How many screws do i have to pull to get loose the ecu, and does the ecu up grade give noticeable improvements

 

What year is your car?

 

its a 99 i30

 

remove the bolts holding down the ECU brakect and then remove the whole ECU with the bracket attached. I think there is just two 10mm or 12mm bolts twords the rear of the car. I can't remeber if there are two at the front or not.

Either way, it's kinda a PITA to do. I could never get the ECU back in totally correct with the bolts. But I got it back in there so that I could put back on the plastic side covers so someone could never tell it was removed.

 

You have a 99, there isn't an ECU out for your car :-(

 

Did not even think about that. Yhea, your SOL dude.
