Wideband O2 meters.

I have been looking for a wideband O2 sensor now and damn they are pricey. I was looking at the Inovate motorsport LM-1 which looks damn good and fairly priced. It doe datalogging and all that stuff which is real cool for road tuning. Anyone else got or seen anything better??

Duane has a wideband thingy, that he tunes with, not sure what type he will give you low down.

Most of the tuning shop use the LM-1 as far as I know. Can get one for R3200 complete which is not that bad.

The LM-1 seems to be a fair unit allthough it has been slagged on some of the tuner forums.

Personally the next wide band meter I buy will be switchable between lambda and AFR. AFR is just not accurate enough when tuning big horsepower cars.

Well the LM-1 display both lambda and AFR at the same time.

What system do you use??[/quote]

PLX divices make nice wideband loggers too. Can log A/f, rpm, speed, and a few other stuff too, depending on the model you buy.

Look at the R-series

I have looked at the PLX R500 it looks pretty good and does egt's as well I am fitting one in that Sentra with all the gauges.
The Wide Band Commander from Dynojet is also a good one but has a analogue display it also does data loggi9ng etc

Was hoping to get it locally. I have read somewhere some of these O2 sensor datalog knock as well. That would be the perfect thing for dyno/road tuning because once your hear knock it far to late anyway.

i read somewhere on the vw owners club site for south africa, about two local guys who developed a lambda sensor, which also integrates a boost controller and something else.

it was going for R2200 or so, and even had a nice little digital module for readouts.

looked quite good.

and was local.

sorry cant remember the details now, but will try to find it.

I want something with local support. The innovate stuff has a few dealers here any the sensors are only R850 to replace.

try www.turbologix.co.za

It doesn't log unfortunatly

The Bosch LSU4 probe seems to have become the industry standard which is why it can be found for as little as R650.

The serious local meters I have seen all use 4 wire wide band sensors which afaik are not temperature compensated or calibrated or something like that.
The LSU4 is a 5 wire and has a trim resistor which has something to do with the calibration.
I am a bit fuzzy on that its been a while since I read about it.

There is a fair bit of info on Boschs website

Make sure that the unit can log at least rpm and throttle position preferably map as well.

Yip, I feel the same way about it. I have only got the R300 of the Plx but it's more than enough info for me, sad it doesn't have EGT though.
