Since greg is lazy, I'll answer for you.

The LM-1, meaning the handheld box logs against time unless you build a little signal to voltage converter. Greg did build one of these so he gets both.

If you want to use an LC-1 and don't have an added datalogger, then you will want to build something to provide RPM as well as the air fuel data. The LC-1 uses a DB9 pin seral connector and only the serial port send and recieve to log from the LC-1. You would have to build a datalink to log rpm though there are enough circuits on the web that you could copy if you have any electrical digital circuit experience.

With the LM1 you can log it versus as many sensors as you want up to whatever the maximum is. For tuning multiple cars, the LM-1 is the best way to go and probably worth the investment for as many cars as you play with if you felt like getting into tuning. You just need to tap as many sensors as you find necessary and feed them into the custom cable you will build for your LM1. THe RPM is the tricky one because it uses a frequency instead of a varying voltage. You have to make a frequency to voltage converter. THe other sensors you just can tap into in some cases.

****Sorry if it sounds complicated, it really isn't though. hope this helps****


Just FYI, this Basically is what Wayne of Hypillauto does. He uses an SCT Pro package (Dealer setup) and an LC-1 wired into it to tune and datalogg ford cars and sell tunes and chips.

I also saw a pair of dudes that did mobile tuning service go through texas. THey just called up performance shops as they drove around and set up appointments for the shops' customers that the shop didn't know how to tune. After they pretty much milked the local area of for people needing tunes, they drove off to another area.
Kind of a cool way to make money, Drive around in a Fast Mod'd car and earn your living working on them too. Actually they charged a lot of money too, like $50 an hour or so IIRC.
Armed with just an LM-1 I can tune any car that has an Apex-I or add on type of fuel computer. If the owner possesses tuning software it becomes easier. Something like the emanage allows a significant amount of tuning and those are quite popular in the import world.
With the SCT pro package (if I convert to dealer software) I can handle quite a few Fords too.
