    so then you are pretty much telling me that if I do not have a wideband to do auto Ve then this won't work..

    if so that is BS.

    you might might not be understanding what I am tryign to say.

    I just wanna take my car to the dyno put the sniffer on the tail pipe and change parameters.

    IE fuel and timing.

    Now the question is wich one do I use Backup or Main. and is there any other for fuel.


    I mean Auto Ve is like auto tune right. When I tune my EMs on my 4 banger i just tune it with dyno wideband and that is it.

    do you guys understand now ?

    thanks,

    Ed

    AutoVE won't work too well without a wideband because AutoVE aims to make actual AFR converge to commanded AFR...

    But AutoVE is not what you're doing.

    Will I just adjust the Backup VE table or the Main VE table in my 99 program.

    Also how do I tune with the NB02 sensor.

    don`t waste your time or fuel if you don`t have a WBO2

    If you only care about WOT, then when you get on the dyno, simply tune until actual AFR is suitable for WOT torque/power.

    Do you have a MAF...?

    If scantool shows MAP 100kPa and tunetool shows MAP 30kPa,
    then you need to do this (try step 1 first; if it still fails, do step 2):

    1. in scantool, Data F9 tab, rightclick on MAP, select Metric;

    2. in tunetool, Configure Display Units (~), for any table that uses MAP set data/row/col (as applicable) to Metric (rightclick, select data/col/row, select Metric).

    Once again, don't take this the wrong way...

    If you only are going to have the V1 for a short period of time and want to make the most out of one short dyno session where you will actually have access to a WB02 in the tail pipe (I hope you don't have your kitties still) then forget about AutoVE, VE tables, MAF tables and the whole mess. Just adjust the PE table and be done with it.

    I can understand not having enough time or resources to go really deep into this.

    or familiarize yourself with the tool/software on the streets,
    then do your dyno tune.
