Tuning options for Dodge Mopar

[RobertISaar]

i can make decent assumptions, but beyond that, with no solid information on anything in the calibration, that's pretty much all they are until they're tested on a real-world vehicle.

How does the 2d and 3d data viewer help to do this in TunerPro?

i don't use it..... i actually have a french program to look at stuff in raw values, displays the actual values, along with color coded cells, easily allows you two switch between various bit lengths, etc....

but the basic principle is the same, open up a BIN with it, look for patterns, move the viewer around at suspect addresses, try to make a table come out of seemingly nothing by adjusting the start point, bit depth and row/column count.

when you do positively ID a few tables(preferably a few of 2D and a few 3D), you can then go into the disassembly and see where they're referenced, and more importantly, the subroutine used to look up the value from a table. then since you know what subroutine is used for the table, you can then find all the places in the code that jump to that subroutine and you'll find pretty much all of the tables, unless they use a different lookup subroutine. GM OBD1 calibrations use between ~2 and ~5 2D lookup subroutines depending on how complex the program is, 3D lookups.... usually 1, sometimes 2.

and that's how you find most of the tables.... now to figure out what they do and why they're used... that's the hard part.
