93 S10 Reading Jet Chips

**donf** · 03-17-2020

Thanks for the tip, the line 4000 from the Jet chips says

Code:

0e06 5c56 020e 000e 0478 300e 5e4e 025e

For a sanity check I looked at the $0D bin I pulled today and there was not even 4000 lines. 366 is its last line in Sublime text editor. To double check this I opened up another $OD bin I downloaded here BYJN and it was 366 lines. The owner had taken the jet chip out for some reason and is currently running the stock one. I will pull the info from it tomorrow and see if it makes more sense. Its entirely possible from looking at the data that the chip is corrupted. Not sure though.

Hiya,
The file for a 27512 chip should be 64k in size. It doesn't sound like it is being read correctly. Are you using a burn2?

**In-Tech** · 03-17-2020

Here is a standalone version of burn2. You will have to rename it Burn2.rar as it is not really a .zip file and this website won't let us upload .rar files.

Read the chip using 27c512.

Thanks, yes all the files are 64K. I did read the Jet chip using the 27c512 settings in moates software. Not really sure what is going on. Since it's the Jet chip and not the original that is not reading correctly, I will wait and see what the original prom reads like tomorrow.

upload the bin.

Thanks for the feedback. I think posting modified bins here publicly is a no go. I saw a moderator post that, I did not know and have been guilty of the same. In this case it may not matter as its not functional. I really am not worried about it, its more curious about why its not reading correct rather than a need. As long as his original chip reads fine this morning we have a good starting point.

Here are the settings I used to read the chip. I think these are correct for a 64k bin on 27c512. Even after reading the chip again this morning the basics are not even remotely correct. The whole spark table shows -1.4 degrees timing with a few variations. The owner of the truck did stop using the jet chip on his own and put the factory one back in.

The factory prom reads perfect. So the Jet chip must be corrupted. I ask the owner if he disconnected the battery before removing the chip. He did not know, so I suspect some type of spike corrupted the chip. Thanks again for the help.
