I purchased a 04 gto ecm for my build . I have a 91 s10 5.3 4l80e I know lean cruise only works on 04s since it was a "holden". I have read and read and set my multiplier up in hp tuner for some reason it still won't go into lean cruise.(watching with WB) Here is what I did I pulled the stock 04 gto file off and flashed the file I had in my 04 express van PCM that was already set up for my 5.3/80e is that possibly why it won't enable? I thought the coding that told it that it was a holden was hard coding.

There are several parameters that have to be set for LC including enable speed, etc. Here's a link

I populated all the tables like shown on that post but still won't go into lean cruise I'm not sure what I'm missing.

Make sure you're in Closed Loop. Its required for LC.

Why don't you post up your tune and then we can see where it's different. Much better than guessing. BTW I run mine in complete open loop and it works fine.
