This is a brand new product that we are introducing, from Vaus / SubieShack, with the discussion thread over
The Open Loop Manager 2, or OLM-2 for short, is the incredible new device for the WRX. This little device is tapped into +5v, ground, MAP, and TPS signals. It watches the MAP signal and once it sees a certain MAP value (boost), it simulates a WOT signal for the ECU. This does two things:
1) It immediately forces the ECU into open loop fueling.
2) If stock boost control is still being used, it makes the ECU shoot for full boost no matter what the actual TPS value is.
: For those who have not heard of the PTFB issue, read on. The stock ECU limits boost to ~7psi until you go past 63% throttle (TPS). It also stays in closed loop fueling (stoich a/f of 14.7:1) during this 7psi. When installing an MBC, you will be able to boost a lot more than 7psi at lower throttle positions. The problem is that during this situation, the ECU does not switch to open loop fueling (rich) no matter how much boost you are running as long as you are under 63% throttle. Doing this for an extended period of time causes high EGTs, detonation, and engine damage.
