wide band afr data coming soon...

[mbtoloczko]

I finally got my wide band O2 sensor and meter installed last night. The system is made by Innovate Motorsports. I've got bungs welded into both primary pipes, so I can log either bank of cylinders. The meter can log up to 45 minutes of data which I can download to a computer and plot. I also bought the optional analog input cable, so in addition to logging afr, I'll be logging engine rpm, TPS voltage, MAF voltage, knock sensor #1, and knock sensor #2. I haven't got the analog input cable installed yet though. Need to get some mil spec wire taps. I was hoping to get some afr data this morning, but I had to head into work. I'll have data this evening.

That's awesome Mychailo. Glad you have it up and running. I look forward to seeing your results this evening!

So why not just replace you stock o2 sensors with the wideband’s? I have been looking in to buying 2 of the Lc-1 form innovative but I have run in to information that says not to mount WB o2 so close the port. I like your setup. I very well may be running something like that soon my WB readings form my PLX M-300 are very helpful for tuning my turbo setup.

[mbtoloczko]

A WB O2 sensor produces a different voltage response than a narrowband O2 sensor. The LM-1 meter can take the WB O2 signal and output an NB O2 signal, but then I'd have to snip my SVX wiring harness and send the signal from the LM-1 into the ECU. So, I guess it just seems easier to keep the NB and WB duties separated.

Where do you have your OEM O2 sensors located?

[SVXtasy]

Right after the turbo

[mbtoloczko]

Less than 12" from the turbo?

Mychailo,
Very nice! I've been looking at Innovate's system, just haven't been able to justify the $350-450 price Are you using Bosch 5 wire O2 sensors? I'll PM you with some thoughts....

[mbtoloczko]

Not sure what sensor it is. Could be 5-wire. The plug has six pins. I rationalized away the cost long ago. :-)

[Phast SVX]

99% of the 02s out there use the 5 wire bosch that wears out rather fast if you just leave it in.

Checked the Innovate web site. Their system uses the
Bosch LSU4.2 5-wire, wide-band O2 sensor.

For my eclipse I'm buying a zeitronix wideband kit... Its a pretty quality kit. I'm getting it with the boost sensor and egt gauge also. All of it is loggable. check it out here: www.zeitronix.com

Also, you want to keep a wideband sensor at LEAST 18 inches away from the manifold.

Yes Less then 12" Why?

At first I was thinking that the exhaust gases might be too hot at less than 12" from the turbo, but after thinking about it, I doubt it. In the NA config, they are 24" from the exhaust port.

[SVXtasy]

Well my turbo is quite some distance form the exhaust port so I don’t think that heat will be a problem. But I would like to put two of the LC-1's in the stock locations. What is the problem heat? Or flow? I have heard both. If I keep my EGT's below 850c then the sensor should not have any problems right? Don’t the sensors work at everything below 850c EGT? Thanks

That one looks pretty nice too. I like the fact that it has a compact controller, a remote readout, and it shows afr and egt together.
