i have an inquiry. i had this problem before and it was solved with a re-chipped ecu. however i notice something and would just like to know if its normal.

B16A motor. i know the oem ecu has a safety feature where the temperature of the engine has to be at the mid point, in order for the variable valve to work, correct?

so i have this ecu, that removes that safety feature because with my previous ecu, it was very difficult for me to engage my vtec.

i notice this: first few attempts, the vtec sound is rather soft, or rather, hardly noticeable. i have to rev it a few times (maybe 3-4 times) only then will i hear the vtec screaming like it should. is this normal? or do i have a problem with my vtec?
