it's just a toggle switch with some resistors and nothing more. been proven many times. woo hoo for mental horsepower.

 

Yeah after a quick google search the only info I could find on this thing (besides adverts for it) was forum reviews. The two positions of the toggle switch are just two resistance circuits. All this does is basically REMOVE one of the IMPORTANT corrections your ECU makes to determine the CORRECT timing and fuel delivery.

Basically, no matter what you think it did, it made your car run worse.

Sorry guys, I think you got taken....

 

from what I understood from the website's information was it makes the AIR/FUEL ratio be more closer to 13.0 (the 'safe zone' A/F ratio is between 13-15; don't quote me on that I just remember 13 as the low end for sure). And they say that if its closer to the lower end then you should theoretically gain some extra power. The unit does attach to the Air Intake Temperature sensor, and there was an explanation for that on the website too.


The switches have I,II,II for tri-phase. I think it is different modes (similar to Blitz Throttle controller). I am assuming in mode III, you will be real close to the 13.0 AF ratio, and when you are in mode I, you are a little further away from 13 but still lower than the AF ratio with stock settings.


As for 17hp gain.. I think the gain depends on the car. I'm pretty sure when they mentioned 17hp gain, they did it with a high end car. So if someone did dyno for the Fit we could put it in better perspective.

You are right it it doesn't directly have anything to do with AT shifts, but apparently the way the unit modifies the signals produced, it changes the CPU gear shift timing.

 

Well the car already runs in the mid to low 13 AFRs at full throttle, just like any N/A production car in the world. Plus, getting anything close to an accurate AFR requires WAY more than random inputs to the IAT sensor.

If you tell the computer that your intake temp is 25F, and it's actually 50F, and somehow you get the right AFR, what happens when it's 75F? You run rich. Way rich. What happens when it's -10F? You run way lean.

 

lol if this is true, then this must be the mechanism I didn't quite explain/understand

 

Also, when you are at less than full throttle, your car is in closed loop. The fit ECU is extremely good at correcting fuel values. No matter what I do to my E-manage, it will always correct to 14.7 within a few seconds. I can only change anything in full throttle or in boost. Nothing more.*

*Until I get the F-manage, which allows you to trick your ECU into auto-correcting for whatever AFR you want!

 

yeah i don't ever think i'd waste my money on something like this

 

this is so freaking lame...I can't believe people fall for it....

 

If you are in Texas, and get smoked by an old man in a silver Fit Sport, you will understand. There are now two people here that have installed one of these things, and can confirm that their cars have more power in the low to mid range, and all of the naysayers are people that have not purchased or installed one. It reminds me of people that say they hate Chinese food that have never eaten at a Chinese restaurant. You are obviously basing your opinions on here say, and not personal experience, and causing yourself, and others from benefiting from a positive improvement in performance, and driving pleasure.

 

chinese food is a preference. Even if you don't like it, you can't deny that it's food and will make you full as such. What I'm saying is this product has all the signs of a scam. The website never explains the workings of the device, and the only "proof" of its effects are hand drawn "dyno" sheets collected from kindergarden class.

The placebo effect is strong with this one.. Also, if you think you're gonna "smoke" me with a resistor accross your IAT sensor, then you should check my sig again. If you still believe it, I've got a bridge to sell you LOL!

 

it is a few resistors in a box. tricks the engine into running at cold air/cold startup parameters 100% of the time, the power difference you feel is similar to when you JUST start your car and hit it (compared to warmed up for a while). eventually the computer will learn the 'broken' IAT and you'll just be running rich all the time.

i fell for it in the late 90's. this isn't me being a jerk or saying you don't 'feel' any power or change, this is personal experience, and i admit i got scammed. you probably do feel a diference... but the car's computer will adapt for the faulty intake temp and you will eventually lose power and may even foul your plugs sooner than usual.

it sucks to think that you spent a lot of money on something that has been proven to be a scam; i suggest just trying to get your money back.

oh and those dyno charts are absolutely hilarious. some of the differences on the lines are like 30hp.

 

I am reminded that...

A man convinced against his will is of the same opinion still.

It doesn't affect us, Texas Coyote.

here ya go:

IAT Timing Tricker

99 cents at radio shack.

if anyone wants to try it, it will increase the fuel side of the air/fuel ratio, and might help if you run a lot of NA mods like intake and manifold. down side is, it will eventually do nothing as your computer compensates, and the extra fuel will make your plugs, sensors and cat go bad sooner.

 

I am happy for you that you can boast of having "the most modified Fit in Michigan" but bragging rights aren't important to me. How much did you have to pay for in dollars for each horse power and your right to boast? My car is a econobox that is considerably faster than it was in the bone stock mode, and I have spent a little over $500 on it. Why don't you let me sell you a bridge?

 

Yup these things are bad for your car in the long run.

 

17000+ miles, plugs look good, and still runs as strong as when I first installed it 26 months ago. If things change and I have problems, I'll let you know.

 

It makes your car run very rich. You're telling me that is not a problem?

 

Yep, those things are!

 

It is a lean burn engine, it makes the engine run richer than stock, not very rich at all really.

 

i'm just here to get in on the rofling because there's been a lot of it, and this is very rofl worthy.
