is it possible?

I have an ls and I believe that my ecu is shot. Some1 said that its possible 2 use a gsr or si ecu and it would give me better air/fuel ratio. I would think that it would b useless or would mess up something else bcuz I have no vtec. Any info would b appreciated!

1)how you know your ecu is shot?? if you are unshure you should atleast check for pulse on the injectors that the easiest way to check. 2)vtec ecus on non-vtec motor run real sluggish.

its a bad idea, there 2 completely different engines with 2 completely diff air/fuel maps

Yeah...running an ecu meant for high compression engines are totally different of that of an LS since LS engines are low compression...different base maps will cause ************ty running conditions and spell no good for your motor.

x2^

why do you think the ecu is shot?

I'm not getn any spark and I changed the dizzy and the coil. and the 1 fuse that was blown I changed.

check for an exposed wire in your harness! and look for bad grounds!
