I need to disable vats on my 89 vette, wont start and i need the apkc bin file. However i cannot seem to find it anywhere online or on this forum.
Does anyone have it APKC 1304, i would greatly apreciate it.

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 itQuote:

IDK if this is a good read but i tried. someone may want to verify it.
Doesn't the Burn2 read 27128 chips? I know it can't program them but thought it could read them.
The checksum is wrong, so, not a good read :(Quote:

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
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.
I tried putting it in again, reaseating it a couple of times and changing it to 27128 even though it is a 27c128 like you said.
Every time i read it it would give me the same exact file down to each bit, windows FC verifies that the resulting bins are exactly the same as the first one i got.
Im wondering if i manually look at the differences between the bin i am getting and another one such as ARAR if i could peacemeal them together and manually correct the differences?
Last 89 Y-car release. Can be used in 86-88 - disable Cold Start Inj. Scan tool enter as 1989 Y-car
Is this happening in the car?Quote:

Here is the file you posted with the checksum corrected and VATS turned off. If you don't have the rapidly flashing check engine light, it has passed checksum verification so there is something wrong with your Willem is all I can think.
I just ended up comparing the file cottonpicker posted to the one i read and all the values were the same so i just modified that and slapped it into my memcal. Fired right up. Thanks for the help guys.
