Hi I just intalled a lc-1, but my stock o2 was dead so I put the lc-1 in stock bung and am running the narrow band emulator to my stock ecunow my car has spurts where it has serious lag until 4500 rpm(vvt area) and rough idle im thinking maybe I need to alter the programming of the narrowband output anyone had any experience with this problem maybe someone can tell me optimal a/f ratio for a naturally aspirated 1.8 thanks.

 

You need a new stock O2. The LC-1 sensor won't like the heat where you've put it.

LC-1 Manual here.

Which color wire from the LC-1 did you connect to your engine harness? Which color wire in the harness did you connect it to?

Did you calibrate the LC-1? Do you have a wideband gauge installed reading off of the LC-1, and is it working?


Edit: also, note that if you expect many responses in this thread past this one, you should really work on cleaning up your posts. My 2nd grader (seriously) can write with better grammar than you are using.

 

I was going to reply but I can't read endless run-on sentences like that.
