Single channel O2

Dan Fletcher · 07-11-2011, 04:57 PM

I'm looking for recommendations on a single channel O2 set up. My stocker has me frustrated, and I really think I'm out in left field fuel wise. My headers have a bung in each collector, so I'm equipped to install. Thoughts and recs would be appreciated. Thanks.

Dan, the best one I know of is a Dynojet. It has logging capability, and will log two extra channels besides air/fuel Vs RPM. I logged TPS when I was foot braking with the factory computer, so I knew when to start watching the air/fuel. You can also log fuel pressure, etc. It's not expensive, but is very reliable. You can download the logs to a lap top after the run.

I used an Innovate LM-1 to tune my LT-1 Firebird. Didn't know squat about EFI when I built this car and the LM-1 was a big help....and easy to operate. Record a run and download to a laptop and look at the log......Very nice software to manipulate the run logs.

Greg Kelley could easily get you fixed up with a recorder

.....http://www.motorsportsinnovations.com/

Handheld box/ set it on the passenger seat, push the button to record after doing a burnout and push it again at the end of the run. Disconnect the quick plug in cables and plug into laptop in trailer after the run...

A local ET racer demo'ed it for me and I loved it......

P.S. Dan.... we once had a short conversation at E-Town....You still had the EFI LT-1 Firebird and said you were going to dump it in favor of a '69 Camaro.....Was a good move! I sold mine as well.....and I'm glad I did....

Dan, I had horrible luck with the innovate stuff. We now have a race pack on Dad's car and I have the accel unit on the camaro that ties into the DFI. Both work very well, however the Racepak is only useful if you already have a data logger. The accel has a stand alone gauge and will log RPM/Driveshaft RPM and AFR

These units will work whether the car is "carburetor or injected"?? Dont' laugh!

Daytona Sensor has a really nice setup.

If you just want a digital readout you can easily see, the NGK Powerdex comes with a box that has the digital display that is easily read while driving, the sensor, the harness, and an output that will work with most data loggers.

No laughing here, I asked the same question once. An AFR meter does not care what is metering the fuel. It measures an air to fuel ratio in the spent exhaust gases. Shoot for somewhere between 12.5 and 13.0. I use an AEM wideband gauge and tuning is now very easy.

I've got the FAST unit with one sensor. I'm going to add the second one.
It records and plays back on it's own screen.

Floyd, your using the XFI system? I bought the second FAST O2 for mine after fighting an injector problem through most of 2010, on the opposite side from the one O2 sensor. The second one does not read the same as the one that comes with the XFI system. Not even the same brand sensor. Very dissapointed. My two only agree around 12-1. If you have a carb, not the XFI, their stand alone wide band records air/ fuel versus time, not RPM. Air/fuel versus RPM is much more useful for tuning. I have seen way too many problems with the innovate deal. I personally wouldn't use it.

Racepak gets my vote too. I just have a single O2, but I have bungs in both collectors so I can move the sensor if I want. Call Greg Kelley at Innovate Motorsports at 609-265-2110. He has very good prices and most of all has great customer service. Very helpful if you need someone to walk you through any of the installation.
