93 S10 Reading Jet Chips

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.

Good news. Oh, just fyi, the factory chip isn't a read-only. It's just that the moates burn2 can't program it so he calls it read-only.

The updated chip is working better. One more problem on the $E6 adx it says

For data logging "Knock Retard" instead of "Battery Voltage". The bin must be change at L51FE to support this.

Crud, that explains why the constant, unwavering 24 degrees of knock retard when logging. ALDLDroid must have used the same file as its showing the same. Lots of "borrowing" between these software programs.
This is mentioned several times before, but the reponses all seem to be saying just ignore it. If I actually wanted to make the knock retard useful how do I find L51FE? It does say

To data log “Knock Retard” instead of “Battery Voltage”; change the value at L51FE to $020F (Knock Retard). Stock value is $00A1 (Battery Voltage).

Found it, it's the last scalar in E6V5 xdf.

Hiya, I try to collect stock .bin files when I can. Would you mind posting the stock .bin and the broadcast code if you have it?
