Default AFR gauge question

I am thinking of running an AFR gauge to remain in the car (maybe mounted in a pod) How can I set this up so that I can hook the wideband into my HPTuners when I want to use it for tuning?
I presently have an innovate system that I use with the HPT, but I want to have that for tuning the other cars.

The guage works on one serial port and the connection to HP Tuners is on the 2nd serial port. I have a gauge on an A-pillar, the LM-1 in the glove box, and HP Tuner interface connected for when I log.

Where did you get your wideband, and why is the LM-1 better than the LC-1? (I found a low price on a LC-1, but I remember that the tuner forum recommended the LM-1 for tuning.)

I have a special on all of Innovate widebands right now http://forums.corvetteforum.com/c5-s...-shipping.html
Which one you choose will depends on what features you want.

Interesting, you can run the LM-1 into HPT? How does the install work? I have tried a LC-1, but it is finicky and have not been able to get it to work again. So, I'm considering options.

I have the HPT pro, and my innovate LM1 just hooks up by installing the wires into the MPVI.

I want a AFR wideband kit, with a gauge, that I can mount in the car and leave it, but be accessible for plugging in my HPT if I need to do any tuning adjustments. I DON"T need a unit to do stand alone data logging. Not sure what all of the differences are between the LC-1 and LM-1 are, but, as stated above, I was told the LM-1 would work a little better with HPT. Not sure if that holds true with an in car unit.

The LC1 and LM1 are both good. The LM1 is designed to be portable and the LC1 is designed to be permanently installed. However, you can permanently install and LM1 as long as you can find a spot to fit it? An empty glove box works.

Here is what I did....

I bought an LM1 and the Innovate XD-16 gauge. I mounted the gauge in a pod on the a-pillar and ran the serial cable to the LM1 in the glove box. I power the LM1 via the ignition by wiring power to an unused 12v switched source in the passenger footwell fuse block. I grounded it at the cigarette lighter ground. This way the sensor starts to heat as I turn on the ignition.

On the second serial port I connect to the HP Tuners Pro interface for logging of the wideband data. With this configuration I can see the AFR in the gauge and log at the same time. I also didn't need to modify the ground offset in HP Tuners to get a proper reading.

The LC1 is very good but is more prone to issues because of the more complex install. The main issue people have with the LC1 is ground offset since they don't ground everything to the same spot or use a bad ground location. If installed properly I think it will work just as well and cost quite a bit less. Plus, there are LC1 + XD16 gauge bundles that are priced well.

As far as the sensor install...you have very little length to work with to connect the O2 sensor to the plug. I found going right up through the tunnel plate and up the shifter column just reaches to get the plug on the inside of the car.

Hope this helps.

Thanks falcon, That's what I was looking for.
It appeared from reading the articles, that the LC1 was made for a permanent install, AND I had also heard that LC1's had issues at times. I also wasn't sure if the HPTuners would "plug into" the LC1 for use in tuning. There's also SO MANY choices, and NONE of the vendors I have e-mailed have replied
If the LC1 could be made to work, it certainly would be more cost efficient, with some of them going for around $150 less than the LM1's
