I'd be interested in "ZT-2 Wideband AFR Meter and Datalogging System" for $265 and the USB Serial Cable for $25. The question is, do you ship outside the States and do you still accept PayPal although my address cannot be verified? I'm in Europe.

Question. Doesn't the Eclipse/Stratus ECU reconfigure itself around the AFR hookups? I'm curious.

Oh, and does the "USB" cable hook directly into the OBDII or is it used for the AFR meter?

This is more for if you have a power adder of some sort.

You need some form of fuel tuning device to adjust the fuel to make this worth it.

USB adapter is for hooking up the system to a laptop to log the data.
