Just spitballing here, but I know there is code to run a MAF 7427 setup with TBI, thanks to Dimented. I know you can also mod the 7427 to make it drive 8 port fuel injectors, thanks to Haulin'A$$. I know there is a cool vortec style port fuel injection intake (ramjet), thanks to GMPP.

Now, how much work am I looking at in attempting to get all these systems together in one package?
I have the bin and xdf for the MAF 7427 setup, and I also have the bin and xdf for the port fuel 7427 setup. Unfortunately I have no idea how to mesh the two together to run an OBD-1 port fuel MAF setup.

Starting with a truck that originally had the 7747 TBI/700R4 setup.

The wiring and physical stuff isn't what primarily concerns me, it's getting the MAF and PFI together in the bin/xdf. I know I'm gonna need to mod my 700R4 to get it to work with the 7427, no big deal. Can anyone give me some pointers on the software side of the house??
Thanks guys

 

not even a "that's a dumb idea" or anything? wow.
o well

 

It WILL work, that is what I run. The TBI ECM will run the PFI in Batch Fire mode on the MAF. It takes some tweaking, but I got it to run very well.
