I do highly recommend the DashDAQ but if you're on a strict budget, you can pick up just the ZT-2 Wideband, LCD and a fuel pressure sender and save $400. That will get you RPM, TPS, MAP, FRP and AFR but no OBD and you'll have to use a computer to datalog. Talk to Rob at Needswings. He is sually running specials and even if he's not, he'll take good care of you regardless of what you pick up.
