MPGuino Fuel Consumption Computer?

Has anyone here built/installed an MPGuino for their Windstar?

It's a DIY fuel consumption computer that interfaces to the vehicles VSS & Injector signals. My 2000 Windstar shows fuel economy but not instant realtime MPG's like this will allow. I have almost finished building mine and hope be installing it this week in another one of my cars. (Waiting on a few more parts to arrive) Some of you might be familiar with it, it is based on an open source general purpose microcontroller circuit called Ardunio and open source software to make it do it's job.

I plan on using a program called Advanced Serial Data Logger to log trip data from the MPGuino's serial port into a laptop. This software will recieve, sort, and log the data to a spreadsheet for me. I have experimented with this software on another project in the past and had pretty good success.

What I hope to end up with is data that can help me track performance, help me understand my driving habits and how they affect fuel consumption, and make modifications to my vehicle and be able to measure their affects on fuel consumption.

Here are some links to what I am talking about...

If anyone else has installed an MPGuino into their Windstar then I would appreciate to hear your calibration settings so help me get a jumpstart on calibrating mine. My reasoning for going with this vs. the scangauge is that I was able to build the MPGuino for under $35, I plan on putting one in each of my vehicles.

Will keep you all posted on progress if interested.

Yes, I'd be interested in hearing more about the MPGuino Fuel Consumption Computer. I'm sure others would too. I looked at your links some, are there others? Do you buy this as a complete kit or does part or it come assembled? Just not familiar with some of the terms...

Thanks for your continued information!
