i was wondering if anyone knows which tune is more efficient? is there a better way to go? any risks goin 1 way or another?

 

Your kidding me right? A dyno tune would be much more accurate and efficient! Street tunes are done when there isn't a dyno available or someone doesn't want to pay for dyno time. Some people can get away with a street tune but if you want it done right a dyno is the only way to go.

oh wow thanks.. i read on a shops website that the street tune is more accurate and that didnt sound right to me.. i had my car dyno tuned once but now i jus built my motor and was wondering wat way i shuld go.. thanks for ur help

 

Dont get me wrong street tunes can be good they just stink because you are on the street and you need to push the car so that can mean tickets and such... Street tunes depending on who it is can be great and can also be very time consuming now dyno time can be costly and may sometimes be time consuming. In my opinion if i had a choice of eithier or, it would definately be dyno time.

 

street tuning must be done for gas milage...

I ran all year on a street tune, worked good and had a good season with it..

 

I like to do street tune, dyno tune, then street tune again just to make sure everything is good with real world load.

 

dyno tune all the way

Exaclty what I was going to say. Every tune needs both.

Doesn't matter how life-like your dyno operates.. it will not be exactly reproduce the real world.

 

I always just street tune.

I usually try to find a strip of road long enough to rev all the way though 3rd without getting in trouble. Then once I get the idle/part throttle/wot through 3rd gear done, I take it to the drag strip and log a number of 1/4 mile runs and tune from there.

It's safer to tune at the drag strip than the streets. Plus it's flat and you can get some good WOT datalogs.

But if you have the $$ to rent out a dyno for a number of hours than I would think that would be even better than a street tune.

 

If it's a street car, where the majority of the driving is NOT done at WOT, then you need to street tune it to get the best drivability/mileage out of it. You should ideally tune all the non-WOT portions of the map on the street, and tune WOT on a dyno. If you can't afford both and it's a street car, get a competent tuner, do a street tune, and save your money for a dyno tune later on.

I disagree 100%. My car was NEVER street tuned and I have no drivability problems...in fact the car drives like it is stock. In fact last tank I got 29 mpg with plenty of WOT driving. When I was driving back from getting my tune (rougly 200 miles) I got 35 mpg. I think it depends on your tuner and what they are comfortable with and, if dyno tuned, what type of dyno is used.

 

bump this up for some more answers......


any of your guys tuners do a dyno tune THEN go out for a street tune to make final adjusments if needed???? do things tend to change once its off the dyno and on the street?

 

i personally like street tunes over dyno tunes...
onthe dyno you can get the most power out of it playing with timing... but you will never get real world **** on the dyno....
i have street tuned all my cars and have posted great #'s with them....

a combination of both is the way to go!

I agreee with the " do both if possible".
We did both on mine last week. Dynoed for a few hours then went out and street tuned for a bit. There were small changes from the dyno to the street and a few issues that were adjusted on the street. (you've also got the humidity and temp change as well) The car drove good before the retune, but drives great now. M. Brottle (TheMidasTouch on HT) did it for me and did an excellent job.

 

we tune every car on the dyno, then hit the streets for some finishing touches for driveability, decel, etc.

I rarely do wot pulls on the street any more. Just use the street for partial throttle / vacuum, decel, accel, etc.

 

Dyno tune then street tune to clean up the tune.

 

never had my car tuned on a dyno, just a wideband out in the nice humid streets of florida..... I would think that in places like florida a dyno tune would be off in when the dyno area is low 80's in temp and outside is close to 100 with equal humidity?

If it's tuned correctly. No. Dyno tuning is fine in the winter and summer

 

do most of your guys tuners cater to your needs?

example: if a customer wants a drag only car, then the vehicle will ONLY get a dyno tune.

but if the customer wants a daily driven turbo honda, then is that customer going to get BOTH a dyno tune and a Street tune or just Strictly a street tune?

i like to do the same thing, if its not a high horsepower setup street tune to get the A/F taken care of then hit the dyno to get the timing/torque taken care of aswell as playing with the A/F's to see if it makes changes, most people that try to start tuning right on the dyno spends so much time on the dyno just to get A/F's down and then run out of time to do the timing portion. thats just some case's ive seen.
but if your tires are gonna break loose while doing 3rd gear pulls take it to the dyno its not worth your or the customers life if they don't want to then tell them to take it to some one else.

If you get it done on a load bearing dyno, you can take care of pretty much all the load-conditions you're going to see on the street... without the risk of a ticket/accident/death, and also tune it for peak torque in partial throttle as well...

does servion always tune on a dyno dynamics????? if so then you dont take the car out for a little test run or street tun after its been dynoed???? or is there no need to since the dyno dynamics can apply all the real world road conditions??
