ECU Replacement/Auto Tune
TMAX uses the Bosch LSU 4.2 wideband sensor. They have failed to give the utility for "free" air calibration of the O2 sensor. Overtime a TMAX with the uncalibrated sensor will tune itself out and the bike will run poorly. Ignition curves have always been an issue. The Daytona system will work and will allow for "free" air calibration. They have always had trouble with start-up and warm up and IAC function and control. Fuel control will be okay if the sensors are calibrated periodically. Ignition will be a problem without a dynamo.
S&S VFI with Auto Tune seems to work. Ignition is an issue. Warm up and start up when cold is a little problematic until the O2 sensors are warmed up and sending data. Rev Perf Performance takes your Delphi ECU, adds the wideband sensors and they change data settings in your ECU then you re-install. O2 sensors can be calibrated. There have been problems on the newer 2011 and 2012 bikes. Auto Tuning and sensor accuracy with all of these systems will be the issue.
