It is not neccessary as the ECU will still adapt over a period of 5-10 drive cycles. Resetting the ECU after a mod will force the ECU to learn and adapt in a much shorter period of time. Instead of disconnecting the battery terminal, you can reset the ECU in car without touching the battery with this technique:

Read the process a few times before you try to do this its ALL ABOUT TIMING:

1) With the key in your pocket/car, push the Engine Start button TWICE (so the car is fully on, but not started)
2) Within three seconds of the car "ON" (again NOT started), Floor (all the way down) and Release the gas pedal fully 5 times within 5 seconds. Do not do this too fast.. 1..2..3..4..5
3) Wait 7 seconds then floor the gas pedal and hold for 10 seconds. After that 10 seconds the Check Engine Light will start to blink slowly.
4) Release the pedal and floor it down once again and hold for 10 seconds. After these 10 seconds the check engine light will disappear then begin to flash much more rapidly. After you have done the following turn the car off and then back on. The ECU is now reset!!
