    Innovate LM-2 rpm issues with Bosch ecu ski's

    I've used the Innovate LM-2 w/ inductive clamp to read rpm's on Siemens ecu ski's without any issues.... however it doesn't register a thing on ski's with Bosch ecu's. I've installed the analog cable, and soldered it directly to the #3 cylinder coil negative terminal. It does now register something on the LM-2..... but the reading dances all over the place, regardless or actual rpm. I've tried every possible configuration setting within the LM-2..... rising edge, falling edge, rpm options, pulses per revolution....... same out come. Rpm just dances all over the place..... even with the analog cable blue wire grounded. The LM-2 is running the latest firmware also. I'd greatly appreciate any input on this..... as I need to get some data logs done that include an accurate rpm signal.

    I had a similar problem with the siemens until I moved the analog wire to the coil wire near the ECU I think the high voltage coil EMP was screwing with the reading. You could also use the - injector wire.

    Might be time to sell it, and get the LCD-200 display for the CMD, so u can log a few goodies.

    Or get the vtech logger that have a built in afr controller - plug in innovate sensor direct to it without the lm2. And see rpm. Boost, temps , throttle and so on

    This is on a different ski. I have the LCD-200 on the RXP. It does nice logs, but otherwise worthless.

    The LM-2 works awesome for what I need at the moment..... I've just got to get this rpm signal issue figured out.

    I haven't had time to mess with it yet. I'm hoping I can get a good signal from the CPS.

    As mentioned, you might try the negative (trigger) side of an injector as well. This works as RPM input for our Wideband2 in stand-alone applications.
