just recently installed a frank swap in my rsx runs lil rough i was wondering if lengthing my injector wires would cause my injector pulse width to go all out of wack?
k24a1/k20a2
k-tuned fuel rail
k-tuned tps
prb intake w/ short ram
stock header w/ 2.5 cat back
k-pro v3 up to date
any other sugestions to my build would be great thanks in advance

Re: injector pulse width inj/ms
You would of had to lengthen your wires by a could hundred feet for it to make an noticeable difference.
However if you did not lengthen them properly it could cause some resistance or impedance in the system.
Also I noticed that you are using a K20A2 tune for a K24/K20.
I would at least recommend getting a tune.
Also try relearning the idle, I noticed your idle control was really far to the right. Maybe its dirty. Take it off and clean it.
Just some ideas.

Re: injector pulse width inj/ms
Try the ECU in a known working vehicle. If the problem goes away then you know you have a wiring or mechanical issue in your vehicle that needs to be addressed.
Re: injector pulse width inj/ms
I have the same issue currently, I've have also changed all the parts as you mentioned as well. No change, I'm 100% sure its the engine harness, I have ordered on and will be here this week. And if its not that then its then ECU with may need to be sent in.
