 Why yes, they are :)

 What application??

 That much is easy, since you have the spark table ...

 Down is increasing RPM, and Across to the right is
 Increasing LOAD .. if you would be so kind as to post the
 28 bytes BEFORE this data for EACH table, I can tell you
 EXACTLY what RPMS, and LOAD values are for the sites!!

>Any help is welcome....

 Also, If you get me the code, I can tell you exactly how
 the internal table values relate to the real world for 
 spark and such ...

 The fuel map always has a BASE value of 128 (0x80) and is
 a multiplicative correction to LOAD to get the injection time

 In your engine.. LOAD must be calculated from MAP and RPM

 I can really help you more if you show me the actual code,
 in fact I can probably have it reversed for you in a few
 hours ... It's kind of a hobby with me :)
