Flex fuel on 02 escalade

[RawrMotorsports]

Is there a writeup or sticky ? Or could someone walk me through how to add flex fuel to a 02 escalade 6.0 ? I need the 02 tahoe flex file and the sensor I got that part what else ? How do I wire the flex sensor in ? Po1 ecu , how do I change the Vin on the new tahoe flex file ? What else am I missing ? Thanks alot !!

You will have to segment swap the flex fuel file into your file. Just swap the engine and engine diag segments.

Ok thanks that makes more sense .. can anyone help with what pins the sensor needs to be wired into the po1 ecu ? I can repin just need to know what # pins and also what pins are usable ECU grounds I need to wire my wideband o2 into ecu ground while I'm at it thanks

I tried to do a segment swap it wouldn't let me is grayed out because of different OS from what I've gathered .. thinking about using the tahoe flex tune and just changing the vin with vin wizard then copy all my stuff over .. would this work ? 2002 po1 ecu

Unless something has changed, HPT won't let you create a VIN/OS mismatch. There are other products out there that will. Once the VIN/OS mismatch is created HPT will let you license it though.

It let me create It I haven't licensed it or copied all my tables over yet but it's a 02 flex tune with my vin now

That typically breaks their licensing scheme.

I thought that only mattered if the year code of the VIN didn't fall within years covered by the OS.
