Street Tuning or Dyno Tune
Hey guys, i have a honda del sol with a turbo setup, and was weighing my options between dyno and street tuning.
I was wondering if there are any street tuners out there. LEt me know asap, i really need a tune. Thanks.

It would be good to start off with the street tune, and if you really want to get max power gains, then do some dyno tuning. Dyno time can get real expensive fast, but if you already have a good street tune done, you will save alot of time on the dyno.

With a dyno tune, you can see exactly how much power you are making and see what you are gaining (or losing) with each change you make...
With street tuning, you don't have the ability to see right in front of you how much power your making and where your gaining/losing power.
It takes a little more skill to street tune a car.
When I get my cams, springs & retainers, cam gears, shaved head, itb's, and a good header, I'll be taking it to zeeman for a street tune. Then maybe later I'll hit the dyno and see if I can gain some more.
I have done a street tune on my friends mk1 mr2 supercharged that we race in autocross with using megasquirt. For my first street tune, it runs pretty damn good...
....yeah thats right.....I said "itb's"

That's like saying it takes more skill to remove spark plugs with a hammer.

Dyno tuning FTW!
- safer
- no law breaking
- repeatable results
- you can test various things to see if they make a difference (i.e. cam gear tuning, timing, richer/leaner mixture, etc.)
- you get a nice pretty graph at the end
I use u2ndyno because Dan's dyno (Dynapack) is probably the best/safest one out there. No straps to break... Plus he comes out to you!
Check out Defcon-ART and they will be able to check your setup *before* spending money on tuning... whether it be street or dyno. Nothing is worse that dynoing a car that isn't setup correctly. Not saying that yours isn't, just a second opinion is always nice.

so you'll be running right at WOT, but what about partial throttle or cruising? Guess the basemap is good enough for 95% of your driving eh.
Id rather street tune then dynotune anyday.

so why pay money to go on the dyno if you can do it on the street for free?
Dyno tuning isn't cheap, IMO it shouldnt be used to replace a street tune. I know your trying to get Dan business, or you are affiliated with him but if I was to go dyno tuning, it would be to make some numbers and see what makes me more power.
A street tune is not about making power, its about making the setup safe to drive, there is no need for a dyno for that.

I'm just saying that you can tune part throttle accurately and safely on a dyno.

Dynapack can come very close but a full tune should include a street tune or test to see how the car reacts.
A decent street tune should be done before a dyno session to save time on the dyno, IMO.
yes it can get illegal real easy and dangerous as well, but look at what were talking here... buiding motors/cars and making more power than the cars were intended for, of course we have to expect the legality and safety factors are gonna change to some degree.

I guess it just boils down to what your definition of "tuned" is.
Just because a car drives and feels okay on the street does not mean it's tuned. On the street, how do you know if there is 20ft/lbs of torque to be found between 3500 and 4000rpm? How do you know you are not over advanced at 5500rpm?
The truth of the matter is you guys are just plugging in a basemap and cruising around checking AFR's with your LM1...and while I will agree this is important to do...the end result is NOT a tuned car.

like you said depends on your deff of tuned.
Its obvious that a street tune isnt for power.
If a car drives and feels ok on the street AND the afr is good, your ign is safe, & no knock... thats tuned, no matter what way you spell it, to me. is it tuned for power no, but the car is driveable and reliable.
I agree a dyno tune is a must for power, but for just making your car safe you can do that with a street tune, would i street tune a 300whp+ car? not for WOT but for partial yes.
When i built my motor back east i was lucky to have a friend that had a shop and a dyno so all i had to do was build motor, drop it in, start, change oil, then put it right on the dyno. I agree that is the best way to do it but someone that builds a car in there home garage and then just street tunes it will be fine. Then when they have the time and $ take it on the dyno and go for power.
Sorry thats not helping you get customers but its the truth.
