Engine tuning
 

Is it possible to tune a motor on a dyno ? And if so, would that be better than if the motor was in the car?

u can tune an engine on the dyno. its not better than in the car, on the dyno is only good for baselines and peak power. optimization is done by on track tuning.

Ah ok, thanks.

Running an engine in on a bench dyno is fine, maybe even getting some basic tuning outlines done would be good. For full power tuning it is best to do it in the car. An engine dyno is great, but sitting on the rollers and tuning the car while it is driving around is the way to dial in fuel and spark to account for the various loads it will see in the real world.

Yea thats what I kinda forgot you could do almost easier too.

No one really tunes LT1. So its hard to do a mail order tune using a dyno.

Say what?

And PCMforless has dyno days....

With a dyno you are tuning under a more controlled enviroment, but you're tuning just the engine, not the entire drive train, shift points etc. Plus when with the engine in the car your tuning with all your equipement installed, intake, fuel system ect so you get a truer tune, you'll know more about potential problems like going lean etc. I'd perfer an in the car final tune.

As far as mail order, unless your setup is something out of the ordinary the tuner will likely already have a tune for you car. In my case, I used a base tune, and sent the tuner a dyno sheet from TTP's dyno and a scan of the car being driven for them to make changes, not as good as havng it done in person, but the changes seem fine. I'l sure there is more in the car though. but that was a few years ago.

Us LT1 guys do have a local option = JSP. I talked with his tuner an I was very happy with what he had to say, so my car will be heading there in the spring once the stroker motor is back in.

JSP as in sponsor Josh?

Yes

I thought he only does mail order tunes?

He does LT1 and TPI tuning in house
