do you guys think that tpis or other companies read this forum? I'm sure they could learn a bit more about the ecm code....

 

Probably would not make a lick of difference in their products even if they did get their "learn" on.

I know now that "tuning for the masses" or ANY mail order custom tuning is just a crap shoot. I'm sure they can rough in alot of different combo's, but it wont be near as close or accurate of a tune unless the car is present and can be datalogged and tuned and over and over until correct.

The above is the reason I forced myself and still force myself to learn more and DIY it !

 

At one point in time, when DIY-EFI was hosted at Ohio State, there were even oems that participated. It was an incredible mind melt for some time.

There are all sorts of people lurking now adays, and some people even using multipul posting personalities to even steer threads around.

Once the word was out on what they were actually doing, the *company tuners* got real quiet.

Then there are those that have unofficial links to like GM, and get insider info., ie the how's and wherefores of what to do and how to do it. Since OBDII, it's become an insiders game, unless you have lots of money.

What's surprised me is the lack of community effort hac'ing efforts. There is just so much that can be done, yet, things seem to be on a hold pattern for some reason.

 

Yes, very well stated.

RBob.

 

that would explain a few things......

 

Do you mean that we are on a hold pattern with regard to hacking new code ... or, are you referring to something specific with regard to the older code like AUJP?

With what can be done.
While the GM code is good, there is lots of room for improvement, IMO. I've been privy to running some stripped down basic code, and it brings things to a whole new level.

In the years that so many hac's have been available, there has been little to no real refinement or developement of it. While there are a 1,000 times more guys prom tuning, few really want to contribute in pushing things forward. Yes, there are some, and it seems it's the same few, that have done the heavy lifting since day one.

It would just seem like with a bit more participation of people willing to contribute, even a little that we could be doing alot more.

 

Understood. BTW, maybe this is a catch 22? We have tons more people programming PROMs. Thus, we have tons more people doing it for Profit since the info is readily available. Maybe this makes people shy away from spending tons of time on rewriting stuff, refining stuff ... when they know that some loser is just going to steal it and use it for profit?

IMHO, I wouldn't even consider doing this type of thing unless it was on a private message board where you know all the players. As an example - I reworked my AFR program. It now completely inserts Mike Davis' Wide Band Hac (and removes it) from any BIN. It also has my famous (or is that infamous) modification of the PE tables ($8D and $6E only) via an AFR grid. It works great and is a very compact program. This program is awesome for dyno tuning. Insert hac. Run on dyno. Tune the WOT AFRs. Remove Hac. Done. I've given it to a select few people (who aren't even really on this board). I won't distribute it to the public because it's too easy for some greedy person to make money off of my research and hard work. Kudos to people like Mangus (i.e. TunerPro Editor) who still distribute their stuff for free. But, when you have something that nobody else has (and that something has proven to be incredibly useful and valuable), then you tend not to distribute it to the public. Who knows, maybe I'll change my mind and make it publicly available. Could happen. People like Mangus inspire me to be more optimistic and giving

It really is a shame that some people ruin it for the rest of us, like me who can rough in a bin and get decient results.

However, the code stuff is way over my head at this point, even after 1 year of studying how to burn/edit and programs like the ones that tim is talking about I think would greatly aid people in the same boat.

...what ever happened to the honor system.. If some one asks you not to use it for a different purpose, you dont!

In the long run it hurts all of us "grunts" who know enough to basically get the job done, but all of the fine detail stuff we sort of get a bit lost on.

PS. Tim, Please at least consider making the stuff available to those like me who are good to their word!

 

What can I do to help? I don't know assembly lanuage. So what am I really good for?? If you really think I could help then give me a task. I'm willing to throw away countless hours...

 

I guess you guys have seen the web page, "my day with SDI'.? I about died when that jojo guy suggested that rbob needs(or used) SDI for a prom chip. remember that??

It's not hard to keep your work safe from "leaches". If you put something unique in the code there will be legal proof to your claim.....
