computer guru's come on in
 
Ok, I decided to get my setup dialed in and when i put it on autotap, it was pig rich(910-.930 o2's). I have bein running throuh a catback , but this is when i took off my cutout. Now, how long does it take the Computer to realize the new found cutout is off? I have autotap and a translator and was wondering if i dial in the catback and then with the cutout off, can i just switch the settings, or will i have to let the computer relearn itself? I had the base set at 2 and the wot set at 3, my ltrims are constanly wack, at idle they would be at 0, then at cruise one would be at say -1.3 and the other at +1.3, any info would be greatly appreciated...

The computer learns pretty quick. I would say do some new runs and logs and dial in the MAFT to correct levels.

Just my 2 cents.

It is not uncommon for side to side LTRIMs to vary by 3%. Consistent larger variations (e.g. over 5%) would indicate a potential problem on one side.

BTW, LTRIMs often change as you drive and utilize fuel trim cells, a range of LTRIMs of +/- 5% is not really whack in my book. . I wouldn't worry much about your base and just tweak your WOT.
