How do you remove the stock chip from the plastic holder without damaging the chip? I want to read the stock EPROM as a starting point, but it won't fit in the ZIF of the AutoProm unless I get the plastic holder off...

 

i used a flathead

 

Yeah, I tried that. But it seems to be glued in or something. I finally used enough pressure to break the back ribs out, and the chip never moved. I was afraid I was about to break the chip, which sorta defeats the purpose of trying to read it in for a starter bin...

 

oh you ment the chip itself, i thought you emnt the blue cover, havnt removed the chip myself yet, take a look at

and see if you can find yuour stock bin.

 

This is an older EPROM socketed ECM, not a (correction) memcal with the blue container.

And I was asking about the "correct" bin in another post I made tonight. It seems that there are several "possibles" but no way I can see to differentiate one from another. Likewise, there seem to be several possible definition files to use, and no real key I can see to determine which is correct. Unfortunately, there has been no responses in that post yet...

 

your current chip should have some code stamped on it and thats the one to look for,

 

Yeah, I figured that out too, but take a look at the second and third post in my other thread here. I expect I can make a guess at the obvious ones and will probably be ok, but I would rather not guess, and that also leaves me not knowing what the files with different names are about.

 

With the chip and carrier laying on a table, firmly press the chip down. This will disenage the pins from the carrier. You can then pull on one side of the carrier and get it way from the pins. Release the chip and half of it should pop up. Pull it out and your done.

 

Well, if I wasn't before, I guess I'm committed now. I figured I must be wussing around with it since it seems it should just push out. So I pushed and worked back-n-forth and wiggled and alternated, and pushed harder; till it finally gave. About half the pins came loose, the other half didn't, they just sorta rolled back up and over like spider legs, and 3 of them broke off. And it still won't come out of the holder with the remaining legs shaped like candy canes but still firmly attached.

 

10 minutes of my time, hopefully not wasted.

Well, too late for this one (which I broke trying to just push it out), but maybe another clueless newb can benefit from it. It'll also help when I do my second 7747. Never occurred to me to push in on the sides like that, but clearly it should have been obvious.

Thank you very much for your time, sorry to be so clueless. Never having fooled with computer hardware like this before, I guess my brain is a bit in over-load and common-sense is in short supply.

 

you make it look too easy.

One of these days I need to get around to doing this to my 4cyl 88 fiero...that thing has serious tuning issues right from the factory.

by the way. your smoke alarm/smoke detector needs a battery

 

I guess thats partly my fault as well for not giving explicit directions on how to remove it What may seem like common sense to one isnt common sense to another. Like me pushing on a door that opens outward or turning my wrist to check the time while holding a cup of coffee or a can or soda.

 

Heh, no worries. If what should be obvious can be over looked or anything screwed up, I WILL find a way to do it. I just do my best to neutralize my opportunities for stupid oversights, and deal with them when they occur anyway...

 

I just did this last night on a friends prom. I just used a needle and slightly bend the pins inward to get over hte little lip that holds it from falling "away" from the holder. I can post pics if you want. I cant get Jprevost's image to show up show he might have a better form.

 

It's not an image, but a short video he put on putfile. He just kinda gently flexes up and back down the sides, along the plastic "teeth", so that the pins pop out of the holder a bit and bend slightly in. Then it slides right out.

 

i dont know why i cant get the vid to work, but thanks Baddog.

 

yeah, i had a heck of a time on one or two of them. I found that the best trick is to take a set of side cutters (dikes) and clip the middle supports of the socket on top (not cut out completely, just cut in the middle). Then you take a jeweler's screwdriver, and gently pry back and forth until the pins pop out. Once you seat the chip back in the socket, all you really need is the plastic surrounding the pins, to push them into the socket contacts. The ribs don't do a whole lot other than to hold the holder together.

 

My way only requires my fingers

 

Its not too hard. Press the chip down in the carrier while pulling one side of the carrier out, and half the chip pops up when you release it. Pull it out and your done. Takes about 10 seconds and doesnt damage the chip.

 

Ok,
I got tired of my sa dial up connection trying to download that putfile. I also wondered what a free host was doing to make cash. So I closed the window.
Locked up Firefox quite nicely!

I'm sure JP did a nice job on the vid.
If it's thought to be worth while, I can host it.


Looking at your watch......

 

AVI file no workie when viewing thru browser.

Anyway, it shouldnt take more then five seconds to remove the chip. In the carrier there are clearances for the legs of the chip so it actually engages the carrier and cant be removed without possible breakage. Once the chip is pushed back against the two loaded fingers in the rear of the carrier, itll disengage and will pop right out. Shouldnt have to flex the sides back and fourth. Cant view the vid, though, so I cant say for sure how jon does it.

If anyone needs clarification, I can post several pictures showing how.

Basically the first thing to do is lay the carrier down and firmly press the chip down untill it bottoms out.

Next step is to pull one side out with your finger or thumb enough that itll let all the pins clear.

Next, while still pulling on the side, release the chip and it will pop up.

If the chip has popped up, carefully push on the two fingers at teh rear and the chip will come out.

 

Is that your smoke detector beeping in the background?

FWIW, you’re not trying to read a turbocity or similar aftermarket chip, are you? I noticed that those sneaky bastards superglue their chips to the carrier making it a PITA to get out if at all, usually you can’t do it without ruining the carrier (soak the whole thing in acetone). It’s actually easier to steal a socket off of an old ECU and drop that in your prom burner instead.
