Question regarding tables.txt and VE table
« on: May 22, 2009, 09:02:24 pm »
A typical line in tables.txt for a 12x12 VE table looks like this:

j[0]=2F80 3080 3180 357F 337F 317F 377F 357F 357F 377F 377F 377F

Questions.

1. How do these numbers translate into real world values?  (For example, for the first value 2f80, are the 2f and 80 handled differently?)  What other scaling and/or translations makes them into easily interpretable values?

2. I assume that the j[0] is for the lowest kPa bin, and the values within the line relate to RPM bins?  Please confirm.

Thanks,

Ron

knock the second pair of numbers off each entry (IIRC they were something to do with VE autotune):
j[0]=2F 30 31 35 33 31 37 35 35 37 37 37

and convert from hex to decimal:
j[0]=47 48 49 53 51 49 55 53 53 55 55 55

Take a look in MegaTune and see how those numbers fit in with your 12x12 map.
