I love the fucking thing, it's a Zeitronix ZT-2, about $270 w/o a display, egt probe, or boost sensor, http://www.zeitronix.com/Products/zt2/zt2.htm. I run it without the display, EGT, or boost sensor (for now), I log on my laptop.

A wide band guage can cost just as much as this logger, and forget having to read the guage, make WOT runs, and try to guess what RPM you need adjustments at, all while trying to stay on the road. Price an EGT guage, boost guage, none of which you can log with and this thing is a bargin. You can graph RPM, EGT, boost/vaccum, TPS, user imput, ect. Just hook it up, go out and stomp on it, pull in to a parking lot, make your adjustments. Installing it was cake. I just tapped into the wires from my SAFC.

You'll need a laptop to log, and an o2 bung where you can put the wide band o2 sensor in (sensor's included), or you can use the simulated narrow band out put to feed your stock ecu and install the new sensor where your old one went (yes, it even has a narrow band output, and a 5v out put for an an axuliary boost sensor). The unit is very small and can be mounted well out of sight. It's an awsome piece. My computer connector is tucked away in the glove box.

I guess you could order an extra harness and swap it between your cars too. Just don't run the o2 sensor in the exhaust stream w/o power or you'll ruin it.
