[pics] Flash chip replacement progress
Well, here's my little write up thing for those of you that might lose your computer the same way I did .... :rolleyes: :rolleyes:
PCM cracked open: (DO NOT take this apart with the torx .. use the hex wrench .. I busted a torx cuz the damn things are on so tight!)
The EVIL :reddevil chip :
The board with the flash chip circled in blue:
Wrap foil around and use an 800*F or so heat gun on it.. and just put some pressure and it pops right off... : (foil is a great heat insulator and doesn't conduct much heat itself either)
The bastard chip:
The whole board now:
The blank pads where I will put the new flash chip when it gets here:

Re: [pics] Flash chip replacement progress (Glock'94)
Whoa Curtis - got some guts there tackling this job but I guess its not as risky since the ECM is dead anyway. Are you going to put a socket in and use a socketed version of the flash device ? Be sure you get the correct version of the chip because that ECM sees pretty drastic thermal stresses under the hood.
Thanks for the pix. I was wondering how things looked inside the computer.

Yup.. when it comes to things that GM REALLY over charges for ($230+$375 core).. and that I was such an idiot about letting happen (let the battery die right in the middle of programming :rolleyes: :rolleyes: ) I will do it myself the hard way and see if I can fix it before I go out and by a whole new ECM.
No, I'm not doing the socket as I shouldn't have to do this again ... plus it's pretty difficult to get that socket on there.. Andrew uses .010 solder and a soldering iron the size of a pin!!! (needle pin .. not PEN) ... It's around .8mm :eek:

You are brave!! :) :) What do you mean by "put a little pressure on it and it pops right off". You didn't use a chip puller to yank it once the solder was molten?

No need for a chip puller. The chip leads don't go through the board (plus a plastic chip puller would have melted). The leads aren't straight.. theyare curved and go back into the chip ... so when I solder it. i just attach one .. then line it up.. attach another on the opposite side... and then go to town soldering the rest of them

Re: [pics] Flash chip replacement progress (Glock'94)
Are you using any type of elec static protection when you handle that stuff. I was an electronics tech in the navy and we had to wear Elect. Static grounding straps when we handled circuit cards because one blast of static elec could fry those type of chips.
