***ECUFlash Now For Base Lancers!***
Everyone is still a bit hazy on this new development with maps, ROMs, META data files, etc. Here's the overview (please feel free to correct my errors):
You read your ROM data of off your ECU. This data is then converted into readable data via a META data file. The META data file has all the addresses and ranges where data is listed for each parameter. Once the data is readable and you can view all the available parameters you have a map. This would be considered a base map since it is right off of your ECU and no changes have been made. From there you can alter the data as you see fit. Everyone will have a unique map if tuned to as close to perfection as possible. This is due to engine mods, weather, mileage on engine, various factors. No one map will be for everyone. You can use a map from someone that has the same mods as you, but you will have to tweak it ever so slightly to your engine's unique characteristics.

Sorry, I had to
I"ll bring 
and chicks...
u seem to be on the right track. 
and chicks...

I spent hours last night looking over all the data at various addresses trying to find the ranges I need for my ROM file. There are quite a few just for RPM ranges alone. The data for the high/low fuel maps and high/low ignition maps were good. The ranges for them wasn't correct. The rpm limit also read as 7750 (I think). Close, but not quite It's just gonna take some time to figure out all the ranges for the different ROMs out there.

...by a pro? They might be professionals with working and repairing a car. But i'm not sure performance tuning falls into their job descriptions. I would never let them touch my ECU. If the world ended and I had to choose between a dealership tuning my ECU and a cockroach...well, you get the idea.
THe dealership as i've come to realize it knows less than we do most of the time. They just open books and say ok it says to do this, so lets do that.
Basic Idiots guide to ECU Flashes - Your ECU is basically just a big computer with a small harddrive. On that hard drive it holds a file which the computer looks at to calculate what it should be doing at any point during driving. This is the ROM. The file that we want to change so the computer will tell the engine to do what we want. We use the cable and the OpenECU programs to copy that file from our car's computer onto our home PCs. Then using conversion software our computers turn that file into a format that can be read on the computer. We then open it up, and change the things that we want to change in order to compensate for modifications. Once we have a "Map" (basically an excel table that tells the computer "at this point, do this") that we like and we think will work for what we are looking to do, we can then save it, and using the cable again, we can overwrite the file that is on the car's ECU. Kind of like updating an excel file in windows. It overwrites the old one with the new data. Thats why its important to save the "base map" which is the first time you downloaded it to your computer from the ECU, this is the map that the car originally came with.
And Beers, chicks, and cars, what more could you want?

You think it's possible, this is a theory.....
Have the piggy installed on the ecu... Then use the ECUFLASH to extract the rom and see how it looks up on the ECUflash prog? It might not even work, but just to see how the rrm pb is actually influencing our ecu..?
whatever.lol
