The MS3PRO has been great so far. I've had a couple of bugs and am still working thru the tune but it's getting closer. I burned probably 8 gallons of E85 just sitting in the driveway trying to get it to idle. I have my VE table, AFR, Timing table basically where I want it and have taken the car out for some lite-load cruising using the autotune feature of TunerStudio. It works great and within about 5 miles of driving the car is idling great, comes off idle and accelerates great, cruises close to my target AFRs. Hot and cold starts are immediate. This particular model has all kinds of bells and whistles I still need to enable and test before going "full tilt boogie". I wired up meth injection control yesterday. I'm using it as a simple on/off and not staged or ramped but even so it has granular tunability for when to enable it;
