And just like that the Tacoma 3rd Gen platform Blackhawk tune is back and improved. Feel free to reach out for any questions. Have a great day everyone!
Good afternoon from the YotaWerx Tuning Team.
Following the recent release of YotaWerx “Blackhawk 2.0” for the 3GTacoma 3.5L, we became aware of an issue with the calibration for the 6AT files. At this time, this issue has already been addressed with VFTuner, which entailed the changing of values within various tables on their own. This is something we first encountered with alternator output tables when applying AGM-profile adjustments.
Initially, we encountered issues that we determined to be limited to the 04C21 ECU ID (2021-23MY 6AT), and not present at a 100% rate of occurrence. We assumed the source of the issue lay with ourselves and began to work accordingly towards a solution. As time passed, the same issues were discovered on older ECU IDs, albeit at a significantly lower rate of occurrence. In the ensuing testing and investigations, we encountered evidence of VFTuner software modifying tables on its own (again, this is already addressed and no longer present in VFTuner). We also identified the extent of where these issues were presenting.
At this point, the tune was already broken down in several ways which granted the opportunity to offer a superior calibration option with effective and consistent power delivery, without losing out on the impressive power benefits displayed by the initial 2.0 release. This included multiple dyno sessions along with extensive road testing amongst partners and independent testers for evaluation of drivability and reliability.
On 20 April 2024, we got on the dyno with a 2022MY 3GTacoma 3.5L 6AT for final adjustments to the Tacoma 3.5L “Blackhawk 2.1” tune.
Like its predecessor, these BH2.1 numbers below were measured at the hub rather than the wheel, and all posted dynographs include relevant details regarding ambient conditions and other variables. Most notably, these runs were all conducted with 91-octane and in 4th gear for a true 1:1 gear ratio. Due to using a hub-dyno, the vehicle’s tire size is removed as a variable.
This dynograph serves to display a comparison of Blackhawk 2.0 vs 2.1, demonstrating that we successfully achieved our goal of not compromising with a loss of the desired power that this calibration is well known for.
YotaWerx Tuning extends our gratitude and appreciation to VF Tuner for the dedicated support and technology available to us, making it feasible to provide a superb example of using VFTuner tuning software to bring excellence in tuning on this platform to the community.
