A kid I know said he is running DSM injectors without resistors or a box on his 00 SI. Then he showed them to me, so I know he isn't lying. Aren't Si's saturated too? He said he hasn't had any problems with them. Can anybody do this or is this a fluke?

 

yeah, they are saturated also. hrrrmmmmmmmm...... i don't know about that are you sure the were dsm 450's or some other kind of 450, or even 450's??

 

They either aren't DSM450's, He has a resistor box or resistors hidden somewhere, or he's a few days away from frying his injector drivers. Those are the only 3 possible scenarios.

 

If he is using 450cc injectors without resistors, keep us updated on his progress =)

 

ive heard of thenm working but you will burn up the injector drivers in your ecu. thats the whole purpose of the resistors

 

Yeah, you need resistors or the driver will see the injector as a 'short'. Since the impedence on DSM's is close to 3 ohms and your stocks are 12.8 a significant difference in current pull is evident. Eventually, you will overheat the driver circuitry by pulling 4 times the current through them and start to cry

Do it right the first time

 

I totally agree, I was shocked and awed when he popped the hood and showed me thos DSM's sitting there with no resistors. Apparently he's been running them like that for a couple months. It must be a fluke then.
