G-tech Pro Competition Accelerometer
This is a very handy "pocket-dyno". Currently, it does not read RPMs on a few late model cars, including the PT Cruiser. However, G-tech R&D has sent me data acquisition equipment to take snapshots of the PT's signature to remedy this shortfall, so an update is in the works! In the meantime, they sent me a spreadsheet that will extrapolate RPM data and construct torque curves. Awesome product, awesome company.
