Soler Throttle Controller Issues
Just wondering if anyone else has had issues with their controller. I received my controller the other day and read through the installation instructions as well as 3 different install videos. I opened everything up on the car and didn't do anything for more than 10 minutes. Took about 20 minutes for the install and then I went for a test drive. Everything worked as advertised and I was really impressed with the results. A couple of days later, I took the car out for another drive. Got 1 1/2 blocks from my house and was stopped at a intersection with my foot on the brake, and the rpm started increasing rapidly towards the red line. I quickly put it in neutral and the rpm began decreasing. I checked my phone app and it was still on sport 6 where I left it from the last drive. Took me 10 minutes to get the car home. Didn't matter what mode on the Soler phone app I was in, or what mode I was in on the car, even reverse. Luckily I was close to home and not somewhere in heavy traffic. Anyone else have something similar happen?

New unit is on the way. I was just wondering if anyone else had experienced anything with theirs other than a CEL. I had no lights or codes at anytime, just runaway rpm.

I had one and sent it back. It would occasionally cause a slipped shift in higher gears. I used to have a video of it happening. The 4-5 shift would have a rev during the shift like the transmission got confused. Took off the Soler and never happened again.

How about clunky transmission issues ? I added one on mine and it’s been fine then today when I started it, I had a few times when moving from a stop it clunked as if it was jumping back into gear as I started moving. I’m going to see if it does it again tomorrow. If so I will remove it and see if that makes the issue go away.

Zero issues on mine and its been installed on two 3lz's (moved it over)....and if I didnt have this Soler TC on the car- I swear the Z06 would be less fun. GM really has a mushy pedal but then again Im used to a more aggressive throttle like that in BMW M or even AMG.

I had the exact problem as the OP. It scared me when the rpm’s kept climbing as I was taking off from a stop and it wouldn’t shift into 2nd gear. It did the same thing a few weeks later leaving a parking lot. I called Soler and they acted like they’d never experienced the problem before. Mike built another unit and sent it to me and I haven’t experienced any more problems.
I’m glad it’s functioning correctly since I regularly use it to lock the throttle for security.

Run-away throttle is exactly why I will NOT muck with the throttle signal with a non-OEM certified device. This is going to end up causing a wreck or worse. I've read a numerous posts around here and other places about this happening, so there's no way they can say it's been never heard of. Especially when these people contact them and get a replacement and this is nothing new.
One of the main issues with the throttle response is not actually the mapping anyway, it's the TB. There's a ridge on the inside that the blade has to get past. Putting a ported TB on there will make it drive properly and you won't feel the need for a controller, unless you just want it to be crazy sensitive or have all your throttle in the top half of pedal movement for some reason.
Changing the mapping in the tune would be the only way that's safe, but sadly we can't do that yet, if ever.

This is not new technology. I have been running things like Peddle Commander and BD Performance throttle booster in my trucks since 2014 with no issues….I am talking over 150k miles of trouble free performance…That said I don’t have any experience with Soler’s similar product….

As far as reliability. This is a forum. There are a few threads of some people that had and issue and the company immediately fixed the issue no questions asked. That's the kind of service I look for. Any way. Now all of sudden its threads like this trying to portray some big issue that doesn't exists. What's funny is the people in this thread doing all the squawking, are individuals that are kicking the tires sort of speak.
Its good to do your research. On the ported throttle bodies. It really doesn't matter which manufacturer you go with IMO. They are both going to give you a smoother throttle response.

The throttle controller is way better than a ported throttle body. Hands Down. Not even a conversation. You want the car to respond to throttle immediately and get rid of dead spots and low end lag. Get the throttle controller. You want to smooth out the throttle response and remove just a little bit of the lag. Get the throttle body. I have them both.

And I agree about forum mentality and issues... people always will mention their issues but its more rare for someone to just post "Damn my car is doing just fine".

I have a '23 from new and the non- linear OEM throttle settings were not confidence inspiring to say the least when pulling into traffic or out of a side road. Installed the Soler controller after the 1st month and it has worked like a charm much better than stick settings. One of the best and definitely the cheapest upgrade so far.

I have both the Soler Throttle controller and the ported throttle bodies, (knock wood, no issues at all) I will say the car is quicker than ever and the throttle response is terrific.Smiles per miles ratio is very high! No issue with RPM creep. Still a fan of Soler performance.
