Hey guys!

I have a weird situation that I'll have to come back to tomorrow. I am not sure if it is an ECM or Smartra problem... (and even tho I do a lot of them, I still didn't really get how they engineered their smartra in those years... no eeprom in smartra module, but it is not just an antenna amplifier, it really have immo info stored... but where??? if someone have deep understanding of those system on these old shitbox, feel free to share!!)

long story short, right now smartra gives no more data and don't accept key programming or smartra neutral mode... after only a basic ecm neutral procedure. (following P1690 hyundai diagnostic procedure)
I would like to have a second option if think go south again tomorrow...
can someone immo OFF this ECM for me?

2009 Hyundai Accent, 1.6L gasoline, manual transmission... ECM is labeled as Kefico, but it is Bosch hardware.
Bosch M7.9.8
Kefico 9001040062KF
GMC-9N6CFS4-5000
39131-26BE2

internal flash is from ST10F275
eeprom is 95160

thanks x100000 for the help!

I ordered a used ECM, and smartra data and programming function came back to life... but when I put the ecm neutral, again same symptom of no data and programming function available in smartra...
I find a website who could immo off that original file right away for a decent fee, so I went that route. car starts now. thanks anyways guys!!!
