MAFT tuning
Re: MAFT tuning i hate it when nobody replies to a straight forward question of mine.. so here it is for you
for wide open tuning our oxygen sensors are not calibrated to read 'perfectly' so the %error is greater than what you would want to bet money on, that and the light gauge is really hard to pinpoint an exact voltage.. with autotap i say you have a decent tuning ability, but the gauge is mostly to just see a good or 'bad' situation.
dont get me wrong you can definitely use it and make changes in the right direction.. but not 'optimal' like you said

Re: MAFT tuning what about the digital ones. i seen one on ebay that reads the voatage off the sensor. is it any better.

Re: MAFT tuning If you think you're running rich, easiest thing to do if you have ATAP is to monitor your O2's anyway, but knock most importantly. Do a few fourth gear runs with autotap, and review to see if there was less than 3 degrees of knock. If you see there was no knock, lean it out another 2%. When you start getting knock, you should stop adjusting. I did this with mine, and on the wideband, only had to change it 2 more percent lean. Hope this helps.

Re: MAFT tuning A digital read out will give the same numbers as atap, but it is difficult to watch the o2 voltage during wide open runs at 100+ mph. Easier just to log wide open runs with atap, and that way you can also monitor coolant temp, air intake temp, timing advance and knock retard. I usualy shoot for an o2 voltage of between .905 to .915 volts.

Re: MAFT tuning You could always run a Scanmaster like i do.. its on my dash and in my view while im at WOT. you cant see real time 02 #'s and Knock retard.
