I have tried searching but it appears that the search function is down hence i am sorry if this is a repost.

The city i live in is quite small with very limited tuners having access to a dynos. I inquired with a local shop which can do a "street tune" using ECtune. However, the concept of a "street tune" is very new to me and i have very little knowledge about it. What he explains to me is that he installs a wideband and does passes on the street rather than the dyno and keeps readjusting the maps until optimal settings are achived. Is this ideal? Can a good tune be achieved using a "street tune"?

Also, i currently have a JDM B18C (ITR motor) with the stock JDM ECU and basic bolt ons, I/H/E, will i see good gaines with a tune? Or should i wait until i have more mods (cams/valvetrain) before doing a tune?

Thanks.

 

Some guy in my town told me a street tune is better then a dyno tune... Is this true?

 

Personally i would wait untill you have more mods. . I think i squeezed an extra 12 or 14hp out of my B16 with I/H/E /Intake mani/ Throttle body, By dyno tuning it .. . .

 

Im Interested in knowing more about this ? ANYONE ? ??

i personally prefer a dyno tune..i have friends to say street tune is better than dyno tune, but i disagree...when its dyno tuned, they usually do a 4th gear pull, and if u did this on the street, then u have the risk of an accident,its not safe,plus hassle by the po po, ...everybody i kno that street tunes theres, is still in the process of tuning it lmao...they are always going back and re adjusting, but maybe thats just because they are street tuning themselves and they think they are certified tuners haha

 

When street tuning it's harder to tune your ignition map, because you don't know what kind of torque your making on the street. So makes it more of a guessing game

 

Unless you have a load bearing dyno, then a 4th gear pull is only tuning WOT. A street tune will cover more maps that have more load on them usually. Especially if you can go up hills and such in a higher gear to make the car work harder and put the zones in a different part of the map.

Load dynos can put a 'load' on the car in a safe environment and allow tuning over more of the map then just a 1 gear pull.

 

I use to do street tuning primarily a few years back. Now that we have a dyna pack 3000, I hardly ever do any street tunes. Only to touch up part throttle, like fuel cut which is tough to get even on a load bearing dyno.

You just can't tune the car as well on the street as you could on the dyno.

For example, this kinda of stuff happens all the time.

Customer comes in with the air fitler pushed the WHOLE way to the end of the pipe, basically closing off half the filter so it only breathes from the very end. If you are just street tuning the car, you won't notice the power difference immeadiately. But if you are using a dyno you will see the 15-20+ hp loss and KNOW something is going on right away.

There are just too many things you have to worry about while street tuning, especially if you are in it to tune a bunch of cars. More specifically like cops, traffic, retard drivers, and faulty brake/suspension setups that could put you at risk.

But if you are tuning it yourself. It isn't a bad idea to get all of the a/f worked out on the street, especially the part throttle parts of the map. Then take the car for a few pulls on the dyno to work out some of the ignition values. This will save you some time and money when you are at the dyno.

Just my .02 cents from progressing from street tuning myself to basically running a dyno all day now.

 

Good advice right there from someone that knows ^

Plus I live in the desert which sucks (flat) and is cool (open highways) so I can drive 15mph in a 70 zone or I can drive 110 for 10 miles no probs.

But I still try to get to our local mustang dyno when the A/F are done. Plus thats all we have in a 2-3 hour radius of here and he doesn't tune. he just bought a dyno.

 

X2 good info 93 turbo...

Im still a noob street tuning my own turbo cars... but you gotta do what you gotta do, I have NO access to a dyno. NV has more legal prostution/gambling than tuners/dynos LOL so Im on my own! Street tune FTW.....

 

Read alot on plug reading. And buy some 1.00 each autolite. That would be the best way to tell what ignition timing and heat is being developed inside your engine.

It is safer to know that you may be too close to the edge and back it off then to get right to peak power.

Fuel is one thing. Timing is a whole nother can of worms.
