DIY - 1.8L 1ZZ-FE TB Connector Chip Swap - Toyota Yaris Forums

ikenty · 04-03-2022, 01:39 AM

I know that I am late to the party but I just did mines.

2008 Toyota Vitz RS
JDM 1NZFE with Rocker Arms & EGR
Ported intake to match throttle body.
1ZZ Throttle body part no: 22030-0D031

I haven't done the chip swap as yet but I bought three throttle bodies to experiment so if needs be I will swap the chip using my spare 1nz throttle body and one of the other 1zz throttle bodies.

First start was 4500rpm dropping back down to 2000rpm so I drove it away so as not to wake the neighbors. After it got warm the idle was oscillating between 1000rpm and 2000rpm then it dropped to 800rpm idle.

After the first spirited drive about 50 kms the car idles at 800rpm. No CEL thus far.

I have a blitz throttle controller and the list of vehicles which it fits have 1nz, 1zz, 1az, 2az, 2zr, 3zr.

The 2zr and 3zr throttle are options for 1nz throttle upgrade aswell.
