One of my ECU's stopped working so I'm looking at upgrading my 1982 308 to the XDI. Any helpful suggestions? I'm using the camshaft sensor instead of the crankshaft. What timing settings work well with this system? Any shortcuts or savings to be had? I'll likely Ebay the rest of the ignition system once removed. The working ECU appears to be a newer one than the dud. It has neoprene gaskets instead of paper and a slightly different electronic configuration on the inside.
