Newbie with Q's, reliable WHP - Toyota Yaris Forums

mickymouse · 12-26-2008, 09:57 PM

thanks for all the replies so far.

I looked through the pictures of the dynos. However did not find any before - after from one person with the bold-ons. Just when FI.
So, when you talk about xxWHP, is there any one with a documented performance history? I know this one guy who pulls 120whp from Arizona, but I did not find information on the engine?

@ztrack157
thanks.
When you say that there is a rev limiter but it is no problem, what do you mean by that?
Does it mean the Yaris revs freely into the limiter without having a smooth cut off?
Every modern car I have driven in the last 2 years show a similar behavoir... too much electronic influence and a smooth power reduction starting about 800-500RPM before redline.... and the revs are kept about in the middle of the redline.
Older cars reved into the limiter quite hard - harsh (this is what I am looking for).
However I have not had a chance to kick the Yaris, did only a short test drive on the parking lot (here in China they think that is enough)

you wrote that there is a throttle body upgrade. Are you refering to the same one as Zefoxe, swapping the stock 1.6 with a stock 1.8? Or are there any aftermarket ones available?

Do those units replace the ECU, or is this like a drop in emulator with real time adjustment capability?

Thanks. Sorry for all these questions. But since I am an egnineer I like to educate myself before I do things. And I want to do them right. Thus I prefer a one time install, best if the individual components would be proven to work together. I am hard pressed however to find reliable and informative sources. Heck I would even import a complete system from the US or Japan (does not know where to find it). The only thing I found was some FI and CAI, Header... but all those things seem to be thrown together without a close attention to the details....?

Well, anyhow, thanks
Mike
