Iam currently running a msd vtec switch set at 5K. I want to keep this setup. Iam running a crx si ecu right now. With the crx si distributor. Which ecu can I use to run the vtec off the ecu instead of the switch? The car is a 97 d16y7 block with a y8 head. I love the setup right now. Just want to get rid of the msd atavtor switch. I need some ideas. what ecus to use. Can I use the pr3 and have it chipped?
