You can do pseudo-realtime with the stock $EE 8051 PCM. Changes can be made on the fly to fueling, timing, etc, which can then be transferred into TunerPro to create a BIN which can then be flashed relatively quickly to the PCM. Of course this PCM doesn't handle direct control of coil-on-plug setups like the 0411 conversion from TORQHEAD and others would, but gonna put it out there anyway.
