Just got a couple of home-made gizmo's working in my Camaro:

1. Handheld computer scanner/logger. This thing plugs into the ALDL and scans the computer. It has a 4 x 20 display. It will also log 10 sets of data, 20 seconds each. You can then plug it into a serial cable and download all of the data to your PC and plot it in MS Excel. An added bonus for me was an additional jack to plug in the 3 bar MAP signal wire so it will record boost, and another additional jack to plug in the WBO2 sensor so it will record Air/Fuel ratio. Totally home designed and built - circuit board, project box, and all.

2. WBO2 data processor. I bought an Innovate LC1 and a Dynojet gauge (matches all the AutoMeter Sport Comp stuff, and has a NEEDLE). However, the Dynojet gauge uses a 10 volt input versus max 5 volt output of the LC1. According to Dynojet, they did this on purpose so you'd have to buy their expensive controller. My buddy designed and built a box that doubles the voltage from the LC1 to work with the Dynojet. We also included an input from the TPS sensor such that when the TPS is over 60% and the WideBand is leaner than 12.5, then a bright LED warning light will turn on. Pretty nifty, eh?

Anyway, these 2 can be purchased by anyone if you're interested.

Here's a TTT for you Mike. These are some neat little gadgets!

Are you confident the altered voltage output has not altered the accuracy of the LC1?

 

Yes. Dynojet told me the gauge uses a 0 - 10 volt input and it would not work with any other WB on the market. We tested my gauge by applying different voltages and found it to be extremely accurate and linear. The output of the LC1 can be programmed for whatever range you wanted. All I had to do was program the LC1 to output 0 volts at 10/1 and 5 volts at 18/1. After the circuit, this becomes 0 volts at 10/1 and 10 volts at 18/1, or exactly what it takes to make the gauge read properly.
