2002 Pontiac GTP 40th anniversary cant read or com with pcm

[Kdog]

hello fam, im new here and have a question. i have tried everything it feels like to trty and read a p04 i believe, with a jet dst 140005 hardware and win xp/7/10 on a laptop desktop and with my msi claw. got the farthest with msi claw(believe it or not) and always get stuck on cannot communicate with con b2 or c1 and when it does get through(pcm hammer 2.0 with po4 binary beta test version) it says error cant communicate with unknown pcm in every scenario. my in cab gm tuner(superchips dashpaq+) says the same. am i doing something wrong? i tried adding the tables, configs, ect but idk. hoping i didn't pay 300+ on jet dst for nothing. says i still have 4 license to use, like to mention it does the same for a custom tuned pcm from a 2000 gtp i have for my added performance shift button(working) and the junkyard 2001 gtp pcm i have in it now. my buddy's 96 k2500 suburban c6p w vortec 7400 black box pcm. says unknown pcm once more i feel like its hardware/ pc/ user error related as no license used up and software indicates ive connected to jet dst interface with 3.1 as stated firmware. i can post logs later when i get em off of the 3 pc's and reply with info on any questions needed for the help. thanks in advanced (i was a certified mopar tech, license ended in 2019 i know cars but it aint as easy as plug in pod and go to pc and pull vehicle up for pcm updates ect) feelin brand new to cars again. love to learn it.

Hit get properties and post up the output. If it says "cant communicate with unknown pcm" or something to that effect the operating system ID is not in its database and it doesn't recognize it as a P04. There are several types of P04 so if you can give us the service number on the PCM that will help, then we can do some sleuthing to try and figure out which version it is.

Its also worth mentioning that reading and writing in car will probably not be 100% reliable, and if you can make up a bench loom for flashing that will be a better way to go.

i remember yalls warnings, and i will post # from the 2001 JY pcm that's stock that i have in it right now, and it came with a zzp 2000 pcm in it i think, i wont have the original 2002 pcm #'s from the cart itself and this is why i cant get into the 2 pcm's i have. only am able to get the service #'s as i think i have a bad connection as stated in another post i believe i quoted you in. your legendary antus, i see you all over the internet as i research and try to build my knowledge. the JY has no CEL but the 2000 zzp(i think) has a hiccup or glitch everyone in a while and throws a p0171 but has some switches turned off as far as ho2s and some others. but it has a select shift(technical terms from gm service manual if i remember right, anyone need a wiring diagram copy?!) or performance shift turned on and she feels like the 2000 i used to own. and I'm wondering if they had the 2 fans ion this little two position switch as i have no idea what it went to and found no loose wires to chase in the car.

promise ill post pics.......keep in mind im using a msi claw win 11 and a jet interface cuz Fuggin merica!

Just wanted to give whoever is following this a little update in case you didn't catch the images I added to the first post

I don't know if this matters but I found a po1 on inside of the pcm on the board and aswell as some stuff stamped on the inside of the cover......title of the cover pic is the stampings

Wanted to let you know I got those pictures posted with the service numbers and Hardware numbers I know or you wasn't really looking for those I also pulled the lid off the board and you could see it says po1 I was curious on if that is indicating the computer type I thought all these were po4s but it's just really curious to me that it shows that on the board it also has some numbers with it kind of looks like it might be the security tag or the key I'm not sure if it's either or or not relevant at all there's also the numbers 322 917 in the middle of board

Got the numbers in the first post. Ill check that osid is in pcm hammer and take an educated guess what type of p04 to classify it is. Watch this thread. The P0x numbers on the pcb mean nothing its pcb layer numbers 1-x depending how many layer pcb, not pcm type.

[antus]

That OSID and service number is already in the pcmhammer 2 preview version. Can you post up the debug output, it should not be saying it cannot recognise it.

here are the logs sorry passed out in the car last night laptop died ect. didnt use the msi claw used a dell latitude d20 came with xp has win 10 atm.....
2002 car made in november 2001 with a 2001 pcm, other pcm i cant read says unknown is the 2000 gtp pcm intense? or zzp? has zzp parts and the zzp stamp under hood. wire i found burnt up led to pin 21 on pcm for performance shift, i ran a switch to it and it works with the 2000 pcm, and um......a switch by steering colum on1 off on2 i think was for fans but it only sends power to 1 or 2 so maybe they had something else wired in, empty gauge pod thats populated now lol i wonder if it would bench flash and gcm is interfering cuz i can plug in an expensive 2 way scan tool and it asks me if its a 2001 or 2002 vin 1 car with same vin# just some info i thought maybe would determine car fucked n ur program is good. oh and only 1 code ever shows as history for read 2002 and everything that hasnt passed or is current shows for 2001(feels like a normal scan environment) thought that was weird af.

i fixed a lot of pins on the pcm that glitched everyonce in a while, see the solder crack around base and cold wiggle a little bit. thats what happens when u use a k&n "cold air intake" without the pcm bracket, not even ziptied up. needless to say it has a factory box n intake on it now with the pcm from the donar 2001 gtp checked pcm plugs they were dirty on outside but i believe it isnt a wiring issue, think ive eliminated all those.
