Throttle Controller - GOOD or S***? - NO paid YOUTUBER information in this video! - Technical ONLY 

I bought one recently as I have a diesel with throttle lag. The difference is amazing. Yes, you are not actually getting more power, but instead simply more throttle, but I’m telling you from experience. If you have a turbo diesel, the improvement in drivability is amazing. The low end lag is gone completely. I just set mine on auto.

This is a good piece of information for those people wanting to learn more about throttle response. I would like to add some more info on the subject. When talking about electrical adjustments such as a throttle or volume control and speed of response it is referred to as gain. Gain is the rate of response. You can have positive gain and negative gain. Negative gain gives you more control over at system but may reduce the overall output. The throttle controller does not reduce the total output but as stated modifies the lower 50% of throttle travel. While this works well on all in engines it is particularly effective for petrol engines as 70% of air flow through the throttle body is achieved with only 30% of throttle opening. Any negative gain given in the first 30% of throttle movement will give more control over power in this area.

Best explanatory video !! Well done, I know what I am getting now.

Great insight mate. I purchased an EVC controller this morning and will be fitting it later. Glad I did some research first and came across your vid. No unrealistic expectations on what it will do and im excited to use mine. Cheers!!!

Great vid, not a glorified advert for the product. Enjoying your channel as you guys don't talk shit like a lot of them😎👍

I’ve had one and I loved it! It was a Roar Pedal, made my accord say screw CA Emission Controlling my car does what it wants all or none. Worth it.

I have a throttle controller installed in a 2010 3l diesel manual Holden Colorado, when driving in traffic I like to have a very responsive throttle so I set mine on setting 9 in race it works fine, when I'm out on the open road I just use Auto setting ,it's all about experimenting with the throttle controller and finding what best suits you.

Good honest review I agree as a mechanic as well

Finally someone that explains it well. They’re nothing more than a cleaver illusion of more power because you’re getting more throttle than you’re used to for a given input.

Thanks so much for your explanation

i kept hearing youtubers say it would get rid of throttle lag, i noticed no difference and realise what I'm noticing is my engine lag

I have just installed the IDRIVE throttle controller it definitely makes a difference on the pedal response I used to push the vehicle hard before the IDRIVE installation now it’s not the case so I would say it’s worth the money but if you want more engine power this is not for you doesn’t change much on the torque or kilowatts people need to understand the difference that’s why it’s called a throttle controller

Good vid man. Sorght ya hoodie strings out haha. Cheers

Great advice

I purchased one for my mitsubishi delica d5 2010 petrol as the throttle lag was killer. most times i have it set in auto control but sometime power 5 setting and it made heaps of a difference compared to when i didnt have it connected. the factory throttle lag is terrible lol

What about the safety aspects of aftermarket throttle controllers? Most of these aren't certified. No throttle in a rail crossing or failure to decrease throttle in a highway?

I have ordered one for my Infiniti Q50 3.5 GT Skyline hybrid 364 hp. I have been told it will reduce the lag and rev almost instantly. There is currently a bit of lag and won't rev up instantly which is annoying sometimes. They say the lag is to make accelerating more smooth and more controlable. it will be interesting to see how it goes.

Thanks for the video. Question though. I have a Patrol ZD30 Di. Most (if not all) of the throttle controllers I find only support the ZD30 CRDi model. Why is this? Is there a throttle controller that will work for a direct injection ZD30 engine? Thanks!

I have a 09 civic and it has a really annoying throttle lag is a throttle controller something that would really help get rid of thenlag I've got (I've found out it's not just me I've spoke to a fellow civic owner who has asked about his throttle lag also)

I find it helps dampen the throttle when off road

Are throttle controllers car specific? Thanks.

Nothing substitutes for a professional engine tune, Factories don't tune for engines to run at there best. Just ask yourself, If there tuning IN throttle lag.... what else have they tuned in, or should I say tuned OUT in performance ....

The amount of people I talked to that have bought one and think that it gives them more power well, it's pretty much everyone. I have a background in electronics computers and also EFI. I've given up trying to explain it, people just don't believe me.

If a throttle controller eliminates the delay, will the vehicle consume more fuel?

Would one of these work on my TB42e GQ patrol? *sarcasm*

Is a throttle controller good for towing a caravan, would they help when pulling away from a dead stop. Thanks Steve

Most of the reactions are positive reactions when you plant your foot. No the throttle controller does not give you more power but it does give you your power quicker

Great Vid. Ta. Gotta ask though... There must be something about the throttle controller that causes the ECU to react differently. If you stab the pedal to the floor there is quite a delay before the engine responds. On U9 the engine responds so quickly. It is almost as though there is more than just a TPS value being sent to the ECU by the pedal. That extra response is a bit addictive. :)

You appear to be talking about some sort of throttle ratio controller ? Which I have never heard of and frankly makes no sense Or Are you talking about a Throttle Response Controller ? Which only increases the response time or in other works reduces the lag time, from pedal to throttle body. It does NOT change the ratio of pedal to throttle body. 0=0, 25%=25%, 50%=50% and so forth. If you are “trying” to talk about the latter. Then I suggest you check your facts.

People use them at about 25% and see a power increase relative to how much they are accelerating, they assume this will continue at 100% throttle. Very useful bit of kit but companies indirectly mislead people saying 'unleash the power'. Honestly not worth the effort of explaining and treading on eggshells to avoid lawsuits.
