picked up a gas analyzer today

[katman]

I decided to go with the inductive. Much easier to do multiple bikes quickly and I don't have to remove the tank.

... those gauges will pack it in with a heavy fog. Not for outside.

I have used automotive gauges on the bike before without any issues. We don't get heavy fog here but I have ridden in the rain without any problem.

I was being funny. Innovate dude told me not to get them wet. There are on orings or seals in them. we get 9 months of rain here.

AEM makes a rubber bootie for 52mm gauges which is pretty cool.

this might give others an idea on how to construct an inexpensive sensor holder.

It might even be possible to get a small OD pipe down selected tubes to compare different cyclinders.

with this copper tubing construction it is probably possible in most circumstasces to push the sampler tube down different cyclinder down tubes.

Innovate has the most sophisticated O2 SENSOR i/f

The chart on the following page summarizes our findings across four categories. Of particular note was the
issue of re-calibration. All of the units certainly rely on the factory calibration of the sensor from Bosch.
The manufacturers may even perform some sort of a calibration of the sensor to their units during their
assembly process. However, as far as we could tell, only two units appeared to be capable of re-calibration
to compensate for sensor wear. The Innovate unit is self calibrating, while the NGK requires the user to
turn a knob until the display reads "CAL." Both measure the air-fuel ratio of free air to calibrate the
sensor.
This raised the obvious question: If a unit is not capable of calibration, how does the user know when the

sensor is going bad? We know from the Bosch data that the sensors themselves change as they age.

Innovate

The Innovate unit was accurate, exhibited the fastest response time, and included very good analysis software.
Innovate claims to be the only truly digital unit, and the high accuracy and low latency seem to support their

claims. Setup and wiring was complex and somewhat confusing.

Yeh, did a ton of reseach the last week. For older bikes they are the only way to go.
I wanted to get one that interfaced with my iPhone but none of them could deliver RPM and my EFI ECU only handles fuel.

I talked to tech support about using my Blackberry Storm to record data but there is no need as the LM-2 records all the MTC data (see the figure I drew).

You can still stick a laptop and SD card reader (I got a cheap USB version and newer laptops they are built in ) into a backpack or just wait till you get home to see the data on the PC.

forgot to ask, you can use any SD card right? The O2 sensor is Bosch so that is standard.

Here is a short aricle using the LM-1 and LMA-3 to instrument a HD. The LM-1 is an earlier version of the LM-2. The LM-2 has the OBD-2 reader which comes on post 1996 cars.

Sensor placement is very important, and is more accurate mid pipe than from the tip. Learned alot about wide band O2s when I turbo charged my car. If the sensor is too close to the head or turbo, you can burn it up, and get false readings. Rule of thumb is 2-3 feet from the exhaust port. In cars after cat is pointless, the cat converter is supposed to clean the system. My WB O2 is not hooked up to the tach, but is hooked up to a Mega Squirt stand alone ECU.

The slip in adaptor between collector and muffler is perfect placement I my self didn't like the Innovative and went with an Autometer. Way over priced but works better IMHO.

What do you think about that DYI sensor mount with the long pipe? Is there too much cooling because it violates the 2-3 foot rule?

very interesting site. I'm looking for at data monitoring with the possibibilities for doing diagnostics rather than ECU development. Anyway looks like you can go crazy........

Well, that was short lived.

SEnt the whole shootin match back. The RPM pick up was useless and from what I have read the LM-2 can't produce a reliable RPM signal.

The unit itself kept crashing and restarting itself. Sometimes several times a minute. Talked to Philipe at tech support and he was no help. I asked for a replacement unit and I was told that won't happen. I had to ship my one day old unit back for repair/analysis. I said that won't happen.

So, on to another system.

I sure hope that all this money/effort is being put forth to a track only bike... Otherwise, it's a colossal waste of time and funds.

Care to elaborate?

STREET BIKE. Don't think its a waste of time and money to properly tune bike for the street. Have a look around this forum at aaaaaaaaallll the dudes having problems with carbs. It is endless, an analyzer gives you quick answers and directions to go. Rich? lean? rich? lean? no its rich? no, its lean! IMHO it is a time saver.

Also, this is primarily for tuning my efi/turbo.

Well sorry to hear that Rob. My first try at starting the unit up did not go well either. Even though I had two new disks both with the purported latest software, after talking with tech support I had to reload the PC software to get either the PC to recognise either the LM-2 or LMA-3. That seems to be working now and I'm still piecing together parts.

It seems better now but I'm still assembling and trying to figure out a way to do the exhaust sniffer.

The O2 sensor worked for a while, then would not heat up. I'm hoping it was my power supply. I have two swap to the big mama but have not gotten there yet. I'm not sure that I would send it all back just yet. The LMA-3 has a more filtered input for the RPM. Also the app notes say to drop the voltage some using a pot if you don't do the inductive input.

Well I still have a few options to work on.
