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? |

I think Chris captured what I'm after (not max power at the expense of fuel economy and longevity). I do want to keep my heat as I drive the car from early spring until early winter, but I'm ok with sacrificing some performance for greater comfort.
I see that the LC-1 wideband O2 controller with sensor and guage is available for about $209 here. Edit: I found one for $169 with the red digital gauge. Are there target A/F ratios for these motors at idle, cruise, WOT? I assume different configuations have different target numbers. |
