I was talking to a dyno shop the other day and they told me about a device that is due for release this summer by dynojet. It is a wideband o2 setup with a digital gauge and sending unit etc. for tuning your car. Best thing about it was he said it was supposed to be in the $400 area.

Anyone heard of this?

I think vector is refering to an in-car module like an AutoMeter A/F gauge, not a wideband used on conjuction with a dyno.

yeah this is a unit you put in your car. The clear interest of mine is that at $400 for a complete kit, this is cheap (if it includes the o2 sensor).

Yah, there seems to be an insurgence of companies jumping on the wideband bandwagon now. AEM is due soon to release a wideband setup for around $500-$600 and is geared primarily at EMS users, although they will be releasing a display for the device as well. Still, the cheapest are the DIY kit or the Tech Edge setup, both of which unfortunately use a relatively hard to find sensor (L1H1). However, Tech Edge V2.0 will be utilizing the more readily available Bosch LSU4 sensor.

I can say that I'm happy with my Tech Edge V1.5 unit. However, I was able to get a sensor for it at the end of last year for $149, right before the prices jumped up above $300 and the availability dropped near to zero.

hey shark,
does the tech edge unit send a "regular" O2 sensor signal back to the ECU?

I was lookin around the site but it wasn't really clear.
also, what are you doing with the wideband signal? does it go to a gauge or are you using it in piggyback or something?

The v1.5 is capable of producing a simulated narrowband O2 signal for the stock ecu. However, I wouldn't rely on it. I prefer to let the stock sensor and ecu do their job as they were designed. I don't trust the simulated output to be reliable. People have been using it that way, though.

I have the Tech Edge display. I can also use my Palm to display and datalog the a/f output. I haven't used it for this yet though because I (and others) have been having trouble getting the Palm to datalog RPM along with the a/f. There is apparently a new chip for the unit which resolves this issue, but I haven't picked up the new chip yet. So for now I've been trying to tune by running around in the car and keeping my eye on the wideband display :laugh: Crude, but effective.

The Supra community has been using the FJO Wideband with lots of success. It offers the datalogging capability, PDA ability, in car display unit.

It's nothing new. I think it's funny how so many kids will go out and drop $50 for a useless Autometer A/F gauge for it's neat blinking lights that just go back and forth.
