Just starting on the lm-1 and I just need to know how to convert the volts to rpm...

 

Since its not stated do you have a lma-2 rpm converter kit or the lma-3 aux box.

Since rpm's are measured by ignition pulses these are supposed to do the calculation for you, or so i thought..

 

i have the lma-2 rpm converter. not sure if i did the setup on the RPMconverter correctly. at around 850 rpm on the tach, the log shows .22 volts. When i try to setup to show RPM instead of volts, the rpms are way off.

 

btw, i did a direct connection from the ecu for the rpm readings, i didnt have an induction clamp.

 

I pulled out the LMA-2 manual and read it for you

According to chaper 5.2
http://www.innovatemotorsports.com/s...MA2_Manual.pdf

The steps are:
-Connect and power up the LM-1 and RPM-Converter as described in Chapter 4.
- Make sure the Indicator LED is lighting up steadily at 2000 RPM.
- Press and hold the Setup button on the RPM
- Converter until the Indicator LED on the RPMConverter blinks rapidly.
- You have now 10 seconds to rev up your engine to 2000 RPM while the Indicator LED blinks rapidly.
- Hold the engine at 2000 RPM ( +- 200 RPM) while the Indicator LED blinks. When it starts to blink slowly it is taking measurements.
- After a total of 15 seconds the Indicator LED will light up steadily.
- Relax, you are done.

If you need chapter 4 here you go:

4. Using the RPM-Converter with pulsed RPM input (Tach) signals
- Unplug the inductive clamp from the RPM converter if connected.
- Connect the RPM signal to the RPM pulse input screw terminal.
- Plug the RPM-converter into the LM-1 unit.
- Start the engine.
- Switch on the LM-1 unit.
The indicator LED on the RPM-converter should light up steadily. The indicator light indicates
when a valid rpm signal is detected. If it does not light up, check your connections.
DO NOT CONNECT A PULSED RPM SIGNAL TO THE INDUCTIVE CLAMP INPUT. THIS
MIGHT DAMAGE THE RPM-CONVERTER OR LM-1. Again, this should just result in an
error code, not mechanical damage.
In most cases the ground connection of the RPM converter is required only if the other Aux
Inputs (2-5) are



EDIT:
Best of luck

 

ill try that rev to 2000 thing, and thanks for the help. if it doesnt work then ill be back.

 

You could try reading the manual yourself you know

 

me no english...
