I will be putting in my first LSx engine soon and would like to be able to monitor the engine, especially during startup. As best I can tell the only options I have are HPtuners or EFI live, both which set me back several hundreds of dollars.

Does nobody make any laptop software that can read/clear codes, log data for later review and have a dashboard to monitor parameters in real time?

I found this http://www.obdcom.com/index.htm but for some reason I have that "somethings not right about this" feeling.
