  1. Re: MPTune and Ostrich - Boost cut-out around 11+ psi?

    Which table did you update that resolved your issue?
    You have a LM right? I don't think over-boost settings have changed.

    It's working for me, but it was slow. I think the system hosting the files just needed time to come up to operating temperature.

    Re: Cold Enrichment Tables CurveA, B, and C

    I've had both stock and +40s in my LM car and never felt like they needed to be adjusted. I don't have recorded the A/F at startup but usually in the mid 10s and works its way up to 12.5 and then...

    Re: Cold Enrichment Tables CurveA, B, and C

    I haven't had to change them. I just used what MPTune scaled them too or was was already in the T-LM/SMEC cals or BoostButton templates. Although I don't often operate my TM cars in the winter.

    Re: OTC 4000E Advance reading

    I'm writing this based on memory, so take this with a grain of salt, but the LM stores that "advance" value as some kind of calculation intermediate value, not the final result. It's always been in...

    Re: knock sensor dead ?

    Knock Volts should go up with RPM at least. So even in park, you should get *something* when revving to high rpm. Try swapping out the knock sensor and re-test.

    Instead of the Sensor Diagnostics, try creating a profile and layout with just a few gages like RPM and MAP and see if it records data while the engine is running.
