Here are some features: Measure, display, and record three axes of acceleration Lateral acceleration helps determine if the car is cornering at its maximum potential. Longitudinal acceleration can measure horsepower and stopping power. Z-axis acceleration can measure suspension motion or rear-wing down-force. 200 x 160 dot LCD display can show all three axes simultaneously and eight “soft” keys provide on-screen control. Entry level system has 128 kilobytes of data storage. This is approximately 72 minutes of recording time. Additional memory is available and PCMCIA non-volatile storage is forthcoming. Data is stored in user-definable files which can be replayed, deleted, or transfered to a PC using a standard RS-232 serial port (cable is included) for additional analysis. - ------- An initial price hasn't been set yet but should retail for under $1000 (and I'm hoping it will sell for around $600). Let me know if your interested and maybe I can get you a prototype that you can beta-test for me. The system should be going to the PCB manufacturer in a couple weeks. - -tim ------------------------------ End of DIY_EFI Digest V1 #191 ***************************** To subscribe to DIY_EFI-Digest, send the command: subscribe diy_efi-digest in the body of a message to "Majordomo@xxx.
