Hi, Im new to the threads here but im a hp tuners customer and I would really appreciate any help you guys have. I turbocharged my cavalier about a year ago and need to switch to the 2 bar map sensor. It has the 2.2 ecotec, 5 speed transmission, 42 or 46lb injectors(cant remember), and a saab 9-3 turbocharger running 11 psi. The car runs pretty well and is daily driven at least 250 miles a week, but the problem is that I am only getting like 16 mpgs the way the tune is and could have a smoother more powerful range with the 2 bar map. I have the 12580698 map sensor from the cobalt ss and have tried cutting the resolution in half with hp tuners but cannot get it to run right. It seems as if whatever I try it is always WAY to rich, like 10.5afr at idle. Also I noticed that the fuel trims are maxing out in the negatives and staying there. Im hoping I can find someone who has faked a 2 bar map with hpt or knows how to. I will attach my current tune with the stock map for reference. Any advice would be helpful and thank you for your time in advance.
