wide band afr data coming soon...
 

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.

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?

Right after the turbo

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 :eek: Are you using Bosch 5 wire O2 sensors? I'll PM you with some thoughts....

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

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.

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.
