 Your only solution in this case is to either (1) get a working MFI relay set up back in the car (preferred) or (2) always go into **Direct Access** and make some trivial change to a setting there and hit **Save to ECU** before you turn the ignition key off. Your only solution in this case is to either (1) get a working MFI relay set up back in the car (preferred) or (2) always go into **Direct Access** and make some trivial change to a setting there and hit **Save to ECU** before you turn the ignition key off.

 But unless you do that, ECMLink will just show you what you last saved...not what's really inside the ECU.  So that can definitely add to the confusion. But unless you do that, ECMLink will just show you what you last saved...not what's really inside the ECU.  So that can definitely add to the confusion.
  
-By far, the BEST way to solve this problem is to replace the battery with one that is capable of sustaining sufficient voltage to the ECU while cranking. ​ But if that's not possible, you can always go into **Direct Access** and make some trivial change to a setting there and hit **Save to ECU** before you attempt to start the engine. ​ That will force the current **ECU Config** settings to flash so that even if the ECU resets, it will just start back up with your recent changes from flash.+By far, the BEST way to solve this problem is to replace the battery with one that is capable of sustaining sufficient voltage to the ECU while cranking.  ​Check for corroded terminals or ground connections as well.

 +Another option would be to make your ECU Config changes, turn off the ignition, wait for the MFI relay to click (6-10 seconds later) and then turn the ignition key back on and crank as normal.

 +And one final work around would be to simply leave the engine running. ​ As long as you don't have to restart the engine, the settings can't get dropped. ​ When you do turn off the ignition, though, make sure to wait at least 6-10 seconds for the MFI relay to click off before attempting to start the engine. 
 + 
 +Obviously these work arounds are only needed if you have this battery reset issue. ​ As long as battery voltage is maintained to the ECU while cranking, then you don't need to do any of these things. ​ Settings will just work naturally then.
