Re: spark advance table
The data is sometimes listed in [hex] 0-F (16 digits) not [dec] 0-9 (10 digits), then the software (Tuner Pro) can covert it (0.351567 * X) to engineering units like degrees.
TP uses [hex] or [dec] (interger) without a conversion, this is setup in the XDF.
(.351567 * 61 [dec] = 21.4)
(.351567 * 92 [dec] = 32.3)
(.351567 * 97 [dec] = 34.1)
(5C [hex] = 92 [dec])
(61 [hex] = 97 [dec])
