Dyno tunning

[big john 02]

Ok so who has done it or is everyone just going with the hemifever or canned tunes? And if you have done it what did you get outta of it?

This just comes down to finding a local shop that has experience with the hemi trucks. Very few shops know what they are doing when it comes to the hemi motor...and the ones that can tune the motor, usually dont have much experience when it comes to the transmission and tq management.

So many people go with Hemifever simply because he is 1 of the most experienced hemi tuners in the country and has tuned thousands of these trucks.

If you can find a local shop that has some experience with these trucks though, there is nothing at all wrong with letting them tune it for you on the dyno.

I have a shop a couple hours away, so sorta local, that does a lot of late model mopars. Would there be benefit of having the vehicle dyno tuned over doing data logs and such over email? I have a custom tune from someone on here (not hemifever) and have been pretty happy with it, but wonder if there is a little more to be had by dyno tuning.

Im gonna say , not worth it until you decide to go F/I or tear into the motor. The guys on here are very good at what they can do. Plus they can help you again and again without either of you going out of your way. I for one have been VERY happy working with them.

Best thing to do is grab the tuner from Moe's Performance

Throw on the Hemi Fever 93 tune and see how you like it.

Then get the dyno with and with out.

Based on personal experience I think you will be shocked at the difference

nothing to lose here, if for some reason you are not happy have him throw a tune on it

at least you will have a stock and HF93 baseline to measure the value of his results with .

I doubt it. The dyno is a good tool, but if you already have a custom tune from an experienced hemi tuner, then I would be surprised if you gained anything noticeable from a local shop on the dyno.

Actually, if you have the time, tuning via datalogging and tweaking, I've found, is a much better avenue. I did this with my mustang and, although it took more time than a dyno would've taken, it worked out much better in the end. The up-side to datalogging on the road is that you are getting real world information on how your drivetrain is actually being loaded when you're driving. A dyno simulates that, and pretty well, so I'm not knocking dynos at all, but there's nothing quite like the real thing.

I used Delta Force Special Forces software to do my mustang, so I didn't have to sit around and wait for someone somewhere else to tweak my tune after each datalog (that could add a lot of time), but I'm not sure if that software is compatible with Mopar stuff.

All that being said, a canned tune can usually get you pretty close and you can datalog from there to fine tune.

The one downside to datalogging on the road is you need to have a nice long straight and level road, and you need to just accept the fact that you're going to exceed the speed limit... by a lot... and more than once.

...experience when it comes to the transmission and tq management...

I'd like to know more about this!

Dyno Tune

For what it's worth I had my 2004 to a speed shop to be dyno tuned back in 2009. They never got it dialed in but, Hemifever did over the internet!!! They had tons of experience with Ford's and Chevy's and "claimed" to have had good results for their MoPar customers. Well that was just ********! I will say their shop and facilities looked very impressive when I dropped my truck off. But, our Ram's are a totally different animal and I found out the hard way that knowledgeable tuners for are trucks are in short supply! After a few data logs Hemifever had it running great.

From my .02 coming from doing both dyno tuned vehicles and utilizing tuning software written from someone miles and miles away the 2 key things that come into play is complexity of the builds.... Taking a motor that just has bolt ons its not worth the cost to dynotune it, your not going to see any big gains if any at all over going with HemiFever or such.
Now if the motor is beyond bolt ons and has custom parts and such then maybe, but a knowledgeable person like Hemifever is who you want to talk to.

^^^This. My 'stang that I datalogged and tuned on the street was fully built, stroked, high compression, aftermarket everything. I never would've bothered with that kind of tuning just for bolt ons. For bolt ons just get a canned tune, datalog a run, send it to your tuner, have them tweak it, and reload the newer version. It'll probably be perfect in one or two tries.

My 02.

my experience with my charger was quite extensive and I learned a lot.
I began using diablotoona via e-mail and every time I changed a major component or did a rebuild I sent him logs and he sent me refreshed tunes. whenI did a rebuild( cam heads long tubes blah blah) he sent me a nice safe starter tune, then dialed it ion as I sent him logs. Pretty common approach. the benefit of email tuning is that you can datalog specific events such as autodrive or surging or when the car falls on its nose. drivability issues can be resolved enhanced etc. in this manner.
My intent was to eventually get a dyno tune, but I planned on waiting until I was done modding, as I figured no sense getting a dyno tune and then changing a cam for instance, then starting over.
That may have ben cool to show progress, but my ET slips and butt dyno took care of that for a lot less money and more fun.
Once I locked in my build I went to DTP racing in Va beach Va. and had Brent do a dyno tune. I had some minor issues that I wanted addressed and a little drop in power around 5200-5400 rpm, that was killing my ET. The car was already a beast, and Brent found 20 more RWHP. He also test drove the car and fixed a those minor issues.
Brent also does e-mail tuning so I strongly recommend trying to find a dyno tuner who also does email tuning.

Another point is , if you go ******* like I did, Diablotoona and my builders, Dave Webber for the engine and paramount performance for the tranny and TC, all comunicted about the project. . This ensured good starting point with the tune and the correct stall in the TC. so If you can arrange for open communication its a plus.

As to my ram, I don't expect to go any further than I have so I'm all set with the Hemifever tune...... unless I star thinking about cam phase limiters and bump sticks long tube headers etc. for the Ram

which could be any minute

You guys need better dyno operators,my dyno guy datalogged my truck for over an hour before it even went on the dyno.He datalogs every vehicle before putting it on the dyno,if your dyno guy isn't datalogging ,find another dyno outfit.
How come none of you guys with either a Greene tune or a Powell tune never do a back to back test at the track to actually see what the e-mail tunes are adding over and above the canned tunes,that one has always puzzled me,

 

[Hemi450hp]

Plenty of people have compared them to their canned tunes at the track, but everyone always posts their fastest time (which is always with the custom tune).

Just curious, but what kind of numbers are you seeing on motor and on the bottle? And what is your current mod list? I dont think I've ever seen you post a timeslip.

 

[Wild one]

Corrected 12.9's off the bottle,and 12.1's at 110mph on a 75 shot,with a 3.21 geared 4X4 rcsb 14.Don't do pics,as I can look at the time slip whenever I want.Trucks fast enough on a 75 shot to make Kurtis worried,it'll run corrected 11's if I step it up to a 100,lol.It runs 12.7's at 3700 ft uncorrected
That's still not cutting it Matt,somebody must have a back to back comparision between the e-mail tunes and the canned tunes.
Blow the video up and hit pause,you'll see the numbers,the da was 3756 ft on that pass

Not to add to the fire nor argue with anyone but my father in-law has hemifever and is thinking of switching to jay after seeing and feeling how my truck is with jay's tune vs his with hemifever .

Very nice. I wasnt taking a jab at you...I just had never seen you post any times. Your truck is running very strong. What mods do you have besides the tune and nitrous?

Have him contact me if he wants an aggressive street tune. Not everybody wants that so he'll need to ask or mention it and I'll turn it up.
