Question type: Maintenance & Repair

My 2000 Dodge  Durango  5.9  ltr  would  shut  down  when  driven about  3
miles  so I  swapped  out the  ECU  Computer  but  I  don't  drive  much  any  
more  when  my  tags  and registration  came  up  for  renewing  it required  a
smog  check  everything  passed but when  it came  to  the  Emissions  part it
came  back not ready  the smog tech told me to  get  on the  freeway  for about  
a  half  hour  then  bring  it  back  well I  put it  in  the  garage  and  forgot  about  
it  my wife  reminded me  that  I  had to get  the  tags and  I  went out  on the  
freeway  30 minutes  out  so that  I  had 1 hour round trip  I  took it  back the  
tech checked  the OBD And  still it came  back   NOT READY  is it  possible  that
the  computer  is  the  problem  and  I  should  swap it out  again  what  steps  
should  I  do  when  swapping  out  the  ECU  Computer  when  I  did  it  the  first  
time  I  disconnected  the  battery  completely  and  I  also  got  new  battery  
How much  driving  is required  after  a ECU  Computer  is swapped  out in
order for  all systems  come back  as passed or ready I've  tried  a cap load of  
sites asking this  Question  but  basically  it's the  same  thing  drive  more .
Is there  an average  amount  of  miles or time needed to do  it  or is it  different

unfortunately there isn't really a set time or distance to drive it will vary. usually the trip down the freeway will do it if its a daily driver and all EVAP systems have finished there testing, which takes multiple drive cycles, but in your case it sounds like it will take a bit of time im honestly surprised your abs light isn't on from replacing the ECU, normally when the ECU is changed it removes the abs programming (pinion and tire size) but i guess you somehow got lucky.
