other than diy-efi.org?

 

Yep, there are.

 

Within the "Introduction Article" that Tim wrote, there were a few more links to other sites that relate to eprom burning. But, basically DIY-EFI.ORG and this site appears to be the most comprehensive that I have found that is readily available to the general public.

GM ECMGUY has some interesting information, but I believe he passed away, so there is no new information. TunerCat's site has some links to other sites also, but they are more individuals' web-pages.

 

The corvette forum just added a diy prom board.

 

Coming up on 2 years ago.
Man he had some real smarts, and experience.
He gave away so much information. All of it good.

 

What wax to use, and prom burning.

It's a joke.......

 

I will check out gm ecm guys site & others.I have got info from some of them but forgot the links.I want to learn more but am gitting in a rut.More like a need for greater understanding of the ecm and burning.I think we should give those vette guys help over there.I just think someday everyone will tune thier own efi.We can help it move along,ya know.Thanks for your replys

 

You are at the point I was about a year ago. That is when I started getting deeply into the hac and then created a "disassembly" and began tracing every instruction in the hac and documenting the instruction in the diassembly. That is when I really started to learn what the ECM was doing and how I could alter the way the instructions actually work to my preferences.

For performance, I did a lot of trial and error. That was more to get an understanding on the effects of elevation, air temperature, engine operating temperature and their affects on tuning. I quickly found that a 160* t-stat made "consistent" tuning (so the car performs the same hot, cold, and as optimally as it can at various elevations) difficult and switched to a 180* t-stat.

 

Guess you missed the posting about the Source Code.
That's what is needed to be done.
Too many folks just look at WOT and some drivibility, when there is such more going on.
LOTS MORE

 

LOL, that is what I was thinking, but did not really want to say it out loud. when I saw a post that read "how many guys do I need to take off my hood" I quit going to that board. I figured if 20 or 25 guys had to answer that, I was moving on.

I lurked there like 5 years ago, after several months just moved on. The few times I went back to check on them, things hadn't changed. I'd thought about starting a thread about if clockwise or CCW buffing would be best. <g>

 

C'mon!!!!! EVERYONE knows that CCW is da best!! Duh........

 

You gotta admit, you see some pretty dumb stuff pop up around here every now and then...

 

Yup, done my fair share of that, specially with the prom stuff.

I think you would be pretty surprised what some of those waxers come up with. Well, probably not you, but maybe others

One guy is halfway through the interface of getting the mileage displays to work on the dash after a speed density swap. That isn't prom burning, but the Excel macro for taking 8000 frames of capture into Diacom, cutting and pasting that table and the Tuner Cat VE table into the program, and hitting 'Play Macro' has some pretty ingenious methods at arriving at a solid reference BLM. The first version was to check funcionality of it. The second version added a macro to scale down the file from 45MB to 300KB so it could be easily SHARED and then expanded once downloaded.

The upper VE table version is nearly complete, but there need to be checks to let a user know when the data useage would not be appropriate because some people might get caught up using it and mindlessly cut and paste. The spark retard, injector pulsewidth, and verification of actual closed loop operation has not been refined enough in the upper VE table yet and would probably cause someone to make fradulent changes if they didn't look at the data before hitting play. All in all, it is one heckuva good start for getting the VE tables squared away.

Now if you'll excuse me, I need to go read my "Polishing: Your Thirty Day Daily Guide to Shine" -Matt-
