Need 89 vette apkc bin

[bfsangli]

Hello, I don't have that file, but what's weirder is I have no record that file even exists. How are you planning on re-programming it if you can't read it? :)

I planned on using the moates adapter and burning an sst27sf512 with it

I did a thing with some paperclips, since noone appears to have this bin anywhere on the internet i am going to put it here for those who were as lost as i was.

APKC 1304 BIN

IDK if this is a good read but i tried. someone may want to verify it.

The checksum is wrong, so, not a good read :(
With a hex editor, it is calculated from 0008-3FFF and stored at 0006,7

I dont have the burn2, i was using a willem eeprom programmer, could this be the problem.

After i read the chip i used the verify function and it said it matched the contents of the chip, so i guess either the chip was bad or the programmer is not working properly.

Upon key on, the cpu verifies the checksum and if INCORRECT, it will rapidly flash the check engine light. If the check engine turns on at key on, then turns off briefly then turns back on solid. That means it passed the checksum verification.

The Willem should be fine as well as many available. We just need a good read. I haven't found any of the tables wrong in your read although I only checked a few, so, you are close :)

It should be a 27c128, some programmers are better if you choose 27128. You will have to see how yours acts, these are very old chips so contacts are sketchy :(

How would i verify a good read im not really understanding of the checksum concept yet

[In-Tech]

It's fairly complicated to type, feel free to post your reads and I or others will check for you. Most programming devices will give you a total checksum upon read. Keep reading till it comes up with the same number total checksum EVERY time.

Is this happening in the car?

[bfsangli]

no it just doest fire the injectors

Doesn't the Burn2 read 27128 chips? I know it can't program them but thought it could read them.
