I really paid too much. I ordered direct from PLX. Paid $150. Last fall.
I also bight there EGT module and was never able to get it work properly with the powerlogger. I'm not sure what the problem is but I'm not worrying about it til spring. Paid $50 I think?
Got mine a few months ago from PLX...I don't know the version though. So far I like it and apparently it can be used for other things too...such as a tach
I have a PLX system with Gage, Module, wide band Sensor, used it for about a week and changed computer system, new condition. Also have a new spare Module and wiring harness.
