ST185 Stock Fuel &
The following maps
are from the Japanese market Toyota Celica GT-Four ST185. The ignition
map is straight forward to understand, and show total timing (ie base timing
+ advance). The load sites of each map, are listed with Toyota's code instead
of an actual load measurement, such as psi, kpa, kgcm2, etc., so determining
the load sites requires estimation. Based upon the timing, I would estimate
that the "54F0" site is about 0 vacuum/boost, with the last site "5560"
being approximately 12.5 psi (0.86 bar). The fuel maps are done in hex
format, but George Betzos, a member of the GT-Four mailing list, was kind
enough to convert the fuel map to numerical format. As with the timing
map, the load sites are in Toyota's code, so once again, an estimation
would be required.
