I know better than anyone that our ECU is stupid. My engine blew after 4000 miles, and they tell me the car ran lean. I also hear that our car normally runs insanely rich. So I am thinking the car was all over the place that day, as far as it's air/fuel settings. My car stumbles and hesitates like crazy halfway through the powerband, also. For example, you are cruising in 2nd gear down an empty street, and then you accelerate (smoothly even) towards full throttle, that is when you notice it most. It feels like something is keeping the air and fuel from properly combusting, the car just doesn't want to go anywhere for a second. Not to mention, now that I have my Injen installed, I had a misfire or some crazy problem when I tried to get full throttle on the test drive after the install. It almost felt like fuel cut, but my boost is stock, how could that be? My next step is to get the Greddy Profec B Spec II (next week from my Greddy inside man). Then I should have the Greddy full exhaust in another few weeks. Once I have all of the air and boost control I need, I have to work on the timing and fuel settings. So please let me know if anyone is having any luck with the MPI/E-Manage, or other relatively inexpensive units. I can't see spending $1200 to fix the stupid ECU that factory can't figure out how to properly tune. I like the idea of the Haltech and other stand-alone units, I just can't spend that much money right now. Please let me know what people are working on. Thanks!
