Driving the car back from BG was a low point for me. The car felt like it was running like Sh*t. MPG was not very good IMO. There is a rhythm to a well tuned motor and the trip back from BG, it sounded like a out of control orchestra. Just didn't have that harmony. One of the things that has really
made this package sing is playing w the SA tables. More timing has brought it together. Adjusting the Accelerator Enrichment also helps with giving you that sense of being directly connected to the motor. You tune it to eliminate that count to 1 before you actually feel the response from the go pedal. At cruise now you get just a steady purr of the exhaust with no motor sound coming from the front end. Happy noise! So now the tuning is focused on things like getting rid of the annoying surging on decel for example. Little nit picks but since I don't need to live with it, I choose not to. ![]() With Part Throttle pretty well locked in, I'm looking forward to optimizing WOT. The cool thing about ECMs and tuning the ZR-1 is how you can create a Jekyll and Hyde car. A motor perfectly fine idling at 775-800rpm with little to indicate that there's a motor under there producing 500+ hp and 1/4 mile speeds of 120+. As the Octane Magazine describes it, the perfect Q ship. I love sleepers. Last edited by XfireZ51; 07-03-2011 at 11:09 AM. |
