Hondata

ok heres the deal,
I have the s300 installed in a p28.
I have the innovate lc1 installed and wired up as shown ( PLX wiring ).
First started up the vehicle and it was running and reading fine.
After 30 mins, the car stalled. Now everytime i start up the vehicle af
reading is at 7.35 then jump to 22.XX and it keeps going back and forth.
The car will only run for 5 seconds.
If i switch the ecu to closed loop, the car idles fine, but af reading stays
at 7.35.
Switch it back to open loop and the car wont idle again.

What could be the problem?

If you remove the LC1 does the problem go away? IF so, then it is probably a problem withteh LC1. We do nto recommend the use of the LC1 as they tend to be very troublesome. We ONLY recommend the PLX.

^^
ok so i disconnected the lc1 and changed the setup to run off the stock o2
sensor. The car now idles, but just idles like crap, needs to be tuned.

another question, in open loop the idle bounces around a bit 800-1000 rpm and looking at the vacuum gauge the reading is around 15, once i switch over to closed loop the car idles fine with vacuum of 20.

Is this just the calibration that is causing this?

This is only a base map im running off of right now, just trying to get a clean base map so i can get my car over to the dyno.

I would get the car to a tuner as soon as possible and get it tuned...that will probably solve most of your issues unless you have mechanical/wiring problems somewhere.
