So need to fit a wideband sensor for better chooning of my WOT

Looking at the Innovate MTX-L here for £149

Anyone have these fitted and any feedback about them?

 

For those who've fitted one already what size bung did you use?

Peter/OBDTuner recommended a cool bung as the wide band sensors aren't up to handling the heat.

Looking at Innovates website there's mention of them coming standard with a 1inch bung, but not sure if that's enough.

I fitted one about 5 years ago (with the short bung) and it has worked fine. Install it near to the tail pipes, that way you wont get heat problems (I've not had any).

I use one to I used the bung which came with it which was the longer ones also no issues I think the important thing is position

[Bargi]

OK, so it doesn't matter where in the exhaust system it's mounted then?

Nev, think with the turbo's vs SC it's a bit like the exhaust noise. Turbo tends to absorb a lot of the noise and probably take a fair bit of heat out. (I could be wrong!), but still putting it further back sounds like a good idea.

 

Also seen these which look pretty good/cheap alternative.

It needs to be pre-cat if you're running one, or may run one, like the OEM "front" O2 sensor.

 

My local exhaust place supplied and welded a stainless boss for £10.

hmm, I replied and it vanished

 

anyhoooo, no need to close couple it. But do also keep it away from the cat as that will exotherm and radiate a fair bit of heat back up the exhaust (about 2" )

 

no need for dickish finned bosses etc.

I don't think you need the gauge - OBDT can display wideband data when the software is running. I think its wired into the redundant EGR wiring...

Is it worth taking the switched live from the fuel pump relay, which is only permanently on when the engine is running (apart from the short blip as the pump primes)? As I believe the wide bands don't like being switched on without the engine running.

I used the radio switched live but the important thing is to earth it from the ecu

This is true, but you can't have enough gauges

Worry dials

Beware that many of the Innovate controllers can be quite 'tempramental' and give all sorts of interesting issues with losing calibration on the sensor and such. You have to be VERY careful with Innovate units to make sure they are powered and grounded on the SAME points as the ECU.

 

If you don't need a gauge but just the wideband signal to feed to the ECU for datalogging then STACK do a unit that's very well regarded and solid: STACK ST994

 

PLX is also well known to do reliable stuff: http://www.plxdevice...?id=SEMOSMAFRV2

 

Bye, Arno.

I use it with 1" option and fitted near first lambda. No problems yet.

Calibrating your engine with an LC1 can be quite challenging and I hope they improved their product...

Bargi, it does matter where it is located, put it far down the exhaust pipe if you can, as that is where your exhaust gases will be least hot. the instructions when you buy one say that. I can't remember the instructions about placement in relation to the cat, sorry.

 

Calibrating them is a bit of a pain, as you should really get under the car, unscrew the senor out and expose it to pure air. You only really need to do this once a year or if you have suspicioins about accuracy.

 

It is a worthwhile tool if you are into modding maps or mechanicals that affect breathing. Knowing how your engine is "feeling" is always worth knowing IMO.

Innovative a did have a habit of eating Bosch sensors as they weren't quite to spec....hope that's changed

Don't say that!

 

Peter has been running an Innovate since last last year and he said it's been fine.

[slindborg]

They are fine if you understand they have limits and specific requirements for setup

don't be so Scuffers in your reply

is that a general comment or is there something specific you know that might apply?

[slindborg]

As Arno said, power and ground at the same place the ecu gets it from. And calibrate it in free air as often as you fancy.
