I'm using mega squirt II with ITBs and an EDIS ignition. Well, I'll be using the EDIS when I get my pulley machined to fit the trigger wheel. I had an EDIS8 running off a trigger wheel in the dizzy but that wasn't reliable. Something funkey happened at around 5krpm. Seriously easy to tune the engine map with Tuner Studio (full version) and a wide band. Plug in, drive, autotune. Not expensive either. I haven't made much use of the logger license I paid for.
