I’m running 404’s right now on my LS and need to raise the idle above 600-750rpm. Currently the only way I can have the car idle at +2 -2 is having the idle adjustment screw all the way out and it only idles at 600-750rpm. I spoke with a race experienced honda tuner locally and he suggested to drill out the TPS sensor and rebolt it in at an angle to fool the ECU into thinking the plate is in a different position that it actually is.
I removed the TB ready to do this and I noticed an allen screw/nut device epoxied in place (from the factory) which actually adjusts where the plate sits at zero throttle. Wouldn’t adjusting this so that the plate stays open a little more raise the idle since its exactly the same as me pressing on the gas a little bit? Maybe I’ll take some pics if you guys don’t know the screw I’m talking about. TIA

I just learned about this last week in my training! That screw shouldn’t be used for adjusting the idle because not only will you throw off the TP sensor but the IAC won’t be able to compensate when the ECU detects signals from other load sensors.

What exactly do you mean? How is this any different then me sitting in the car holding the throttle down 5mm? Is it because the ECU will freak out cause it’ll want to be idling?
Originally posted by BoyRaCeRs Just get a chipped ecu, mine idles at around 800-1000 rpms. or you can sdjust your throttle cable so it idles at whatever you want.
your chipped ecu raised the idle? i didn’t find anyone saying it did. my ecu is being chipped as we speak and while the car is out of commission i have the TB off and I’m trying to figure something out. What cams are you running?
I have a dinan ecu, my stock ecu idles at around 500 rpms but the this one idles near 1000 rpms for some reason. Before i was also running 404 cams. +2,-2 also. It worked well.
