I hooked up to the car and tried to read the calibration and no success yet I'm waiting now. hopefully the vats just has me locked for 10 minutes or so. Successfully connected to ALDL Bus and Reconnecting to ALDL Bus , repeatedly over and over on prompts in flashhack. Makes two clicks when it connects and pops up unable to load kernel. Fans do not kick on and when i go to eehack it reads all kinds of weird numbers and codes off and on without the engine running. still no start.
You might need to disconnect battery. I suggest you flash this pcm on bench. It is very fragile and prone to bricking in car.
eehack is configured to work with v8s[that can explain the weird numbers]. There is a modfied version to work on v6s floating around the site but can`t find the link.

I tried all that, so I pulled this pcm out and have it on my desk right now. wiring is hooked up as follows Black plug, 30 and 31 12v, Blue plug , 3 12v, 1 ground, 30 serial data. Still doing the same B.S. chances are they did something stupid and bricked the pcm before I tried to read Calibration. Just gotta do a little more digging, if there is some difference ill figure that out. So the 03 P59 i have was a brick and i fixed that after i cloned it, saved the file on my desktop one night when I was drunk with Hammer. Cloned it and fixed the old one. Don't know about the lt1 or 94 v6 this is my second one. First one runs and i drive it and been tuning it.
This wiring is for lt1 pcm. for v6s is totally wrong. I hope you didn`t fry the hardware.

b14 b15 B+
B32 Ground
B19 serial data
Blue
C3 - ign
c17 ,C1 ground
Lets see if you get any communication than might do some more tests.
Shouldn't have if I had no ground on the black, everything was dead. Had some connection in the car but something was keeping it from reading.Originally Posted by kur4o

You might got lucky both circuits should have protection for short to battery.
Still never worked though from the beginning. I just ordered a spare Pcm from ebay . Kinda makes me mad to get it towed here where I have everything its like $120 and its less than half a mile from the tow service to the car and back to my house. No clue, I did what I was supposed to do with it in the car and would not read. I would be much farther ahead to build the trans and ls swap it. Thats more money though.
i don't think VATS will stop you from reflashing that ECM,
can you confirm are you using the EE flash tool or the P66 flash tool within flashhack?
when you get it hooked back up if you still have problems please post a log from the debug section and maybe we can see what's wrong.
It says EE Bin Converter in tools so im assuming that means EE Flash tool. I only have a snapshot from De-Bug in car with my computer hooked up. Trying to think of a way to host it , hold on.
the ee bin converter is always there
and why in hell would you use the EE tool with a P66 V6 ECM
go to the tools menu
select tool
my tools are easy to use but they don't hold your hand with simple stuff like 'selecting the completely wrong ECM'
change to v6 tool
plus you need to actually read the text that appears
you will see either
orCode:flashhack Version 1.1 Configured processor EE with interface ALDL 8192 Serial This is a flash read/write processor for the 16188051 and 16181333 ECMs used on 1994-1995 LT1 engines.
it should be totally obvious if using the wrong toolCode:flashhack Version 1.1 Configured processor P66 with interface ALDL 8192 Serial This is a flash read/write processor for P66 V6 ECMs used on 3100 and 3.4L engines from 1993-1995.
No TSIDE communication. Whatever that means. OH no I fried it.
Went to desktop with my ALDL cable. Selected p66 Flask tool "includes 3.4l" She's talkin now. I don't think I fried anything I figured out where my power issue was. Sure ill have a problem creating and modifying the bin.
Got it to read and created BIN plus loaded p66 XDF File . I am rather perplexed by the BIN File. This Might Take some Time. It is working now as far as I can tell.
Disabled VATS and Maxxed out frequency on other two VATS options. PCM is flashed on the desk. Worked Flawlessly.

Went in to tools selected p66 on my desktop. Read and write in about a minute each. I had a power issue though and that's why it wasn't connecting. It would have worked in the car if I just selected p66 Flash in the first place. Completely forgot about the tools because I have been on lt1 for the past 2 months.
