I'll take map everyday thanks. Small extra cost if using djetro with it's annoyingly placed sensors, other ecu's not so bad there no need for throttles to come off.
Eliminates the need to upgrade afms later if power output increases, eliminates the problem of running like shit if a cooler pipe comes off, eliminates the problem of afms getting old and dirty etc. For mexicans like you it may be hard for defects or whatever but that's just life
Each to their own!
Btw jdm supras are all map from factory, another win for the 2J
