Haven't found an answer yet so here goes the question.
29C256 chip with moates adapter
pp2
aujp1350

I noticed the aujp is only 32k. do i need to stack?
all i did so far was burn the .bin onto the chip.
i put it in the car and it starts fine but the ses light won't go out and i get nothing at all when grounding the aldl.

i haven't edited anything yet cause i wanted to make sure the base .bin from the net worked.

what did i do wrong? i imagine it's running in limp mode at the moment.

 

Yes, you are running on your Limp home chips if when you ground the ALDL it doesn't blink code 12. Check to make sure the chip is in the zip socket the correct direction. Do a “verify” with the PP2 software to make sure the bin file is on the chip. No you don't to do a stack the bin files because only one will fit on a 256 chip.

The bin files are 32K. That means 32 thousand bytes. There are 8 bits in a byte so a 32,000 byte bin file is 256,000 bites. 256,000 bites is the size of a speed density PROM.

 

The correct direction is with the arrow/notch on the chip pointing towards the zif handle correct?

 

Notch toward ZIF handle in PP, but away in moates ECM adapter. AFAIK.

 

I am new to programing and I am having the same problems
so if you figure out what is wrong please let me know.

 

Tried flipping the chip around. So now the arrow points away from the zif lever. Obviously the car still starts but now the cooling fans come on and stay on. So is this the correct chip placement?
The ses still remains on with no codes.

 

When the cooling fans come on and stay on you have tje chip in the wrong way.

 

Okay.
I noticed that the service profile is damaged on the bin from diy-efi. I also noticed that when I go to edit buffer on the pp2 it shows me all zero's. It says the chip's not blank and can be reprogrammed. I have no erase device button.

I'm supposed to be programming in binary correct?

Is my copy of aujp1350 bad? Could this be why I can't get this thing to program?

 

You have to erase the chips with a UV eraser. The pp2 can not erase PROM's.

 

I have flash proms.
AT29C256

 

Ok. Finally got rid of the double 0's. Still have the SES light remaining on problem.
When I program with the pp2 i get the message "device verified to buffer" shouldn't i be getting "Device is programmed"?
And yes I am actually clicking on the program device button.

PLEASE help

 

I am having the same problem with my chips. I am wondering if
the chip adapter that I have is bad. I have removed the factory
chip from the original memcal and installed it in my adapter and
I am getting the same results. My next step is to solder in a zif
socket were the original chip was to completly do away with the
adapter. I hope this works. I will post what happens when i get
it completed

 

Hey Guys, I am having the exact same problem. I was under the impression if you are using the flashable proms like the 256T, then you do not need a UV light. Have any of you made in progress with this problem?

 

I have figured out that the adapter that i had was no good. I took my stock memcal and removed the original chip then I ordered a zif socket from radioshack and soldered it in place of the original chip. works perfectly every time. when removing the factory chip I used a very fine point soldering gun and it came out fairly easy just remember to take your time.

 

I actually never did figure out what was wrong. It just started working one day. It seems, Craig nor I knows why, my memcal needs the stock prom on there with the adapter and zif.
I even had Karl on the phone with me going through a burn and nothing was different but things started working with the above setup. Don't ask me. I think my car's retarded.
