Dyno shop? Where?

Quick but rather stupid question........I think I should dyno tune my car, it's performing great, but think/feel that it has more to give than I'm getting. How can I find a local shop that will dyno tune my car? Will this help?

Go to DynoJet's web site. Sorry, I don't have th URL handy. The site will provide a list of local shops that have their chassis dyno. Call these local shops to see if they have someone who can dyno tune. The shop I go to for dyno runs to is a dedicated Viper shop. If someone wants a dyno tune (other than a Viper), they will rent the dyno by the hour for the tuner (that you bring with you) to do the tuning while they do the pulls. I bet some shops near you will probably do the tuning as well. My $.02.

Dyno tuning is great, but most things can't really be tuned. The computer will adapt to most changes you make. Base timing is probably one that you can tune on, though. The more valuable information would be what your power band is and trying to isolate what your bottlenecks are.

Here's a blurb from Ford Fuel Injection and Electronic Engine Control:

Drivers who driver their adaptive-system cars to the drag strip are often puzzled about their high elapsed times. The system adapts to street driving. When they run the strip a few times, the control module re-adapts to the strip, and their E.T.s improve.

A dyno is almost like doing runs on the strip. You may be changing things and your power is improving, but it may be nothing more than your computer adapting to all the WOT runs. The only way to really make sure that the changes you make are making a difference is to reset the computer before each run. This way you know that the computer is starting from the same base line each time.

Just in case Mach 1 reads this, the above quote clearly indicates that adaptive strategy even applies to open loop operation.

Oh, and here DynoJet Facilities in New York

Thanks guys, much appreciated. So, do you think it's really worth it? Is it expensive?

I got quoted $125 for an hour. Some places charge for a number of runs.

I'd say it's worth it for finding major bottlenecks in your engine and for getting a baseline. It would also be nice to find out what your exact power curve is so that you know when to shift. I don't think it would be good for making little tweaks here and there on a computer controlled vehicle.

I bet jimberg is right about computer controlled cars. Some outfits have the ability to burn custom computer chips though and so can change anything they want to. Of course they have to know what they're doing to help you any. Timing and fuel curve maps can be made better for performance and probably sacrificing some drivability and economy.
