I just got my 07 GT through AZ emissions - w/a PASS.....!
What a "PITA"..
I had a battery disconnect - which cleared the ECM ( I forgot about that) so it read nothing on the first time through - but no charge - so I saved the $28
I was smart way back when - like 5 Yrs ago......
For the Breenspeed 'tune' I bought - I had a separate tune set up w/the O2 sensors 'on' -
Saved the original H - pipe w/the 'cats' from FoMoCo
Spent a weekend switching it back over ( the bbk shorties 'stayed' on) - uploaded the O2 'on' tune - then drove it for a few days (resets the ECM) - had a mechanic buddy 'scan' it before I went in there and make sure all the modifiers were working... modifying....and Bam it PASSED.....
It was the first time going through any emissions place - and man was I worried - spent all this past weekend on my back by myself in the garage - but my ill conceived plan from 5 yrs ago 'worked'?....so the prius driving - sandel wearing, tree huggers can be happy for the next (3) three days or so- and then they can start 'crying' again............. cause I'm switching alllll back!!!!!!
