Will LM_1 show the graphic on PC of A/F raio vs the rpm? If yes. then why need LM-2? Need some answer please. THanks

 

you can but you have to buy an rpm converter, i think they are called. Otherwise it will only graph your air fuel vs time.

 

what does rpm converter do?

 

you can hook up a wideband to your ecu with Uberdata or other datalogging programs to display AFR vs RPM.

 

will the lm-1 basic kit have rpm vs a/f ratio

 

not unless you hook it up to run through your computer, which you then data log via a laptop computer. The converter lets you run a rpm signal to the lm1. If you search for innovative, or go to summitracings website, and search by company name. You can learn more about there add ons.

 

the base LM1 will only log air fuel ratio. the rpm converter will allow you to log RPM + 4 other '0-5v' signals, such as map, TPS, etc.
