Anyone else running MSII and an EDIS? I've finally got my wiring loom done for the MSII and have the EDIS8 running 1 coil per plug but it's not quite right.

The EDIS PIP signal is only 0-0.8V and is not as clean as I would expect. The square wave has a fair bit of noise on it and every now and then the ignition farts and retards the timing to well after TDC. It's hard to catch though. Timing traces on the PIP and SAW look right on the oscilloscope. I had to mod the Hall input on the MSII as well to get the tach input to trigger (I've got a transistor driven by the PIP signal ground switching the Opto-Isolator http://www.megamanual.com/ms2/inputHEI.htm).

I'm thinking about filtering the PIP but thought I'd ask around to see if anyone else has had this issue first? I also tried swapping the EDIS unit and got the same result.

Thanks for any input.
