1g dsmlink v3 sd set up when I turn the car off it erases the sd tune it removes all of the sd stuff and goes back to my stock maf set up down to the injector set basically everything I changed since I went to speed density gets erased when I turn it off all the stuff that I changed before I swap to speed density stays saved on the ecu
 
My car is a track car and doesnt have a mpi relay I rewired the car with out it do I really have to have it ?
 
Yes, or choose option 2 below:

v3settingsreverttodefaults [ECMTuning - wiki]

Hardwired Power (missing MFI relay)

Some cars (very few, but some) do not have a working MFI relay. Either the owner didn't want an MFI relay in the circuit (typically in a race-only setup where all the wiring was completely redone from ground up) or the MFI relay stopped working in someone's car and instead of replacing the MFI relay, they simply wired around it so that the ECU is immediately shut down when the ignition key goes off.

In either of those two cases, the ECMLink code does not have a chance to save your RAM-based settings to flash after you turn the ignition key off. So the settings are never stored to permanent memory and are lost when the ECU losses battery power.

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.
