730 repin to run Boost...??? - Third Generation F-Body Message Boards

I have a 730 and want to repin to run boost...
The "tech" article here says 749 swap... No, I'm not swapping in a 749, I want to repin my 730 and run code59 for boost.. so that wiring / repin does not apply....

I've got a few other answers from people...
Which one???
================
Actually the ONLY 2 things I repinned where I swapped C11 & C12 (injectors I believe) and one injector ground. Thats it. I didn't mess with the IAC that alot of people say you have to repin. As far as your VSS, leave that alone, your shift light doesn't work with $59 code I believe. Running anyother code like the $58 or $59 (my vote is for the 59) you'll need another MAP sensor as well.
==============
I don't think Anesthes realizes you are using a 730 ECM with the AUJP MEMCAL and $58 code in it. He is talking about wiring an actual 749 ECM for saturated injectors using a Sy/Ty schematic. Your 730 ECM doesn't have the second injector driver he is talking about hooking wires to.

Anyway, leave the IAC wiring and the injector wiring as stock 730 ECM.

Only change the following if you need to:
C1 connect to B12 (VSS for cruise)
F1 connect to F4 (shift light) for manual trans
F2 connect to disconnect (AIR pump solenoid)
F6 connect to F4 (TCC) for automatic trans

EDIT: You are NOT doing a 730 ECM to 749 ECM swap. You are doing a 730 ECM re-pin to $58 code. This is why you need to leave the injector wiring as stock 730 ECM. The IAC not needing any pins moved stands for both the 749 and 730 ECM.
===================
Correct, just swap c11 and c12 then i believe you move d6 to c13, that's it 3 wires. Go
with the $59 code, you'll need a 3 bar map sensor.
