simontempler Posted October 12, 2008 Share Posted October 12, 2008 First off, I'm a noob at this - data logging, tuning and all - which is increasingly gaining my attention and a growing itch to try it. what I would like to know is, are there significant differences in the tunes? Is one tuned for DD and the other for extracting max power? Need input please. Thx. Link to comment Share on other sites More sharing options...
Infamous1 Posted October 12, 2008 Share Posted October 12, 2008 Road tuning is best imho because it is out in the elements in which the car will see. On a dyno the load is artificial among other things, the downside to road tuning is if you are not careful it could be much more dangerous.

Prime Power Posted October 12, 2008 Share Posted October 12, 2008 My avalanche is at the tuner and he does both. He dyno tunes it then takes it for a ride and fine tunes it out there to where he likes it. Link to comment Share on other sites More sharing options...
urs1ne Posted October 12, 2008 Share Posted October 12, 2008 Thats how Bill from I-Speed does it, on the dyno first and then around town to perfect it. ^ n00bs below this line Link to comment Share on other sites More sharing options...
simontempler Posted October 12, 2008 Author Share Posted October 12, 2008 Is it possible to achieve a smooth tune just from a dyno tune? Is doing the dyno first then road the proper approach to reaching the 'ideal' tune? On a road tune only, are max power gains achieved or is it best to attain them from the dyno? sorry, my mind is scattered all over the place... my uh, stocks kinda tanked lately.

mwiener2 Posted October 12, 2008 Share Posted October 12, 2008 A dyno tune will yield a higher output and a safer tune. A road tune will yield a tune with better around-town driveability. Most good tuners will dyno tune, followed by a little road tunning to smooth things out.

Boostjunkie Posted October 13, 2008 Share Posted October 13, 2008 I always tune the car on the dyno and make fine adjustments on the street. Tuning on the dyno allows me to see the small (but cumulative gains from small changes) and verifying the tune on the street allows me to see that the tune is stable and predictable under the conditions you drive in every day.

jamal Posted October 13, 2008 Share Posted October 13, 2008 Road tuning is best imho I take it you don't do much dyno tuning. Regardless I think the tuner is much more important than the equipment or lack thereof. Link to comment Share on other sites More sharing options...

simontempler Posted October 17, 2008 Author Share Posted October 17, 2008 Is it possible to attain a very smooth DD tune on just a Dyno tune? Or is that unrealistic? Link to comment Share on other sites More sharing options...
Infamous1 Posted October 17, 2008 Share Posted October 17, 2008 Is it possible to attain a very smooth DD tune on just a Dyno tune? Or is that unrealistic? Yes, completely possible as long as your tuner knows what he is doing. Link to comment Share on other sites More sharing options...
Sarg Posted October 28, 2008 Share Posted October 28, 2008 The nice part about dyno tuning is that on a load dyno, you can hold the rpms while at 100% throttle at a certain specific rpm and load point in the map. This enables you to make changes and see exactly what gains you get in each particular cell of a map. This IMHO enables you to get the most out of a tune. I think both have their places. Since I don't have free access to a dyno, I mainly road tune and I seem to get some results pretty close to the professional tuners who use the dyno, but if you want to squeek out every last inch of hp, the dyno is very helpful.
