Drive by wire system is sh*tty

[YarisSedan]

So well today im trying to accelerate to get to the next lane. I push the gas pedal all the way to the floor. Nothing happens? I am like what the heck. About 2 seconds later then it goes. My other car with a cable to the throttle is instant throttle response. I wish there was a work around. I am wondering if my weapon r intake has anything to do with this. Perhaps the stock maf sensor close to the throttle can not measure that high of air flow that quickly and takes seconds to respond before the pcm realizes the throttle is at wot and kicks in.

[Nexus1155]

no, its just the dbw system in these cars are crap and are magnetic instead of brush type, so the only fix now is to get the blitz throttle mod or switch to dbc

[largeorangefont]

If someone could reflash these cars you could adjust the gain on the DBW system and make it react faster. For now the Blitz thing is probably the best option.

[1NZYaris1]

There was a thread on here prior to the hacking regarding this problem and how to fix it.
sorry i can't help any further , one question though are you running NST pullies ,as these also make a big differance to throtle response.

[PetersRedYaris]

I never noticed it was slow in my Yaris, but people keep saying this. Parhaps there are differences between cars...

[cali yaris]

Pivot makes a throttle controller as well, and it's a couple hundred bucks -- trying to find out more about it.

[CASTREX]

^^^ yeap. Saw it a couple of weeks ago. Looks like it even has more levels of adjustability then the blitz unit. And priced more correctly.
Blitz is way to expensive IMO.

This would make a nice add to microimage portfolio... :biggrin:

[Kaotic Lazagna]

My doesn't react that slow. It's not that much slower than the GTI I had either????

[PETERPOOP]

This would make a nice add to microimage portfolio... :biggrin:

[whooppee777]

if i wanted to blow, what is it $400, on the blitz throttle controller who would i have to shout at to get it? i know echo has 1.

[Stargate YARlantIS]

thats why i like my MT

[marcus]

that maybe for auto but i dont get that on the manual..

[PetersRedYaris]

Drive by wire is on BOTH the automatic and manual... Essentially, it has nothing to do with the transmission. It is the electronic link between the gas pedal and the throttle body. No throttle cable, it's electronic...

[cali yaris]

I'm working on it.

Whooppee, I'm a Blitz dealer, so you know who to ask :biggrin:

It is more pronounced in the auto because you wait for the throttle to respond, there there is a delay while the transmission downshifts.

[TheRealEnth]

This only happened to me once tho, 99% of the time it responds instantly.

oh goodie.

what i meant was the lag may exist on auto but manual is very responsive depending on what revs ur on..

[Stargate YARlantIS]

The MT seems alot more responsive though, just me.... Way back when I bought my 07 LB, I test drove both AT and MT.... I honestly only got about 6ft when I stopped in the AT and asked for the keys to the MT... that's just me I guess..

[mikenacarato]

that is awesome!

[Benggolf2]

Want to improve your gas mileage and acceleration?
Teach your right foot to "squeeze" down on the gas pedal; don't stomp down on it. :wink:
This is especially true for cars with automatic transmission.

[thatboyjer]

i thought this had happend to me the first time i got my MT, i floored it and nothing, until the wheels caught pavement and launched me...

Learning standard was an interesting experience ;]

[YarisSedan]

Okay kinda a update i solved my problem. Today i was adding new windshield washer fluid to my car and was looking at my intake. And about a week ago i took it off to clean the filter. I noticed the hose from the pcv to the intake was disconected. I dont know if it fell off from the engine vibration or i forgot to reconect it when isntalling my intake =). So i have a huge leak of unmetered air that is after the maf sensor. Crazy thing is my vehicle never ran funny or idled rough except for when i would mash on the gas. Surprised my oxygen sensor didnt pick it up and set a engine code.

So if anyone is experiencing this and has a aftermarket intake i would go out and check that first =).

[marcus]

theres the culprit...

[Tamago]

sounds like your car isn't running right

edit: just read the thread.. ;) my bad

[llimonce]

i have the same problem in my MT sedan.. but the blitz controller i´ts expensive to me..

i think it´s possible to calibrate the sensor located in the pedal.. i planning to calibrate that sensor soon

[YarisSedan]

Well this will go on my list of mods that i plan to do if i win the lottery, Blitz supercharger, blize throttle contoller, rear disk brake conversion and so on

[facebreaker1212]

The delay does bother me too...I have owned mostly manual transmission cars and I also ride motorcycles and still stalled that Yaris the first couple times I got in it.

I want that Blitz controller but if something cheaper comes out before I am ready to buy I would def consider it.

[mikenacarato]

ill have a good answer as to if the blitz unit works next week.

well does it work?

[mikenacarato]

havent receiverd it yet

[andruboz]

I used to think I was an excellent clutch driver. then I bought this yaris. I've stalled this car more times than my metro and festiva combined and I've only had it 7 months. At first I figured it was a touchy clutch but now i blame the drive by wire. they need to build a 10th of a second delay into the dang clutch pedal so it matches the gas pedal. :-) actually, that would probably make things worse.

[Klink10]

Got mine (Blitz TC), haven't had time to put it in yet. To many other mods happening.

[mikenacarato]

you will love it. i did!

[Klink10]

you will love it. i did!

Where did you mount the brain box on your install?

[Free Fly]

I was under the empression that the yaris came with self learning technology. Anotherwards if your looking for mpg break it in that way. If your gonna run the crap out of it break it in that way. I broke my 06 scion xA for mpg and it couldnt get out of its own way. I have been running the crap out of my 08 yaris and it never lets me down. I have never had my yaris choke up on me. Is this possible or am i stuck in a time dialation bubble?

[mikenacarato]

thats how i broke mine in. i plan on driving it hard so why wait to "break it in"?

klink- i mounted my main box under the steering wheel inside the dash. pull down the bigger cover under the wheel and from there run the wires to the pedal and then run the wires to your display, which i have inside my drivers glovebox.

[Klink10]

Mike.......thanks.

[mikenacarato]

NO PROB

[TheSilkySmooth]

It is more pronounced in the auto because you wait for the throttle to respond, there there is a delay while the transmission downshifts. Throttle response is SHARPER than on my cable linked cars. There is a lot going on in the ECU, not just throttle response. It will not go WOT if revs are low or timing retard due to ping/knock sense. Best thing you can do is keep the carbon off the piston tops (wail it and water it) and slippery oil in the cranckase with a real 88-90 ocatane quality fuel toikeep the timing at max adavance at low rpm; then it should be locked and loaded all times. This ecu will learn a FE mode due to driving style then you punch it and it says - FU guy! <or> THE SOLUTION: Take off the F.I. and put a string of Mikuni 28MM. from a crashed Suzuki 1000 cc GSX-R:wink:

[AznGouki]

Damn..I'd like a cheaper alternative though. 4 bills is too much. I'll try the nst pullies first.

[mikenacarato]

the pulleys did make a good difference. but when i added the controller afterwards...theres no comparison.

[ChinoCharles]

That controller probably improves track times quite a bit, eh?

[mikenacarato]

not sure. i would imagine if your track was twisty than coming out of turns would improve.

[ddongbap]

So I don't get it. Does this thing actually eliminate the delay? Or does it provide 90% of the throttle, during the first 10%, WITHOUT eliminating the delay?

[ztrack157]

+1

[mikenacarato]

it eliminates delay. the response is very quick now.

[dybbuk]

what i meant was the lag may exist on auto but manual is very responsive depending on what revs ur on..

I would say the same thing about my auto. If I'm driving conservatively(i.e. most o the time and punch it, there's a delay. IF I'm racing around town and keep the revs up the response is sharp as it can be.

[SilverBack]

Yeah I have this problem too, especially while trying to pick-up speed while entering or transitioning freeways. I have to shift down one more gear to match the traffic speed and prevent a wreck, at the expense of temporary engine strain.

DBC conversion sounds good right about now

[Klink10]

Finished my Blitz today and went for a test drive. All those problems are solved. I couldn't stop driving it....TC makes it a whole new car.

[marcus]

what about the reverse process i heard ur suppose to turn this off during reverse or buy a special kit.

[mikenacarato]

see other thread. :)

Hello. I just read your comments regarding the self-learning capabiloity oif the ECM for the 2008 Yaris. I own a new 5-speed 2-dr liftback. I had no idea bout these features and it seemed a lot faster when I first got it. Now it is doggy probably because I have not been driving it very hard for the first 4800 miles aI have put on it. My question is, it now too late for me to try to get more power from it if I start to drive it a lot hardner now and keep it up? This all is until I get my Blitz SC installed on it, which I just ordered. Please let me know. Thanks! rpalai

[davinelika]

We in Indonesia use Dastek Unichip with Throttle module to overcome this problem... The throttle module function is pretty Cool!! Just kick your pedal half and your car will run like full throttle kicked....

It is never to late to search for more power. I had mine for 5K before I got caught up in the mod scene. I spent alot of time here reading posts, sifting through responses on various items out there and then formed a plan to get where I wanted to go. Doing things in moderation as the budget could afford I started with NST pulleys. I wanted to do things to compliment each other and solve little personal owner problems. Wanted better handling, solved that. Wanted a little more power/feel, solved that. Wanted to improve the appearance of some of what I call shortfall areas on the Yaris, did that. All done in stages and again as the budget could afford. Now, can I beat a modified any other car? Me? No, except maybe at the pump. But I like it and really that's all that counts. Am I done spending, looking, reading and or seeking advice in regards to power? No.

Came back to add that the Blitz is not a power addition. To me it's a feel type thing in that it makes you feel that you have more.
