Have you done your research?
Have you run a Superchips for any length of time ?
I have for 3 years and there is a difference on premium when properly tuned for it.
The speedo limiter does make a difference on the highway for passing.
The rev limiter only raises the limit to redline, not to over rev.
Throttle response does not increase power just reduces throttle lag.
Superchips does offer Dyno charts for those interested.
If these tuners did not work they wouldn't be the most popular tuner for the 3.8L.
So, to the OP, it's your choice. I like my Superchips and won't run without it.
Yes, I have done my research and know how an ICE works.
Im glad you have run it for 3 years. How much HP and torque did you gain? Like I said I like to see proof before I drop $380 bucks on something a company "tests" I work in a testing lab and have seen cases where when a company tests their own product the numbers are tweaked and not actually what happens in real life.
as for the speedo limiter you go over 100 to pass someone? Thats a little fast I would think.
My jeeps rev limiter is already at redline as with most so why be able to change that?
Never said throttle response increases power.
As for dyno charts I said above I have seen companies fudge with those numbers. Where is the third party testing? Again I like real proof. Not marketing hearsay.
These tuners work because people dont do their research. If I paid $380 bucks to a company for something that should make my jeep faster it sure would seem faster to me, even though its probably not even noticeable.
So, my request still stands to anyone. I would love to see some third party results on said tuner before I throw even $100 at it.
If you run your current factory tune with premium you are 100% correct, however, running a tune specific to higher octane makes all the difference. In the old days on a manually timed engine we simply cranked the distributor to advance or retard the timing to suit the fuel we run. Even an 8.5:1 compression engine will show gains with premium fuel when tuned for it, specifically torque. High octane fuel burns slower and produces more power, (longer push, pushing the piston to the bottom of the stroke) but the engine has to be timed properly for the slower burn.
A good analogy would be the difference between modern gun powder and black powder.
Your two points here contradict themselves. Black powder burns really slow compared to modern gunpowder. So according to the first bold you should get more power out of regular, no?
You talk about gains but still do not site any information.
As to the link you posted, here is the quote your referring to:
Modern engines are designed for some rather high air-fuel mix pressure, if the mix ignites before that pressure is reached the engine just won't work right, because ignition will happen at the wrong moment of the engine cycle. That's why only fuel with right "octane number" should be used for any engine - depending on how that engine is designed, otherwise it just won't work right. The vehicle manual usually specifies which "octane number" is right for that vehicle engine.
You cannot change the compression ratio without changing the internals, and that is what that article is talking about. Your engine should be detonating the fuel air mixture when it is as close to fully compressed as possible and that compression is the same no matter where your timing is at.
I agree with JTPhoto i have also run superchips for years and can attest to that.
COLOUXJ - take it down a notch he's not Superchips first customer. it sounds like you drive a smart car
I am not being mean, I just do not like when people spew information that is not true. I know he is not superchips first customer. I bought their flashcal to correct for my 35's and the gears im getting in october.
This is a forum where you can share information and that is what im doing. I am providing a counterpoint to someone claiming gains, because I have done my research about it. Still cannot find any proof of any gains from anyone but Superchips themselves.
