Dyno tune vs Email tune

So i feel like there is a lot of confusion regarding this subject, and since I'm at work on a Saturday with nothing better to do, I'm going to take a stab at clearing a few things up.

So, lets start out with the email tune. I understand everyone has their own views and opinions on these, and while i respect all of those, some of them are just plain wrong . I feel a lot of people get confused with what an actual email tune is vs a "canned tune."
A canned tune is step one of an email tune, a lot of people seem to think its all there is to it, but its simply a starting point. The reason these tunes can be "canned," "cookie cutter," ETC, is because pretty much every single car (v6 mustang in this case) with the same mods will operate within a certain range. Every single intake / off road X-pipe car, will be very close to the next. This is why you can be sent out a "cookie cutter" tune to get you started.
The steps that follow this, the datalogging, the back and forth via email, this is 100% a custom tune. When you datalog and send your tuner the information, it is the exact same procedure that is taking place on a dyno, there is literally no difference.

Next, we move on to a dyno tune. I dont want to make it sound like i am dogging dyno tunes, they certainly have their time and place, but i hate to break it to you, an all motor v6 on pump gas just is not it. The only benefit a dyno has over an email tune is that you can see where MBT is when dialing in the timing https://en.wikipedia.org/wiki/Maximum_brake_torque . While being a benefit of a dyno, this is not relevant to 99% of the people on this forum, and really is only an issue for the odd boosted scenario here and there. For the most part, every single bolt on car will behave pretty similar to the next.


I understand this thread really hasn't explained much so far, its just kind of made a few statements about what i believe to be true, but basically there are so many avenues this conversation could take, that im not even going to try to possibly cover them all. Instead, i want this to be a singular place of discussion for this topic. All questions, comments, and concerns should just be directed here, that way we dont spam other threads with tons of redundant information.

Just curious and idk if you have experience with both but figured you have an abundance of knowledge and wisdom on these cars. Why would MPT's tune feel more aggressive then others? Any idea what specific parameters might be changed and if their 93 Race tune is safe for a DD vs say Bama or Steeda's 93 tunes?

Sure, there's tons of things involved in making power, intake cam advance for low end torque, ignition advance, AFR ...

The beauty of these VVT motors is that you can really play around with the power band and get essentially "the best of both worlds." You can increase the intake cam down low for example, which increases dynamic compression (typically at the sake of airflow) which will build lots of low end torque. From there, you back that intake cam advance back out a little to get some more top end air flow for top end power. Depending on how each tuner decides to approach these events (as well as how they factor in ignition advance) can determine how each car will feel, put down power, etc... These cars also have an electric throttle body, which means its very easy to make the car feel more spunky just by adjusting the DBW (drive by wire) tables. For example, if you press the gas pedal down 5%, i can have the throttle blade open 20%. Not knocking MPT, because i have no idea if that's something they implement ( a simple data log of applied pedal position vs actual pedal position can tell you though) but its a very nifty way of "waking a car up."


As far as if these things are safe or not is concerned, there's a lot that goes into answering that, so for the sake of discussion lets just say as long as the car is not knocking or running lean that it is safe.

Actually I disagree with on road tuning being just the same as dyno tuning. First off, there are many variances in dyno's and how they are operated. There is no replacement for live on road tuning. Many times (coming from srt4 world a few platforms back) my dyno tune would run lean on the road with knock (which did not show on loaded dyno) and I had to add fuel. I know people will cry it's not safe etc. etc. But, bottom line it's the best. If your all caught up in drag racing then live logs from the track are the best. If you roll it on the hwy then logs from there are best. And this includes all the loading dynos (superflow, mustang) etc. Good luck...

You and i actually agree in that aspect, i have had cars run 25 psi on a dyno, then hit the street and are overboosting to 28 because the dyno was not loaded properly.

In this case, we're arguing two different things however. My initial comment was that the dyno operator, when writing a tune, is looking at the exact same information via the datalogging process and making changes based upon it, that an email tuner would be making. The accuracy of that information is another issue entirely

Not arguing Brother, just making a valid point. I've done them all. My personal opinion is "on road" is more accurate. But, it takes more time (sending in logs etc.) and is more dangerous (breaking the law) in the end. I think a good tuner/operator with a properly calibrated dyno will get you close on a loading dyno. This is second choice if you don't have the roads or time to do it right imo.

Maybe "discussing" was the more appropriate word to use , we're on the same page regarding on road tuning though.

I know there are just some people here who swear a dyno tune up and down. Thats fine, it may very well be what they prefer, believe is best, etc, i just want a thread where people can have all the information involved in making a decision like this.

It all depends on your setup. Everyone gets all wet over email tunes and a data log.
Funny honestly, but what do you expect lmao.

Yeah LMAO.

Funny the same guy on here who feels the need to express his opinions on most threads. Where do we start? "You got to mix things up if you want to be the fastest." I blew my motor on a 200 shot of nitrous...so naturally I'm an expert. I got 20k in mods in my car (Oh look at me) and another 20k to go. But, then you rant on about I'm going to sell it and buy a vette or a house. Who cares....

Hm, interesting read. Not that crap about them, but the info. Nice to have a general idea before getting a custom tune for my car.


Pick your poison.

I do really appreciate the "write up" Volt did, it gives a good insight on what may or may not be right for your individual situation.
