Our Lady of the Highway

I usually hate when people say this... but did Friday come early?

 

the absolute state of the goofball people that post here never ceases to amaze me

THINK OF THE CHILDREN, THE HORROR

LOL

 

Yes, it's 'ol Kitty's Friday.

 

Here at Tacomaworld™ the

is the guy who says modding your Factory-locked ECU with literal hacked garage software, and tampering with the hydraulic actuation of the clutch is simultaneously unnecessary as it is objectively stupid given the grievous consequences of such actions.

My track record includes objective, fact-based data about the dangers of "spacer-block" lift kits over time, extended springs with incorrect weight ratings used as "lift devices" and cutting into the gearbox because your AT 'feels sluggish'.
but because I dont bend at the waist for the idiotic culture that pervades this place, im "BAD"?

(see post#10 for the Tacoma ECU decision tree as evidence!)
Imagine the kind of high and mighty 'hubris' one would posses to suggest they just outwitted all of the TRD departments 6-figure salary Engineers with an app in their garage.
Do you really think Toyota wasnt capable of simulating and production-testing the very ECU and clutch configurations you people mention?
do you really, REALLY think that?
I hope some of you realize that Toyota is governed by National and Global requirements in dozens of different markets thier truck hits, that makes bespoke engine tuning packages infeasible. Thus, thanks to the liberal babies of the world, who operate on feelings and emotions instead of reality, TRD must engineer their product to meet conspicuous 'guidelines' set by politicians and 'experts in the field" that result in your 'sluggish' AT or whatever you people feel in the clutch

But hey, this is all imho

 

Are all Toyota employees this smart?

 

I REALLY do think that Toyota, limited by corporate bureaucracy, EPA standards and trying to appeal to the masses would DE-TUNE the truck and make it limited. There is a reason aftermarket companies exist... they IMPROVE and change factory limitations to make vehicles better, more capable, etc.

Of the THOUSANDS of trucks that are OVT/ADM NO ONE has had any issues. So, I am not sure where your unfounded fears lay?

For the record, it's the LACK of feeling in the clutch that is the problem with the accumulator. I am sure such a well educated, experienced professional manual transmission driver, such as yourself, can understand the desire to feel the clutch as best as you can. Especially for those who actually off road their trucks/tow and back loads and trailers etc... Clutch modulation and feel is a nice perk.

Perhaps that's just for us inexperienced and uneducated gearhead swine though with our hacked garage software (still have ZERO clue where you're coming from with that one... there are entire industries revolving around the automotive tuning software theater.)

 

Your thoughts on the gear ratio in reverse? Or was that to keep the T Racing D in mind when in reverse?

 

I'll describe for you the primary function of a "Hydraulic clutch accumulator":
mechanically, the accumulator allows for more predictable clutch engagement time-over-time, in alll feasible drive-load scenarios.
A stabilized variable is always a more desirable engineering outcome.
Toyota is trying to engineer out every Tom, MOC221 and Harry's subjective take on "how to work a clutch" and "how a clutch should feel", in recognition of the fact that many peoples level of experience an ability slipping a clutch has a great deal of variance, which wears on the components in different and novel ways that they are mitigating for.
Vehicles with "high" relative torque and/or "tall" first gears often have them to protect the drivetrain, especially in Truck applications that MAY include towing, extra weight etc...


so for those of you that "actually off-road or tow" with your truck, retaining the clutch accumulator will (in theory) stabilize clutch-actuation across the infinitely varying conditions you will come across in the real world, increasing the likelihood the clutch will live out its designed life-cycle.
REMOVING IT, will increase perceived "pedal feel" potentially at the expense of consistent regulation under high-loading scenarios.

I had a long, detailed response I spent 5 minutes typing up... And Then I realized, what's the point? You'll just explain to me what the parts do like I'm an idiot and was never a mechanic. Tell me, How's the view up there from your soapbox?

 

Imagine actually believing the Toyota Truck engineering department doesnt know exactly what they're doing
lol
and so much so, that random people on tacomaworld are capable of "improving" on their ECU and Drivetrain work using their home PC in their garage.

 

Before the ADM, one of the things that i noticed was, my clutch would "shudder" a bit when starting up hills. With the ADM its completely gone and clutch engages perfectly, no "shuddering". So what does that tell me? The accumulator slows down the engagement of the clutch, when it needs to bite quicker. Instead, the clutch bounces off the flywheel a few times. Sure is no good for the clutch's life.

Also, not sure if you rev match, but with the accumulator it was a lot of guessing and a lot of times there was a clunk. Again, uneccesary stress on the drivetrain. Now, rev matching is quick, predictable and smooth. The best mod i have done to my taco.

I was thinking same way like you for the longest time, that engineers designed it to work with the accumulator. There must be a reason to for it to be there. I was afraid to do it for the longest time but i was annoyed how incosistant the clutch was.

Anyways, im super happy i did it. I honestly think its only installed for people that are not experienced drivers, so they dont shock the drivetrain or fuck something up, then complain to toyota. My previous truck had no accumulator and the clutch worked beautifully for 7 years.

Nice truck btw man!

 

Cool, now do reverse gear explanation

 

Using files that a professional automotive tuner developed. Millions of people do this across all vehicle platforms... Every clapped out Cummins that has invisible trailers and belches black smoke has been tuned and turned up by some "random people." Yes, I'm aware that the black smoke is a sign of too much fuel and a "smoke screen mode" on most tuners and not meant for long term activation.

Toyota realized what they initially wrote as a tune was garbage, and had to rewrite it several times and release as a TSB, which dealers argued against and refused to do...

We were able to flash those exact TSB files early on, and now we have improved fuel mapping/power bands and engine management with an increase in power, efficiency/MPGs and my calibrated ass-dyno agrees with the actual dyno that there is indeed positive improvements. Toyota KNOWS this tune exists. If it was such a risk, there would be a huge push by Toyota to stop it... With recent ECU updates and the 2020 truck, it appears as if Toyota adopted some of the changes made to the code.

 

Yes... that Shuddering is THE most annoying thing ever... when it happens under load, it feels like a jack hammer is under my truck. It has done it when I feather the clutch, or when I drop it and anywhere in between. The accumulator makes it so an EXPERIENCED driver that wishes to do more than just Push clutch-shift gear-release clutch cannot do things such as rev match, double clutch, hill hold, heel-toe etc...

The shuddering on a sketchy off road off camber hill climb is absolutely terrifying.

 

So let me get this straight:
"We" (you) took existing Toyota source files, improved upon them in every meaningful way, on virtually $zero budget, in your free time and somehow Toyota hasnt employed you or bought you out? You actually think this?
This is the definition of child-like ignorance.
Toyota isnt trying to "stop it" because its of infinite irrelevance to an entity of their size, whether or not a handful of users on an enthusiast board want to tamper with their trucks ECU.
I hate to break it to you, but Toyota isnt adopting YOUR changes, they are harvesting the results of MILLIONS of vehicles sold worth of data points, and making appropriate changes to programming and code against actual-world analysis. I assure you, Toyota is beyond aware of what every possible permutation of ECU code can elicit for short-term gains. You havent shown them anything new with utter certainty.

 

Fancy

 

I love you 3rd gen forum. ♡

Because you're always a....

 

No. I didn't do anything. The PROFESSIONAL did. All I did was flash. You really don't know how this works do you? I never claimed to have done anything myself. You really are dense aren't you? Keep adding TRD parts to your truck and calling it a build... I bet you're getting ALL the GAINZ.
