I installed the Soler TB on my '19 M7 Stingray and started the car which idled at 1000 RPM then dropped to settle in at the required 600 after a brief period
I drove the "quick learning profile" of

1. 2 x three minute IDLE runs interspersed with 2 x one minute OFF intervals.
2. Took the car out on the freeway and then city streets to get the speed above 44 mph and slow in traffic. Put about 50 miles on the car with a dozen or so full stop/accelerate to >44 mph.

The throttle response was immediately improved with some minor stumbling/hesitation on acceleration between 1000-2000 RPM in first gear that reduced noticeably during the trip. Apparently "learnin' " was taking place. The stumbling has all but disappeared.
The TB made throttle response what it shoulda been out of the factory.
Kudos to Mike at Soler! Great product, excellent customer service.

 

I didn't do battery, no error codes, just drove it to teach it.. that was it

 

The Soler MTB is one of those things that suddenly appears every few hundred generations that redefines humanity and changes it for the better.

Ya, it's that good.

 

As noted for the LT1, one size! It's a modified OEM throttle body. Easy install, works great.

My Experience:
Had a 2014 Z51 Without MRC and drove mostly in Track for the other benefits, including faster Throttle Response. Got a 2017 Grand Sport that comes with MRC. Had to drive in Touring to get a ride like my Z51 none MRC! In Sport it was initially harsh hitting even small bumps. Was frustrated with the slower Touring Throttle Response (called slow Tip-In) especially when taking off.. To get what I had with my 2014 would have to drive in Track! That rattles your teeth even on the relatively good, pothole free roads in Eastern SC!

Bought a Vitesse throttle controller and set it mid way at 4/5 setting out of 9. That about matched what I had in my 2014. Got the GM MRC software upgrade and was able to drive in Sport with the features it provides including faster Throttle Response. No need for the Vitesse which only provides more throttle movement for a given throttle movement. Saw comments about the benefits of modified Throttle Bodies. The Soler tech info showed why it was different and better than just increasing throttle movement for a given pedal movement. (note they now sell BOTH but I just installed their modified throttle body and saw a significant improvement when "taking off" with my M7 and with a quick pedal movement when accelerating while moving!

Since my business involves gas flow transient movement, understood what they accomplished. Validated with info from other modified throttle body sellers info.

Made a PDF of my "Install and Why it Works" (which if you're technical may be of interest: http://netwelding.com/Soler_Mod_TB.pdf

GREAT PRODUCT!

 

Thanks for the input Jerry. Ordered the TB from Soler this morning. Did not opt for the throttle controller however. Should be ample improvement.

 

Once you've tasted the Soler candy, you'll be contacting the Candy Man at Soler very soon and ordering the Soler Throttle Controller.

Trust me.

Enjoy!

 

Well I added the Soler throttle body to the Stingray today. Install went well. I took out the cheap OEM air filter and replaced with a K & N drop in filter. I followed the learning instructions given and then drove the car for about an hour. Unfortunately I have to say I was extremely underwhelmed. I did not notice one bit of difference in throttle response. I have a base Stingray without performance exhaust and driver modes don't do anything for throttle progression. I sure hope the car simply has to "learn" more in order to notice a change in performance. If not, will be sending the $435 throttle body back to Mike soon...

 

got to add the tc ....they work well together and made a massive difference for me.

 

I noticed a difference with both of those mod’s individually. It will probably take a few ignition cycles and miles for the relearn to be completed.

My question is are you short shifting or lugging the car?

 

Not short shifting or lugging. Just drove several cycles at 44mph or above and accelerated and decelerated. I was revving up to 2500-3000 rpm before shifting. Towards the end of the drive started revving to 3500-4000 before shifting. The car ran fine and there were no codes or errors. However based on the overwhelming positive comments on the forum, I was extremely underwhelmed by the throttle progression. Again, my car is the base Stingray, non-Z51 and did not have any performance exhaust. I added the Corsa Sport axle back exhaust a couple months ago and an very happy with that. Changing driving modes on my car does nothing for throttle progression (except changing to Eco which makes it a 4 cylinder). During the drive, I even changed modes from to touring, sport track etc like the instructions stated knowing nothing would change in the throttle. Basically I
m extremely disappointed thus far and hope it just needs so more ignition cycles to kick in. Also, I shouldn't need to pay another $75 for a throttle controller to notice any throttle improvement,

 

i understand your perspective and get it, my point was the combo of the two components together are what people on here rave about.

i didn’t do one then the other so I can’t relate directly to what you are saying and experiencing but I can tell you the combo of the two of them for 475 was the best money I have spent on any mod ever hands down...and many here will say the exact same.

also, at the end of the day if you aren’t happy mike will give you your money back easy...so no matter what you will have a good outcome.

good luck buddy and please let us know how it works out and if you get improvement with a bit more learning time.

 

Yes I'm not giving up yet and plan on giving it more time. I will you let you know how things progress. Thanks for the input.

 

Think it's more than just driving for an hour. Takes starts and stops for the air/fuel MAP to adjust.

Also may depend on what you are expecting! I had a Vitesse throttle controller but only set it at 4 versus the 9 level where some say "what a big difference." Not sure of the Soler throttle controller range but this pic may help. It is from another throttle controller company BUT the C7 OEM "tip-in" appears similar. Note the OEM throttle response, like many cars only opens the throttle body ~15% for ~30% peal movement. That is a typical "slow tip-in." Makes it easier for the average driver in bumper to bumper traffic, for example, to control the car. With the throttle controller set at max you get ~80% throttle body opening at ~50% pedal movement. NOTE all are 100% Throttle Body at 100% pedal. You get zero extra power just the perception of more! I call those settings, "Boy Racer!"

After I removed the Vitesse Controller, once I was able to drive my Grand Sport in Sport Mode 95% of the time (where the throttle response is faster,) I still felt the small lag with the OEM tip-in. It was particularly noticeable when taking off from a stop. The Soler definitely reduced that slight "hesitation." I also can tell the difference with significant pedal movement when cruising but that is more subtle. If you want to feel the "Boy Racer" difference you'll need their controller!

SIDEBAR
The significant change some experience (and like) with max response setting on a throttle controller reminds me of my first car! As a teenage I modified a '41 Ford Coupe by replacing the flathead V8 with an 1/8 bored '50 Olds engine. The OHV Olds was much higher in the engine compartment. The car used a pivot level arrangement from the gas pedal to where the vertical rod from the pivot attached to the horizontal linkage to the flathead carbs. To clear the Olds engine, the vertical rod had to extend above the pivot point by about 5 or 6 inches. Cut the upper rod and had an extension section brazed between. That worked BUT with about a 1 1/2 inch gas pedal movement I went from idle to the 4 barrel fully open. The gas pedal was still over and inch from the floor at max throttle opening! Bit tricky to modulate but got used to it! BUT 60 years later not what I want now!

 

Did you do the battery disconnect? After i did mine,it took at least 100 miles of stop and go driving before I feel it relearned

Initially it took away my pops and cracks on deceleration, they are back, and I feel the exhaust sounds choppier to me (Intake, cam, long tube headers, and corsa extreme)

I have the throttle control I need to put in, maybe tomorrow, since my car is tuned they may have already tweaked the signal

Dont give up.yet sir..

 

I attempted the battery disconnect, but was hesitant to mess with it. In the end I did not disconnect and just did the quick learn process. I spoke to Mike and will give it some more time and driving cycles. I hope that's all it needs. Thanks for the response.

 

If you are expecting, OMG! feel all the new horsepower results, you will probably be disappointed, but the Soler TB does make considerable improvements in the off idle/ low end performance of the car. The drivability of the car improves remarkably after the relearn takes place. The stumbles that plague the M7 cars from takeoff in first gear go away and the car becomes far more responsive on the bottom end of the rev band. Throttle tip in on my A8 Z really improved also but I personally noticed it more on my M7 GS.

 

I read in one of the threads that you might be able to pull the ECM/TCM fuse instead of disconnecting the battery. I think that would be much easier. Maybe Mike can comment. I plan to install a Solar TB and TC in the spring when she comes out of storage so an answer would be very helpful.

 

I installed the Soler Throttle controller only last week. Like night and day. Very happy with it...

 

I have been dying to do this and have read all the threads from the last two years on this subject. So after reading this thread this is the very reason why I am hesitant to pull the trigger.

 

really? dying to do it?

Because 1 new corvette/ C7 owner outta hundreds or so expected more or something different than what mike and his product promised?

sorry ....weak excuse.
