For the next 4 days only, through 9/8, COBB Accessports are 10% off, and I’m stacking an additional $100 off CAMTuning Custom Tuning when purchased with an Accessport.
That works out to $177 off the normal Accessport + Custom Tune package price.
This is the biggest discount I’ve offered on a...
That sounds like a different behavior than the cold 1-2 shift I’ve been working on.
On the hybrid trucks, reverse engagement can feel different depending on whether the engine is running or the truck is operating in EV mode because the hybrid system is contributing to how torque is being applied...
Yep, and thanks for taking the leap. You can reply directly to the email you received from my tuning support address when you placed the order. That’s the best place to go deeper on the technical side and keep everything tied to your 4Runner.
On the AFR question, I wouldn’t say it’s purely...
Good questions. This is the hybrid, so that low-RPM torque number isn’t coming entirely from the turbo. The electric motor is contributing quite a bit in that area too.
I’ve pushed my own development truck considerably harder than this calibration, and on these dyno pulls wastegate duty never...
Best downpipe available. The dyno sheet on their site is from my independent testing on my truck. I got the first one produced and have tuned loads of them. The fab work is better than anything else on the market.
I have tuned quite a few of them. I chose one of them to test and have sent them a map today. I expect it to behave the same as the other platforms. Do you own one, or know of someone who does that has the issue?
You’d need the COBB Accessport and one of my tuning options here:

I'm currently matching Cobb's 10% off on their Accessports, and the discount is reflected in the cart.
If you already own an Accessport, I have options for that.
For a stock or lightly modified...
I appreciate that. I’m really just a curious mechanical engineer who got into tuning almost by accident about 20 years ago, and somehow that turned into this. A lot of what I enjoy about it is exactly what you’re describing—trying to understand why something behaves the way it does, then...
It does appear to be calibration related. Toyota handles some things differently immediately after startup, and I’ve identified a change that so far seems to improve that first-shift of the day (or long sit) behavior.
I can’t say whether Toyota had a specific reason for programming it that way...
It may be all of them, but maybe not everyone is bothered by it enough to mention it. I’ve read countless accounts of it on the forums and social media.
I can, but not without revealing enough to give other tuners what they need to duplicate it. It is primarily torque converter behavior though.
Is your 4Runner one that suffers from it?
One behavior I have continued to work on with the hybrid Tacoma and 4Runner is the hard first 1–2 shift after the vehicle has been sitting.
Owners describe it in different ways: a jolt, thump, surge, or unusually firm shift. The common pattern is that it happens on the first drive of the day...
