Yo YW people!

These last 2 weeks my car has been in for development, and except for the extra gains and smoothing out my power curve ect. these guys has asked my if I want to chip it... Now I could gain 3 to 4 Kw more, its not a piggy back and I can set everything there is to set on my Yari, especially for future upgrades,

Now, do you guys think it is worth it or not, I mean if I ever want to Turbo the car, it will be so easy as I can just set everything I need to....

Let me know what you guys think...:iono:

What does "in for development" mean? What "extra gains" and what does "smoothing out my power curve" and how did they do that?

No idea what "chipping" it means. Usually that means modifying the stock ECU in some way, but...? :iono:

Can you be more specific about what that is? Show pictures? Another car done the same way? That would be helpful.

I know that is a lot of questions, but I don't understand the post, sorry!

I am sorry bout that,

Maybe bcause i am South African...
Dutchman... LOL

Ok, lets Start,

Basicly my car has been in development for a proper, fine tuned race exhaust, not something that just sounds nice or something you slap on and can buy in a shop, it is a full exhaust system with custom Pipes and also the Header(Banana Branch) that has been built piece by piec and using a Dyno to see what the diffrance has been, now the exhaust is nearly complete and I will Post Pics and Charts ASAP, the Gains so far has not been much but it is there, the power curve on the Dyno chart was very unstable, zig zaging basicly and that means the power deliverance and drive ability is reduces so I was unabe to propely reach the torque and power properly... now this has been fixed and improved greatly to a smooth line and power gain...

I went to see my car on the week end and they demonstrated and I was greatly Surprised what diffrance it has made, and they are sugesting that I "Chip" the car, it is basicly a direct ad on for the Bosh ECU so you can tap in and change everyhting the ECU controlls, they said I can get around 3 to 4 maybe more KiloWatt more out of the car and also smooth out my power curve a lot more adding response time and effeciency.

I want to know if it will be worth it, it does not cost much at all aprox $200, what I want to know is it worth it? I am sure it will be usefull for future upgrades...

“they said I can get around 3 to 4 maybe more KiloWatt”

Just thinking about selling that back to the power grid and the cash we could make. I wonder how many hours per gallon we would get?

3 to 4 kilowatts = 4 to 5.36 horsepower

They can't. The OP is just an idiot being washed for money, but can't see it.

The new exhaust will open up the flow a bit more, 4-5hp sounds about right if he's going with (assuming) 2 to 2.25" piping.

They can't crack the ECU because Toyota locked it. Ask ANYONE who's turbo'ed their Yaris how well they've come along with the remapping of the ECU.

N3misiS

05-25-2009, 02:01 PM

No Faith Guys,

I called around today and there have been more Yarisis Chippep,
What I am going to do is proof this, the only thing is Cash, I dont know how but I will get the proof, I gace the company name...

More Faith, if we can get the ECU cracked, hell why not, I have been in contact with a few guys willing to do it, it should take 3 days on the dyno....

Like I said, if there is enough support I will do it!!

Deltasix

05-25-2009, 02:12 PM

I'd be impressed if you could show me an actual proof of the claims that are being made to you/ you're making to us.

N3misiS

05-25-2009, 02:16 PM

I agree with yhou guys, but so far this specific company has not failed, we have done Honda, Audi, BMW, you name it....

As soon as I have the cash and time I will do it!

As soon as they told me about this I actually though, let see maybe you guys
can benifit too...

Deltasix

05-25-2009, 02:33 PM

Well, they should be able to show you some proof (preferably independent proof) that their stuff works before you pay the money to get it done to your car.

N3misiS

05-25-2009, 02:37 PM

No Question there bro, this weekend I am going to go have a look! I just got of the phone with them, they have pics and Dyno charts too! If I can get my habds on them Ill post them here ASAP.

TheRealEnth

05-25-2009, 02:38 PM

yeah go for it, see if they can actually do it... seems possible tho .... cause they are saying you will gain about 4hp... rather than a ridiculous amount like "HEY LET US CHIP YOUR YARIS YOU WILL GET +30hp and" so maybe they are on to something... Do it and tell us what happens? woudl be best if u dyno'd it urself before chip then after u do it u dyno urself again

firemachine69

05-25-2009, 02:38 PM

It takes more than just a dyno to crack the ECU. You ARE out to lunch, aren't you?

Your new full flow exhaust will give you gains. I can assure you they are not capable of cracking the ECU. Why? Because it would involve alot of time, money, or stolen property from Toyota. They'd never get back the money they'd put in.

Hell we have some Yaris EXPERTS on here who still haven't been able to get it cracked. It was simply cheaper to get an e-Manage and go from there (a device which costs $3k+).

We have a few YW hopefuls just so desperate to hear of the ECU being cracked, they'll believe it without any doubt when any schmuck in a garage says he can do it.

TheRealEnth

05-25-2009, 02:41 PM

its not that hard to crack an ecu... just any person who actually has the ability to do it sees no purpose in our little economobile, no profit either... He would do it and probaly only 10 people would buy... every1 else would be like "Oh i gotta wait and see" "thats unsafe" "Oh Gee Willigers 100$ is too much for me"

N3misiS

05-25-2009, 02:46 PM

I understand, I have been watching that subject, but it is not out of the ordenary,
but still I will have to get the proof, pigy back's are an option but not one for me, there are to many things that can go wrong...

Ive seen so may things already, but I will try and live up to it! maybe by wednessday I can have proof, I am going to get my car and then see if I can get more Info>>>

You guys need to come to SA to see wat we will do for half an hp...

firemachine69

05-25-2009, 02:48 PM

So what do you call the folks that dumped about 5K under their hoods for a custom turbo setup, and would rather crack the ECU that get a new stand-alone?

The current Toyota ECUs are LOCKED. Full-stop. They are not accessible, and so far as I know, still read-only. Which is part of the problem. They're innaccessible via standard means, and no ones figured out how to make them read/write devices. This applies to ALL current Toyotas, not just the Yaris.

N3misiS

05-25-2009, 02:50 PM

MMMM... That means we can definitly crack it... we have done the Fortuner, Auris, pevious corola...

05-25-2009, 02:51 PM

i don't put much faith into chipping the yaris, especially because what magical gains are you expecting to receive from a computer upgrade, a few hp/kw tops? i wouldn't test it, personally

TheRealEnth

05-25-2009, 02:52 PM

oh right right cause toyotas got the chips on lock hardcore.... even more than the actual Nissan GT-R ? Dam they are serious about their shit

N3misiS

05-25-2009, 02:54 PM

You guys are makin me want to spend the money so we can see how it works!

Hell Yeah, and I have a money back Gaurentee, why the not... will place my order now...

N3misiS

05-25-2009, 02:57 PM

Well look, I am nog going to get Cocky, lets just see what happens,

And Electronics controll a great Part of any modern car, if you cant touch the ECU you cant turbo with much effects...

05-25-2009, 03:00 PM

still sounds like your yaris engine will become a test bed for their chipping...they've never done a yaris before?

Yes, 1nZ.

Not mine specific as yet as it is the smaller one...

N3misiS

05-25-2009, 03:14 PM

It is under testing... I dont know.

Lets see if I can get results first, they said it wil be no problem at all....

firebob

05-25-2009, 03:17 PM

Ok lets just say that they did “chip” his ECU. As soon as the ECU losses power it will go back to the factory setting. The chips that hold the current settings need to be powered to hold there memory. When the ECU starts up and it can not find current settings it goes back to the factory settings that can not be changed by the design of the chips.

N3misiS

05-25-2009, 03:20 PM

That is very clever actually and sucks, but then I supose they will use a rom of some kind to store it, I dont know... but it is posible...

Kioshi

05-25-2009, 03:44 PM

Guys instead of arguing bluntly, let N3misiS be the guinea pig and try it. We are lucky to have people go try out things for us outside the states and not have our money wasted on something that will/will not work.

Some will be right and some will be wrong. Thats just the way it goes~

Give us the info when your car comes out "chipped" N3misiS :)

N3misiS

05-25-2009, 04:00 PM

THanks Kioshi, and what you say is true, when the guys asked me do I want I chip, I imediatly thought of You guys, just Maybe I can get something done about it...

I am not new when it comes to tuning a car, and the guys here do have the correct arguments... but its wide, and I want to close the gap...

A hell of a lot of info I have gotten from here and tanks to YW!!!

Ill do my best.

If there is one thing i know about technology is that it always advances. So What was once impossible has now become childs play for a 3 year old. Hackers have hacked the most impregnable systems...so i think they might be able to do it. There are alot of smart people out there.

You guys still don't get it.

To "read" the code, you need to have the native language and assembly environment. So unless someone's stolen this from Toyota, the data on the ROM is useless.

FYI, you cannot add new data to a simple ROM. EPROM? Yep. ROM? Nope.

Good News Guys,

We can chip the Yaris, expect a 12 to 13 percent performance increase, as soon as I can get the cash I will do so, if you guys want more info or proof contact Unichip, they
have already chipped a few here in SA.

I wouldn't expect anymore than 10hp to the wheels with no mods...and that's pushing it. Sniper Tune here in florida had unlocked the ECU for the miata(NC) and gained 10hp with no mods and that's on a 2.0 engine.

I bought the cheap thing from eBay, then opened it up to find a single resistor.

My understanding from the post above is that we are not talking about unlocking the ECU, we're talking about a piggyback like the UniChip.

If this person is talking about a UniChip tuned for the Yaris, that has some possibility. However, at least here in LA (which is pretty big), there are no UniChip tuners. My impression is that UniChip is much more popular overseas for tuning.

So, this option would have to come already tuned with a plug 'n play harness for the Yaris. The UniChip, while not cheap, would probably be worth it if it can provide 15%+ power gains as quoted.

N3misiS

06-03-2009, 08:46 AM

Hi Guys, Cali, you are corredct again...

Unichip is extemly popular over here and there is a plug and play harness, it is like a piggy back but there are more options, you can play with timing ignition and vvti and the usual but you can have a wasted spark unit as well, change cams, and keep the performance upgrade!!!!!

And then for the boosted Yaris owners it should be good news, it is not that expensive and the gains and power over your settings is definitily worth it...

hey can anyone replicate sprint booster or blitz controller.. for maybe 1/4 of the cost.

markitect

hey can anyone replicate sprint booster or blitz controller.. for maybe 1/4 of the cost.

I've been thinking about this:

The accelerator position sensor just has two output voltages.
So my guess is the Blitz/sprint controller is just a simple microcontroller with two analog inputs and two analog outputs, or even simply a rom with a table mapping the input to output and the switch changes an address base. There Might be RMS converters too.

Takes the voltages in, puts them into an equation and outputs the result on the outputs. Add a couple GPIO for the reverse sensing and mode switching, and something for the display.

That said you could use an oscilloscope to see the factory signal as the pedal moves, then come up with a desired signal over the range. Then find a mapping between the two.

You could then get an appropriate microcontroller and build your own.
Possibly design a analog circuit that will perform exactly one mapping.
Or have a rom with a lookup table with the analog inputs addressing it and the value in each address corresponds to the output at that input voltage.(This seem easiest, but someone that programs PIC microcontrollers will probably opt for number 1)

I was messing around with doing something similar for my Mazda. I'd started on one design based on a signal ADC/DAC when I found out there were two APS signals and that they had to correlate. If anybody knows of a good cheap microcontroller with a built in two-channel 5V ADC and DAC maybe I'd get it started back up.

My plan was to hold the table in EEPROM and make it configurable over the serial port.

I use PIC microcontrollers for everything - They're cheap and there are many options for I/O configurations (analog and digital). The DSPIC series have DACs, but I would actually go with a non-DSP one and use I2C DACs like the Microchip TC1321, that way you can chain as many as you need (up to 255 of them). I would really like to have a spare Yaris to experiment with (a wrecked one with a running engine would be fine).

The dev kit is under $100

someone should scope the signal to confirm its really a DC signal though, wish I had some more free time.

Hmm, that micro doesn't look too bad. I'll see if I can get a sample.

I know that on my Mazda I was able to pull APS voltage from the OBD-II PIDS, and it was a 0-5V DC signal. I'll see if I can hook my laptop up to the Yaris this weekend and confirm that it works that same. By the way, you really don't need a whole engine to test this, just the accelerator pedal.

The only bad thing about that 8051 based mcu is the amount of support circuitry required. The PICs require far less.

The reason I would like to have a running engine to bench test with, is that I see taking this to the extreme of actually using the microcontroller to even fire the injectors. The injectors are controlled by a PWM signal. For Turbo and SC cars the system could then meter more fuel as required (by tweaking the PWM duty cycle).
