    Default LMM tune makes no difference to power

    My LMM conversion is at the tuner. He is saying no matter what he changes no difference in power output whatsoever. The tune flashes fine with no errors.

    I am wracking my brain to think what could be the problem. He is an experienced tuner but favours HP over efilive, however i have requested efiive for the dsp5.

    I pulled the tune with 7.5 and deleted some codes that are irrelecant for a retrofit, reflashed many times with no issue, vehicle drive great. I then converted to dsp5, installed the switch, flashed that and sent it to the tuner along with a copy of the file (as he cant pull the dps5 himself).

    He is trying to tune it with 8 on my 7.5 file as his starting point, could this be a problem?

    I suggested he reflash the non dsp5 file with 7.5. Re read it with 8 and go form there, or should he be using 7.5?

    Assistance greatly appreciated as i am on the clock here

    Thanks

    Lots of missing information because it's second hand.
    Did you verify the switch operation via the voltage paid and switch position pid?

    Depending on what you turned off for the swap, it could possibly be in limp mode as the e35b can be a stubborn bich.

    Have you verified app d?

    What is the fuel rate mm3 achieving during a pull?

    You have to verify that switch. Then I can make suggestions as to changing something, flash it, and see if it cooperates.

    Did he set the switch voltages up correctly in the tune?
    Thanks,
