SHADOW E-Drive ADVANCE 4 Throttle Controller

I found this in my searches, anyone have any clue about it?

+How it attaches?
+what it actually does?
+Will it void lease warranty?

I am quite interested in improving fuel economy

Cannot answer your question but here's my opinion...
I would not tamper with the Audi for warranty reasons. It's not great on fuel but not terrible. If fuel consumption is your main concern simply use a light pedal. I jump away from lights ...that eats up fuel badly. I would not stick that device in any of my cars. If I really wanted to change performance I'd have it professionally tuned...and assume the risk. Also by looking for economy does the engine lose power. It's sluggish enough as is.

Hello!

I got the 2017 Q3 on September 22 of this year. Progressiv trim level with S-Line package, 20 inch wheels and Utopia blue paint.

I am leasing this Audi and I was hoping to improve acceleration and fuel mileage.

I've already done some Carista customizations and I was looking into other plug and play options that wouldn't show up in any Audi diagnostics.

Thanks!

This is yet another product like SprintBooster described here pretty well and in satisfactory (non-worry warranty) use by several folks on this forum including me. I also use a similar but more variable (like e-Drive) product called a Pedalbox on my R8. I am fully satisfied with the installation and utility of the Sprintbooster on my Q3 though the R8 does in fact benefit more from the added variability of the Pedalbox.

These devices simply plug into the throttle connector of the car (hence no warranty issues as they are fully reversible and discreet to the CAN) and alter or modify acceleration signals between your foot - the physical pedal - and the car, in a different, modifiable way.

I will caution on two points though - First, they cannot and do NOT add power. This is simply not possible with a throttle-modifying device. What it DOES do is change the relationship between your pedal position and the corresponding signal to the car's electronic throttle. This is a ZERO SUM function though - that is, if you add more throttle sooner in the pedal travel you MUST therefore add less later, so if the slope of acceleration of the pedal input is higher (faster) in the beginning, it MUST be flatter (slower) later to reach the same point - look at the reference curves in the first post direct. Thus, NO additional power is ever created. BUT, the throttle sensitivity is GREATLY enhanced AND THIS gives you the driver a different experience, often yielding the FEELING of more power. btw, this is a usual technique of all automakers to adjust their car's drivability and is the first thing that "sport" buttons also do to some degree. These devices just capitalize and enhance that function. Many folks would say, just step down further on the loud pedal to get the same effect - true, that's rational but in practice IT is different. Your foot feedback relative to pedal travel is a psychological input and just using more travel to get more throttle is affected by the slope of the curve that these devices modify - hence a different input and feeling for/from it.

Second, I would NOT expect a change in fuel economy with these devices as their function actually encourages faster starts and usually LESS economy - which is why they aren't programmed this aggressively in the first place. BUT, I have NOT noticed a variance in MY own fuel use with the device - prolly cuz I spent most of my time with the foot to the floor anyway ;-)

So if increased throttle sensitivity to foot travel gives you the feeling of more acceleration aggression and 'power' is your primary intent, try it - you'll prolly love it as I do my Sprintbooster and Pedalbox, but if increased fuel economy is your primary driver, don't as you'll likely be disappointed and therefore unhappy with the choice...

Indeed - I should've been first to welcome you but got caught up in trying to help first, so welcome to the forum - show us some pics and enjoy...

Thanks everyone for the welcome.

On the note of faster acceleration response. Is there a huge disadvantage to turning off ESC or even just setting it to Offroad for general dry weather driving?

Tough balance but....If you had to choose between economy or power what would it be. I supercharged my Mustang. Got power at a price of 10mpg. Would definitely like more power in the Q but realized what I was getting at test drive and settled for it. I do live in sport mode.

Unless I was in the mood for generally riskier driving safety or at a track where I was TRYING to hustle an HCG vehicle around for pure performance, I'd LEAVE the ESC on all the time (as I do). Even in the dry, you may come upon a two wheels on - two wheels off circumstance or maneuver (say on a sandy shoulder or freshly sprinkled leaves not raked up for Fall just yet - both examples I have come across) that you didn't/wouldn't expect when you turned the ESC off - and it could be an elbows & a$$ situation later regretted IMHO. But yatta hey, it IS your car ...

Yeah I wont be doing hard corners without ESC until im sure of the car. However, off the line it seems a lot more peppier.

I wish! No just hard cornering on country roads and highway onramps.

Also in my opinion, city driving requires acceleration to get through traffic and away from situations.

Sounds like you would LOVE a SprintBooster - I do - much better than living in Sport Mode if you ask me ...

Sprint boosters definitely take the irritation of the throttle lag away. That or just get a full tune done and squeeze some power ;)

Just installed the SprintBooster version 3 this weekend. Very satisfied with what it does. I agree with Roger - Instant gratification. It seems like I just got a new V6 engine and more. Now I feel the power of my Q3.
I used part number T10238 to remove the gas pedal easily from the floor.
