Boost pressure values on Yaris 1.4L D4D 90

[rasyaya]

Hi everybody, :smile:
I have a 2009 Yaris with the 1NDTV turbo diesel engine (1.4L D4D 90hp).
I would like to have some information about boost pressure standard values.
A boost pressure vs rpm curve would be great, but even an info about the standard maximum boost pressure would be helpful.

P.S : the engine has a Variable Geometry Turbocharger, so no wastegate.

Thanks for your help :smile:

Bump

[why?]

Not sure anyone knows. PM CTScott, he might have an idea, or maybe an idea where you could acquire that info.

I have never seen a chart, but according to the service manual the max boost at 5100-5250 RPM should be 2.2 to 6.5 psi.

Thanks CTScott :w00t:
So that is a maximum boost up to 6.5 PSI above atmospheric pressure I suppose.
I have the service manual for the petrol Yaris 2. Where can I found/download the diesel service manual?

Correct. I will send you what I have for the diesel.

I also enjoy a diese 90 bhp. I am planning some mods to achieve better cooling and performance but I only have the petrol manual. Can you send me the diesel one, please?

1NDTV from 2009 boost peak 0.85bar and costant boost 0.7bar, to increase the boost you have to remap the ECU.
I remapped the Ecu and now I have boost peak 1.1bar and costant boost 0.9bar for 110hp ;)

hello CTScott can you send me those too?
