I'm not sure what the 2 is doing? Unless you're saying they fire every other revolution. I was under the impression that the saturn mpfi systems fire all injectors at the same time, and that they fire once per revolution. (i could see them fire once every other revolution if they were independently controlled). If yours are controlled independently of one another, then that makes perfect sense, and is a change from the earlier model years..

I'm seeing more than double your pulses at just a few hundred RPMs higher, and less than half of your uS..

Yes, mine is an MPFI.

You still have your resistor next to the guino, and not at the injector right? Maybe I do have connection issues..
