its my brother in laws...he said he used it in his turbo rx7 and supraand paid 900 bucks for it when it was new quite some time ago so im guessing it is a good tool for the right person. it has a few piggy back setups to it so im not sure what cars its compatible with other then the two he used it on. From the looks and reading it, it is a fuel management computer and says it helps stock-mild modded motor perform better. im not familiar with these and i know its old so im researching tgo see what it is worth, so please just make some fair cash offers. could probably be used on any car with a turbo set up with the correct piggy back. PM me if interested!
