Absolutely, We are fully committed to supporting hybrid platforms in the Tacoma, Land Cruiser, and the upcoming 6G 4Runner. While we’re in the development phase and still fine-tuning our Hybrid calibration variant, we’ve got internal test vehicles in action to ensure we get it just right before...

Please send me a PM with your contact information. We can discuss further details off-line. Peak boost pressure was functionally identical. Part of our tuning is eliminating the boost taper in the stock calibration, allowing the truck to maintain the stock boost pressure to redline.

We embrace a tuning philosophy that enhances drivability and performance while preserving the reliability and durability that Toyota engineers meticulously design into their vehicles. Our approach is to "trim the fat," optimizing performance without compromising the foundational quality that...

The baseline we provided is how the truck was delivered. Despite the Dept. of Energy's statements there, the fact is, 85 octane is THE "Regular" grade fuel here, and it's what a significant proportion of the population uses. $ talks for most folks, and 'Regular' gets you from A-B just the same...

Sure thing! I'd like to clarify/provide some context here just to keep everyone on the same page and keep any future comparisons in perspective. The "as delivered" run shown below (Red) was on 85 octane. Here in Utah that is "regular" grade fuel due to our elevation. Not 87 octane as most...

Tyler, Thanks so much for the support and kind words! I'm just as excited as anyone to get this out to the 4G community. I promise to keep everyone posted the moment we're ready to go live! We still have a lot of R&D to do on the hybrid integration and controls. These are new-generation ECUs...

Mike, Thanks for the support on the 3G! Our flashing method/protocols for the 4G will not trigger or report an RoB event, which we specifically wanted to validate. There is no "record" or stored data reporting that the ECU has been flashed, so nothing would indicate to a dealer technician that...

*Generally speaking* here, the way Toyota's ignition/knock control strategy aims to keep the engine as advanced as possible on a given fuel, the ECU will generally run more ignition advance and remove any knock based fueling enrichment when using favorable (higher octane) fuels. This will often...

We're in the process of evaluating the manual calibration data, but as things stand, I believe manual calibrations will have the same net gain (potentially slightly more). We'll be sure to report on this as we dive deeper into the manual calibrations. More to follow on this. Great question...

The results above are on an adaptive calibration, meaning you can run all regular grades (though we advise 87+) through premium without needing to retune the truck. We'll be sharing performance data on how this adaptive file reacts to 85-91 Octane shortly.

ECU Reflash.

This was on 91 Octane. We certainly appreciate the benefits of E85, but it’s important to note the Tacoma is not equipped with flex-fuel capabilities. This means it lacks the ability to automatically adjust fueling based on the varying ethanol content found at E85 pumps, which can range...

We know many of you have been eagerly reaching out about the latest developments for your 4th Gen Tacomas, and we appreciate your enthusiasm! While we’re still fine-tuning a few elements and conducting essential tests before our official release, we couldn't resist giving you a sneak peek at...

Welcome to the home of the 4th Gen revolution. Overland Tailor Tuning (OTT) has been the leading brand for Tacoma tuning as well as other Toyota platforms for the last several years - and we are hard at work. We are excited for all of the changes the new generation brings to the market! At...

The above tests were done with pump gas from the same Shell station, which has the common "Fuel contains up to 10% Ethanol content" label. (y)

Hello Tacoma4G! I almost made a new thread on this topic, but I thought we'd chime in with some data and observations we've made on our newly acquired 2024 Tacoma. When we picked up our truck from the dealer, they were kind enough to top it off with Utah's finest 85 Octane. The vehicle's...
