Racelogic TC is no longer available. I picked up a second one shortly after they decided to no longer offer it. Sometimes they are offered up on EBay. A good tip is to check out EBay (UK). They can be spotted there more often. Just make sure it's for a V8 car. If the seller is unsure then the serial number can be emailed to Racelogic. They will gladly verify for you. They did for me on my second purchase.
