i guess that im not. what is the most user friendly wideband for a decent price that is user friendly cause i guess i will be buying one sooner than later.i almost wish that there was someone in my area that i could borrow one from.

I picked up a LC1 seemed to have a good rep, just be sure to Not leave it on unless the motor is running. :doh2: a thought just hit me, tie into the oil pressure switch (or install a 2nd one) use the feed to control a relay that powers up the LC1. A second switch would work best after thinking about it. :thumb_yello:

I using 1 no need in the cost of 2, actually Mathematically it may be easer for the program with only 1???? I'm just a tight wad!!! lol
