2010 Mustang V6 CAI Running Lean Code

[DiabloMatt]

here you go. sorry about the delay.

[kelbypep]

Thank you so much appreciate the help!

[DiabloMatt]

no problem let me know how it goes

[kelbypep]

Been running the tune for a couple of days now... so far so good it usually took a while for the light to come on. I have noticed a difference in how it runs. but it still has a minor hiccup every now and again when at idle so it may come up again. I will be replacing spark plugs and putting a performance distributor coil on it so maybe that will fix the idle. if possible could you give me a run down of what you changed.
Thanks again for all your help will always buy Diablosport for my Fords

usually it take fuel trim of 10% + to get the light to come on. so i added 10% fuel across the board under the assumption that cai was a bit larger.

Well the light came back up again for running lean on both banks.... will adding more fuel hurt my hp or help

if the car needed the fuel then me adding 10% should have made it feel better. did you notice a difference?

It was a little bit more snappy, but on start up it tries to find idle after I clear the check engine light really rough idle until it gets to 1k rpm then it calms down but when it calms down it sounds like a miss but it sounds like its cammed which its not. It is throwing up the lean codes on both banks.

The check engine keeps coming back on and when I clear it the car starts up and runs rough for a second then it re adjusts then the light comes on giving me the lean codes. I would like to know if I could get the tune that I had sent to me adjusted for more fuel.
Thanks,

[mikel]

[kelbypep]

[kelbypep]

[kelbypep]

Is there any way I can see a live feed of my fuel trim with my trinity I could also have a vacuum leak

i'll send you one with more fuel but i REALLY think you have some underlying issue. i dont feel it should be off that much.. try this next tune and see what it does.

[kelbypep]

well a vacuum leak could be an issue can I monitor my fuel trim?
