it may just be a tune like he said. when loading a stock map in a not stock steup is going to cause issues with idling and drivability. i say get it tuned, and go from there if you still have an issue you can at least rule out the tune which is a major factor in any build.

What exactly does "not idling" mean? Hunting...bouncing...stalls?

Did you go through the process of setting the idle? Open up hondata help and search for "idle" and read the section "Idle Speed". Follow that process. Once done with that then you can fiddle with the idle using the iacv duty cycle slider on your hondata "Idle" tab in parameters. Also, if you get warm stall symptoms check the box under "Misc" in hondata that says "invert purge valve".

Just follow the hondata help that I mentioned, that should help get it squared away.

Oh, also confirm your o2 sensor is working, that will also screw with your idle if it's bad.

I assume you changed the calibration to use the right fuel injector size? Tuning the idle will help but you need to get the basics done first, which is following that set idle process in hondata help. A base map *should* idle your car fine assuming it's setup for the right injector size (unless maybe you're using like 1600cc injectors?). My car idle'd fine on 1000cc's on a base map, but I made sure to go through that idle set process first and make sure it was all right.

Good luck.

If your asking if your low compression can cause problems with idle the answer is NO, 8.3:1 right here its kind of hard to tell what your question is between your title and what you said in the first post.
