do you need the rpm converter to datalog. or can the basic LM-1 for $349 Also if u use the Logworks software how do u like it.

thanks

 

You can datalog with just the lm1 but it will only plot afr along a timeline, you will have to make an edjuacted guess what rpm you were at and remember what map pressure you were at. I did it this way to tune full boost pulls a few times and its not too bad except if you run into quick spike and you have to figure out exactly where they are. Then you have to record lots of quick pulls over just few hundred rpms so you can tell where you are.

 

ive only used my lm-1 on the street with a friend watching the a/f while i drive. wouldnt you need the inductive rpm pickup to do a complete datalog (a/f over rpm)? ive heard some people a while back had problems with the rpm pickup spiking alot...
