[Diy_efi] 96-97 vortec swap

[Karl Walter]

Hello,

I am planning to swap a 1997 Vortec 5.7 with a obdII 16229684 Computer
into an old Suburban.  I'm looking for possible ways to get around the
Evap system OBD II tests in the drive cycle.  Here is what I have so far:

install a evap pump.  I'd rather not.

Reprogram the ECU, This would be no problem if it was a '747, but I have
no experiance with the newer ecu's

Get a '94 ECU.  Will it plug in?  how much wiring changes? cost?

Swap the whole thing to a '730 ecu.  Anybody run a vortec system with the
old ecu?

Also, what other drive cycle tests that will throw a code am I forgetting
besides Catalyst o2 sensors, EVAP, and ?
