    Need A tuning Guru!!!

    Thank You for reading this,

    I have a 2002 Camaro Z28 that with the exception of a rough warm up and wanting to stall on deceleration to idle, runs pretty good. Iím getting a blinking SES light thatís driving me nuts. The real weird thing is that it only comes on while in gear at an idle, voltage maybe???. I did a scan and I'm getting a 1153 (Bank2 fuel control shifted lean and 0171 (Bank 1 system too lean) I checked for leaks after the MAF and found nothing. Injectors are good, plugs & wires are new. Then it occurred to me that I have no CATs, a big cam, ported heads, a 4" Mufflex exhaust and no rear 02 sensors. That does explain my car running lean beyond the parameters of my fuel trim. My question is, What, if anything, can I do in HP Tune to correct this problem and make my car safe to drive???

    Please & Thanx!!!

    Be sure it's not the front O2 sensors just being too
    damn sleepy, and you have all the other codes that
    usually tell about this turned off already?

    A blinking ses light means you have a misfire, HP tuners will help to make it run good.

    I would figure out first why your getting the misfire. Then work on tuning it out figure out why its dying at decel. I dont think the o2 sensor will be that important to worry about specially with your setup if you run race gas at some point you will toast the sensors on the car. On hp tune watch your fuel maps on decel I will look at the program tonight see if i can find somethings to help you out.

    You should consider taking it to a professional to smooth things out. For beginners, your own software is nice for little adjustments but it sounds like your car needs a good amount of finessing by someone who is familiar with the ins & outs of hptuners.

    your right about that. First before you take it to a tuner you need to work out the misfire issue if your having that problem. Last thing you wanna do is sit on a dyno and pay for time thats being wasted looking for an issue that could have been fixed at home. But keliente is right a good tuner will be able to have you in an out in 1.5 hours

    Artist: The Animals
    Song: Year of the Guru


    My leader told me to jump in the river
    The river was deep and the weather was winter
    After a sailer very kindly saved me
    My leader told me, you'd better take it easy
    I took it so easy my leader called me lazy

    Through the lack of red meat
    Everything was getting hazy
    Friends looked at me and said,
    Man, you gotta be crazy

    Oh, oh leader

    My leader said son you'd better get yourself together
    never mind the fools who know what we're getting into
    But a forty mile walk would do us both a world of good
    and he sat down and watched me take off down the road

    Well, I walked so far my feet began to bleed
    If this was good for me I just couldn't see it
    A motorist picked me up and said
    Look man, you must be crazy

    Oh, oh leader
    Oh, oh leader

    My leader came to see me in a hospital bed
    Well at least I really knew that my leader really cared
    After giving me a second-hand roach
    He said where's your donation man,
    It's all for a good cause.

    He left me all alone to work the riddle out
    But I just couldn't make it so I began to shout
    They stuck a hypodermic deep down into me
    Said, look out nurse I think we got a loony

    Oh, oh leader
    Okay baby follow me now
    Follow your leader
    All right

    Now here I sit in a state-run asylum
    Limitless, friendless but much more together
    I decided to do some good book readin'
    About the art of people leadin'

    Now I'm the leader and they're being led
    What's the matter if they're crazy till you hear what I've said
    Being the leader is really where its at
    But just how long can a good thing last

    Oh, oh leader
    Oh, oh leader

    Now listen to this baby
    This is the year of the guru
    Now the thing to do is to ask yourself
    What can a guru do for me?
    Then you say to yourself
    I gotta get a guru
