I thought you guys ran all 3 hi-octane maps with the same values?

my car sux when its cold too
Grrrrrr...... I was under the impression that #3 was a safety map. Maybe I shoudl think about making 1,2, and 3 identical.

nope - i've done some logs and all 3 maps get used fairly regularily.

either:
1) make the same changes to all three maps
2) make changes to #2 only as this is a common map that the ECU uses in making any timing calculation (when NOT in error condition)
3) make all 3 maps the same..

each has their own merits, none is more right or wrong.

Although you have to wonder why there are 3 maps in the first place... Mitsu must have some inside info we dont know yet :P
