need some help here...been tru a lot of forums and no clear answer at all...do h22a4 injectors use a resistor box? half the people say yes and the rest no...im in process of h22a4 swap into a crx...

 

H22a4 injectors are high impedance, no resistor box.

 

Also as a last check if you are not 100% sure of the source of the injectors, you can measure the resistance between the posts of the injectors. Around a 3 ohm resistance means low impedance, a reading around 12 ohms means high impedance

 

Ok got it. So no resistor box. Ill eliminate it today since i been having low idle problems. Would this be the reason on why motor turns on and kinda bogs downs on lower rpms? Btw im using a p28.

 

Yeah I would imagine it would interfere and I also believe I had read that it would somewhere. In theory it should. I had recently posted almost this same exact question about a week ago and it got moved to engine management. I am also having rough idle issues with my car on my chipped p28 in my 01 lude h22a4, I think it has to do with the tune though. I have contacted the company I got my basemap from and they are sensing me a tweaked basemap to see if it improves idle, my idle is very lopey, bounces consistently from 600 to 900 rpm and if I give it throttle and let off it dies.

 

Huge difference, removed resistor box and ran smoothly. finally got to test drive it a little bit, but now there is lag on the throttle response...
