Haltech + 4AGZE

this is gonna be long but here goes...
i bought a smashed sprinter about half a year ago with a 4agze and haltech E6A computer. although there was front end damage the motor was fine. when i got the car home it would not idle it had to be reved abouve 2000rpm so as not to stall but above those revs it seemed fine.
last week i finally finished transplanting the motor into another sprinter and the motor idled fine and seemed to run great. because the computer had been disconnected for such a long time i assumed it had lost its memory and was running on base settings alone. the fact that the tacho also would not go past 2000rpm also made me think the computer had been reset back to factory settings and wasnt recognising the dual coil packs.
this mourning i brough in my laptop along with a disc of about 10 haltech map files with i got when i received the car. my theory was, put the last modified file into the haltech and it would be setup the way the previous owner had the car running.
now heres the bad part: i put into the haltech the most recent maps and the car would not idle below 2000rpm just like when i first got the car. i tried most of the maps i had on disc, all of with fouled the plugs and needed to be recleaned before trying each map.
so when i first ran the car, was i actually on base settings or was that the last programed map in the computer? how could the car possibly run fine after installation but not when it was in the old car, remembering it was still intact in every way? i reloaded the base setings into the haltech and it wouldnt even start, so the maps first in the haltech must not have been the base settings but a proper map, but why then isnt it on the disc of maps the previous owner gave me and why did the motor do the same thing it did in the old car when i put in the most recently modified maps?
i know this is very long and complicated but im desperate and need some help, possibly someone with experience with haltechs or other engine management. im stumped because all the fuel and ignition maps seem fine, plus it is definately set up correctly ie the haltech is programmed for 4cyl, dual ignition coil, 3 bar map sensor etc...
