Did you look to see if you have the Bosch sensor like in the picture I posted ? |

Think of the ECM as being "wide-open", in an "out-of-control" state, in the neutral zone, with all the tables frantically, trying to get in sync with each other, to deliver the desired "torque-curve", that the ECM was programmed for. The ECM will quickly, achieve control. If we had a NA engine, you wouldn't notice this taking place. Put your E47 program into a bone stock HHR SS , with a few parameters reset for gasoline, & the ECM will try it's best to deliver the same "torque-curve", that you have now, on E47, & you'll never feel it's trying to reset to a lower "torque-curve', as it will be constantly tring to reset to a much higher "torque-curve", that it will never achieve. I've done this, & it's really awesome. When driving my E47 "tune", on gasoline, it feels exactly the same as when on E47, up to at least half throttle. With just cruising around town, or going to work, it's the same..:twothumbs: The ECM is easily doing this, by smoothly increasing the boost. I tryed this, incase of a scenario, in which I didn't have access to Ethanol. It really makes sense, as it's the Ethanol that's giving us the awesome power & torque increase. |

Then with the example that I gave, it will be a "learn-up", & will never
reach the higher programmed, "torque-curve". Learn up or down, the ECM is just syncing it's tables, to best follow the programmed "torque-curve"...:twothumbs: If you do feel a nice increase in power with an ECM reset, it just means that your "tune", not as strong as it could be, there's room for improvement. |
