Default 450 Injector Trouble

Ok I can't seem to get the injectors to work correctly.

I've got an OBD-1 B16a3

Did I wire them correctly? Maybe I wired a power wire to my ECU? :eek !!
My car gives the ECU fried code...1 steady CEL....and doesn't rev past 5600-5800...

Maybe I'm not using uberdata correctly?
I opened stockGSR.bin.....went to Import P30....selected P30.bin....and changed the injectors to 450cc.

This is how I did it.

check your fuse box under the hood. This happened on a friends car when we were installing his injectors and it turned out that a fuse was blown.

maybe your fuel injectors are stuck... hapened to me. I guess they werent running in a car for over a year so the varnish got to them. So, i soaked them in gas and directly wired them to the battery to jolt them open. Seemed to work because before the car wouldnt start and after i did ive been boosting since I know the injectors were the problem because i changed back to 240cc to make sure it was the problem. Check your plugs to see if they are wet with gas or not.

correct wiring:

except the 'from ecu' part should really read 'from power source'

i just installed my 390's with inline resistors and am getting the solid cel as well. I'm pretty sure mines wired right since it's pretty damn simple. I burned a new map scaled for the 390's but I must of missed somthing I'll check it out tomorrow
