I have the HP tuners VCM editor suite and cable but I'd like to upgrade to the real time tuning upgrade and I would like to know if a new hardware interface is available where I can use a USB cable and a newer computer. I have an older hardware interaface where the cable is a 9 pin serial cable and I have to use an older computer. I've tried those Radio shack 9 pin serial to USB adapters but they don't work and I've tried everything.
Any info is appreciated.
Thanks
