260z project that needs some tuning help

[1project2many]

I found another place that might work, but I wasn't sure if I should do it, see pic.

Hi Larry,

I realize there are several people working on helping. I hope this isn't too much. You will need an xdf, an ads, and a .bin file to work with so all the suggestions you are seeing are valid. I can also see there is difficulty selecting the correct files when you don't have a .bin to work with.

I believe this tool allows you to download the bin "in the raw."

You will need to select the chip size, a file name, and maybe the start and end addresses for the file. If you're willing to try this, and if you can get a file, we can probably figure out the necessary details to get you started.

If it's available, I would select 32k for the chip size. I would watch the two boxes on the right to make sure the top box contains 0000 and the bottom box contains 7FFF. The "Output File" box appears to be where you type in the name of your file. Is there a drop down button on the right side of this box? The image is a little blurry for me. If there's a button, does it allow you to select options for the file type? The file type or file extension should be "binary" or "BIN."

Maybe a TunerPro videos will help.

I tried the $AO and it didn't open. Here's a pic of my ecm and the name of the place that supplied the electronics for the kit that is in my 260z.

The computer pictured is a GM computer that uses a 4K Chip, typically the 2732 EPROM. The computer pictured does not have a FACTORY part number LABEL, so it's likely the part number on the computer has a "TYPO ERROR"

I hope you all had a great Christmas and New year's; I have been trying all of the different things in tuner pro, and it looks like we are going to need to take a chip that I have and try to get the bin file out of it. Every way I go into TP just needs a bin file. I have also downloaded other V6 files to see if 1 of then would open this up and had no luck.
The good thing is I'm getting to know Tuner pro a little better.
If there is someone that could read the file on one of the chips I have and would like to help that would be great.

I sent you a PM with my address, I am in Michigan, so if someone closer can help no problem just let me know.

The DIY tools to erase / read / write TBI chips.

Thanks Sledhead2. It would be great if you could do that for me. I do have 1 problem, out of 10 chips I have I don't remember which chip was in the ecm when Boosted did the work on it.

[Sledhead2]

You can mail more then one, but get some masking tape and label them in some way. this way when i save file i will name it the same.

Every way I go into TP just needs a bin file. I have also downloaded other V6 files to see if 1 of then would open this up and had no luck.

I think it would be helpful if you posted one of the other .bin files you tried opening in TunerPro.

Larryz260 has sent four chips and an eprom emulator to me for reading. Files from the chips are attached. The correct ecm number is 16144288 and the definition files and stock calibrations can be found here.

The main differences between the attached files are changes to fuel delivery through VE tables and injector base constant.

The file in the emulator does not match any of the chips and I have not yet figured out the pattern to unlock it, if there is one. Larry, does your car have a working check engine light? Do you remember if it was on with the emulator installed?

[Larryz260]

Thanks for all your help, I do have a working check engine light and it was not on with the emulator installed, it will come on sometimes as it's warming up and when I look up the code it is a rich condition, when starting it is very rich.

[Larryz260]

good morning 1project2many, if you are having problems with the emulator, do you think it might be better to just get an emulator from Moates?

[1project2many]

Tunerpro RT connects to your emulator and seems to read from it but the file it produces is not a proper calibration. If the ecm operates normally with the emulator installed then I have to believe there's a valid calibration in the emulator.

You could buy a new emulator but there would still be the question of how to load the calibration into the emulator so the ecm can read it. There are multiple methods for connecting a 28 pin chip to a 24 pin ecm.

[1project2many]

Progress. I have identified 260Z9011 as the calibration installed in the emulator.

Have you had a chance to download the definition file from the link above?

[Larryz260]

I have not downloaded them yet. I will see if I can load those to tuner pro rt, I think I can do it.
