The KDMax Claim
KDMax claims 20Hp and 33lb-ft over Stock on 87 Octane fuel. We’ll put that to the test.
The Truck and the Test Set Up
The Truck: 2018 6MT Tacoma, Stock 4:30 gears with 275/70/17 Falken Wildpeak E-load tires, 2” Bilstein lift with SPC UCA’s, Icon RXT Leaf Pack, stock intake with Toyota Paper filter, stock exhaust. Little weight in the back from a soft topper and some trail tools. Truck was filled with 91 octane pump gas from a Shell station.
The Test: Test 8 different calibrations on the same truck, same dyno, same fuel, same day, etc... Eliminate all variables where possible and establish that the runs presented are repeatable and representative of the mapping of that calibration.
Measures/breaks were taken to keep the ECT and IAT’s as close as possible to our control sample run (stock) to ensure all calibrations were evaluated under the same conditions. The methods for our test (in summary form) were as follows: perform at least 3 runs on each calibration to get a consistent baseline for each calibration, All runs counted for each calibration will have starting temperatures of ECT to +/-90deg C and IAT to +/- 40deg C, run through the tunes as quickly as possible while maintaining target temperatures to ensure environmental conditions were as consistent as possible for the duration of testing. Conditions for the testing were as follows:
Test Starting Conditions: 82.93deg F, 25.44in-hg, 28.52% humidity
Test Ending Conditions: 86.55deg F, 25.42in-hg, 27.31% humidity
Only the best run of each calibration will be compared with another.
Establishing a Baseline
Our first dyno chart shows 3 back-to-back pulls of the truck to establish our baseline.
This truck is consistent and performs on par with other 3G Tacoma’s that have been tested elsewhere across the country by various entities. See for yourself by Googling “3G Tacoma Dyno” and click on “Images”.
Here is this 2018 Manual’s best stock run versus our own 2022 Auto that was tested in the fall of 2022. Further highlighting that with proper controls, consistent and repeatable results can be obtained. As you can see these are solid and consistent runs between trucks with two different size tires, gear ratios, transmission types, and in different seasons.
Again, the same two vehicles as above using the OTT 9.0 Calibration. Both demonstrating repeatability in the results despite the differences in the vehicles and conditions. Thanks to SAE correction and proper methods.
