Also how many people actually had improvement in the condition from shining the sensors alone?
Those who have swapped the ECU’s or reflashed, how do you figure out to swap the proper ecu into your car is it just matching year and transmission or are there codes i can find, if so where/how?
As far as reflashing does ecutek have the software and can i load it that way or do i need to visit a dealer and pay them for the flash?
