    I used the guide from "The Tuning School" to set mine up. I did have to play around with one of the numbers or get it to match what the gauge said and what HPT said.

    No problem. One of the guys on Corvette Forum actually PM'd me about it since he knew I run the same wideband. 07MontRdcp is his username.

    Guys - thanks for the input here, where I am struggling is the BOOST side of the AEM Failsafe gauge. Has anyone got it to read / display properly. I got A/F spot on from this advice and would think Boost would be cake but struggling...... Interestingly raw voltage displays properly but can't get Vacum / Boost to represent

    Any help is appreciated.

    I had trouble with it too . Look at the preset aem pid , and create a Custom one so you can adjust the values .
    I set the main voltage to .5 just like the preloaded pid , then the Column that has the factory 10 offset voltage .
    I change it to 9.8 like someone in the c6 forum suggested and it was perfect .
    Just mess with the 10 valve by .02 + or -

    The gauge fluctuates so it's tough to watch . I had the best luck using stft histogram and just watching / logging idle to start .
