2016 OVTune Tacoma 3.5L Manual Transmission / Engine ECU Reflash

Can he take all his luggage with him?

Disclaimer: I've mucked up my share of threads before, TBH

 

hey a little entertainment goes a long way. even w/o Dylon.

 

Dylon didn't make me want to hulksmash my monitor though!

 

But but but, he's an engineer.

 

Oh he's waaaay smarter than you....Just ask him.

 

My truck shipped with a bad CKP the dealer refused to diagnose and replace after repeated attempts. The result? Nasty tailpipe emissions from by brand new truck, smelly and sometimes nearly black. eventually a rough idle the dealer continued to say was "normal" I replaced the sensor on my own dime = problem solved. on stock tune my truck was always slamming into gears harshly (can't be good for the truck!?) and smothering itself... press down on pedal, nothing happens, then suddenly it realizes you wanted to GO and slams into 4th at 5k RPMs. nothing in my mind says MY truck was anything other than a hot mess of pollution and inefficiency as delivered by Toyota. Between the sensor replacement, cleaning my oily (from the factory) MAF, and tuning for a cleaner more linear burn I have recovered from the BS Toyota handed me.

Toyota would have had me driving around in a smog machine until it stalled on the freeway...

 

So am I, the difference is common sense.

 

not stirring the pot here, i have a couple things for you.

first, the moderator's "bye now" comment was an invitation to keep on repeating yourself, which will get you banned, like RIGHT NOW.

second, your comments about flashing and the dealers and what have you are uninformed. the info is available in the OVTune Alpha thread. you'll need to spend hours going through it like we have to get some answers. in the meantime if you value your ability to dialog here, stop repeating what you've already clearly expressed. please.

 

Oh crap. I'm an engineer also. . .

I hope nobody heard that.

 

@tonered I always thought it would be coold to drive a train.

 

My response? B/c I clear the learning by disconnecting my battery terminals periodically because I hate the way the truck "learns" shifting behavior over time. Honest answer as something I've done multiple times well before the tune! I also have a TIS subscription and have used it to flash w/ Toyota's stuff. OVs tune behaves just like a TIS reflash (as stated in the dev thread) and our warranty is NOT void by using TIS

 

Haha! Trains are cool.

Sorry for the OT.

 

I'll break down and respond to your entire message. Once.

Homologation testing on my tune has not been done, and it is not necessary. I have worked with companies that need homogolation testing done and it is almost always when a hardware part is changed and the software is set to match. If you aren't aware, our tunes are developed to work with stock vehicles. Where no hardware emissions component is touched.
Nothing inside the ECU that are the main controls of emissions standards are changed (like cam phasing for psuedoEGR), Catalyst safety margin tables, EGT temperature control, etc.

As I said in a previous page, and something an automotive engineer should be well aware of... is that almost all harmful emissions from vehicles these days are during cold start. Cold start control in our tune is left stock. Catalytic converters are very good at what they do in this day and age, and driving around at operating temperature produces much less. A majority of what we do in our tune is changing the driving characteristics through auxiliary controls, Like changing throttle opening dynamics. Changing the dynamics of the throttle doesn't change anything that comes out of the exhaust. Neither does changing how the transmission shifts in the AT.

I don't think you actually know that much about CARB or the CARB certification process, if you truly cared about emissions and the environment you'd want CARB changed. Many things get carb certification that are nowhere near the standard of OEM.

I am a 3rd party company that is not in any way affiliated with Toyota. Are you aware that the entire reason of reversing code is to understand it? Are you also aware that in certain manufactures the "logic" and math involved with the calibrations are identical throughout, and once you reverse and understand one, you're not going in and "reverse-engineering code they don't really understand." I'm sure you also know that nearly all ecus have the same controls and basic pathways for controlling an engine.

I don't think it raises any questions. This is America, not a communist country where you are only allowed to buy "state approved" car modifications for your off-road / race vehicle. Take california as an example. They are Regulation Zealots. But has it actually fixed the problem?

Are you aware that one of the main contributors to harmful emissions into our atmosphere is the beef industry? Do you protest farms?

How much do you know about the toyota ECU? Just because ecu "A" is easy, doesn't mean ecu "b" is identical. Like bosch ECUs with T-PROT protection. Just because bosch has T-PROT does that mean some obscure ECU out of a suzuki swift does?
A dealer can ask you any question they want. Why do you have those wheels. Why did you install that suspension. Why did your ecu get flashed. What they can't do is deny your warranty because they see a modified part or suspect a modification.

thanks.

 

Dude if you don't want to buy it then don't come on the thread for customers of OVTuned and talk shit about it.
Side note you're wrong about the tuning. The only reason it runs the way it does from the factory is because Toyota is held to very strict regulations. The regulations on the automobile producing industry are stricter than the rules for cars on the road for a variety of reasons (people own old cars, people mod their cars, govt can't force people to buy a new car or a fuel efficient one but they can force a company not to make them), meaning that without directly breaking the law one can modify their car beyond the way it was produced. It also means that manufacturers leave a lot on the table ONLY for the purpose of making vehicles more emissions friendly. A car running rich actually produces fewer NOx emmissions than a car running lean, which is a higher concern than CO2 emmissions. While it is fairly common knowledge that a car running rich also is in general more reliable than one running TOO lean, running 12.4-12.7 AFR is far from too lean. Also, running too lean is only dangerous when you have no way to control it and keep it cool, but this truck has no such problems with it's massive crank driven fan and HUMONGOUS radiator, as well as auxiliary coolers for other important systems, and coolant veins that run through the engine block and even around the exhaust headers before they exit the block. Not to mention forged crank, conrods, and pistons from the factory to limit thermal expansion differences which could eventually lead to reliability/performance issues. Toyota has built in failsafe after failsafe to make this truck bulletproof, and without sacrificing hardly anything to that end, Matt at OVTuned has worked tirelessly for months now to perfect the ECU tuning of this truck and many other vehicles from the DRIVERS perspective, not the Govt's perspective or anyone elses. If it's not your cup of tea then nobody said you had to buy it. We all did, and we all enjoy the results of our purchase, and speaking personally I would recommend this tune to anybody who owns the truck purely for the reason that the vehicle is much easier to drive and more predictable with the tune, which make it safer to drive. It's also faster, and sounds better too so I see no downside.

Not the thread for your opinion of the product anyway, nobody asked.

I can confirm, have been getting factory maintenance done for 5k miles including now two factory services without so much as a question about the engine tuning. The tech did say it was the best driving Tacoma he's seen so thanks again @OVTune

 

Dead... Thanks for posting
