What is the service number of the ECM(s) in question?

Some of the earlier truck ECMs, such as the '7747 needed the disable checksum at 0x04, not 0x08.

Also, you need to "turn off" emulation before disconnecting the emulator from the laptop.

a 93 Typhoon would indeed be a 7749... is it running $58 or code59? i believe most if not all of the "stock" code59 tunes had their checksums disabled in the BINs to begin with.

Im running code 59, and yea, my starter bin was setup without the checksum disabled. And it worked fine for like, a couple weeks and then all of a sudden stopped. my starter bin will still start the truck, and i can upload my modified bin and it will work fine, until i go to start it again. and it will start, but it runs super lean, and with the timing super advanced. Ive tried to take my starter bin and make a new modified bin, but as soon as i modify it it seems to do the same thing, even just doing a bit of work on the F29x table and what wideband to use...

What happens if you burn the modified bin to an EPROM?

wish i knew, i dont have a burner or a chip....well, actually, if i could get a way to do it with a universal burner i could do it at school (im going for electrical engineering) i could try it, but i would need to know what kind of chip it was and whatnot.
