Successfully burned my first chip!!!!

Had a little problem with the size of the 29C256. But played around with the stacking and it works just fine. So it's just a copy of the dyno tuned chip. Now I need to start messing around with the fuel table and get the fueling dialed in.

Baby steps, baby steps.

 

Let me be the first to say "Congratulations". It's a bit of rush to do your first "mod" and actually see it work.

 

 

woohoo!!!!!! Great, I find it easier to just use an offset in my burner than to stack the bin up. Just burn the chip to the last "slot" and your ecm should pick it up.

 

I don't know why for sure, but for most people, that IS the BIGGEST step to accomplish (including myself in the not so distant past). Even with everything almost automatic, there's still a distinct procedure that must be followed, and that's assuming the hardware works, but without someone to SHOW you how to do some of this stuff, it's a little nerve racking. Good job!

 

The first of many as this stuff is totally addicting. Before you know it, you're hooked. Congrats!

 

I read through some post on stacking and saw some about using burning with a specific start and end on the chip. I tried it and it did not work. So I tried the stacking and it worked fine. The offsetting sounds easier but I'm not sure what address to burn to on the 29c256 chip.

Using Offsets on Chips



How to use offsets when programming chips:
If the chip you are programming is of a larger capacity than the binary file you are putting on it, you typically need to use an offset with
respect to chip addressing. This option is shown in the TunerPro RT program under 'Moates Prom I/O'. To program a chip, proceed as follows:

1) Ensure that all programs on the PC are closed, and then connect the AutoProm or Flash & Burn unit. If using a serial version of the AutoProm,
connect its power supply. Make sure, if using an AutoProm, that it is disconnected from the car's ECM.

2) Once the unit is connected, start up the TunerPro RT program. You should see at the bottom of the window a message like "Connected: AutoProm 2.5.A" or something similar. If this is not shown, and you instead see "Hardware Not Found", then one of the following needs to be checked:
a) Driver installation. If using a USB product, the proper driver needs to be installed and configured correctly. Check website for detailed
instructions in this regard.
b) Switch position. If using an AutoProm, there is a switch on the back (black horizontal) of the unit which needs to be placed in the 'toward the
middle of the unit' position. If it is in the 'toward the outside' position, then the chip burning and emulation functions will not work.

3) Assuming that (2) is achieved successfully, you are now ready to put a chip in the unit. Place the chip such that the chip notch or arrow is
oriented in the same direction as the ZIF socket handle, which should be toward the cable connections. Also, make sure that the chip is positioned
away from the ZIF handle, so that the empty holes in the socket are present at the handle end. The orientation and positioning of the chip in the
socket is CRITICAL, so make sure that this is correct. See pictures on website for clarity.

4) Under the 'Tools' menu item, select the 'Moates Prom I/O' option, and you will get a submenu. In here, you should do the following in the correct
order:
a) Select the type of chip you'll be programming from the drop-down menu. This will likely be either the AT29C256 or the 27SF512.
b) Pick the 'Load file to buffer' option, and navigate to find the file you want programmed on the chip. Select it, and it will be loaded to
memory on the PC.
c) Take note of the file size indicated in the message window. It will likely be one of four sizes: 4k, 16k, 32k, or 64k (kbytes).
d) Take a look at the top right part of the window, and you'll see the offset values. This is what we'll do next.

5) The file size, along with the chip size, will determine what offsets you need to use. When you change the offset values, you will notice that other
values will change automatically. Just make sure that the correct values are filled in for all four boxes before programming the chip. The following
table summarizes what offsets you need to use depending on chip used and file size:

File Size Chip Buffer Start -> End Chip Start -> End
4k (4096) AT29C256 000000 -> 000FFF 007000 -> 007FFF
16k (16384) AT29C256 000000 -> 003FFF 004000 -> 007FFF
32k (32768) AT29C256 000000 -> 007FFF 000000 -> 007FFF
4k (4096) 27SF512 000000 -> 000FFF 00F000 -> 00FFFF
16k (16384) 27SF512 000000 -> 003FFF 00C000 -> 00FFFF
32k (32768) 27SF512 000000 -> 007FFF 008000 -> 00FFFF
56k (57344) 27SF512 000000 -> 00DFFF 002000 -> 00FFFF
64k (65536) 27SF512 000000 -> 00FFFF 000000 -> 00FFFF

As you can see, the buffer (or file content) will be placed at the 'end' of the chip.

6) Once you have selected the proper chip, the proper file to use for the program content, and the proper offsets, you are ready to program the chip.
If using a 27SF512 chip, you must 'Erase Chip' first. This is not needed with the AT29C256. Go ahead and select the 'Program Chip' option. Follow
this action with a 'Verify' command to make sure everything programmed correctly. You should get a 'Success' notice.


Here's a helpful little quote from a post of mine. I had been burning chips for over a year and still had a brain fart when I needed to program a bin that I wasn't used to. As you can see above your have a 4k bin and your chip has 34K worth of space. So you need to burn with a device or chip offset of 007000 to 00FFFF Give that a try.

 

Ok. I didn't have the chip buffer set right. I'll try it next time.
