Well the LM1 I have already give a AF reading but yes this will give a scrolling readout
In Runtime Ticker-tape mode, the parameters displayed include current engine operation state (cranking, running, etc), enrichments, barometric pressure, engine MAP, coolant and intake air temperature, all computed enrichments, and injector pulsewidth. The automatic scroll mode can be frozen at any time in order to monitor any desired variable. In addition, any monitored parameter which is outside of normal operating conditions will "flash" on the display, alerting the driver of a possible adverse situation in real time.
The configurator mode will allow the user to adjust any of the configuration parameters. This is useful for field-tuning and variable tweaking. It is not designed to replace the PC Configurator for tuning, but allows for simple parameter modification as needed.
It comes in kit form but only takes an hour to put together, link by rs232 to the ecu.
