I have a 2004 GMC Sierra with the LM7 5.3
I'm taking a trip next week and would like to throw on lean cruise.
I don't have a wideband or anything, still need to get one.
Just looking for some insight as to how I would go about this.
Thanks guys.

I dont believe you can run the LC patch on 03-08 LS1 PCMs as they are 1MB flash vs 512kb.
I may be wrong, but Ive only heard of 98 (with 99+ PCM conversion)-02 cars/trucks using LC.

I have a 1mb pcm running lean cruise... if you have the tables then it is in there. Just download the patch to enable those tables

1997 Saturn sc2 turbo, tuned with megasquirt on e85
2000 s-10 turbo'd tuned with efilive on e85
Really?! Thats great news, I didnt know 03-08 PCMs had the .cax to enable LC!

I honestly don't know what I need to be looking for.

You would have to know the byte address/offset inside the binary file for parameters you want, and you have to know the format of the parameter data (bit width, signed/unsigned, little/big endian, scaling)...
i.e. you would have to reverse engineer them for your calibration.
So, I'm assuming it's going to be a fairly difficult process to get it going?

Alrighty, well I found the LC patch and enabled it.
Going to try out the LC tables from a stock 04 Monaro tune.
See if it helps me out any.
Not quiet certain if I want to run the lean cruise yet on my trip next week. Kinda worried about running it that long lean without a wideband
