try 30 minute program to resync
try to start leave key on 10 minutes until theft light out then turn key off 7 seconds
repeat 3 times
works with blade key only

Did you make a 1:1 ECM clone?
What was the reason for replacing the ECM?
Does the odometer show dashes or mileage?
Read old ECMs and purchased ECMs and BCMs,upload here.

I have cloned lots of those with IOTERMINAL never had any problems..i never had any need to use sps, 100% clone and start no need to do anything else.. did you clone eeprom and flash?? I have some backups from a couple of E78 ecu in case you need...
Check all your fuses maybe missing 12volt backup on ecm . Provide vin and I can post wiring diagram if you need.
