04 2500 ram hemi- need programming help

[ondemandceo]

Predator U7137x for 03-08 dodge rams. I have a 2004 dodge ram 2500 with the hemi. I have added a airaide cold air intake system and flowmaster 50 series muffler. I wand to fine tune the predator for the mods I have done.I want to get every bit of hp, tq, and mpg I can out of the truck. What parimeters do I adjust and what do I adjust them to. I am new to this whole programming thing. I appreciate the help.

Those are just basic add-ons. They don't really increase flow or anything, so the canned tune will be fine for your truck.

[slickfitz]

If thats the case why do you offer CAI tunes with cars..ex charger 300c challangers ..etc

[Mike_Levy]

Because on the cars, they lean out mixture. That doesn't happen on the trucks.

With all due respect Mike, I disagree.
I own a 2006 Ram 1500 4x4 5.7 Hemi Gen II, I love the Airaid 300-220 MXP. It makes a real nice difference on my Truck. I also have Gibson Sport Duels exhaust. Defiantly breaths better. It has Tow Haul Factory upgrade. It will turn 5th gear and 4th gear OD off, one at a time and firm shifts up. Also it turns off MDS system. Button on shifter end. I have a Super Chip Cortex on that truck set on 91CAI tune. It will monitor quite a few parameters. I run 93 octane Sonoco. 180* stat also. It will bark tires on its 9 1/4 3.92 diff posi pretty good 1st to 2nd. Never did that stock. Dodge has Laws to follow for Noise levels Intake and Exhaust. Those 4 mods are the cheapest power you can bolt on that members 2500 Ram. 180 thermostat get that inlet air, engine and trans temp down. More timing curve with out ignition Knock. You need at least 180* to keep moisture cooked out of your oil. Any cooler is trouble for your Pollution controls too. I have no lights lit on dash. It runs at 185* with AC on or off, pulling trailer or not. If you don't have the MXP Air Aid air box your CAI system is not that great. My IAT (inlet air temp) stays about 2 to 5 degrees above out side air temp. Thats a Cold air intake. I started out with Air Aid JR kit I put on it. Little Better flow same Warm to Hot stock air temps. They sell the MXP air Box and filter separate. I came back and added that. It made the difference in air temp and flow. What ever your running check to see where that air temp is at. Read in this forum for all this know how. Your Diablo will real time track many things, record and put on LapTop screen in nice Dash format. A stock air box is better than an open under hood filter sucking radiator air and engine heat. If you can match out side air temp moving, not sitting idling, you are on the right track. Better flow in and out with Good Cat Back System and CAI makes those canned tunes Bark 33" rubber in 2nd with a 5 spd slush box on a 5500 lb truck. Let your truck adjust those fuel air ratios. If you dont know what your doing there you can run lean, thats bad. You haven't done anything your trucks ECM wont balance out correctly. Make sure you pull either Battery ground or better the fuse to the ECM let it reset with new mods. Pull Fuse at bed time and pop back in going out next day. From time to time its good practice to reset as it will conform to everyday driving. Go fast, and reset go together. Throttle pedal adjust, turn key to on, dont start. Mash pedal to floor all the way 3 times. Turn key off then crank. You will notice better wireless throttle responce. They need that every few weeks or months. Your truck is heavy. Be realestic in your expectations unless you have big thick wallet. Or, buy a Challenger R/T. Or Charger R/T's. I did all 3. Love them all. My Ram and Challenger compete for upgrades. Wifes Charger is a hell of a nice ride. Road and Track Package R/T, Loaded. Stock 350HP. Big fast comfortable nice car. Im 6'2". I grew up a Mopar kid. In the Muscle Car days. Do it right, you can make that 2500 Rock. 450 HP safely.

Diablo Pedator Best tuner on the market. My Challenger has Diablo. But Ill be adding a lot more than the current mods. Later. For now those canned tunes are great. Im the guy that wrote to Mike_Levy above. Once you go beyond CAI, Put Good Cat Back duels on your truck, Diablo tune, 180 stat. Things like Cam, Heads, Long tube Headers. Nitrous then you need a good Dyno tune. Custom to your ride at that level. Read what I wrote to Mike and learn about these Hemis before you jump. Enjoy that Ram. They are tuff ass trucks done right.

Diablos testing showed that CAIs do not lean out the pickups. If they don't lean out the mixture on a Speed density motor, then in reality, they aren't flowing any more then stock. Cooler air, maybe, but more air, nope.

As far as the exhaust goes, I don't know anything about the Rams system. I know on the SRTs, the exhausts aren't restrictive. The stock mufflers aren't great, but the rest isn't bad. In fact, I'm going back to a stock exhaust on my 11sec Jeep SRT8 to cut the sound. Corsa's 3" duals flowed too much, hurt the bottom end torque, and hurt the times. The MagnaFlow system sucks balls and chokes down to 2.25" at the back mufflers, plus fit is awful, so thats not staying on, so rather then buying something else, stock will be fine with an aftermarket muffler.

A Ram system stock is very restrictive in 2004 or 2006 as mine was. A good CAI on a stock truck thats much less restrictive with an Exhaust system change thats way less restrictive also your telling me that the ECM wont correct F/A mix ( wont be lean) and it wont flow more cfm. Your not seeing lean on stock because the ECM will compensate on the level at which a stock motor is at with several bolt on parts. Thats why you pull fuse on ECM to have it reset to new F/A level based on Air Mass and O2 levels coming out of exhaust. What raises the dyno recorded gains on paper of HP and Torque if not more air and fuel in cylinder along with timing curve. It would have to be real cold air to get 25 to 30 HP from CAI and Cat back exhaust in all seasons. It takes fuel and air to make more HP and Torque. Dont care how you get it in there on a stock motor, blower, turbo, Nitrous, stroker kit. All those Items increase CFM or O2 level in cylinder which needs fuel to prevent lean condition. Fuel must increase to balance F/A mixture. If you cant increase flow or cfm you cant increase fuel without being rich. Explain to me how a Throttle Body, Headers, Heads and Cam, Long tube Headers put 108 rwhp to a stock SRT. Fuel and air increase from higher CFM. Why does Diablo have 91 Octain Tune, 91 Octain tune CAI. 93 octain tune and 93 Octain tune CAI.
Later, past my bed time. Convence me tomorrow I have wasted a lot of Money On exhaust systems and CAI systems and that Im not putting out more HP and Torque. Tell my tires that.

Okay, I have no idea what you just said. Sounds like you're quoting manufacturers numbers. Everybody knows manufacturer numbers are way exaggerated. Generally, take their numbers and cut them in half.

As far as correcting for added air, yes, the ECM will adjust, but it takes time. We don't have Mass Air sensors, so the motor doesn't know how much air is getting in until the O2 readings tell it if its running rich or lean.

Mike,
I have built a few of my own Chevy and Chrysler engines since my teens. 1 AMC 304 also. I do not know it all for sure. Or claim to. I do know that to increase HP and Torque it requires more fuel and air in combustion chamber. At the proper mix ratio, with proper burn. The old saying about"no replacement for cu in" thats based on the size of the combustion chamber and the amount of fuel and air it will suck in and burn. People who "Port Heads" is to increase air flow in to and out off combustion chamber. Allowing more fuel and air. Bigger Valves same effect. Or more valves ( Ford ). Higher and Longer Cam Valve Lift and Duration or time Valve is Open, let more air in. Less Restriction. Headers and high flow exhaust increase out bound flow, Better Intake Breather and Manifolds increase inbound flow. You can only do so much with Timing without engine damage. If your making big Power your burning more fuel at the correct ratio to air in combustion chamber. Everything coming into or leaving out of combustion Chamber effects its ability to make power by being restrictive to flow or not. I hope we can agree on these points.
I do not want to the Guy with the 2500 Ram to think Diablo Tuner is needed beyond its SAFE canned tunes for a truck with a CAI and Better flowing sounding Muffler. My current Ram I own is my 4th. Bought new. Several different Plymouth's and Dodges from 60's and 70's I can tell you beyond speculation A Good CAI with High Flow Filter and Less Restrictive Exhaust makes more HP and Torque. It does so without a Tuner. The Canned Tunes Provide a more aggressive Timing curve setting, Max RPM, and a few other adjustable things to really take advantage of the Improved Flow provided by the bolted on improvements. More Fuel also in some cases where needed within stock limits of fuel delivery. Custom tunes and Dynos aren't needed until Major changes are made. Aggressive Cam, Better Flowing Heads, Larger Bore Throttle Body, Stroker Kit. Bigger Fuel Injectors, Blower. Turbo, Etc. That is my point to our Hemi Ram 2500 friend on this Thread. Use the Canned tunes and Enjoy your truck. You don't need custom tunes, Yet.
Mike, there are many Dyno and Drag strip runs out there done by individuals, not Manufactures to prove what effect bolt on improvments have on HP and Torque. The ones that work, Improve Flow.
Happy New Year, to all.

the saying is "theres no replacement for displacement"

[Quick]

the saying is "theres no replacement for displacement"

Ummm, no. I think he's just sayin...

Got any dyno numbers?

And please explain about pulling the fuse on the ECM over night...
Are you saying that effects open loop operation? Can you elaborate on that?
For closed loop operation, just how long do you think it takes the adaptives to fully adjust for any physical mods? And what ECM adaptation is adapting to your driving style?
And sorry, that "throttle calibration" method is an urban legend. It takes a StarScan to do it. (I will say that my experience is with the LX hemi's.)
