cheap but good wideband

LC-1 by innovate. Best performing for the money. They show up on ebay for $170 without the gauge. I use my old narrowband light show gauge and log with the input to the ECU. The only one cheaper is the JAW, which I've had problems with.
 
If you want cheap & reliable I'd probably go with the Innovate DB gauge kits.

We offer the Innovate DB Gauge kits in red or blue for $193 shipped which is about $20 more than the kits without the gauge :)
 
I'm another advocate for the Innovate LC-1 kit with a DB gauge. I'm running it now in my car, got a new one for less than $200 shipped, the gauge looks nice, and the LC-1 unit has TWO programmable outputs and comes with software to program each one and log through a serial cable. Oh, and it's also supposedly more accurate than the AEM unit. There was a comparison study done a while back.
 
AEM cheapest most accurate. You want a good wideband you will be using it all the time. Its you main tuning tool.
 
AEMs are good too, and I used to use them myself. But the LC-1 innovate system is almost the exact same price as the AEM ones and are more accurate and are more adjustable/programmable for different situations. You can have program it for pump gas, race gas, diesel, methanol, ethanol, etc. You can also program either of the two outputs to be narrowband or wideband or anything in between.

It's fairly easy to install. It will come with an o2 sensor bung to get welded in the exhaust. You CAN also just use the rear o2 sensor bung, but it may not give you the most accurate reading. Then just run the wires into the car somehow. I ran them through the floor under my driver's seat in my 2g. Then there are three wires to connect to the DB gauge. A power wire, signal wire, and a ground wire. It also has another signal wire that you can wire into the ecu to log with DSMLink. OR you can use the software it comes with and connect it with the serial cable it comes with or use a USB-DB9 converter if your laptop doesnt have a serial port. If you can install a boost gauge, you can install this.
 
Thanks guys look like that the winner. How hard is the install

As long as you can spice and solder wire's, you can install it. You just need a +12v source, a +12v ignition source, and a ground to install the wideband. If you want to power a gauge, that's just a few more wires.
