Autotune trim table shows all zeros

[shashankmittal]

This winter I installed a PCV with Autotune and a Yoshimura full exhaust.
I am using Dynojet's Akrapovic M12-012-503 map and my Autotune is enabled. I rode my bike for about 1000 miles after configuring the map, but I still see all zeros in the Autotune trim table. I tried another map (Dynojet's Arrow map M12-012-002), rode the bike for 600mi and the trim table did not populate with values.

Some screenshots:
Autotune is enabled...


Map fuel table...


Autotune's target AFR...


Autotune trim table shows all zeros...


The software shows me AFR value on the right and the status bar shows 2 devices connected. It makes me believe that Autotune is connected to the PCV properly, but I am not sure if it is working or not.

Something doesn't look right w/your AFR on the right of your screen. In a couple places is says 9.99 and another 0. It should not be saying either of these w/the bike running. It should be around 13.xx.

I'd check your wiring from your O2 sensor to the PCV/AutoTuner. There is also a test procedure you can do to check to ensure your O2 sensor is working properly... forgot the sequence, but you might look through the help documentation for it.

If none of that helps, get in touch with Dusty over at DynoJet (he's a member on the forum too).

Thanks, found it: http://www.powercommander.com/downlo...200/AT-200.pdf

It says that a value of 0 or 9.99 indicates a faulty O2 sensor. It also says that the O2 sensors are made by Bosch and are not covered under warranty! This is ridiculous...if I am purchasing a product from DJ (no matter who they source the parts from), they need to provide some kind of warranty.

Anyways, I'll test today and will post my findings...

I would say they have no case if they gave you a brand new item that does not work. They would surely replace.

O2 sensors are disposable; you can short one out in a week, or one can soldier on for three years. Think of them like light bulbs, but from brand new, you'd definitely expect it to work!!

O2 sensors do not like moisture; the angle which is required to mount them at primary has to do with minimizing condensation.

If youdo remove the O2 sensor, whilst you have it in your hand, please check and tell us what the specific model number is on the sensor. I may be worth knowing as I am pretty sure it will be cheaper to buy a replacement from a carparts store. In this case we would need the number.

Sure, I will...

Does this mean if the sensor is plugged into the exhaust...
1. I can't wash my bike?
2. I can't ride on wet roads?
3. What do I do when the moisture in the air condenses all over the bike on colder nights?

No. You should be ok once the thing is mounted to/inside the exhaust or cars and bikes all over the place would have a problem. In fact they are mounted at an angle to protect them from water directly at the tip re your question about condensate. No need to worry. What he meant is that if it got wet before it got to you it could have been damaged.

P.S. I looked on the Bosch site and it shows that DJ uses a few of the Bosch wideband sensors, hence my question about the part number.

What will shorten the life of a WB02?

1) Race Fuel with Lead .. which means most of them.
2) Not getting a good and strong voltage to the WB02
2) Moisture ... internally, like the kind that blows out the exhaust on a cold morning.

Also you can get false/bad readings because of an exhaust leak ....

Per boschautoparts.com:
An oxygen sensor can fail prematurely if it becomes contaminated with phosphorus from excessive oil consumption, silicone from internal coolant leaks, using silicone sealant in the engine, and some over-the-counter fuel additives. Even a small amount of poorly refined gasoline can kill an oxygen sensor. Environmental factors such as road splash, salt, oil, and dirt can also cause a sensor to fail, as can thermal shock, mechanical stress, or mishandling. However as required by vehicle manufacturers, Bosch sensors are designed and tested with these extremes in mind.
