ECM , e85, cable driven 96 s10 with a lq4, 6.0, 2000 ecm - want to set up e85, for new combo, told that i need a different ecm for e85 and cable driven, problem is finding right ecm was told to look for 2004 ecm have no number to find this from car-parts.com
There is a whole thread in here just on this. If your not planning on running boost than there are several you can choose from. Any 2002-2004 5.3 Avalance,Tahoe, Silverado, Suburban will work. If you want to run 3 bar boost, then you need this:

ecm pcm on car-parts,com i see this number #12586243, and it listed them on tahoes, corvettes and s-10, but what about the hardware (Hwd) number don't understand where you getting this, they don't list that number and in one thing i read you said something about tahoe os, whats that about.
The ecm I have in my truck currently is a 2002 Tahoe 5.3 flex fuel. It is cable driven, but only has a 4l60E trans setup available and as far as boost goes, it only has a 2 bar enhancement available. I plan on swapping to a 80E and more boost than that, so I am swapping to the 2004 Express Van ecm. I will have to re pin my ecm from red/blue to blue/green, as well as the trans, but then I will have a 3 bar enhancement with flex fuel.
Apparently I have read, HP Tuners did in the past, apply a 80E segment swap to the 02 Tahoe, even though, the OS did not match. Again, I only read thsi. I have not asked them to do it, and I can not do it on my own, since there is no 80E segment on that OS readily available. I can look at my ecm and get the hdw # off of it if you want it.

As I said, "As far as I know", First time I have heard of it. I am glad to hear of it though. I am surprised as much as I am on HP Tuners forum, I have never heard of any one say anything about it. Thanks for the good info subeone!
