elm327 bluetooth scan help!
It will connect via Bluetooth but cannot connect to the ecm of my 1999 trans am.
I've tried the auto scan for protocol as well as the SAE J1850 jpw.
Anyone ever have this issue? I got it linked to my 2013 dodge dart immediately but been trying the TA nonstop and always said it can't talk to the ECM.
THANKS FOR ANY IDEAS.
I've talked to the company and they have sent out a new one for free. Ill update if this one works or not.
I was just curious of theres a certain protocol that's is used for the ls1 or possibly when I had my mail order tune he locked my ecm?
Thanks for the ideas ya'll
