RE: Check Engine (TOO LEAN) after Tune???
Drbobvs: :-) I don't plan on changing anything at least until after I head down to MMR this morning. :-) But... if I decide to get a little something from Brenspeed... If you happen toknow, how long does an e-mailed tune take to get normally? Is it really a full week, as they mention on the website?

I don't know what to set the A/F to. I know you can adjust it, and if I were going to do that, I'd first contact the people who made my tune and ask them what it was SUPPOSED to be set at for the tune and then use the XCAL2 to set it. If that didn't work, I'd again ask them what to do. You should read up on A/F ratio. I don't know all the details, but I think I've read something like a ratio of 13 (???) is too high. Also, you could use the Livewire software with your laptopto see what the A/F is and adjust it to bea little lower and see how it goes.

Daniel60: That's good to know... I can send 'em the vehicle code and CAI type and they'll hook me up right off the bat?... Sounds good....
Thewarmachine: I think 13 sounds right... although, the MMR91 tune is already pre-set with all the individual settings... so that's why I'll head over to them first... I'm about 10 minutes from MMR anyway.
For all: If I have actually been running lean for whatever reason... have done any real damage to the car in the last 1000 miles? I drive hard... but not too crazy...

Hello Everyone... First post here, but I have to say, I've been reading for a while, and all you guys are awesome!
Now, my problem: I've got a high-flow MMR CAI and a 91MMR SCT2 tune on my '06 GT. I can clear the check engine light (warning says "TOO LEAN") and within 3 miles of driving, it's back again. Not REALLY too annoying, but it's slowly getting there. How can I get rid of it for good? Thanks in advance, guys.

171 and 174 are not the front O2s, they are the rears. NEVER mess with the spark and a/f settings.......only someone who actually knows how to tune should be doing this...you can make you car go boom......LEAN is not good, get it fixed ASAP....the 171 and 174 are normally from if you change to an o/r pipe, did you do this and not tell us?

There are three A/F ratios that can be changed with XCAL2 and Livewire (or Livelink...whatever it's called). You can change the idle A/F, the WOT A/F, and the mid-throttle A/F. I haven't done this myself, but I watched the flash demo that is on the cd that came with the tuner, and it showed those three options. Again, I'd probably never do this myself because I'd be afraid of messing up my car, but it is possible to do from what I've seen. Hope it works out for you. I don't like hearing about car problems of any kind, but especially computer car problems.
