Its probably the first time since 2007 when I bought my Predator U7145 to tune My Mustang GT 2007 with K&N CAI....my experience was incredible!!!.....I repeated on my Mustang GT 2008 my Predator U7145 with software V. 8r07 done great with JLT CAI Serie 1.....
sadly that Cold Air Intake broken, and I ordered a new one....
Begun my headache after turn my car on.....RPM went up and down from 500 to 1000 while my car was neutral.......first I thought its was going to be until Computer made adjustments........drive the car ....25 miles....feeling the car some funny....so the office....and after 3 hours.....I got on my car....turned on....and it continuously does the same RPM down and up....
After 1 or 2 miles ...my engine yellow light on dash turned on....
I arrived home and performed a diagnostic with my predator U7145......and its shows codes P0171 (system to lean bank 1) & P0174 System to lean Bank 2)
So I begun to search ( wow!! after almost 8 years NOT PROBLEM with my predator and my mustang ), i found some people complaining about the same but Find a solution.....What did I do?
1.- Reset codes on Mustang by battery disconnection more than 5 minutes
2.- Downgrade my Mustang to stock tune ( it doesnt start after I did)
3.- Updated U-7145 from 8r07 to 9r07
4.- Upgrade my Mustang from Stock tune to CAI Induction on new software (9r07)
What did I get?
a) Mustang started, but with same RPM problem (up and down)
b) No light on dash ( but remember I reset codes....and I did not drive car just started)
c) After some gas push I got Brake on alarm 2-3 time when RPM hit 4000 rpm (WTF
)Any suggestion from Diablos Team? Probably on forum there is an answer....but I didnt find it....I apologize for it!
I will upload my tune....By the way.... I did find JLB CAI tune for 91.....but I use 95...please be aware about it...and extras: Only Borla Exhaust
Thanks for anyone who would like to help
George
