Tuner Shops.

[Jason04srt4]

I just got a map clamp for my srt-4, and would like to get it tuned if I my fuel is running rich enough. Are there any shops in the area that can measure my A/F ratio on the street, and then install and tune map clamp if my fuel is rich enough. I prefer the street tune over the dyno tune because of the more accurate A/F #'s. I already have an extra bung hole in my downpipe.

Thanks

Might want to define "area" a little better. Later, QD.

Well, I live in gwinnett. I know a lot of the shops are in cobb. That is cool with me. I like to drive.

what makes you think that street tune is better than dyno? the roller simulates laod on the chassis and engine just as effectivley as a street tune. Plus, its much easier to do FULL 4th gear pulls legally on a dyno than on the street, and much safer.

we had a SRT4 over here a few weeks ago that had a turbo and intercooler and we made 423whp on it with race gas.

We charge $100/hour on the dyno. we have street tuned and dyno tuned lots of cars, we wont street tune anymore because of liability and its just not safe and its not as effective.

You need a loaded dyno like a mustang or a dyno dynamics to simulate the full weight of the car. A dynojet basically you are just accelereating against the weight of the two big roller drums which are not even close to the true weight of the car unless its a very light car. tuning on a dynojet works but i'd always put a safety margin in the tune just to be safe especially when tuning on pump gas.

A street tuned car will always be better imo. You drive the car in the real world not the dyno room.

i used to believe that too because that's what everyone said...however, i originally street tuned my car and the afr were nearly identical on the dynojet. that's when i decided to not street tune anymore due to safety, liability, etc.

yeah,i think it depends on the car. Like i said i'd always tune it a little bit richer on a typical dynojet when using pump gas especially on F/I cars.

[Vteckidd]

while i agree with your point Windsor, how much whp are we REALLY talking about? not alot IMO. i have seen street tuned cars come in here and make almost the same a/f ratios on the dynojet.

My point is, ESPECIALLY for F/I cars, its MUCH harder to tune a car on the street and do FULL 4th gear pulls where you can be at upwards of 120mph on the street. its just not safe and practical IMO. on the dyno you get the advantage of tuning all columns and rpm bands and there is no consequence from johnny law or other motorists.

Also, street tuned cars you cant tell where to put vtec for hondas (NOT ACCURATELY) , you cant play with cam gears, you cant see whp or Tq gains or losses. its all "flying blind". all your doing is setting the car to a certain a/f ratio taht you want. that is not TUNING IMO, thats a BASEMAP, a very spcific base map, but a basemap nonetheless.

how do you know if your car is making power whether its rich or lean. lets say you pick 13.5:1 for your na car for your target A/F ratio. now, you cannot go lean or rich and see if the motor likes it and see if it made a difference on the street. same with boosted cars.

I have seen people try and "street" tune and it usually ends up with very dissapointed customers and tuners have to deal with dangerous situations of high mph and traffic congested areas. Think about this, an average street tune is $75/hr. well we cahrge $100/hr on the dyno. i think its worth the extra $25/hr IMO.

in closing, conrad=wrong
just kidding buddy. i see your point, and maybe in much higher whp applications and heavier chassis's it does make a difference.

Well, I've been told that the added air flowing across my intercooler at high speeds will lean out the car. Anyways, looks like I will settle for the dyno tune. I want to know what kind of #'s i'm putting down. If my fuel is rich enough can you soder the map clamp to the map sensor, and tune it. If my fuel isn't rich enough I will have to wait till I can get a fuel return line.

Thanks

we had a guy with an SRT4 make mid 400whp on his, he switched to a return line style and made 423whp and his a/f ratios where much cleaner.

street tuning is great for doing your drivability tuning, but for power pulls you can't argue that the dyno isn't the place to do it. like mike said, just tuning for a certain A/F isn't necessarily going to make power... and how are you supposed to tell the change in the torque curve due to timing changes on the street? the ass-dyno isn't that accurate, i promise you.

we set up VERY large high flowing fans in front of the fmic. you'll have plenty of air going across/through it.

you won't be disappointed.
