Default 87 4+3 ECM Chip

I am looking for an 87 Factory 4+3 ECM chip. Anyone got one they don't need or know where to get one?

If you are talking about the prom/chip that goes into the ECM I have my old one. I bought a new one just a few weeks ago and put it in trying to get rid of my codes, but I guess the relays were the problem. Nevertheless if you want it it's yours. I'm not putting it back where it came from. Pay for the postage and it's yours. My car is a 4 +3.

If you want it email me your address.

Hey Bro, it worked, The Custom program from PCMforless works with the factory chip but not the Superchip. Thanks a million.

My only question is do you have a MK2 or MH5 overdrive? The chips are different depending on which you have.

Don't know, how do you tell? The chip I got from headdoc seems to be working.

I still have the super chip. I don't know the exact performance specs, but if anyone wants to give it a go, let me know.
