Gery

Hello guys, i am Gery from Austria and i need help for my swap. I just swapped a 411 Pcm in my Vette. I used the 1998 and 2002 pinout plan for the Job.
I can`t connect the following wires to a new home:
Red connector 98: pin 24, pin41, pin42, pin46, pin69
Blue connector 98: pin 24

I doublecheck everything twice and fired it up.
It starts immediately but after around 10 seconds the engine stops to run.
I get the following fault Messages everytime: P1571, C1277
sometimes the DIC shows this too: U1064, U1016
The fuel gauge shows low but the tank is full.

Engine spec: 427 Ls3, 52Lbs Injectors, Killer Bee 2 Airfilter with Ls3 Maf , 102 Nick Williams TB, 102 Fast Intake, 180 Thermostat, LG 1 7/8 long Tube Headers with high flow Cats, Lingenfelter fuel pump, Dewitt Radiator

Maybe someone who did the same Job can help me?

This is typical for an ECM swap that has NOT had the "anti theft" system deleted
Have you turned off or disabled the VATS ??

Gery

No messages after Pcm to Bcm relearn mode.
Vats is deactivated.
I think it's problem wirh the program?

Most likely NOT an issue with the programming but a problem with the ECM being pinned correctly

Double check your pins. Mine is working as I did that last week. see my thread

I did have to disable some DTC. I'm playing around with fuel gauge trying out the express van parameter. I'm using hptuners.
