Can some computer contro be eliminated?

Tacoma Drivers

I own a 2011 Tacoma TX Pro and live in Colorado and am off road at least three time a week if not more. While I'm pretty happy with this truck I'm absolutely NOT an advocate of computer control, especially some of the engine functions. I can accept fuel injection and the distributor/timing functions, but I find it absolutely exasperating when the computer takes control of the the throttle function thinking it knows better than me the driver. If I had realized the extent of computer control in the 2011 I would have kept and rebuilt my 2004 Tacoma.


So, I would really appreciate opinions on how much computer control, if any, can be eliminated by the right custom shop.

Thanks for your time
Bob

 

Any thing is possible with enough money.

 

Sell it and buy an older truck. Mess with your existing truck and you will effect resale value.

 

This simple mod allows you to turn off all the nanny systems on the truck (abs, traction control, engine management, etc). Quite simple and reversible. Controllable by a switch.

There are plenty of cheap and easy mods for your issues. ABS delete will solve most of them. Does the pro have ATRAC and locker? If not, do the yellow wire mod too.

Moondeath beat me to it.

 

Those modes won't solve his major complain of "throttle by wire".

 

Of course it will. Throttle by wire isnt the issue, the nanny systems are.

 

The OP's complain is throttle by wire.

 

Quote ", but I find it absolutely exasperating when the computer takes controlof the the throttle function thinking it knows better thanme the driver"

 

OP, sorry to say but everything now is computer controlled.

As stated earlier, throttle-by-wire can't be eliminated. And besides, modern vehicles' computer based systems (i.e. ECU, TPS, TPMS, MAF, MAP, etc.) are so deeply integrated into the vehicle eliminating it completely would entail essentially remaking the vehicle.

You can kill some things using a switch like ABS as stated above, but I don't believe that's fully what you want. If I am wrong disregard what I am about to say.

If you truly want to limit computerized functions in your car, look for and 80's or early 90's Toyota Pickup. They are some of the best trucks EVER made and have more what you like.

 

That is not throttle by wire, that is the nanny systems on the computer (ABS, ATRAC, TRAC, traction control)

 

Proof that some don't read the OP's first post.

 

This right here states "Takes control of the throttle function", that means (To me) that the driver is no longer in control of the throttle, which happens when certain traction control systems engage (Limiting throttle to 30 % or less).

 

Really, and we'll just ignore the more predominate system of throttle by wire that actually controls the throttle.

I done with this thread

 

OP stated that he is annoyed that the COMPUTER takes over the throttle.That is a nanny system. Doesnt matter if its drive by wire or not. Remove the nanny system and it drives like any old school vehicle. The mod is a fix to what the OP is annoyed with. Plain and simple. OP asked if there was any way to overide the computer system. The answer is the mods. They eliminate the computer from doing what it thinks should be done, and allowing the driver to completely control throttle. Which is exactly what the OP was asking about.

 

Thanks for all the info responses.

To be honest I did a disconnect between the fly by wire throttle and the "nanny systems". While I am "old school" and believe in keep things as simple as possible, the responses have made me rethink the issue. Fly by wire throttle is kinda OK if it truly is the "nanny's" being 90% or more the culprits that reduce throttle control. Dealing with mud, snow, slush and ice are conditions I WANT full 100% of the time control of the throttle and brakes, but the computer dose not see it my way and seems to always win out. I'm sure most of you probably know that already.

About the only functions I use is 4wd high and low, ATRAC and Dif Lock.

Resale is not my concern unless I could find a properly equipped TRD OR V6 2004 Tacoma with reasonable mileage I'd have to give it serious consideration.

I DO NOT need or want a new Tacoma with all the computer controlled crap that take over for the driver when the "computer" thinks it know better than the driver. Believe it or not I know how to step on the brakes to stop my truck, been driving for 50 years.

Cell phones are for me to call someone, not some one to call me except for a direr emergency and I do NOT use the phone while driving. Music, I plug in my IPOD and play megabytes of 50's, 60's and 70's rock and roll; I do not need more.

moondeath, thanks for the ABS kill switch mod. Had that on my radar but had not got off my butt to complete it, and I did not realize how much stuff it turned off. I now have new incentive.

TW is a great site and there is always great help a finger tip away, thanks TW members.

Lastly, I apologize for demonstrating a lackluster use of our English language in my first post.

Cheers

Bob

 

I personally did the mod that is shown above. It completely removes all nanny systems on the truck. Plus, its turned off via switch, so you can turn it back on if you choose. I did it because I was tired of the abs kicking in with snow and ice. Now I can lock up the tires if I choose. All the engine management systems, traction control, abs systems are completely disabled with that mod. Just like a vehicle from back in the day.

 

IMO the problem is exactly as 95 taco and moondeath stated. The throttle by wire is not the problem. The problem is the nanny systems are taking over the throttle and brakes as a means to assist with ABS, ATRAC and Traction Control. That also holds true with the simulated Limited Slip Differential. If the nanny systems are shut down the throttle by wire is just a throttle.
