escalade 2002 6.0HO fuel flex conversion: no FF parameters like avalanche 2002

[sierra15]

Hi,
last time I convert my 2002 avalanche 5.3, easy, adding injectors and sensor, and just activate the FFV in the PCM.

now I try to do same with the 2002 escalade 6.0.
but it don't have any fuel flex possibility into the PCM...
I have the biggest injectors, the sensor. also a another pcm from a avalanche 2002 5.3
may be I can do something with all of this?


-the pcm of the 2002 5.3 have a cable trottle and the cadillac is wired.
-ECM are physically same, writed J1 BLUE near the blue plug (called P59)
-VATS will like another PCM/serial?
-can I program the 2002 avalancche OS with flex fuel into the cadillac2002 pcm?
-may be I'm not the first guy to do this, will I found a hpt tune ready to use?

thanks for helping

escalade2002 essence.hpt

here the hpt of my cars.

can i use the hpt found in the forum below directly in the escalade?

2005 escalade.hpt

I answer myself,

i take the 2005 escalade.hpt, the better os for fuel flex I think
change fuel parameters form a .hpt with 12613412 injectors. stock fuel rail with a pressure regulator connected to MAP mean a constant injector flow rate vs KPA VAC?
change timing from the stock .hpt
change airflow to stock .hpt
change the fuel flex parameter from avalanche fuel flex .hpt.
change the transmission and speedo etc parameter from the stock .hpt
activate the lean cruise mode
change the system option form gmt800 to V

on this, ecm and tcm can't be separate, i set all like stock parameters , two are 4l60 but some parameters are added like reverse solenoide and I don't know what is it.

Am I on thee right way?
