ok, so the blue box isn't a reliable option. So, I need a chipped ecu huh? So, I need to purchase an obd1 ecu that I can program/have programmed with some editing software such as crome or uberdata? What EXACTLY do I need to purchase for this setup? I hear I need a wiring harness for the obd1. What harness is this exactly? Is it the harness that plugs into the individual sensors for the engine? Is it a big ordeal removing it from the car? With the uberdata or crome programs, can I use other peoples programs and load them onto an obd1 ecu that I get? I know these questions are probably basic, but I'm trying to learn about this aspect of engine management, so bear with me here.
