When I was converting over to fuel injection, it was recommended time and time again that you want to go with something that puts out "clean" power to the ECU; this is why I went with a CS-130 over the older SI alternators.

The SIs can put out "dirty" electricity that can possibly cause all kinds of random gremlins in the system. Even though it's from the 1980s, the CS series was designed with fuel injection and modern electrical needs in mind.

I also remember reading somewhere that the SI alternators may not pump out enough amps at idle to support the EFI system and fuel pump.

Food for thought.
