7747 to 7427 PCM swap question's
I have a 350 tbi with cam, vortec heads, roller rockers, and 670 holley tbi. It runs like crap because the cam is too much for the ecm to handle. So i want to swich over to the 7427 pcm with maf. My first question is: Could someone post the latest version of the maf code here? I have a 700-r4. I want to tune it with tuner pro RT, can i do that? How do i go about reading and burning to the chip? do i need a programmer?
I'm new to programming, so give me a break. After getting the stuff to burn with, do i just upload the maf code and thats it? Thanks for the help everyone

FWIW, a person starting to tune..I would go with the EBL Flash. You could buy the MAF, duct work, PCM, 93-95 Knock sensor, Memcal Adapter, Flash Chips, Prom burner, etc. All of that will cost you close to what the EBL will.

I heard some bad things about the EBL, so i wanted to do the maf pcm setup. I've already got the ocm and knock sensor and maf with duct work, I just wanted to know mainly if i can flash the pcm's chip or do i need a burner/reader?

I dont know what bad things you have herd about the EBL?? Its a great system and its plug and play for your ecm. It wont control electronic trannies but you dont have to worry about that.
