Are there any of you who've installed a Soler throttle controller without installing a Soler throttle body?

The reason I ask is because I have neither (yet), and was considering getting the TC first. If you don't mind, what sort of driveability/performance results did you notice with the TC installed?

TIA,
Larry

 

I have both products but have only installed the TC at this point. It does make a difference in throttle response just by itself. Plus it is simple to install.

 

Really wakes up the car. Much better throttle response.

 

I know, you asked about the TC only. I have both on my 2019 A8 GS but I intentionally installed them separately so that I could evaluate the performance differences of each component.

I installed the throttle body first knowing that others had successfully eliminated the off-idle hesitation known to exist on some A8 models. It did exactly what it was supposed to do. No hesitation on initial tip-in and clean low end acceleration. Can't say that I've noticed any other improvements as a result of installing the TB but eliminating the slight hesitation was the objective and that was achieved.

The installation of the TC makes all the difference in terms of linear throttle input vs throttle response. The difference, if you choose to use the TB or not, is immediately noticeable and, depending on the mode selected, can be truly astounding. While it doesn't add any actual performance it's a simple add-on that really wakes up the car and improves the driving fun factor immensely.

The TB and the TC do different things and the benefits of each are quite noticeable on their own. However, the overall improvements of a combined installation are certainly worthwhile in my experience.

 

Head over to my garage I'll install it while you wait

 

Thanks, guys. Your answers are what I was looking for.

 

They don't have to be installed separately, unless you want to evaluate TC functionality with the stock TB.

When configured in Original Equipment (OE) mode, the TC functions as nothing more than a pass-thru for stock throttle signals to whatever TB is installed.

 

Hi everyone, just do it you won’t regret it , difference is most awesome, I’m sorry I didn’t do it right away, you haven’t lived until you try the ludicrous setting, cu on the road, zonlyway

 

I have a Soler TC installed. I also have a ported TB. I installed the TC first, about two weeks in advance of the TB. The increased response (have not tried LUDICROUS mode) in Sport settings was immediately noticeable. When combined with a ported throttle body, the acceleration is highly improved over OE setting. The Soler TC can be set at OE response, but why do that, right?

OP, you might can save a few dollars and buy used. I did for both the TC & TB and worth it.

 

I also run both. Sport 5, which I believe most closely approximates linear throttle response, is my happy place.

Why run OE mode? For the circumstance cited above - you've installed both but want to evaluate performance of the TB alone. I also found OE mode useful for the car's initial "learning" of the new TB. I preferred this occur without TC input/assistance.

 

Both made a huge difference on my M7. The off idle stumble is gone. I also bumped the idle to 850 from 600 rpm and it helps the roll out from a stop.

 

Thanks for the offer, but Northern Illinois is a bit of a drive. Besides, it's not like I can't install it, just haven't got around to doing it yet. Install is just four bolts and an electrical connection (besides taking the air bellows loose), then doing the learning routine. It is on my list of things to do before the car goes into hibernation this winter. Perhaps some day I'll get up to your area again, with the car, and we can talk shop.

 

I installed the TB first followed by the TC a month or so later.
The TB improves the baseline throttle response to remove the mushy low end response and make it much more predictable, and provides wider opening throughout a large range of throttle openings.
The TC allows the driver to adjust the response of the butterfly valve in a number of selectable modes, starting with slow opening with throttle application, going to extremely fast response in the Ludicrous mode. Basically the TC can give the OEM response or several dozen other throttle opening options from snail speed to lightning fast in Ludicrous mode. (I usually set mine at Comfort 7 or Sport 6.)
Suggest trying the Ludicrous mode for the first time in an open area with no traffic. Also, carry a spare set of underwear in case you color code the pair you're wearing.

Just ordered one yesterday for my C6, I've always been a part of the "throttle controllers are snake oil" camp but it seems like Soler really has something different so... I'm gonna give it an honest try and see if it changes my mind. I'm hopeful it will.

 

My thoughts are you will be very pleased with how the TC works.

 

I have only the TB on both our C7's, huge improvement off idle on a M7 car and added one to my A8 after it hesitated from a stop a few times with traffic coming. Sadly the M7 was totaled a few weeks back by a inattentive driver so that one I have for sale in the C7 parts page.
Here is the difference between stock and ported.

I started out in lower settings but now I run LU 9 all the time, seems just right.

 

You must like living on the edge.

 

So is it really that noticeable a difference between the modes? I have a 2020 explorer ST that has built in pedal mapping with the modes and its a pretty aggressive transition between them. Curious if thats what I should expect or something more subdue. Should be here tomorrow, Pumped to try it!

 

Depending on what modes you select and the setting within each mode the difference can be subtle or pronounced. Your choice.
