im running gsr with uberdata
for some reason my Wideband shows 21.0/1 when the engine is cold but goes back to normal when it warms up. it just started doing this. i am running the zeitronix wideband with a egt. is it uberdata or my wideband??

 

most widebands take 10-30 secs to heat up. is it within that time after you start your car?

how does your car idle during this condition?

 

mine also takes almost half a minute to give sensible readings, I have plx wideband

 

heater for the o2 sensor has to heat up to read right

 

no it takes until my car gets to normal operating temp like 10 min before it goesw to normal. the car idles fine and accelerates just like normal.

 

it may be going out. Mywideband sensor died on me about last week and it would just say LEAN when in boost. It was just acting very strange all of a sudden, but my car wasn't. I bought a new one and everything was fine. Has it been doing this from the start you had this? How many miles has the sensor been through. Any chance of fouling it...say running very rich for a while....SEAfoaming....oil ran through exhaust?

 

Is there a warm up fuel table?
