After running the Soler throttle body for a couple of months I picked up the throttle controller and installed it a couple of weeks ago.
The TB solved the mushy, indistinct low end throttle which generated repeated and embarrassing stalling of my M7. The TC added as much flexibility in throttle response as I could want with its nine settings in each of four modes (economy, comfort, performance and ludicrous) along with the ability to set an OEM mode. IMO Mike should market the TC as a "G-force multiplier" as that is the sensation I get in the advanced (CF, SP, LU) modes. The ECO mode feels like it's a VW bug running on three cylinders and the OEM mode is, well, OEM.
I had a few glitches in the process and Mike performed his usual stellar customer service to git 'er fixed and on the road.
Excellent hardware backed up by first class customer service.. as good as it gets!

 

I’ve been considering those two mods to my car. Could you comment further on what glitches you encountered and how they were solved?

 

I'm a future customer. I'd also like to know any issues or tips for installation.

 

The TB has worked as advertised from day one.
The TC worked fine but after a week or so it started dropping out, putting the car into limp mode (which was educational in its own right).
After following Mike's troubleshooting information the problem remained. I removed the TC to return the car to OEM configuration and Mike sent me a new unit and a return postage label for the bad unit. I installed the replacement unit and returned to throttle response nirvana.
During the TC misbehavior my OBD code reader showed a P2138 code - Throttle/Pedal Pos Sensor Voltage Correlation DTC which cleared after the new TC was installed
Mike indicated that the original unit's output voltage was a bit unstable when it should be a "constant value for any given pedal position, and it was a bit wavy." Am no electronic expert, but sounds like a bad chip or component.

 

Mike sends installation, calibration and operation instructions with both the TB and TC. Probably way more info than you need, but....
If you have the required tools on hand, figure
For the TB, no more than 45 minutes from entering the garage to lights out and door closed.. For the TC, skinny, flexible owners can do the complete install in under a half hour... For the rest of us, figure 1 to 1.5 hours. Add time as necessary for cursing and sipping a brewski for attitude adjustment.
On my '19 Stingray for the TB I used

• 10 mm socket for the four bolts securing the TB
• 8 mm socket or large flat blade screwdriver for the clamp holding the air duct on to the TB intake.
• Short wobbly extension to make removing the lower bolts easier. The driver side lower bolt is behind the control module and requires tactile locating. The passenger side lower bolt is more accessible but the wobbly extension makes accessing it easier.

For installing the deceptively simple TC, being blessed with diminutive size and flexibility are a plus as you will be working on the throttle pedal in tight spaces. Practicing your favorite %^*&^&@!#* curses ahead of time will save a few seconds here and there...

• A 10 mm socket with the wobbly extension makes removing the throttle unit hold down screw easy. It is a REALLY long screw, which makes it easier to reinstall, and took many more turns to remove than I expected
• When I disconnected the throttle connector, after sliding the red locking guard clear, after struggling to pull the connector apart I discovered the locking tab on my throttle unit connector was stuck in the engaged position and needed to be lifted clear with an awl
• Reinstall throttle unit, route the wire and locate the display as desired
  • I put industrial strength velcro on the back of the electronic unit and stuck it to the carpet behind and above the throttle pedal and ran the wire behind the carpet to the display unit velcroed immediately to the left of the A/C temp ****.

 

Great info. I just heard about these the other day in the "sucking air" thread.

I'm probably a future customer too, but there's a couple other more pressing things I want to do to my 2016 first.

Thanks for the write up!

 

I have the controller and it is a great modification 😎

 

Jim, thanks for the link for the Harbor Freight Wobbly Extension. I was hoping they would have a set.

 

Does the TB void our warranty? Is it CARB certified?

 

There has been a lot of back and forth on CF about aftermarket items affecting the warranty, and regarding the Soler TB IMO there are two paths.
1) Unless the TB was a proximate cause for a warranty claim, GM has no legal recourse to deny a claim.* That doesn't mean they couldn't give you the runaround in the process, but that's the law.
2) Swapping with the original TB is a 15-20 minute job if an owner is concerned about it when getting warranty work done.

Mike indicated that the Soler data showed the unit was at least as efficient as OEM and I suggested that he consider CARB certification, but have no knowledge if he's moved on it. I can only imagine the bureaucratic horror that would be... Commiefornia's CARB is a nightmare on a good day.
My '19 has five more years before I need to do a smog check, so will address it at that time if necessary. I may do a test but no certification to get more information.
Perhaps Mike will chime in with more information
Cheers!

Will using 'aftermarket' or recycled parts void my warranty?

No. An 'aftermarket' part is a part made by a company other than the vehicle manufacturer or the original equipment manufacturer. A 'recycled' part is a part that was made for and installed in a new vehicle by the manufacturer or the original equipment manufacturer, and later removed from the vehicle and made available for resale or reuse. Simply using an aftermarket or recycled part does not void your warranty. The Magnuson-Moss Warranty Act makes it illegal for companies to void your warranty or deny coverage under the warranty simply because you used an aftermarket or recycled part. The manufacturer or dealer can, however, require consumers to use select parts if those parts are provided to consumers free of charge under the warranty.

Still, if it turns out that the aftermarket or recycled part was itself defective or wasn't installed correctly, and it causes damage to another part that is covered under the warranty, the manufacturer or dealer has the right to deny coverage for that part and charge you for any repairs. The FTC says the manufacturer or dealer must show that the aftermarket or recycled part caused the need for repairs before denying warranty coverage.

 

Jimmbbo: Thanks for the informative response.

 

It is both informative and correct.

But we will see the issue argued again on this forum shortly.

 

 

+1 for Soler TC. I haven't installed the new LT5 TB yet, but I did install the Soler TC on the OE throttle body. Wow. That is pretty friggin cool! I was a skeptic, but it wasn't that much cost or work. Pretty simple. Yep, from Eco to Ludacris, it worked as intended. I can't wait to try this at the track (I'm avoiding launch control for now).
