Narrative:
We were assigned and briefed the SOLDO2 RNAV departure from runway 17R in dfw. The captain performed the takeoff from runway 17R. Upon request I retracted the landing gear; and selected 'navigation' on the FGC. Upon reaching acceleration altitude; I began the climb flow when it came to my attention that our intended course was to the right rather than centered. I crosschecked the captain's CDI and noted that his was also to the right and he was correcting towards it. I was finishing the climb checklist when departure control called and inquired what our heading was and informed us that we were nearly 1 mi off course. I responded that both FMS units showed us less than 1/10 mi off course and that they both reflected the same thing. We were then assigned a left turn direct to soldo intersection and continued the flight without incident. We were given a phone number for the controling agency and contacted them upon arrival. While en route; the captain and I were discussing what could have happened when it came to our attention that both FMS units had been programmed with the SOLDO2 departure off of runway 18R. The controller and the captain discussed the incident and we were told that there was never a loss of separation. Regarding runway 18R and 17R; all waypoints for the SOLDO2 departure are the same. The only difference being between 1100 ft and 1080 ft respectively; and trexx intersection. Without going to the FMS departure page and verifying the runway; the departure appears correct while xchking the waypoints on each pilot's mfd which is what happened to us. What's more misleading is that while into position and hold on runway 17R both CDI's showed centered even though runway 18R was the runway programmed. This is one of many software problems that have resulted from trying to couple universal FMS units with honeywell avionics. More information needs to be readily presented indicating the runway and departure programmed is correct or incorrect.

Title: E145 FLT CREW HAS TRACK DEV ON SOLDO RNAV SID FROM DFW WHEN BOTH FMS'S ARE PROGRAMMED FOR RWY 18R VICE RWY 17R AS USED.
Narrative: WE WERE ASSIGNED AND BRIEFED THE SOLDO2 RNAV DEP FROM RWY 17R IN DFW. THE CAPT PERFORMED THE TKOF FROM RWY 17R. UPON REQUEST I RETRACTED THE LNDG GEAR; AND SELECTED 'NAV' ON THE FGC. UPON REACHING ACCELERATION ALT; I BEGAN THE CLB FLOW WHEN IT CAME TO MY ATTN THAT OUR INTENDED COURSE WAS TO THE R RATHER THAN CTRED. I XCHKED THE CAPT'S CDI AND NOTED THAT HIS WAS ALSO TO THE R AND HE WAS CORRECTING TOWARDS IT. I WAS FINISHING THE CLB CHKLIST WHEN DEP CTL CALLED AND INQUIRED WHAT OUR HDG WAS AND INFORMED US THAT WE WERE NEARLY 1 MI OFF COURSE. I RESPONDED THAT BOTH FMS UNITS SHOWED US LESS THAN 1/10 MI OFF COURSE AND THAT THEY BOTH REFLECTED THE SAME THING. WE WERE THEN ASSIGNED A L TURN DIRECT TO SOLDO INTXN AND CONTINUED THE FLT WITHOUT INCIDENT. WE WERE GIVEN A PHONE NUMBER FOR THE CTLING AGENCY AND CONTACTED THEM UPON ARR. WHILE ENRTE; THE CAPT AND I WERE DISCUSSING WHAT COULD HAVE HAPPENED WHEN IT CAME TO OUR ATTN THAT BOTH FMS UNITS HAD BEEN PROGRAMMED WITH THE SOLDO2 DEP OFF OF RWY 18R. THE CTLR AND THE CAPT DISCUSSED THE INCIDENT AND WE WERE TOLD THAT THERE WAS NEVER A LOSS OF SEPARATION. REGARDING RWY 18R AND 17R; ALL WAYPOINTS FOR THE SOLDO2 DEP ARE THE SAME. THE ONLY DIFFERENCE BEING BTWN 1100 FT AND 1080 FT RESPECTIVELY; AND TREXX INTXN. WITHOUT GOING TO THE FMS DEP PAGE AND VERIFYING THE RWY; THE DEP APPEARS CORRECT WHILE XCHKING THE WAYPOINTS ON EACH PLT'S MFD WHICH IS WHAT HAPPENED TO US. WHAT'S MORE MISLEADING IS THAT WHILE INTO POS AND HOLD ON RWY 17R BOTH CDI'S SHOWED CTRED EVEN THOUGH RWY 18R WAS THE RWY PROGRAMMED. THIS IS ONE OF MANY SOFTWARE PROBS THAT HAVE RESULTED FROM TRYING TO COUPLE UNIVERSAL FMS UNITS WITH HONEYWELL AVIONICS. MORE INFO NEEDS TO BE READILY PRESENTED INDICATING THE RWY AND DEP PROGRAMMED IS CORRECT OR INCORRECT.
