Superchips use,long term

[norsman]

Well it's been two tank fulls and my 3865 is working great on 91 0ct performance.Now I'm wondering am I doing any harm to my motor,I have my mds shut off and that really worked good but is that going to be a problem in the future?? I'm sure Dodge meant the mds to be working and now I'll stopped that.Some one told me he bent two valves using superchips,so is there any long term users on here to re leave my stress and fears.I just want to know that I can use this ,which is working well for a long time with out damaging my motor or trans .Any one a long time user???

Long time user here, even ran the old 3714. Ha ha, Wanna bend a rod use 87 Fuel with the 91 at or near sea level. As far as MDS goes those lifters are still moving are they not. I would not disable the MDS if it was me. On my Magnum I have a Crazy Spartan and Custom tuning using DSP and my MDS is there for the HWY and I get 27 MPG US at 65 MPH so IMO if you don!t want MDS put Mopar Non-MDS lifters and call it a day. Hope this helps but SC 3865 is great on our trucks DSP well after a week I sold it but then again I have an 03 and thats another story.

I've run SC3815 for the sole purpose of disabling the MDS and haven't had any issues. I've run it for going on 4 years and have 64k on my truck. Just had a powertrain inspection too.

No, you aren't harming your engine.

 

[norsman]

Thats what I want to here,really 4 yrs with SC and MDS disabled the hole time??What Tune are you running,performance, mileage,87 oct ??? No trans problems??you give me hope

 

[badblackram06]

I don't have a hemi but I do own a superchips. I have had mine on 91 octane for years running 91 octane and never had a single problem. And I don't necessarily baby mine. So as long as you keep the correct grade of fuel while at the same octane tune you will be fine.

Now with the mds. If is turned off I see no way it could mess anything up. The engine is actually functioning the way it is supposed to. But yet I have not heard any stories about mds messing up either. I just can't wrap my mind around a 6,000lb truck getting good fuel mileage with 4 cylinders. Maybe in a light car but not a truck.

Bent valves are usually caused by jumped timing or broken timing chain. Valves are always closed when the piston reaches top dead center. Jumped timing would cause a valve to not close at the right time making the piston slam into the valve therefor bending it. It's always good to get the timing chain replaced ever 100k or so and this won't normally happen.

Yep, no issues. I ran 91 for a while then went to 87 and been on it for a couple of years now, all with the MDS disabled. I never saw any gains with it enabled and plus it sounded horrible with the exhaust so I had to get rid of it.

 

[KGBIGCOUNTRY]

Bent a valve with SC???? Must have been an early 03 with broken springs and dropped 2 valves.

 

[Budakane]

been running one on mine since new...no issues.

 

[Budakane]

I run mine on 91 octane

New to tuners myself, If you run the 91 or 94 octane tune but fill with 87 octane gas could that give a risk to damage the engine?

The theory behind this is as following:

The different octane ratings have to do with engine knock, your engines computer ignites the mixture a number of degrees before the piston reaches top dead center (timing advance), long story made simple more timing advance is more power. However advancing the timing AND running low octane fuel can cause engine knock wich is the detonation of the fuel mixture at the wrong time.
Higher octane fuel is more knock resistant and allows you to advance the timing further theoretically allowing you to make more power.

From factory the engine timing is setup conservatively to run with lower octane fuels (so less timing advance), when you load a 94 octane tune, the tune will advance your timing more since you are supposed to run 94 octane now. The advance in timing will give you more power.

Now on the other hand the motor also has knock sensors wich can tell when the motor has 'knock', if they detect knock they will retard timing to get rid of the knoc and protect the motor, how far this system goes into protecting your motor I don't know,so to answer your question, IMO when running a 94 octane tune I'd run 94 octane fuel .

Disclaimer: got no training whatsoever in the automotive field so if I'm talking ******** here, please feel free to correct me

 

[Hemi450hp]

Everything you just said is correct. You do not want to run a lower octane fuel than your tune calls for. Knock sensors are there to help, but they do not guarantee that you wont have a serious engine failure if it detects knock.

As long as you run the correct octane fuel for the tune you are running, you should be good to go. I put alot of hard miles on my trucks, and I have never run anything but the most aggressive tune available.

 

[03MopaRamman]

Well said guys! Follow the recipe. It is said if you live at High elevation somewhat like where i am but there are higher places some say you can run 89 on the 91 tune and be good but I would never do that. If times get tough then at least on my Truck I can retune to 87 and be on my way, with my car I have custom tuning so wherever I am I pay the price. Furthest East wicked gas prices I seen were Regina Saskatchewan this summer at 1.39 a Litre (x 3.78 would be US $ equivalent...wow huh).

 

[Ramunit]

I've been running Superchips continuously since it came available for the Hemi in 2006, trans tune and TM reduction as well without a single issue, in fact if I were forced to go back to stock I would sell my truck.

94 Octane has been $1.50+ a litre recently where I live, luckily every time my local gas station drops their price to clear stock, they run out of everything else so I can usually get 94 at 87 prices.

Thanks for the info guys, I'm looking at getting a diablo trinity for myself for christmas so i'm trying to broaden my knowledge before i get it.

Using these tuners is very simple as long as you stick to the basics. If you have a basically stock truck, dont try to rev it to 7000rpms and always run the correct octane fuel that corresponds with the tune you selected. Do this, and you will not have any problems and your truck will be alot more fun to drive.

 

[KGBIGCOUNTRY]

^Ah come on 7K on stock springs always ends well (joke).

 

[03MopaRamman]

It is proven the stock block can Rev 6700 no probs (With bigger Cam and bee-hives at a minimum) and of course Superchips, but never noticed if it actually goes higher than my 6500 when selecting it.

Now the best Safety Option I like is selecting the 140 Mph top-end, that way if some thieving Basterd steels the Truck (I know that ain't gonna happen around here) they will be sure to meet their maker if they try to take her to the limit!

 

[KGBIGCOUNTRY]

Being an 03 not sure if it will do it or not. I know after we got my truck together it smacked the limiter at 7k when we were trying something. On the dyno we did a full pull with the top speed unlocked and when he let out of it she was humming over 140 on those poor NTG's (yes they are not rated for that nor did we notice the MPH.... we were watching A/F vs RMP and curves).
