ID these chips?
Hey guys - just pulled the chips out of Pop's 951 to switch with a set of Huntley's. The chips that came out were labeled:
1267355183 (DME)
1267355131 (KLR)
are these stock chips?

Bah - car won't start with the Huntley chips.
Any chance I put one in backwards? I aligned the notches going in with the notches as they came out...
Any ideas before I yank these back out?

Did u use a grounding strap on your body when u did the swap?
if you lined them up correctly, all should be well. Try re-seating them.
As for the numbers on your chips, I guess they're stock because they look a lot like the numbers on my stock 86 951 chips:
1267355138 KLR
1267355235 DME

Just had the same thing happen on my car. I am having trouble passing the new DFW, TX emission test and tried to put the stock ones back in. Car won't start with stock chips, so I put back in the Superchips. Car starts.......Looks like I fried the old chips (or they were already fried as the previous owner kept them in the glove box since 94!) Another rennlister told me to go to Radio Shack and buy a ground strap so that will not happen next time.

Bah. OK, where do I clip the leash, so I won't be risking the stock chips when I reinstall them?
Interesting note - I heard a minute spark when I reattached the ground on the battery - not the usual occurance. I wonder if these chips were PREVIOUSLY toasted?

I know Computer guys that have the leash attached to their wrist and they ground it to the PC they are working on. Ground it to an exposed metal part on the car, under the dash where you are working.

Gents -
The above numbers are stock chips, prolly from an 86 turbo. The "83" chip goes in the DME, the other in the KLR.
For grounding, insure that you both TOUCH ground on the car OFTEN, and also wrap a wire around your wrist (bare metal) and tie that to a ground point on the car. You don't have to go buy a strap when you have scrap wire around.
As for the spark when re-attaching ground, chances are that there was an accessory on in the car which needed current upon reconnection. My car does it all the time, and it's not an indication that the chips were fried.
When re-installing chips, insure that the notches in the chips face the right direction (either look at the chip in there before you replace it, or find the square pad on the circuit board and face the notch towards that pad) and that EACH and EVERY pin is seated well into the corresponding hole. Missing either one of these steps can and most likely will cause a no start, and potentially fry the chip too.
HTH!

I've worked with eproms and other programable parts in the past and it is really hard to screw them up. They are not as easily wiped as one would believe. If you lined up the notches with the old chips and installed them in the same direction then they are correct. Chances are they have already been wiped out before you installed them. We used to use a static discharge gun to try and fry chips and most times it would not work and those things can really give a serious jolt. If you are stuck I might have some autothority chips you can have....banjo bolt too. Let me know.

Thanks guys, I'm assuming the Huntley KLR chip was previously messed up (I wonder if they offer a re-burning service?)
I am not stuck (as I have the stock chips) but my Pop might be interested in the Autothority setup, regardless - why don't you eme at wstudios@mindspring.com ?
Thanks guys!
