yes the narrowband voltage is right, i verified with a volt meter.

I did disable open loop, increased the maps by 1% all the way up to a 12AFR at idle, then went up 1 more % and it jumped up to 19AFR. Im gonna try to hook the stock o2 back up.</TD></TR></TABLE>

somethings not right here. Is your engine properly warmed up when making adjustments? Closed loop disabled checked? are you changing the correct columns for idle? Can you verify with datalogging? 1% change in vaccum doesn't cahnge much since your values are so low to begin with. corrupted bin? CELS? ...the more you give us info the better chance we can help you out

 

here is the latest update.
I put the stock 240s back in

I have 3 ecus

jdm p72 unchipped
usdm p72 chipped
and a p75 unchipped

I burnt a base map with uberdata for the p72 and it ran like crap. I hooked up the other ecu's and it ran the same way. All of them throwing cel 1. I then hooked the o2 sensor back up but didnt put it in the cat. I ran the narrow band wire (gray) from the wideband unit to the white wire on the stock o2 sensor. Tried all 3 ecus again and the same result with the same cel.

At that point I pulled out the multimeter and checked to make sure it was the same voltage at the end of the gray wire (at the stock o2) and then checked the voltage of the wire going into pin d14 on my ecu and they were the exact same. So the heating element should be warming up the stock o2 and the wideband is feeding the signal to the ecu. I have no clue what to do next.

When the stock ecus are in the AFR is less the 10.

I would like to get it running without the help of open loop in uberdata.


maybe my crower stage 2 turbo cams are messing it up???

After this i just said screw it and hooked up the o2 alltogether and im still throwing the cel, then I swapped that o2 with another and still throwing it.

 

This is easy. Throwing code 1 means that either your ECU has been chipped incorrectly or your map is bad. Try running a completely stock GSR map, if you have a GSR, or LS map (import the LS MAP!!!!!) if you have an LS. Burn the bin again and try again. Do you get a CEL with the unchipped ECU? If so, I would look at wiring issues here, because this seems to be a bit more serious.

tried running it on the unchipped ecu and it throw a cel 1 aswell. Even after hooking the stock o2 backup.

its a b16 I imported the p30. The chipped ecu is good, worked on a friends car.

oh, just to let you know, the wiring harness has been swapped, is currently a b16 harness, was an obd1 ls harness. Both of them threw the cel 1. SOOOO do you think it could be wiring inside the car, maybe something shorted out??? Would the short cause all these problems?

 

I'm willing to bet what's left on my paypal account that's it;s the harness j/k

Yeah look into that I think everyone that's still readig this would agree....get a volt meter and start checking or borrow someones if you can find one

Hey before this goes further I just want to thank you for your input through out the day! im pulling my hair out over here!!!

ok, back to the subject at hang.

I swapped the harness out 2 days ago. and it was doing the same thing on the other one. I do agree that it must be a wiring problem though.

I looked at the wiring diagram, and the signal wire (white/red) goes straight to the ecu. I checked voltage on this at its good.
The heater unit is disabled in uber so I dont have to worry about the two black wires. But the Green wire goes to the TPS and then to the ecu.

If their is a short somewhere I think its has to be the wiring harness inside the car. NOW THAT WOULD SUCK.

 

well i figured out what it was, the timing was way off. The cam gears didnt line up hardly at all, like 2-3 teeth off. But its fixed and running soooo smooth
