I have a Rn85 model hilux and recently swapped a sr20det from a s15, i got it running but idles at 2200rpm but i dont think its the issue with the idle control valvue unit. I have a haltech elite 1500 running with it does anyone have a insight on how to operate the haltech nsp software, i want to try fix it from there to idle at 900-800rpm. I have alot to fix up and the idle engine allows me see where my exhuast would leak.
