turbocharging a yaris...a theoretical question
I have read a few turbo-ing a car guides, saw a few youtube videos and all share the same thing. they all say you should get some kinda new aftermarket ECU, since the air entering will be different and the engine will run lean.
My question is, cant the MAF sensor detect the change in air flow? Cant the stock ECU adjust the fuel injected accordingly? |

It does not have enough range to cover boost. They map the engine to handle all intended conditions. They are not going to waste time developing tunes to handle boost for a handful of enthusiasts

That being said...my tercel handled 3.5lbs of boost perfectly with no tuning.

so an aftermarket ECU is a must?
does the Blitz Supercharger come with an ECU? I have read that it makes about 7psi of boost.

You need a return style fuel system and a 1:1 fuel pressure regulator. That will help you a lot when the boost comes on.

so I downloaded the online install guide and the thing has about 40 components and there is no ECU....the only electrical thing I can see is a relay, some harnesses and connectors. if that thing is adding 7PSI with out any chip tuning, wouldn't it be possible to achieve this with a turbo for a far less price?

Unless I'm wrong, someone can correct me. Personally, I wouldn't boost mine unless I built up an engine for it. With the amount to invest in a good Turbo, mind as well go all the way and do it right. My 2cents |
