I'm gonna correct on that having someone tune for s.d is no easy task if it was everyone would offer this service..S.d is very tricky and you need to understand ve and other tables...The best way to wire up the ait sensor is to wire it straight to the ecu for accurate readings or the new spooling up harness.

My friend was tuned on s.d and the car drove like crap not smooth and the car wouldn't hold steady afr's till redline, not only that but the car had cold start issues..He drove to n.y.c to have urkel retune his from scratch using urkels base map from scratch, and the car woke up it spooled faster and in between shifts there no falling on it's face just smooth power and cool flames on throttle let off..

My friend called me the other day and told me he gets almost 28 mpg not bad for a 545 daily driver lol..Fyi there's only 4 people in the evo community that can tune s.d and that's ,john bradley,diirk,bryan gst,and non only but urkel..

Im getting tuned at ptuning in manassas va and they have great knowledge on sd setups and their the reason im doing it. Also the omni power plugs to the stock harness so I assume its connected to the edu.

why do you feel the need to speak...4 people huh..wow.

Touch down for ignorance!

You get today's most uneducated post award. They are the 4 most common SD tuners that you will see time after time again.

E-Spec congrats on the numbers. I am helping a friend try to achieve the 500whp mark on the back and 92 octane. I am now convinced it won't be as hard as I imagined.

Because i'm right about what I said..Can you name more people on the evo m community that can tune s.d and do it right??

You mean most educated that lesson was for free..

Yeah I can how about the other big names i.e..David buschur, STM and just about any other shop on this board? The whole speed density is not a new thing been around for awhile so don't act like one side shops mess up mean only a handful of people can tune sd setups.

Really stm.emery doesn't tune s.d and is not a big fan of the stock ecu ,maybe david but not stm..

He can but loves the AEM ems lol all of shops pretty much can do it and have the knowledge and not mess up small shops now.they are ones to worry about.

Theres enough information on this forum to allow anyone to tune SD. Look at Scheides guide. The information is practically spoon fed to you. Its a very good guide.
There are a lot of people on this forum that can setup SD, not just vendors.

Look at the info on this forum and you will see no vendors helped decompile hex code from the rom or decipher any of the coding. If you search this forum you will see all the people mainly responsible for what we have today to work with (All sporting an EvoM Guru red badge under their names). Back in the day people had to open roms in hex editors and edit the hex just to edit the maps and didnt even know injector scaling was possible or any of the new stuff we have this day and age.

Just because someone owns a shop and is successful doesn't mean they know more then someone else that doesn't own a shop and doesn't profit off the same thing.. remember that. Some people have more interest in certain things, therefore they will teach themselves every aspect of that specific thing, while others may not put as much time and effort into it. with that said, E-Spec tunes a lot of cars on SD and I would personally take my car there if I was in there area and was looking for a SD tune/conversion and didn't want to do it myself. So there you go for NY people wanting SD go to E-spec if you want it done by a shop.

We called top speed,the shop,fid ,ams,mellon,jester,4ws,top level,ivey tune,forged performance,and some others either they say no,not worth it,it's a fad,you don't need it,by the time you tune it you can buy a aem,or leave your car for 3 days for it to be done for it to be right..Any way good luck with your s.d tune..

I will and thanks but it is a all day affair. But a good tune always is then I also get a road tune to make sure that's why I like this shop Dyno tune then street tune.

Very true tom but how is the tune gonns be and feel overall??In reality when they say my s.d tune is so smooth that means they never really had a good tune from the beginning even with the stock maf cause my car ran almost just as smooth with it as it did on s.d...Look at the tune you just did it's all in the tuner..

The only thing you cant take away from what SD does is it removes a restrictive maf which will result in 10-20whp 90% of the time. I was going to do it to my own evo but decided against it for now. Also bov to atmosphere will assist in better throttle response as well.. anything restrictive will effect the overall charactorists how the evo acts and responds once removed.

Do not get SD done by a remote tuner it must be done in person.
If you're gonna let a shop do it the only shops I can recommend to do it if you're local to them are AWD motorsports (FL), GST motorsports (Cali), E-spec (NY), English Racing (WA), Not sure who else im forgetting but I apologize. CBRD (PA) can also do it if Chad calls his friend Kreionic in to do it.

Very well put I see someone agrees with the people I MENTIONED.
