Ya I'm REALLY wanting them to add relative compression also

Next month, we will release new version to fulfill this function.

   My updates on DS 708 expired back in August of 2014 after one year. I still have the factory logos and the last Ford I tried on Power Balance  still worked ok ," knock on wood". I don't see cars too often less than 4 years old wrenching from home anyway , so no pressure to update for me so far.
     I still have to pull the old Snap On  MT2500 out a few times on older OBD II cars and try it where the DS lets me down at times but overall  708 still works good , I now have an auxillary battery power supply , and a spare backup 16GB  card of software in the event the other becomes corrupted. I was able to successfully add a key to an Acura RL last year for someone, I want to try and program and add a keys for customers of  other makes of cars  but reading of  hit or miss success , or lost function with newer update. I definitely be afraid to erase the existing keys and risk the car not starting with any keys if the function did not function .
   I was really thinking of  selling my DS 708 and upgrading to a  faster more modern Maxi Sys platform, but there has been a lot complaints lately about lost  functions on newer  software updates.
    Also on a Maxi Sys unlike a DS 708 if there is a  issue of manufacturer software functions on a new update lost or screwed up, it's  on the internal drive, you can't just power down and swap out latest software with a backup SD card made at an earlier date with  older software versions on it. There are no simple clear cut , fail proof instructions I have seen posted on how to make a working backup of earlier software version or archive older versions of software available to download in the event the latest update is messed up.
  I 'm  waiting till I really need to update my  new car coverage , rather than update it , it may be more cost effective to just sell my existing 708 for $400 or $500 , get another  one for $999 with a super saver coupon at Harbor Freight , make a back up of the SD card as shipped. If the software shipped with is not too dated, just  use the thing as is for 6 months  to a year before I decide to register it and update  the software on it.
