Hey guys, I'm new to customization.
My English is not very good.....
I have a 1992 S-10 Blazer 4.3 TBI 4L60 MD8 which I am working on.....
The car went with ECM 16170871 AZSM * 86AZSMKB21750743 * but it costs EPROM AYURR
And there is another ECM 16144288 AZSM *86AZSMKB21713817* without EPROM.
Which ECM is better to leave on the car, what is their difference?
I'm looking for the original BCC AZSM.
