Most modern sensors (not all) provide a 0-5 volt signal to the ECU/PCM. Like I said before, buy the OT1 the rpm reading will be accurate enough (I believe it samples 12 times a second). As for jacking up your car and doing a 4th gear pull you should really think about spending the money on some dyno time and we’ll give you a rpm/af printout and copy it to your jump drive if you like. For $149+shipping of the OT1 you could do a few different dyno sessions and actually get alot more info… ya I may go foe the OT-1. of course, when I want to tune the fuel for power I’ll be going to a dyno. plus the only way for me to tune the cam gears would be on a dyno. I just want data logging in the car to keep things stable. --- _[View the full topic](https://forums.speedlife.net/t/lc-1-xd-16-standalone-but-i-want-datalogging/202098)._
