well i have an innovate wideband lc-1 with xd-16 gauge had it for about 1 year.. at idle it used to read 14.5 to 15.0 normaly it was on 14.7

at WOT it would read 11.2 to 10.9 at redline.

now just the other day it started to go nuts. at idle im reading from 20.5 to 26.0

at WOT it is reading 18.0 to 20.0

car runs and pulls fine.

i called innovate motorsports and they try'd to help me out.
here are the steps i took
when it started i recalibrated the wideband. did not help
i called innovate and they had me recal it again a few other ways still did not work
i got a new sensor and recalibrated it again. still did not work
then innovate said to get i lighter and hold the button down so the fluid would come out ant put it by the sensor. which i did and the new reading was 14.1 they said it was something with the car. the wideband is fine.

so this is where i stand.
no exhaust leaks
i look'd at my fpr and its all conect'ed right.

anyone else help me here. im afraid to drive the car.

 

anyone?

 

ok again i reset the ecu
recalibrated the wideband with new sensor
i replaced the line on the fpr. still no change.

anyone?

 

check for leaks around the intake pipe. If there are any leaks along the path of the filter to the turbo, it will result in a lean mixture (unmetered air is getting sucked in). Also check your fuel pressure.

 

ok im going right now to check the intake. how do i check fuel pressure on the stock system??

 

Exhaust leak? bad sensor?

 

Your going to have to be creative with the fuel pressure check...make sure you measure it off the fuel rail, you will have to buy a gauge of some sort. If you can't figure it out, you will have to take it to the dealership for that. Definitely sounds like it might be some sort of fuel problem though, maybe your pump is clogged or is dying?

 

no no

 

ok i check'd the hole intake on the car. i even took it off reinstalled it and everything was fine. but the car is still messed up

as for the fuel pressure just wondering
wouldent it afect the cars driveability? i mean if its hurting for fuel it should show up on the way the car act's. it ilde's fine and when im driveing it is fine. even when i WOT it it is perfectly fine. its just my reading are going nuts.

is there any vacume leaks i can check for? fpr is already check'd egr valve was check'd all them little rubber hose's from the trottle body and the one's below where check'd as well. i dont know where or what to do now.

 

Where is your boost gauge teed into?

 

it is tee'd into the fpr. BUT i already put a new 5 inch line on the fpr to see maby if my boost line into the car was leaking. i did not have a leak. when i changed the line i again recal'd the wideband and again. nothing.

 

i cant see how the car would even run at 20-26 afr, you gotta be getting air into your exhaust somewhere if the wideband is for sure working, did you try hooking it up to another car?

 

no. im going to do that this weekend. i just need a car to do it in. one of my friends will let me do it. i will report back then.

 

I had the same exact issue with my LC-1 as well....i even sent it in for testing and everything came back normal...they recommended that i ground straight to the battery/engine because the ground on the LC-1 is kind of picky.

 

well i will reground it right to the battery. i will try it .
