The ECU will adapt to everything, if it sees too much boost or knock, it will reduce timing, everygear, every rpm, if you start putting 87 gas or 91 arco in your car, you will be ok because the ECU can handle it for you

It is possible though, that the JB4 lets everything run stock until 4th and 5th gear, which could make that happen, but then you will have no power in 1st 2nd 3rd :\
