damn bro, do you work for these guys?

 

sorry to say but maybe your butt dyno's alittle off [8D]

 

haha ^

in the morning when its cold out your truck burns extra fuel to get it warmed up.. because its reading cold air coming from the outside.. when it warms up it burns less and less fuel.. but if its saying the air is still cold then it'll keep burning more fuel.. how you get better gas mileage i wouldnt know.. but yeah i would like to have the power all around that i get in the morning

It might be but love my truck.

 

These items have sprung up like weeds in any automotive parts search: Speed Mod Chips. They claim to boost HP by 10-20 and not void any warranty.

WRONG

These aren't "chips" at all, only a resistor. Many of these "chips" are plugged into the IAT, or Intake Air Temperature Sensor connector. The IAT is a Thermistor that changes a reference voltage to the engine's computer. This voltage is translated onto a "temperature" and the computer will increase or decrease fuel delivery according to this temperature. Cold air is more dense and requires more fuel, hot air requires the opposite.

This "chip" fools the computer into thinking the intake air is colder than it really is and consequently feeds more fuel into the combustion chamber. While many sellers state that the chip keeps fuel delivery within a certain "curve", this information means nothing. The modification essentially forces the engine to run rich all the time. The idea is more fuel equals more power. Unfortunately, rich running conditions will actually rob the engine of power, as the air/fuel ratio is far from ideal and will make combustion more difficult.

Today's computer controlled engines rely on a battery of sensors to help it run properly. If one sensor does not operate properly, the "runability" of the engine is adversely affected. In the case of a constant rich condition, the oxygen sensors will recognize that there is unburned fuel in the exhaust (due to poor combustion from the bad air/fuel ratio). They will command the engine to run lean in an attempt to correct the condition. (if the mod chip doesn't cause the engine to run OVERLY rich, the computer can negate all effects of the "chip" by LEANING the fuel ratio, making the mod useless!). If the rich condition cannot be corrected by leaning the ratio, guess what? You get a big, fat CHECK ENGINE light! (They claim the mod won't trigger that, either!) And if your vehicle is under warranty and the dealership finds that stupid little resistor where your IAT should be connected, you can KISS YOUR WARRANTY GOOD-BYE!

If your vehicle is out of warranty and you ignore the light, more severe damage can occur. The catalytic converter cannot cope with excessive amounts of unburned fuel and after a while of running rich and dumping raw fuel into the catalyst, the converter will be permanently damaged. Raw fuel and poor combustion will also foul the plugs and foul plugs have high resistance. High resistance can damage the ignition system! Lastly, raw fuel can wash down and glaze the cylinders, and it can wash out the oil ring on the piston which will negatively affect piston lubrication and will cost compression.

The bottom line is this: The "mod chips" DO NOT boost horsepower - the graphs they show are fake. They DO set the Check Engine Light. They DO void the manufacturer's warranty. And they CAN cause severe engine damage. Anybody considering this cheap performance enhancing option should think again and invest in a real, professionally programmed performance enhancing chip that REALLY adjusts fuel and timing curves. These pro chips cost more money for a reason: they work. These cheap eBay "mod chips" DO NOT.

 

maybe with a tb and a msd kit it'll help.

why did you have a mechanic do it? its just a plug. how much did he charge you?

 

timwag2001- Nice post and good read. Regarding the mechanic question, I knew where the IAT sensor was located but the wires that ran to it were embedded in a protective plastic casing or conduit and I couldn't see where the other end connected. I'm definitely not mechanically inclined and didn't want to mess with the wires, so I had my mechanic install for me. He was familiar with this type of mod and installed it for free. He said it was simple procedure and it didn't take long at all. I know him pretty well and he takes care of my Ram and Sequoia. He has installed all of my mods except for the Superchips. I'm not too familiar with the MSD Kit, but I've been doing some searching on the forum about it. Will the MSD help with performance? Thanks

 

Maybe I can help clear this up a little bit. The power wire does not make the computer think the engine is 20 degrees cooler. The power wire is similar but not the same thing as the resistor mod. The resistor mod shows the same temp all the time where the power wire reduces the intake air temp the cmputer see's by 20 degrees. Our obd2 engines uses all of the sensor readings to help determine the timing. If the pcm thinks the air intake temp is 20 degrees cooler the timing will be slightly more advanced. This is probubly the main reason for the increase in performance not necesarily the increase in fuel.

This is how I understand it. If I am wrong somebody please correct me.

 

i think that the msd 6a box will make the plug spark 3 times instead of once causing it to burn the fuel more efficiently. getting a msd coil gives it more voltage (better spark). i think the blaster 2 coil gives you something like 45,000 volts. and some 8.5 wires will carry the voltage better. i think all together it will help you out a lot, especially with what youve done
