I'm installing the beta KitCarlson FI and I'm turning my attention to tuning. I have access to a wide band O2 sensor setup for tuning in the FI part of the setup, but I'm not exactly sure how to optimize the ignition. My initial assumption is to install an EGT gauge. I would think this coupled with knowing the AFR would clue me into the ignition. There are so many factors I can modify that I'm having trouble keeping it all straight. Help me figure out what I need to do to get it well tuned. (IMG:style_emoticons/default/pray.gif)

QUOTE I THINK THE DYNO IS A MUST. kind of, seat of pants is a close second. regular dynojet dynos arent really helpful tuning tools, you need to find a dyno that can hold load againt the wheels. Bring the car to a given RPM, adjust the fuel, dial some load into the dyno and advance the timing until the power drops off, then retard the timing a few degrees back to be in power, and give some room so you dont worry about knock. With a good nock sensor you just dial the timing to max power, and hope the knock sensor works as well as it supposed to. You can repeat this process at every cell. Or establish tuning in a few cells, then look for trends in the graphs and adjust the other cells to suit. We spent hours tuning my friends 935 clone on the dyno, yet we still make adjustments at nearly every track event. |
