    and more

    Example Driving 1.02C Shift map A





    You will be receiving 6 files:
    1.02C shift A All gear shift
    1.02C shift B Gears 1-4 shift change
    1.02C shift C Gears 2-5 shift change
    and 87 octane tunes to match


    Older updates below *************

    1.02C Automatic - check red text


    Tuning Kit information -
    - All kits will now be delivered with 1.01B, 1.02B and 1.02C (pending release)
    - Our kit offers reflash protection. No ECU removal required, no fear about bricking your ECU.
    - Our kit offers extensive support.
    - Our kit will be offering an OEM proprietary PID datalogger to capture important drivetrain data
    - Our kit offers free updates for all our standard updates (1.01, 1.02, etc)


    1.02 Calibration file is a collection of all 1.01A/B Research combined with 1.02 Valve Timing enhancements + other table adjustments.

    1.02C will incorporate all previous ECU calibration version developments and will include gear specific up-shift map calibration changes and routines for every gear.


    ECU and TCU Calibration Information (MT, AT) and changes
    -Ignition control / Ignition Timing
    - Fuel Ratio Targets for high load
    - Direct injection fuel timing and amount, compensations
    - Valve timing (intake, exhaust)
    - 16 way Torque control for Shifting (Automatic) (enhanced shifting)
    - 16 way Throttle progressive learning control
    - simplified Throttle linear calibration (Manual)
    - 1200 Breakpoint 100x 2D Shift Control Tables (Automatic)
    - ECT Mode driving enhancements
    - ECT Mode Throttle enhancements
    - D Mode throttle enhancements (Automatic)
    - 16 way shift torque maps (shift smoothing) (Automatic)






    power figures below with information about 1.01 A and 1.02 development

    stock baseline of two runs put the truck right at about 221-222HP to the rear wheels.
    The engine power is surprisingly very similar to the 2GR FSE 3.5L variant in terms of peak torque and peak HP with a majority of power being up top, makes sense as it is a 2GR variant.
    notable info :
    below about 4000 RPM we could see toyotas throttle ramping before full throttle

    6itkrq_183273c5c320adf9b4da3d5a94801ffbb6156677.jpg

    changes to the tune are:
    Alpha 91 octane reflash for stock rev limit
    ignition timing / fuel / camshaft / gearbox control / ECT throttle mapping / non ECT throttle mapping / torque limitations mapping and more
    -ECT adjustments and ECT throttle mode adjustments
    - non ECT throttle adjustments

    We did about 60-70 runs / drives collecting data in ECT / non ECT, etc so we could tailor throttle adjustments, which was more important to us and the owner of the car than just maximizing gains.
    here are some runs throughout the process showing increase of adjustments (not all of course)

    main adjustments to fix mid range torque
    2qukdux_c06129efc7c7e488e4b4f23bc08f66f342dfb234.jpg

    overall:
    we see very large gains possible throughout the mid-range 20-30+ ft lbs increase from 2700 RPM onward, with midrange HP following suit.
    Top end gains (with only mild adjustments) around 8-9+HP increase on stock rev limit
    the focus: throttle adjustments and throttling control. (success)

    Release 9/6/17
    1.02 91 octane
    1.02 87 octane (minimal extra power expected, but all other features applied)



    3rd Gen Tacoma 2GR FKS Automatic Transmission

    1.02 Update Changes -


    Throttle - Minor
    - Torque translation for load (incremental)

    Fuel - Minor
    - mild enhancements to fuel above 5000 RPM

    Valve Timing - Major
    -Intake camshaft valve timing adjustment through the complete range of RPM from moderate to high load. Smoother Valve timing transitions from part throttle to higher throttle / high load.
    - Completely recalibrated Intake vale timing from 2000 RPM to rev limit
    - 4500-6500 RPM Intake valve timing calibrated for peak possible top end
    - 4500-6000 RPM Exhaust Valve timing recalibrated to sync with intake
    - Valve Timing globally adjusted for smoother moderate to high load response
    - 1000-1500 RPM intake valve timing adjusted

    Ignition - Minor
    - slight changes to ignition

    16 Way Calibration Throttle Progression Control - Major
    - Major update to 16 way Throttle control for high / moderate throttle "snap" (response)


    16 Way Shift Torque Learning - Major
    -16 Way Shift learn maps condensed (to 10) D mode shift enhanced (see below)




    Overall -
    Overall I am very happy with what we saw today with final testing for 1.02 on the dyno. We were able to further smooth our low to mid load torque and make some minor improvements to throttle/fuel/ignition. I am happy with what we saw today as well in terms of overall gains on the dyno with adjustments to valve timing and the difference in Intake Valve timing high load tuning.

    Overall we saw a difference of 7-8 wheel HP over our best runs with 1.01B. Note we are seeing lower numbers on the dyno today because dyno conditions today were extremely bad, extremely hot. This is with the truck running overall around 4-6 degrees less than before due to heat soaking (room temp was 90+), compared to prior when we were seeing temps in the 70s. So we have less power overall due to heat but still we made gains in this heat over our 1.01B.

    Our main focus here was 2 things : Valve Timing and Transmission enhancements. 1.02 Valve timing was COMPLETELY rewritten / calibrated for best possible safe power. We did not just focus on full throttle, our VVT map now looks nothing like stock, and it drives nicer and has faster response as a result. We will be watching with our tester to get some reported MPG numbers with this adjustment.

    Transmission, we've got good news and bad news.
    Good news- we were able to make some shifting improvements and make *some* of the 16 way maps condensed.

    Bad news- we cannot disable the learning. By making all maps as "1" the truck will not shift. By condensing to 4, the truck will not go past 3000 RPM in 3rd gear. We found no effective combination that would allow "normal" like driving and shifting outside of making a mild learning condensation (eliminating 6 of the 16 maps).

    Other News - So I tested the new 2018 Camry Valve timing, ignition timing on the truck (fuel targets look to be identical). Virtually no difference over stock expect a mild bump around 4000+ rpm. I'd bet my money on either the tacoma being "under" reported or the camry being "over" reported.

    Dyno results.


    My recommendation is to NOT take these numbers as "absolute best." Run conditions were absolutely horrible.
    Humidity 80% and temperatures at 90+*, Intake air temps logged at 25-30*+ higher
    I am happy to report even under these conditons the truck performed quite consistently.
    The gains over 1.01B under these conditions are from ONLY cam timing

    I will try to get all graphs over-layed at a later time. Dyno room was so hot I did not want to stick around. Overall the gains are not "huge" but I am happy with todays conditions and finalization to VVT I was able to make smoother delivery and better top end than 1.01B or Stock.

    Note once again - I tested 2018 Camry tune on the truck, virtually no difference.

    what will be the big differences from the basic tunes already out there for the 16+?

    Will it be traceable by the dealer? For instance in the case of a warranty issue-- is there a way to revert and clear any trace of it being used?

    My body is ready. I'm quite interested to see what you found out, and although I know it is a long shot I hope some of that could pave the way for an OTS tune for the 2.7 2TR-FE.

    Well if they can add some mpg, fix shift points and throttle response, I'd be in. But if the can squeeze a few extra hp/tq that would be a plus.
