    Please help with solstice LE5 tune

    I own a 2.4L LE5 solstice, I have just installed a turbo kit from autowerks with a reflashed ECM but Im having limp mode and codes related to the map sensor, I bought hp tunners to send my datalog to autowerks to see where the problem is.

    My current set up is:
    PTE 5557 turbo charger
    60 lbs injectors
    2bar Map sensor
    Meth/water

    I wish I could open Hp tunners and solve the problem but I have no clue how to do it, please take a look if you can to my datalog, the ECM was supposed to be tuned for the set up, at the moment Im am driving my car with the stock 1 bar map sensor without boosting it.

    I hope someone could figure out what is going on

    Have you tried contacting them about it first?

    Yes they told me to send the datalog to them to see what was happening, its been one week since I sent it and still waiting for an answer. I dont know what to do, I live in Mexico and there is no tunner specialist in my city

    It seems that there is a problem with the barometric pressure, my mecanic says the barometric pressure is 50kpas instead of 100kps, he think that the ECM is still set to the stock 1bar Map sensor, the one they supplied is 2 bar.

    Since I had car trouble yesterday, I have my mom's Solstice 2.4l

    I pulled the stock file for you, def looks like the MAP scaling was adjusted on yours.

    It is correct, the ECM is still set to a 1 bar Map sensor and your new 2 bar sensor is working fine, they have the same working scale (0 to 5 Volts) to report twice the pressure so 100Kpa in the 1bar now means half the voltage of the new one so the ECU reports 50Kpa.

    Your calibration still need some work besides rescaling the map: There's no 2 bar patch for this car (that makes the ECU see the 2 bar reading right) so you have to make the MAF the main source for air measure and therefore recalibrate the MAF accordingly . Your EQ Ratio vs. RPM table and the Enrichment rate are stock which is very dangerous, don't try to boost having those values. Check the stock file of your 2006 car I'm attaching, use it as a file to compare so you can see the differences.

    Where in Mexico do you live? I have some friends there with HPTuners that can help you.
