Innovative Wide Band Sensor, Not Working?

[Dan_J]

so i've got an Innovative wide band sensor and gauge to suit ( basic option ), i've set it up, calibrated it and its been working fine for 3-4 months, although now i'm getting random readings through out the air fuel ratio.

the gauge might display correctly for a little bit then will hunt from 8 to 22.1 and get stuck on 22.1 until the car is restarted and no the car doesnt lean out and stall when this happens.

i took out the sensor from the dump pipe and re-calibrated it which only fixed it momentarily and the problem came back after a day or two.

i'd like to know people's thoughts/ ideas on this issue ?

How far from the turbo outlet is the sensor?

If you have a laptop and cable try reprogramming it through LM programmer. Also check all your earth wires to it are secure.

just on the factory bung atm so right next to turbo outlet , will weld a bung at the end of the front pipe when i get round to it.

dont see how that could be a major problem as a few new cars run wideband from factory

i only re-calibrated the sensor by removing it and unpluging as the procedure, will try it through the laptop setup as i did a few months ago

I thought you had to tell it you were doing free air calibration but im no innovate expert

I would put the bung in pre cat (as per the installation manuals reccomendations) and go from there. You may need to buy a new sensor, for the money they cost and the peace of mind will be well worth it.

I know innovates had some issues a few years ago but cant remember if it was a problem with the sensor or the rest of the system. Dont think this is the issur but thought it was worth mentioning.

Too hot too close to the turbo. It could be getting upset and throwing the controller into a panic/confusion. Modern OEM widebands are not necessarily that close to turbo outlets!

Innovate says to place the sensor at least 60cm downstream from the turbo. Its best to place it just before the cat (any closer to the turbo and you're under the passenger footwell). There is a bit more of a cavity in the body around the cat area. It can be very tricky to get the exact angle, but you want it pointing as vertical as possible so that condensation doesn't sit in the sensor.

what firmware version is it running?

i found it had heaps of issues on V 1.24? or something. revert back to 1.0

Is this the Innovate MTX-L?

If so, I think there's an issue with the design of the gauge causing it to kill sensors. I'm on my 3rd gauge and 2nd sensor in under 2 years.

Not to mention the car doesn't get driven often.

I've read on evolutionm that the gauge overheats the heater inside the sensor causing premature death.. at the same time the gauge will often die too.

Luckily I bought mine through a local dealer (Game On Motorsports) so I had local support/warranty.

Sensor is too close, needs to be just before the cat. And need to be calibrated free to air.
