I bought a LM-1 wideband kit that Includes: LM1, Bosch 5-wire Wideband 02 Sensor, Analog Output Cable, 10ft. Sensor Cable, 10ft. Power Cable (Cig), 6ft. Serial Cable for PC Connection, Bung/Plug Kit, Software CD, and Quick Start Guide. My question is do I need anything else to be able to data log A/F ratio,RPM and boost(I have a 3 Bar MAP)? After reading the info that came with the meter it looks like it will only log A/F the way it is and I would need to buy additional parts to make it data log more that just A/F.

Do I have to get RPM converter?

 

Unfortunately yes you'll need the RPM converter to datalog and read any other 5v sensors. I'm still toying around with mine to get things figured out. It's not as easy as I thought it would be.

 

I'm still having trouble getting a good RPM signal from the RPM convertor. My signal is bouncing all over the place. I'm not sure if it's a ground issue or some kind of conflict with my MSD DIS-2 ignition system.

 

All I can say it keep trying. And make sure you are configuring it properly. Took me a long time to get the signal right.

 

Well it looks like I will need the RPM coverter Its just money
