Has anyone running the the idp ficm tuner had the error code E-2b occur? Ive had this code every time I've tried to load the tune (probably 15 times) with no luck. Idp said it is a voltage code so i had the batteries altenator starter and ficm tested and all tested fine. Only weak link was a voltage reg which i replaced with a new oem piece along with a new oem alternator. Idk what else to check? Anybody have any ideas? Any and all help is appreciated. Also idp said to update the programmer and when i tried this the program said the tuner is up to date.
