Exclamation very useful gauge for us AFI folks

The guy who helped me install my Haltech gave me a heads-up about this, but I haven't been able to find one. I finally found it when I was perusing my Racer Parts Wholesale catalog.

Basically it's an air/fuel monitor that also monitors your injector duty cycle. VERY handy for those of us who want to make sure we aren't torturing our injectors. Also a very handy tuning tool. Since I no longer have the J&S dual monitor anymore I'm definitely getting one of these. Cost is $130.



You can find the product at the bottom of this page.

I called up Racer Parts Wholesale to find out how big the thing is just to make sure it will fit into my cockpit scheme somewhere. They gave me an estimate of the size since their warehouse is located off-site or something. According to them the unit itself is about 2.75"x1.5"x0.5". That seems pretty darn small to me, but that just makes it easier to fit somewhere in the car. Pretty cool though isn't it

Anyone know how it reads the injector cycle?

Probably uses some sort of waveform chip to read the duty cycle of the injectors and then an LED driver chip to light the LED's. *shrug* It's pretty damn cool though.

fyi, the apexi avc-r also can display fuel injector duty, along with speed, rpm, boost controller solenoid duty, boost, and thottle position. the bad part is that its all metric.

Yeah, but how much does the Apex computer cost? This is just a small and simple gauge. I can see injector duty cycle, air/fuel ratio, air/fuel correction factor on closed loop, BTDC, throttle position, RPM, coolant temp, intake air temp, voltage, engine load (boost), boost control solenoid duty, and a host of other things with a laptop hooked up to my Haltech.

But this thing is just a gauge, that's all.

Do you think that since it's for a high res o2 sensor, that means a wideband, and we could hook it up to the front o2 sensor?

My guess is they mean like a 3-wire sensor or something dumb like that. Basically meaning not one of the old really crappy O2 sensors. I mean they sell the "high resolution" O2 sensor right below the unit on their site for $70. There's no way you're going to find a wideband sensor for that kind of money. Most wideband sensors I know are upwards of $1000. Meaning the 5 volt sensors that require controllers.

And AFAIK there aren't any wideband oxygen sensors in any Subarus in the US. Both of them are just plain 1 volt lambda deals, but they will very likely work with this monitor.

I thought that the front o2 sensor was a wide band...or am I getting something confused with something else?

Some Honda models have their own version of a wideband sensor on their cars, that's the only ones I know of that come stock.

They have it for $100...

Wideband for under $1000...Good Luck finding that...

Oh and the Apexi AVC-R is crap....Just looks cool but uses parts that fail under boost higher than 1 bar...
