How long is a piece of string? It really depends on your driving...but 70ks is ridiculous for 17l
Evo 5 doing only 70kms average with 17 Litres 98

Sorry lol don't understand most of this narrow band and wideband stuff. So aslong as the gauge reads 14.7 it's got a good air/fuel ratio? Can I just use one of these gauges at http://www.trademe.co.nz/motors/car-parts-accessories/performance/gauges/auction-682209243.htm ?

That is just a gauge. No sensor and no controller. Mtx is what I said:
https://touch.trademe.co.nz/login?return=%2Fsearch%2Fsearch_string%3Dinnovate%2520mtx
Cheaper on ebay tho.
But I cant remember if it will output a narrowband. It has 2 analog outputs. I think thats what they are for.
This is only a tuning aid. If you dont know what wide and narrowband are then its not going to do much good having it. Google wideband and narrowband. Then google AFR if you read about it in wideband and dont know what it is.
It should read 14.7 at idle, cruise and slight acceleration. More acceleration will see the number lower and full power will see it around 11.5 or so.

Yeah the innovate will simulate a narrow band signal to the ecu. So yeah probably the best option. At least you will know what your afr are.

The one that Jack linked do not output the correct output voltage so will not "talk" to the ecu. You need one that has a narrowband output like an Innovate LC1 which you can then use in place of the factory o2 sensor. If you use the one Jack linked you will need to weld a new bung in the exhaust AND replace the factory sensor. The LC1 is the go and will be the cheapest option.

Sorry jamo. I had to have a look, it was bugging me. Innovate have the manual on pdf. And from the manual:
4. Optionally, the YELLOW (Analog out 1) and/or BROWN (Analog out 2) can be connected to the analog inputs of other devices such as data loggers or ECUs. If either one or both of these wires are not being used isolate and tape the wire(s) out of the way. The default analog outputs are as follows: Analog output one (yellow) is 0V = 7.35 AFR and 5V = 22.39 AFR. Analog output two (brown) is 1.1V = 14 AFR and .1V = 15 AFR. This is a simulated narrowband signal.
So, brown is the go. Go the brown.

Wouldn't a dyno show the AFR to see what they currently are? Although might be pointless spending money on a dyno just to see that?

lefty putting on a dyno will be a good way of checking more than just the AFR's you can see the true boost levels where its comming in you peak power and torque levels etc and that just from a 3 power run booking ~120 bucks here in aus if you don't visit on a club organized dyno day.
being a road tune i'd be willing to bet it was set uber rich so as to not risk detonation. if it was me i'd put it on a dyno and then speak to the tuner about getting it set up beter

Had it scanned again and again shows no errors all checks out fine via sensors. Was told to check spark plugs etc. Yeah could be the way it's tuned, dyno tunes are quite expensive here around $900.

Thy arnt much better here I've been told 700 or ~250/hr to tune a haltech.

Thats why I was saying the mtx may suit. It is a new o2 sensor, will check your afr and give you a readout all the time and is cheaper than either a dyno run and genuine narrowband
Just to confirm, so I dont buy the wrong item, and the Innovate MTX L linked below will give me the correct signal for narrow band to send to the ecu if I use the brown output? Im currently averaging 250 - 300kms from a tank of 98 on a SSG RVR. Filling up just before empty. Its making the landcruiser I sold look good on fuel now.

I had issues with my first one and was glad I used a seller in my country so we could sort it out quickly. (New replacement)

Get someone who knows what they're doing to check over your car for you.

My car seems to not be pulling as hard as it used to when I first bought it. Could this be apart of the oxygen sensors needing replacement? Gauge hits 22psi so not sure what's up.
