First Gear Load Control – Cobb Platform Update

[CAMTuning]

There’s been a lot of discussion around first-gear load limits on the T24A platform, so here’s a clear update.

This applies to the hybrid as well

Earlier calibrations had a defined load ceiling in 1st gear. That meant even if boost targets were raised in higher gears, the ECU would limit commanded load in 1st as part of its torque management strategy.

Recent calibration updates within the Cobb platform have expanded access to those control tables.

I’ve validated these changes on my development truck and multiple customer vehicles this week. With the new tables properly calibrated, full commanded load and boost can now be achieved in 1st gear when appropriate.

A couple important points:

• This is not about simply “removing a limiter.”
• The ECU still models torque and protects the drivetrain.
• Proper implementation requires balancing load targets, torque request, and boost control to maintain smooth delivery.

Done correctly, the result is consistent acceleration behavior across gears without artificial first-gear suppression.

For clarity — I have tuned these trucks with Cobb since the beginning, and I will continue to tune with Cobb. It remains the most transparent solution for this platform, and development within the ecosystem is ongoing. I’m actively validating these updates as they’re released and integrating them responsibly into customer calibrations.

As always, the goal is controlled, repeatable torque — not just peak numbers.

New to the 4th gen and its mods. Never a fan of nanny type controls no matter how they're labeled. My truck's sole purpose is 10 day Rocky Mtn Elk hunts usually in knee deep mud and rocky ledges. So big fan of low end torque.

So new 26 TRD Pro without mods except for 35" Mud Terrains what is my best route, or necassary software/hardware?

You're also local!

You'd need an Accessport to get started, and custom tune to maximize gains. If you're in the ABQ area I can dyno tune it for you. If not, remote is how I am doing 90+% of my tuning.

I have 35 inch tires too. The Cobb tune with the recent update installed by CamTuning can't be recommended enough. This latest update is really excellent.

Just curious, does that apply to manual transmissions as well?

I just purchased an Access port. Will be arriving this week. Will the updated OTS tunes be available with the higher 1st gear load limits? Or will they require custom tune to gain access to them?

thanks

The off the shelf maps do not yet have the load limit lifted and I do not know of a plan to add that. I’ll confirm though. Please feel free to PM or email me if you’d like to discuss tuning options.

Thanks for the reply. I think I speak for most owners that the 1st gear load limit has got to be the most annoying thing about the stock tune and should be included in OTS tunes. I feel like if that's lifted it will improve acceleration significantly even on stock calibration. I had the OTT tune previously and found it to be extremely frustrating because of those limits. All that power on tap being held back is just horrible. At the time they told me the hybrids didn't have the load limits but I could tell otherwise. Their non hybrid tunes did get a raise in the load limit but not the hybrid, so I went back to stock at that point.

I confirmed with them at Cobb and there will be no changes to the off-the-shelf maps

Darn that's a shame. Thanks for getting back with the response so quickly. I may reach out for a tune at a later time then.

Sounds good. I’m always willing to discuss or answer questions.
