Will installing DSM 450cc Injectors cause a problem with a Stock ECU in a Ls/Vtec???
 
Yep youll be needing a tune after installing them because the will give the motor way too much fuel.
 
Depends on the year integra as well. You'll need to wire in a resistor box if it's an OBD1 or newer (if I remember right).

And yes, you'll need a tune (of sorts). Most tuning programs have a multiplier value that can modify all the fuel maps based on a larger injector size. So no, like, 'tuning' is required sorta. Crome, Hondata...something like those will do ya.
 
ANY change away from stock injectors. Why are you changing them then? 240cc is stock. Make ANY deviation from that, and you need to get your ecu recalibrated.
