Re: Play back tach
I use an Autometer Ultimate and am extremely happy with it.
It allows you to log the driveshaft speed and, if you buy the sensors, one pressure and O2.
I do not use the O2 feature as I have that on my MSD Grid, but I do log my oil pressure.
Unfortunately, it is a little more than your budget.
