Professional ECM Unlocking for Your Duramax Engine

At PistonTwistin LLC, we specialize in LBZ & LMM Duramax ECM unlocking services, ensuring your engine control module (ECM) is restored to full functionality. Whether your ECM is locked due to communication issues, tuner restrictions, or custom keylocks, we can help!

When Do You Need ECM Unlocking?

✅ Non-Communicating ECM via OBD Port – If your ECM refuses to communicate through the On-Board Diagnostics (OBD) port.
✅ Handheld Tuner Lock – Locked by a handheld tuner you no longer have access to.
✅ EFILive Custom Key Lock – ECM locked by an EFILive programmer, displaying error code $0537: "Controller is locked with a custom key."

⚠ Without the correct unlock key code, these issues cannot be fixed until the ECM/PCM is unlocked and reflashed.

We utilize a non-invasive bench software method, unlocking your ECM without disassembling the module.

Ergonomic and well made.
I have at least a half dozen ball launchers and this is the nicest one. As efficient as any of them and it feels the nicest in my hand. As long as you tighten the handle when you put it together, it will serve your puppy well.

Ball Launcher Poorly Made and Hard To Use, Save Your Money
This launcher was too long and thin to pick up the ball from the ground, I had to use my other hand to press down on it. The screw on handle was heavy and kept coming loose no matter how tight I made it, strain on the wrist to use. The ball holder end would often not let go of the ball when trying to launch it. I ended up putting it in the trash. I had two shorter Chuckit launchers that are much better made, will stick with them. I don't recommend this to anyone, save your money.

Go Get It!
GoSports does it again. Our family has a lot of GoSports products. It brings us comfort knowing when we order a product from them the quality is going to be great. The Ball Launcher is excellent. Our lab loves the soft tennis balls that come with it, preferring them over the harder rubber ones from other brands. The launcher itself is thoughtfully designed, well-made, and comfortable to hold. Our new go-to for daily fetch sessions.

Gave it a Try
I have always used the Chuck It ball and ball launcher. I thought I would try this since the price was better. There is definitely a reason it is priced lower. The handle on this one twists on and constantly comes undone when you throw, and it does not launch nearly as well. I would not order this product again.

A few usability issues
My dog is obsessed with playing fetch. It’s part of our daily routine. Pros - I like that this comes with two launchers so we can keep one at home and one in the car. - Build feels solid Cons - The cup is slightly too small for regular sized tennis balls. I buy the large Costco box of Penn tennis balls every couple of years for my dog. If you fully seat the ball in the cup/launching end, it’s extremely difficult to throw and puts some strain on your wrist. — the workaround is to only partially insert the ball when picking it up. - Like others have stated, the launcher does come unscrewed occasionally after a few throws. It’s kind of annoying so I’ll likely try some thread lock, but ideally that wouldn’t be necessary.
