This is a service fee to check out your improperly operating ECU. I will check over your ECU and test it out to verify the problems you let me know it is having.
If the ECU is easily repairable there will be no extra fee required except return shipping to you. I will repair the ECU and notify you when it is ready to be shipped back.
If the ECU is not easily repairable or completely fried, I will notify you immediately and go over what next steps can be taken.
To be clear, this fee is to check your ECU and make simple repairs ONLY.
