to insufficient interest or popularity for TunerPro. Likely $41 has NOT been developed for TunerPro and likely never will.
