Message: [QUOTE="Charles, post: 1317234, member: 103"] The whole lebbentybillion PCM's doing the same job thing really pisses me off. Ask any one of them, what do you do.... Well, I run a 7.3 powerstroke diesel. And I have 5 million lines of code for transmission control. Uh, hum.... so, why are there so many of you? Oh..... because we like to overcomplicate everything to the 16th power. That's also why we like to make maps that look like we shot a hydra-shok round into jello... Fwiw, there's supposed to be some kind of alternator charging issue if I were to say, slap a DAC3 PCM into my 02 truck. But funny story, true story.... if you [i]actually[/i] look at the PCM pinouts, there the SAME! So if something is going astray, it must be INSIDE the damn thing, or..... more likely..... just in the software/firmware. I actually contemplated flashing an AEB file onto a DAC PCM I had. Or...... cutting the part of the calibration I actually change out of the hex and pasting it into an otherwise DAC file and loading that onto a DAC PCM. Or, as much or as little as it took to get the actual calibration I wanted on the thing with as much of the bullllllllllllllllllllllllsh*t that tells it to F up the alternator un F'ed as needed. I think the whole thing is a circle ***. I don't think it's ACTUALLY happening. I think it's what happens when your phone gets locked out of apps because of your operating system. There's not [i]actually[/i] a good reason for it, but the software [i]says[/i] no. Just like having to spoof windows 7/vista as windows xp to get a program to STFU and load. And then low and behold, there wasn't anything wrong in the first place. Why do I get the feeling international trucks don't have this many different PCM's from 1994 to 2003? It's like..... well, the xxxxx pcm looks for the MFD table from address xxxx to xxxx and the yyyyy pcm looks for it from address yyyy to yyyy, so they don't work.... And I'm like..... well..... the SOFTWARE tells the damn thing WHERE to look for the DAMN HEX!!! While we're in there CHANGING the SOFTWARE, why don't we bother to mention WHERE we have placed the damn MAP in the hex?????? So ford changed a baro sensor. Turn that thing off right from the start, lol. Sorry for the rant, the damn 4000 pcms to do one freakin job deal has run it's course. Why can't we un*** that? Or...... are all these pcm's just BEGGING for us to tell them WHERE to look for all these maps and we're just NOT doing it??? Do we need to have somebody like swamps just swap any and all non-standard internal parts to a unified standard for a fee, and then everybody can just run A pcm from now on? A cache code, A template. Doesn't matter if it's auto or manual, or if you happen to like a different radio station or toyos vs nittos??? Just one? Would it really be that hard? Again, are they ACTUALLY different? And HOW??? I have a low tolerance for things that have NO purpose. If a put a p-7100 on anything from 1994 to 2003 they would all run EXACTLY the same. Because it's the SAME ENGINE! Does this not occur to anyone? I have run engines of all vintages with no change to anything. Even though these engines came out of trucks with all of these "special" pcm codes that are just so wildly different that nothing will ever work, yada, yada, yada. Plug in, crank, BRAP..... running like a top. All this PCM code mess is a bunch of prima donna crap. Somehow we let the dog wag the tail on that one. There's nothing special about these PCM's. I think 90% of it is just botched programming. Changing one portion of the code without updating the rest to make it aware of the new addresses. Can we not flash more than 224 or whatever? I feel like we're leaving most of the damn code untouched. Why? Why for instance, can we not alter the algorithm that governs idle control? Where's the part where we define HOW pedal voltage is mapped to MFD so that if we wanted, any pedal voltage above that which did not initiate the base idle function combined with a given engine rpm resulted in one, un, uno, 1 value for MFD? Like, I don't care if the truck is bouncing 10 feet in the air with a driveshaft flying through the bed, as long as voltage does not vary, you stay right on the MFD line for that voltage??? Instead it will jitter around, like it's got correction going on. Trying to maintain an actual mass of fuel, as opposed to the numercial value in the map. Anyway.... getting late, I'm rambling. One more..... bs..... LOL [/QUOTE]
