has the AutoProm which does emulation for realtime tuning and also has datalogging capability using various software such as datamaster. If you use the Tumerpro RT software you can datalog and emulate at the same time. I use this on my 93 and works great. Once you get your tune dialed in, you can then just burn a chip with the built in burner and run that instead of leaving the Autoprom hooked up.
