Hemi ECU / PCM Confusion Questions

I'd REALLY like to know where you are getting running useable hemis for a hundred bucks!!!!

I think the main issues are: If you don't have the original trans, and if you have the security whatever in the ignition. There are folks who can reflash these computers. So if you are using a "non computer" transmission, you want either a stick shift PCM or have it reflashed thus
