I use the RPM brand. Really easy to use, good pricing and the sensors aren't as expensive as the Racepak brand. If you want what is considered top of the industry then go with Racepak, but I really like my RPM. Randy that owns and builds them is very accessible. Give them a look. Do you have any specific questions about them?

I log engine rpm, driveshaft rpm, voltage, O2, vacuum, fuel pressure, and converter slippage.
