Ok I am at my wits end I am using the E6 mask. I have three of the 27SF512 chips. It seems like one out of 25 burns actually work the rest just give me a flashing CEL. I have checked the position of the chip while in the burner, checked the offsets. I am using a 64k bin so my off sets are 000000 -> 00FFFF. I put the chip in my burn2 erase the chip verify its blank ( by the tool) then load buffer from file, program chip verify with no errors. then put in the truck and no go. I have also noticed that if I erase the chip and read from it its not blank.

is it my laptop , my burner or chips ?

 

Have you tried using the Flash and Burn program that is for the Burn1/2 specifically?

 

Yes I have tried both, I am going to run some tests in the morning, I dont think the chips are being arased properly. I am going to erase the chip verify, then read the chip inot the buffer and check to make sure its erased.

 

Are you 100% sure you are installing them the correct way in the adapter? The notch goes up when in the burner, but down when in the pcm. Well, at least that is how it is in mine. I know I have put the chip in the wrong way in the adapter and got a no start condition. Turned it the other way and all was fine, so it didn't hurt anything.

Other than that, I'm as lost as you are as to what would be wrong.
