The 94/95 Mustang GT ECM is working great for me. I am using the Tweecer RT software to do my tune (primarily because I can do realtime datalogging) and everything has worked great so far. I am using the LC-1 wideband O2 to monitor my AFR and am actually logging through the Tweecer software by way of the EGR leads. The car has been running very stable and the AFR is right where it should be.
I think there is better software out there than Tweecer (SCT, AEM) but they are either more expensive than what I want to afford or they don't offer the datalogging functions that I want.
Bottom line is that the 91-93 MN12's just don't have a ton of support for their ECM's. That's the only reason I chose to go down a different path. I trust Lonnie but I wanted to learn this myself and the Tweecer offered me a more affordable route to doing that.
