You can also use SD and live mapping to start up a brand new engine that has never used a MAF if watch the lambda and trims and adjust the injector size to suit. You can preprogram your fuel map to your desired AFRs and then balance injector size and VE to make it happen, based around a 100% midrange VE. It has even been done without live mapping.
I had a Subaru to map last week. It had a misreading MAF sensor due to APS CAI, and injectors, it was also maxxing out the MAF sensor. I would have killed to have SD and live map like on the Evo for that. It took 5 hours when 30 minutes would have dialled it on an the Evo.

I see. Thanks for the explaination. It is how I had initially thought. If you add on some mod to your car then there would theoretically be places where your AFR strays from what's in your ROM's map.
So the idea behind the initial MAF to SD routine is so that you don't start off with values that will get you 14.0 AFR under boost, for example... it seems. (I still have yet to setup SD on my car, but am very eager to).

Well, John did it, and I just copied his work. 
But yes, you should be able to adjust the alternate boost maps as well; there's just no obvious interface for it in the client. You'd have to make your changes in the ROM with EcuFlash, save them to disk, then push them with the client; it's a little dodgier, but it should work.
Ideally, of course, someone would add support for those addresses to the client.
Just for the record, the full list of alternate maps (from my post alone, l2r's post above adds the SD stuff as well) that are usable in RAM are injector scaling, high-octane fuel, high-octane timing, BWGDC, and BDEL (the last two should be sufficient for both load-based and PSI-based boost control, in case anyone is wondering). Technically, everything between 3B700 and 3BEFF in the ROM (ie. most of tephra's stuff) is copied to RAM, but that's only half the battle; you then have to change code to reference the new RAM addresses rather than ROM, and for quite a lot of stuff in there, it's really not worth the trouble and added complexity.

Hey guys....I just edited post #2 above the livemap step #6. I tested writing to RAM today and it wasn't working. I think I may have missed something in the LiveMap config, since this latest release was initially setup for the 885 ROM. I will go through everything and find what I need to update and update post #2, if necessary.
If I can, I will just compile a new LiveMap app with all of the XML files already setup for you.

If you end up at the S.O. you will have beers on me for this..!
I'm wondering about the SD stuff though, I have everything on the car needed to run it. But I haven't had a MAF on this car in almost 2 years now... Having airflow #'s and temps constantly fudged by the maft-pro is getting OLD. Like... Yeah ok ecu... I'm at 260 load at 28psi on a 3076R ... no. I can flow 360g/s at 260 load? I was just tuning another 05 with the stock turbo and about 19psi ---taper--> and he's hitting 250-260 load. at 250g/s...
How bad is it going to be to fudge my way through this without a MAF / live mapping?
Or am I just going to hit load limits and have to rescale things... a lot.

OK, I need someone to host the new LiveMap app. I am still working on it, but I compiled a new one, with charting. Also, I noticed that the ms in the logging isn't in this source code I have. So, I am going to add that as well. I'm about to sit down now and figure out the ram writing issue.
So, when I am done with all of this, who can host it for me? The files zipped up are going to be just too big to post here.

I just remembered that my ISP (comcast) gives hosting space. I forgot that I set that up a while back. So, once I finish the new LiveMap app, I will give the put it there and post the download link.

Eric, just fyi: if you end up needing space to share stuff like that, you can always put it up on the wiki somewhere. It's not the most convenient place to host that kind of thing (mediawiki's file management support, frankly, sucks), but it's there if we need it.
