Hello Everyone,

Really like my 2004 Yaris 1.4 d4d. Normally trying to up the power on diesels involves chipping or remapping.

But Toyota seems to have done it for us, or am I wrong!

The 1.4 d4d in mk2 and later Yaris have an extra 15bhp, without any obvious mods.

Was it done by a different chip or is there other mods which are not obvious?

Is it easy to up the power to be the same as the later versions?

Thanks for your help

Graham

Chipping is easiest. I did it .. more power and fuel consumption the same.. But some black smoke suggested overfueling.

Mine is now standard as I removed the chip.. Which I think I still have...

As long as the chip power settings are not too high, you shouldn't have any smoking issues.
