No it won't, i thought issue was of calibration, but main issue was of plugs that I fitted, ngk laser iridiums misfire in this engine (not recommended) fitted original one again. The benefit I got from calibration is that my car wasn't doing engine brake on D, as deceleration sensor was off. They resetted it and its working now. Claimed warranty of recalibration of cvt through computer due to no reason as issue were misfiring plugs, but still beneficial as deceleration sensor is working now, when I brake hard at 80-100 it takes rpm all the way to 3000.
Toyota performs recalibration at every cvt oil change
