DIY - 1.8L 1ZZ-FE TB Connector Chip Swap

[yarstar]

Just like Gideon, I even like the high rev cold idle. My car sounds like it has a turbine engine when it fires up. The idle goes down once the cold light goes off. High idle only for about a minute.

Before the yaris , I owned nothing but beastly dsm's and mk3 turbos so i'm use to loud cars with rough idle . Imo the yaris was wayyyyy to quite when I first got it . I'm sporting aem w/fujita filter , megan header, nitto mid, hks axle back , nst 10% ud pulley running on 91 and i'm very surprised at how "peppy" this little 1.5 yaris has become . Modds planned are the Tb swap , coolent bypass , tb spacer (for S's and G's and I'm gonna do before and after dyno test for proof good/bad) and my friend is starting on a 1-off long tube header for me(similar to Richard's design)
