I pulled the magic metal box out of my car to find out what type of ECM I have and I can't find any numbers on the case or on the chip that relate to the ones in the tech article.

I am pretty sure that it is a 1226870 but I can't find any numbers to back this up.

Thanks in advance!

Well, I guess I have the 1227302 chip.

Is this chip worth programming for the novice??

I noticed TunerCat does not support this chip and I have not found any others that do either.

Thanks for the help!
