What is a "VTC?"

Function is actually in the name ' "THROTTLE CONTROLLER"

Freddy G · 10-17-2016, 01:31 PM

It's fun and all, but heard lots issues about it.

Yeah, I get that. My question is what are the advantages of an aftermarket TC? How much are they?

It's an aftermarket part that increases the sensitivity of your gas pedal so that, for example, it registers %100 throttle when your gas pedal is pressed %50 of the way, instead of the stock %50 throttle for %50 gas pedal pressure. This increase is adjustable via a small screen with + - buttons.

They are $180 new, and buying it used from a forum user comes with all of the same parts and functionality, so there is no benefit to buying new except for liability (I bought mine new).

It installs and uninstalls relatively easily, attaching directly to the plugs that electronically register your gas pedal activation. There is no direct alternative. There are parts that you can install into your engine to increase throttle response, which is what the VTC aims to emulate.

A throttle body will accomplish this more effectively than a VTC, and could render a VTC near useless, which would lead someone to sell it.

However, there have been a few documented issues with the VTC which could also lead to someone wanting to sell it. The programming of the VTC may periodically be incompatible with that of your car which would lead to emergency reduced engine power. This is a relatively small issue, and is correctable by resetting the VTC or resetting your cars computer at a dealership.

In my experience, the VTC's power output was incompatible with my cars throttle sensor and burnt out the circuits. I had to get my throttle sensor replaced, which my dealership thankfully did under warranty. Aftermarket modifications like the VTC can void your warranty for every step of the vehicle's operation that the part influences.

I recommend only getting the VTC under the following conditions:
1. You want your car to feel more responsive without modifying the engine.
2. You are willing to take on the responsibility of possibly voiding the warranty on your throttle and it's related parts.

Why are you not posting this in the classified section?!?

I'm now at the end of year/season #2 and have had no issues with it yet. I am tuned as well and have an intake but that's it. I'm mainly concerned about how much wear i'm putting on the clutch because you tend to spool up the rpm's much quicker due to the sensitivity increase and if you're not really good at a light press of the throttle, you're slipping the clutch way more than at stock.

But it's so damn fun, I can't turn it off.

The VTC allows you to adjust how quickly your throttle body's blade will open and shut. Also removes the factory emissions delay that is found in most vehicles today, so when you press the throttle, there is no longer any hesitation assuming you are in SP mode. Another option available is ECO mode which slows down the opening and closing of the throttle body, which reduces emissions and improves gas mileage if you decide to use it. There are many theories as to why some have experienced limp mode while using this device, but nothing solid yet. I would advise that you research this very well and decide for yourself. I have had mine for a year and 8 months with no issues at all. Make sure to press the gas pedal all the way when calibrating if you decide to buy one.

This below cant be true is it? - If thats the case, why wouldnt someone just put the pedal to the metal if they want 100% throttle???

Just to clear up a few things. The factory drive by wire system (electronic throttle) has a built in lag, or delay if you will. There are charts out there that show this. This delay is built in for safety and fuel economy reasons. When pulling off from a stop light, for example, when you press the pedal 15%, your actually getting about 7% throttle, to get to 15%, you need to press the pedal to about 25%. It is progressive, the deeper you go with the pedal, the less the differential until you get to WOT.

The throttle controller assists in making the pedal to acceleration ratio more linear, like the old cable operated throttle bodies. Some throttle controllers, like the Viteese have a function to reduce response even further for bad weather or to increase economy as well, though I haven't tried that one. There are several different controllers on the market, all with different levels of adjustability. The throttle controller has been out there for as long as drive by wire.

The throttle controller is a voltage multiplier of sorts. Your pedal has a sensor that sends a signal to the throttle body motor. The controller increases that signal voltage prompting the throttle body to respond faster and open more. From there the TPS sensors in the throttle body send the signal to the ecm to send more fuel etc. Bottom line, it increases response in partial throttle situations, like starting from a light, accelerating on an entrance ramp, or passing slower moving traffic.

What it will not do is make your car faster. It is not a power adder in any way, shape or form. It simply increases the sensitivity of the pedal and provides a more linear feel. Yes, you can just press the pedal further. However, I have noticed two things about this, first, the actual response is still slow, and second, there is a point, combined with the delay that the acceleration is almost like an on/off switch. When entering the freeway for example, I press the pedal, the lag kicks in, I press some more, and then the car just takes off, to a point of almost too much acceleration. The TC makes the response more even and predictable in this situation.

The TC can cause occasional drivability issues. The factory drive by wire system has a built in safety feature, that when the ecu sees a difference in pedal position to throttle position, it sets a P2128 code and puts the car in reduced power mode. This is how the car saves you from the runaway Toyota syndrome. Some worry that a throttle controller may actually cause a runaway throttle situation. The controllers have their own safety feature, that when it senses a malfunction, it essentially shuts off, and the factory program takes over. I have yet to see or read where a TC has caused a runaway vehicle. What actually causes TC's to do this from time to time is beyond my knowledge, but when it happened to me over a year ago, I recalibrated it and it's been fine since.

Can this factory delay be tuned or built out. Some say yes, and some say no. Some tuners have said that the throttle parameters are locked and trying to change them results in the reduced power mode. Some say it can be tuned out. Some have built engines to the point that the TC causes more severe traction issues, I can see that happening.

But if you don't want to tune, or modify your engine, or don't tend to go flying around town at WOT, I have found the throttle controller to be a great tool for better throttle response and control. So unless this controller has a functionality problem, it is a good buy.
