I have to drive around on my usdm b16 ecu until my conversion harness gets here, also so i can have the car legally inspected.

How safe is the tune on the b16 ecu? SHould i be driving like a grandma or can i get on it once in awhile?

 

1) not really safe

2) no you should not "get on it once in awhile", unless you want to take some of the life out of your motor.
