An ALDL address that was pointing to a redundant TPS A/D raw count will be changed to this stack value. (Who needs TPS% AND TPS raw?) Now, changing that address using the patch method is simple enough. BUT, when you have new code like above, that you need to add to the program loop....
How do you do it? I'm guessing I have to disassemble the whole binary, stick that in the main loop, and assemble it. I HOPE that's not the case, because I have had extreme difficulty just disassembling the stupid binary.

Also be very careful where you put stuff. 99.9% of the stock addresses are in use and needed by the stock code. The raw TPS may be the actual TPS value thats stored from the A/D read. In that case, most, if not all other TPS values may be based off it.

Re: patch method demo
The S19_pat utility is the issue, it won't run correctly on the newer/older Windows O/S's. I have ported it to WIN32 console mode a while ago. I'll attach the new version here as a zip file. Note that it has a trailing underscore ('_') to differentiate it from the DOS version.
