?s about EFI conversion using GM ECM

[peter paul fenske]

Hi Adam

Lots of jcars junk yard full of em
but if you got the money buy a harness.
Yep a V8 will work
You will have to move the serial data pin 
prob one pin over on the A connector if using J car call. If you
use the 3.1 cam cal you won't


If you gnd the PN input to the ecm you don't need VSS
cannister and port air won't work, and egr won't work
and won't be tested.

Oh course it is as TBK says sometimes nicer to run
the whole schebang.
