2019 GS, A8. My previous Vette was a 2013 C6, M6. Manual shifting was great fun, and I do miss it, but I also missed the simplicity of an automatic in traffic. So, A8 with the triple flush and a Range. So far, so good.
I had read just about every post about throttle bodies and throttle controllers and decided to give Soler Engineering a try. FYI, I messaged Mike and inquired about a CF discount, and received one, so give it a try. I purchased the LT1 TB and added the TC for an extra $75.
First up was the TB installation:
I won't post pics of the TB installation, because it is so easy to follow the well documented instructions that anyone can do it. Plenty of pics to help you understand but it's 4 bolts, a sensor, and 2 screw clamps. It took all of 10 minutes.
I didn't want to disconnect the battery, and didn't want to go to a dealership, so I opted for option B, the Abbreviated relearn procedure. It's very well documented, and quite simple.
First thing that I noticed upon start up was an initial rough idle that only lasted a few seconds. Then it smoothed right out. RPMs for the A8 stayed right at 650, M7 should be slightly lower at 600.
Followed the rest of the procedure, then took it out for a test drive. Off idle low speed response was much improved, I was pretty happy. No stumble exhibited.
On to the TC installation:
Again well documented and pretty simple. At first I mounted the display too low, and couldn't see it while driving. I rerouted the cable and attached the display just to the right of the HUD buttons. Mounted too low. Couldn't see display while driving. Remounted display. I fished the cable thru a small opening left of the steering column. Completed installation.
The TC really compliments the performance of the TB. The off idle response now is incredible, much, much smoother. Acceleration now seems quicker, lots more fun.
Hope the pics help, I didn't find many on the Forum when I went to install mine.
Not at all Mike. I just connected it though the hole in the carpet that already exists at the base of the pedal, behind the pedal. It’s completely hidden and does not come in contact or interfere with the travel of the pedal. Very clean! Also I did not stick the controller to the carpet so I can turn and look at it to change the setting. Great device Mike, Thanks!

Very clean, indeed. We have been asked by customers to extend the controller-connector harness for this purpose, but doing it the way you have, that may not be necessary. Thanks for posting.
Mike, I wanted to conceal my controller as well, but didn't think that I'd have enough harness length to get it behind the carpet. I may try again now that I see that it can be done, but a longer harness wouldn't hurt.
Mike, I currently have the Tony Mamo TB and its fantastic ! Just curious how your TC unit would work with this TB or has anyone else used your're Tc with a TB other than yours? Thanks Scott.

Hi, Scott. Yes, it works with any TB. That is, it will sweep along whichever TB characteristic curve you have, OEM or aftermarket.
It is designed so it is quasi-linear at the center of its range when used with our TB's, but I bet you can find a spot you'll prefer rather than stock even if not used with our TB's.

Mike talked me into taking my Mamo TB off and trying his. I sold my Mamo. It's worth it. I got the TC as well and mounted mine behind the carpet. I ran the cable up the console and mounted the controller inside the compartment in the center console beside the usb ports. Works great there.

I've never felt an issue with throttle response but can be swayed. What improved ?

Bruno, Mike told me to try his throttle body and if I didn't like it to send it back. I really didn't have anything to lose so I gave it a shot. I liked it better so I sold the Mamo. I'm fairly sure he'd do the same for you. I added the throttle controller a couple of days later and love the combo. The car is much more responsive. In tour mode I keep it at 2.5 in track mode I still haven't decide exactly where it needs to be. Right now I'm running with it at 1.3.
Tucked the harness back behind the carpet. The carpet is already factory split to accomodate the factory pedal connector. Tight fit. I checked and double checked to ensure that the Soler harness was not pinched. Well hidden and looks factory. Still prefer this location for the display.
Just placed an order for the TC. I have the TB already and it made a huge change to the off idle stumble. I've been driving manual transmission cars for many years and I still stall my Z06 more than any other car I've owned. I'm not sure why I can't figure it out, but it sure is embarrassing! Maybe the TC will help.
I installed a Throttle Control a few weeks ago in my 19 GS M7. Sure could of used it when I had my 14 Stingray M7. The delay when in Touring mode was very frustrating. If Touring was like the Track throttle setting it would be bearable. But with the new TC I can adjust for rain or dry and enjoy what seems like a lot more power.
I ran the wires under the carpet using the existing hole, then ran the control in the center console by drilling a hole large enough for the connector.
Solar has a great product here and I would highly recommend the TC.
I know it needs to be vacuumed out : )

Bruno, everything, it feels like a different car, specially if you do both mods. There is a lot of technical info here at CF and on our website, but the way I like to describe it, in short, is that the car now drives the same way its styling suggests. A true drivers car; nimble, responsive, and confidence inspiring. Feel free to call if you have any questions.
You can't go wrong, try them. We are confident about swaying your opinion. If you do not think this it is worth it, we'll send you a return label and give a full refund. No questions, no grief, as simple as that.

Thanks,
Careful Bruno. That's how he sold me and I already had a Mamo throttle body. Seriously though the 2 together are well worth the money. I sold my other tb to defray part of the cost.
