These are designed to optimize the critical throttle (voltage) signal that determines the fuel delivery and spark timing. Flat and even dead spots in the throttle position sensor are automatically corrected using this unit. Direct weather proof plug-in connections. Installs in minutes.

anybody ever try it ? considering it for 351w make over

 

Looks like snake oil...

 

Your throttle position sensor is just a variable resistor, like a stereo volume ****. Push the throttle more, the resistance changes.

Ford uses a "linear" variable resistor, so half throttle gives half resistance as compared to full throttle.

What gizmos like that do is change the scale of the resistor, so at half throttle the computer thinks you've pushed the pedal to say, 2/3 throttle.

The theory is the computer will then apply the necessary fuel for 2/3 throttle even though it's at half throttle, and you might accelerate harder. I say "theory" because in practice it doesn't work well because the computer is smart enough to compensate for failing throttle position sensors and will re-adjust at least part way to rescale how it reads the sensor. This is to preserve emissions compliance, allow you to drive with a failing but not dead sensor, and maintain some kind of reasonable gas mileage.

Overfueling a gasoline engine results in more unburnt fuel leaving the engine which then gets burned in the catalytic converter producting tremendous heat and wearing it out faster.

Burning gasoline anywhere but in the engine wastes gasoline which in turn wastes money - YOUR money.

Considering the mileage most trucks get, that would be a LOT of money

If you want to increase power, you actually increase air and fuel, and not just lie to the computer that you did because it monitors what comes out of the engine so it knows....

 

thank you sir , at first glance it seemed to do alot

 

Also depends on the aplication although the theory will always be the same... it's design is to fool the computer. In true drive by wire aplications where the computer intreprets your foots position and applys throtle in relation, this device will remove the preprogramed lag and give you a better response. A/F ratio is not affected in this case so there is no fear of added emisions or added wear on the components. I dont believe any of the ford trucks use this technology but I can say with my merc, it really cleaned up the spongy throtle lag.

 

None of these do good things.

 

To each is own.. I guess a definition of "good" would help here. I merly offered an application where there is no ill effects or chance of damage. To me I dont see that as bad thing.

 

This changes the input into the computer. It does not change the position of the throttle body because that is a mechanical input. You're creating a condition where what the computer thinks and the actual throttle position are two different things. You're tricking the computer into thinking that the throttle is more open than it is. This will put in more gas with the same amount of air. Your gas mileage will drop and driveability will suffer. At partial throttle, it might feel a little more peppy, but it's all in your head.

In your situation, with fly by wire, all these do is make the computer open the throttle body more quickly, so it feels like you got a big increase, but in reality, it would be cheaper to just give it more gas.

 

Let me explain more simply. I was refering to DBW applications only. You can MASH the throtle all you want but you are mearly a voting member in the process. With adaptive throtle the computer has the final word so without manipulating the signal, the throtle actuation is preprogramed and fixed. There is no correlation between the A/F ratio and throtle position in this application. A/F ratio is monitored by computer and adjusted via imput from the MAF and O2 sensor. Again I doubt ford is using this technology but offering an application where this device is usefull without taxing the emission systems.

 

I feel that its the same as all the other junk like hot air intakes, throttle body spacers, tornado, snake oil spark plugs etc.

 

Ummmmm are we talking bout the same thing? A "signal enhancer" is not designed to add power. The examples you have stated claim to, but I agree, do not deliver.

 

see its tricky , on one hand i understand it doesnt have the power to add power but when it said it get rid of that MASH DELAY thats what i want but if it a sacrifice of fuel economy im down, i mean its a 6000lb vehicle what power adder isnt gonna kill sum gas my truck is 4wheel drive , and it always has sumthing in the bed or being towed so question being would it be alright for towing and hauling ? sounds like it could help me out on postponing my differential swap trying to find a ford 9" is a in south jersey

 

Probably be better off with a new TPS, cheaper too, rather then add one of them to mask problems a old one might have.

 

You don't have any sort of "mash delay." You have a mechanical linkage to the throttle body. It's not going to open the throttle up any faster with that little black box in there. If you want, you can mail a check to me* for that amount and I will post a youtube video of me burning it. This way, you get to pretend like you spent the money and got some sort of satisfaction out of it without actually losing anything.


*Do not actually send me a check.

 

damn that was really to the point , is it really that bad ? i mean heard of people using dryer vent tubing as snorkel intake , and heard of people puting acetone in the gas tank , but i never heard of a throttle voltage enhancer , you know i didnt even think about but when i went back to the site they had on the market for quite a bit but i couldnt find any reviews for it , now thats sum
