Having bought two Innovate lc-1s and having one blow on start up, and having another lose the analog section after a couple of years, I have a replacement for the first one still sitting in the box.
I would buy the AEM or the Plx before I bought another lc-1. I have not checked the forums lately, but, there were many posting with the same problems as me. I did not see as many problems with their LM model.
the factory sensor is a narrow band sensor which means it is only truly accurate at 14.7 to 1. See the write up on my site. I built my first wideband about 12 years ago and I still use it on my carbureted cars at times.
Wide band sensors give an air fuel ratio that is generally accurate between 10-1 to 17-1 air to fuel. This is very handy for tuning seriously fast cars. After several years, I have realized however, that I can tune just as well using the factory sensor and going as lean as possible without incurring timing retard...when I see a hint of retard, I add a little fuel or cut the boost a pound for safety margin.
I know this is heresy, but, let's face it, guys have run into the Nines without a wideband so it is not much of an effort to run safely in the elevens. Some guys bench race theory all day, I prefer to run whatever works for me.
At the moment I am running open loop speed density chips in both cars...I am running open loop because the the wide band failed on both cars so I said to heck with it. One car has the digital side working, but, the analog side which drives fueling is dead. If they die at the wrong time, it can be quite damaging.
