First off I'm not exactly working on a turbo Dodge. It's sort of an import actually. I have a 2007 Suzuki Kingquad 700 4x4 atv that I'm wanting to turbocharge. I have a computer that will work perfectly with a turbo, but I need to be able to monitor sensors and graph data to be able to dial it in correctly.
Here's what I need to be able to do:
1) Record data for at least half an hour, preferably longer and directly to a laptop.
2) Be able to take inputs from a minimum of 2 5V sensors, preferably 4.
3) Be able to graph a/f ratio against rpm, other sensors and time
4) Be able to configure parameters for the 5V sensors such as the TPS (0-100%) MAP (45-100kpa for the 1 bar) etc.
The four sensors that I want to graph as well as the a/f ratio are the MAP, ECT, IAT, and TPS.
To modify the fuel and timing maps in my ecu I need to know engine rpm and what it's reading on the MAP. There are a total of 288 cells that can be modified to add or remove fuel, or in the timing map to advance or retard timing. It's the perfect setup for a turbo because as the MAP senses increasing boost you can dial in added fuel and retard the timing!
Here's a screenshot of my volumetric efficiency (fuel) table so you have an idea of how this works and what I need.

I didn't even know that such dataloggers even existed until I stumbled across them doing some google searches an hour ago. All the ones I found were wicked expensive. I don't need gauges and displays, I only need to be able to do datalogging to dial it in.
If anybody has any idea as to what units would work that would be great! I'm looking forward to your response.
Thanks much,
Ben
