Wideband O2 sensors, a few questions.

[JZA70 R]

agreed. everything you just said is stated clearly on the multiple installation and operation manuals provided with every kit. its pretty simple really.

[JZA70 R]

i mean, no way to possibly check if their sensor is actually correct... or say.. out by 0.5 or 1 AFR...
not many people have temp controlled gas rigs lying around...

so users might say "yeah it's grouse mouse" when it is actually reading wrong, but as long as it gives a number, they are happy

ie, not all driver circuits are good/great/ideal?

thats why its good to compare you wideband units output with others. dynos are usually a convienient and useful comparison.

[TurboRA28]

I've got a tech edge unit and love it, had no problems at all and tuned a good hand full of cars now.
Only problem I had was the 02 sensor cable broke from always been closed in doors/bonnets etc.
Peter sent me a new one which got lost in the mail, he was good enough to send another one at no expense.

main issues I've seen with LC1's is people dont follow instructions and install them incorrectly, you need a good power source and good grounding. On the innovative forums I also see people complaining about E8 errors on decel but I've not personally experienced this with any of my LC1's......

.....All my units read spot on in comparison to a dyno dynamics wideband after they've had the free-air calibration.

Quoted for truth.
Install LC-1 correctly, and you wont have a problem.

[thechuckster]

agreed x2 "good power source and good grounding" is essential for the LC1 to behave reliably.

Mine suffered from resets (during cold cranking) as the engine-chassis earth was piss-poor and the starter was trying to earth thru the sensor as well as the poorly-attached ground strap. Given that the controller was tryingto shunt a lot of current thru to it's own earth, i'd say that they made the unit fairly robust.

Also, if the sensor is mounted too close to the turbo, use a heat-sheild as specified in the install manual.

[JZA70 R]

Define resets?

I wouldnt be surprised if all units powered off during cranking, i know mine does. Or do you mean it actually factory defaults and starts running through its calibration process again? That would suck.

After all this talk about widebands i had the compulsive urge to go try my new wideband with my datalogit (power fc) ...the datalogit uses the analogue outputs from the wideband which are prone to misread if wired incorrectly.

I was pleasantly surprised to find my datalogit reading exact AFR/s as the digital output of the unit itself. It just means that extra time spent doing a proper install at the correct points paid off.

Its great to read all this input from people.

I like the idea of being able to read multiple outputs on the Zeitronix LCD screen, and the compactness of the round gauge (its flat and clearly lit). On the TechEdge kit I llike the multiple inputs/outputs. However, I still can't get 'over' the geekiness of the website and all the technical data. Several units (INNOVATE, Zeitronix) look professional and well constructed 'consumer' oriented products; the TechEdge gear looks like JAYCAR kits (albeit, well built and powerful).

HHmmmm. I'm still not convinced or should I say, swayed one way or another, about the various merits and otherwise of these kits. Given that the majority of them are based on the BOSCH sensor it comes down to the quality of the main unit, how easy it is to install (and keep out of view), and the quality of the software. I plan to use a laptop as I have an older COMPAQ laptop running Windows2K available to do all the main work but I still want some form of display as I want the unit permanently in the car (sensor, unit, display).

Once again, thanks to everyone for the input. Keep the comments etc coming!

cheers,

Peter

Or maybe I'll just wait for this ...



The LM-2 combines an air/fuel ratio meter, a full-function 32-channel datalogger, and powerful software to deliver a complete tuning workshop for less than the cost of one dyno day. Whether you have a piggy-back fuel controller, race carb, aftermarket ECU, ODB-II tuning software, or a flash/chip programmer, an LM-2 is the tool you need to dial in maximum HP. The meter’s digital signal processing technology provides data on exactly how rich or lean an engine is running at any load. The LM-2’s self-calibrating circuitry also compensates for changes in temperature, altitude, and sensor condition.

Patented “Direct Digital” Wideband Technology
Wideband O2 Compatible with ALL fuel types
Single or Dual Channel Version Available
OBD-II Scan tool- read/clear DTCs and log up to 16 channels of CAN OBD-II Data
Log directly to SD card (included)
Playback log data on screen and/or with powerful LogWorks software (included)
Large high-contrast graphics LCD
Built-in RPM converter (direct frequency or with optional inductive clamp)
4 fully-differential analog inputs
2 configurable linear analog outputs
Positive lock connectors for all connections
Innovate MTS serial IN and OUT
USB connection to your PC
The LM-2 also features two fully programmable linear analog outputs to connect to analog gauges, dyno computers, ECUs, piggyback controllers, and other devices with analog inputs. Analog output 1 comes setup from the factory ready for narrowband simulation; analog output 2 is configured as 0 volt = 7.35 AFR and 5 volts = 22.39 AFR. With the provided LM Programmer software these analog outputs may also be configured by the user.

$479 US.

Thats the unit I was looking at also. Looks impressive.

[thechuckster]

I wouldnt be surprised if all units powered off during cranking, i know mine does. Or do you mean it actually factory defaults and starts running through its calibration process again? That would suck.

would reset and loose calibration or corrupt the current calibration.

very annoying as it would happen when I wanted to go out and do some datalogging.

[thechuckster]

Peter: ODB-II would be of little benefit unless you have a modern Toyota (e.g. 1ZZ Corolla). Personally, i prefer getting logging data directly from the ECU - it sees all the sensor inputs anyway and a logging tool would only complicate any wiring.

However, a handy tool for calibrating the LC1 would be really handy as Innovate only have PC versions of their software and I'm mac based.

[infotechplus]

It's here. Ordered Sunday, arrived yesterday but I wasn't home. So had to wait until today.



I was still undecided between the TechEdge and the Zeitronix units when I went back to the Innovate Motorsport site late Sunday night to just check over some specs when the LM-2 came online for purchase virtually whilst I was browsing the pages! I thought it was too good to be true but I filled out the online order form and I received a confirmation from Innovate. So its taken 4 working days from the US!

Professional packaging but nothing fancy.



Comes with its own carry case!



What you get in the package ...

• Main LM-2 Unit
• CD with instructions and manuals
• One SD Card - 1GB
• A weld in bung and plug
• BOSCH Wideband sensor
• Sensor cable
• USB cable
• Power cable
• OBD-II cable
• Analog cable

Its Serial No. 18

Wow wicked, i have an LM-1 with full auxbox kit, and its effing sick! but the lm1 is a big unit and doesnt display much on the screeen, where as thats awesome looking!

Wait till u use the datalogging software, with the LM1 and auxbox in full swing, the data log replays are mind blowing. So good.

I want one.

[infotechplus]

Here's some more details.

The LM-2 is labelled with all the ports. The CD only contains V3 of the LogWorks software and all the manuals, even for peripherals and plug ins.

SD card inserts at the top of the LM-2:



The USB computer interface also connects at the top:



In / Out / Clamp. Not sure what these just yet.



The main interface is at the bottom of the LM-2. There are ports for two sensors, the OBD-II interface, power and analog I/O. I got the single sensor version so that explains the 2nd port being blacked out - the interface is there but its not connected internally.



The main unit fits neatly in the hand but it has a screw in fitting on the back, perhaps for a bracket to attach it to your dash.

Cheers,

Peter

[ONETEN]

Fuckin sick! now i almost have a reason to have lm1 & lm2.

Is this unit compatiable with auxbox? Auxbox has an incredible range of datalogging.

How much did the kit set u back and whered it come from?

Cheers.
