I want to mazimize the tuning of my carb'd 2056. Short of seat-of-the pants tuning, I figure using a chassis dyno is the way to go. I haven't checked to see where the nearest one is or how much it will be, but after spending all this time and money building it, I'd hate to leave any power on the table. I'm just not sure how you go about using it to tune the engine.
I assume I should have the engine pretty well broken in and running well with the carbs jetted as good as my seat-of-the-pants dyno can tell. Do I go there with a variety of idle and main jets, air correctors, venturis, etc and start swapping things out one at a time based on a baseline run? |

wide open throttle power
Also tuning fi with a ecu is a lot quicker than carbs. You can drive and data log on a digital fuel injection ecu controlled motor. The dyno will only record that dynos hp and torqus numbers and it will vary between dynos. Also if the tires slip on the rollers it will be misleading. |
