E38 cloning

[hijole1983]

Hello fellow PCMHackers,

First off I am new to the forum and new to PCM hacking. So 2 months ago my dad in Texas contacted me that my 2008 Chevrolet Silverado 5.3 ecu (that has AFM/DOD delete) took a crap. I’m military stationed overseas. He’s a recently retired mechanic that worked at a dealership and thus doesn’t have all the fancy dealership tools anymore. My sister mailed me the ECU E38 part number 12617630 and service number 12612384 because I thought (boy was I wrong) that it would be a walk in the park because hey, I watched a few YouTube videos and it is so easy. Anyway, I went with a tool U-Link NT from a guy who is known as “usbbdm” and he posted a video U-Link NT e38 canbus programming. I was able to get a “full flash” backup and verified it 2 times. All checked out good using the U-Link NT program. I sent my dad an ECU (with same part and service #) after programming the backup flash that I had backed up from original. I thought it would work but to my surprise, it didn’t. He tried to do the 10-10-10 ECU relearn and that didn’t work either.

Can someone please help and take a look at my bin file that I backed up. Maybe there is something wrong with it.

Likely the slave don`t match. You need to sps it with vin and than clone it.

When you say “slave”, do you mean slave CPU? I actually opened up the donor e38 ecu and backed up via U-Link BDM method to save bin for slave CPU and also flashed that to ECU. I have attached bin if anyone can look at it.

The attached bin does not contain the tac module calibration.

I am not sure about these pcms, but in the earlier ones slave data (for the TAC) was 512 bytes of data, stored in the secondary CPU, I think in its internal eeprom? Is that the same for E38?

I appreciate the replies and I gathered some information for myself in the future. I will take note of the SPS VIN programming for the future before making a BIN backup. For now, based on my situation I just ordered a replacement E38 ECU from eBay and they were able to program it with VIN that I provided and also did AFM/DOD delete. Paid $200 for everything including shipping. My pops said that my Silverado is up and running and that the only thing it needs is a crank re-learn which he will take care of. Thanks again everyone!
