  1. Hi team, I have a V3 STi I use as an autocross car. Engine is mostly stock, running the factory ECU and just a catless downpipe fitted. It goes great! I have an issue though that ever since I replaced the factory downpipe once she's warmed up and I give it the beans it hits boost cut every time. It has the factory boost gauge which goes up to 1.5cm3 and it boosts off the gauge by the time i'm at the top of 2nd gear. As a cheap solution I was thinking to just scale down the boost so it peaks just below the boost cut (around 23psi on a v3 i believe?). I have 2 questions: 1. Is this a common problem or do I perhaps have a fault somewhere? 2. Is a manual boost controller a good way to solve the problem? Other advice I had was to drill out the restrictor pill by a few microns at a time and then check again... I've drilled it out twice without any noticeable improvement, and I'm a bit reluctant to keep going as it doesn't seem to help. 3. For the first maybe 5-10 minutes of the engine running from cold, the ECU/boost controller seem to restrict the boost down to around the 1.2cm3 mark. It doesn't seem to be related to engine temperature. Can anyone tell me what this functionality is actually doing? I want to be able to avoid this on the track. I guess the best solution would be to replace the ECU and controller, but I don't have the dollars to do that at the moment. Any advice would be much appreciated!
  2. Hi team, im converting my previously daily driven v3 wrx sti to a dedicated autocross/sprint car. Engine is stock, i’ve just done exhaust and trying not to spend too much money on it. Problem I have on full track stuff is the speed cut at 180kmph. Anyone know a work around for this that doesn’t involve $2k for a Link ecu and tune? Sent from my iPhone using Tapatalk
