Session 13: E30 Ethanol Tuning Explained: Power Gains, Fueling Changes, and How to Mix It Correctly Since I've been tuning more trucks on an ethanol blend lately, I figured I'd add an entry here to cover that topic. A lot of people think running E30 is just adding ethanol to make more power...

Let me know. We can talk about it more over PM or the phone even.

It's all very dependent on your right foot. A lot of times mileage will drop a bit during and after tuning because the owner is enjoying it a little too much. I have about 11,500 miles on my truck and it has been tuned since it had 3,000 miles on it. I can still manage 20 to 21 miles per gallon...

Yes I do and once I have a good idea on when support will be available, I will be buying a truck so that I can do development on my own vehicle before bringing it to market.

I bet you I could change your mind about tuning. I can leave your power stock, but improve shifting behavior and it will change the entire driving experience. Take that with more power and torque and you’ve really done something.

I'm back with the information I promised I would get. I spent almost three hours on the dyno, letting the vehicle cool down between runs, and I took the best of four runs in all cases. One thing that I have characterized on both the 4Runner and the Tacoma is that the first run after an ECU...

That's pretty impressive. I have made that drive many times.

It’s like the saying “you spend 10% making 90% of your horsepower and 90% making that last 10%”. This falls into the latter category. They look nice but won’t do much if anything at stock turbo power levels. I’ll have a set soon and will do some on dyno testing.

Recent discussions about what custom tuning really is prompted me to try a fun way to explain it. So I made a quick video (yeah… with cartoons - AI is wild) that walks through the entire process start to finish in a way that’s easy to follow. What it covers: Accessport shows up at your door...

purely cosmetic. There won't be any power gains.

Much nicer than the factory tubes for sure. When I see these (and not just Banks), I wonder why they did not integrate the silicone coupler into the aluminum part that snaps onto the factory fitting with the clip. It would eliminate 4 hose clamps from the entire setup.

What are you trying to accomplish? Are you looking to read codes or monitor real-time data? Somebody mentioned the BlueDriver and I have had one of those for several years and it's a great all-purpose tool. For the 4Runner you really can't go wrong with the Accessport because it provides all of...

Also I missed this one earlier. ChatGPT gets it wrong a lot. These ECU's do have an octane learning- it's called the KCLV, or Knock Control Learned Value. I made a post about it here...

It will be the same 4Runner, same dyno. I’ve already done multiple runs on 86 octane. I always take the best of three since there’s a few hp of run-to-run variation. Also worth noting—the first pull after an ECU flash is consistently lower on this platform, so I don’t use that one. If Toyota...

If I provide real dyno data and data logs from the ecu will it change your mind? The ecu has authority to adjust timing based on octane and will without a doubt make more power. I’ve been tuning 4 cylinder turbo engines across multiple platforms for 20 years.

While it wasn't the intention of this post to create a debate, I love a good technical discussion. Thanks for all the participation! This same 4Runner will be going on the dyno next week. We will repeat the stock tune pulls on 91 octane and then re-tune it on the 91 octane tune that I did...

Cobb released a big update today, and the 2 key items worth noting are: 1. Full MAF scaling control. This means we can now tune for TRD Pro intakes on non-pro trucks, and aftermarket intakes can be added to the Pro or Trailhunter. This is huge. 2. Transmission temperature has been added as an...

1-year update on the truck. Just crossed 11,500 miles. Still my daily and it gets driven and logged constantly. This has also been my main test platform over the last year. A lot of dyno time, a lot of back-to-back testing, and a lot of real-world miles to validate changes instead of just...

I just finished a trailhunter for another guy and he took a long road trip this weekend. He recorded slightly better fuel economy than he normally gets. It's hard not to have fun with the skinny pedal when you get some new power though!

LC250 support is also available now, if you have one and hadn't seen it.
