Hey guys, I have never actually visited the DIY PROM board, so nothing I have read yet makes any sense. I would like to learn how to burn chips, particulary one for max performance and one to put in for emissions testing especially since I dont have AIR or EGR. Can some one explain to me the basics and help me understand the PROM lingo (sp?).
Thanks in advance

We can't explain everything to every new person that comes in. What you have to do is just let it sink in. Take your time with it and read it over and over. Just hang around and look through the old posts, start from the very first one. Look around at diy-efi.org for more info. Read through those old posts. I'm not trying to be a hard A$$ but that's the only true way to learn. Everyone on here did it the same way. It's just waaayyy tooooo much info to try to explain in one thread, much less one post. Then, when you have a specific question, ask it. And BTW, the performance part of programming has little to do with the cruise or idle part of it. When you are at WOT (wide open throttle) the ECM is in PE (power enrichment) mode which has its own set of instructions as far as how much fuel and spark to add so it really doesn't interfere with the "emissions" part of the chip so you don't need to have two chips. Consider this a first lesson of sorts.

 

Thanks for the post, I guess It will just take time to learn this stuff, and learn it the same way i learned everything else I know about cars. And i like the idea of one chip doing 2 jobs, if i could get it to tune a certain way at only WOT that would be great.

If you're running TPI no problem. I don't know about the '85 software, but '86-'92 all have WOT tables for fuel and spark which do what you're describing. Nice and tame at part throttle, nail the gas and extra fuel and spark come in.
