Seriously
Do you know what the power curve for the engine is? I certainly don't, but I would assume that Subaru chose 6k or 6.5k RPM (your provided information seems to vary on that) to provide optimum HP and therefore going over is not making you faster, but actually making you slower.
Please get yourself some automotive education, like reading some of the great many books out there or just about any of the amazing stickies on NASIOC, before you make another post. |

Another thing is I looked this up and people don't seem to think much of it, as if it's a subaru thing. What do you think? |

A few other things that are needed to confirm exactly what and why it's idling at ~500 would be the intake air temps and the engine temps. The ECM is not very complicated, but it makes complicated decisions based off it's preset map definitions and the logging it does of what's going on.
In short, the best way to help someone diagnose the issue would be to see a data log of when this occurs. The more detail the better. Also, there is nothing wrong with an engine idling at 500 RPM, as long as it's not erratic and the ECM can keep up with the changes that need to be made to maintain idle. I had my '09 2.5i idling at 575-650 until I sold my AccessPort. |

Okay, then you broke something in your car. You said you could rev to 6,5k in the first post. Then you said you could only rev to 6k, unless you shifted to L in which case you could spin at 6750... You're lying or you broke your car. Or enlighten me on another possibility if there is one...

650 RPM is perfectly fine for idle. Coolant temp is the temp I was looking for, measured at the hot side of the radiator IIRC. The engine may even idle a little lower if the IAT and coolant temps are a little lower. There is a heat compensation curve, too cold and idle will rise, too hot idle will raise. There is also a lower AFR in these conditions in an attempt to use the cooler fuel to lower the temp, or increased combustion to raise the temp.

The TCM is programmable, now is there a software out there that Subaru doesn't currently hide deep down inside their corporate loveliness, IDK...

If you had just disconnected your battery and the ECU/TCU was relearning, that would make sense to me. I guess we'd have to take a trip to Japan and ask the engineer what's up. I guess also that the fact that it's a CVT makes the programming even more of a mystery to me. Last edited by tibug; 10-01-2012 at 08:49 PM. |

With that said, it does seem strange that the "optimum" RPM would change. |

If you cared about acceleration over MPG's, you bought the wrong car.
If you really really cared about acceleration, performance, and bending the car to your will at HPDE, you also bought the wrong transmission. |

One other thing, my local gas station (holiday, top tier) sells their 87 oct for the same as their 89 since they're both e10 so I put some in for the hell of it... not gonna hurt anything, and I swear it's just slightly more torque-y in some situations, is this possible or placebo? I know some cars can adjust for slightly higher octane. TWO OTHER THING, what is "Timing Adv" in Torque (OBDII reading app for android)? It's from like -5 to 70 usually.

The difference in octane is most likely a placebo to u. Although every car can adjust for timing mostly either neutral or retard timing. If u get crappy gas and causes the car to knock then your ecu will retard the timing and make the car feel slower. Theoretically, if you constantly got crappy gas then the ecu will always retard the timing and the car will always feel slow and under power. This will then be come the "normal". And when given better gas the ecu will set the timing back to whatever it was programed at neutral. Making the car faster than what you would be used to. In this case, faster is relative or in relation to using ****ty gas and not an actually increase in power or more than 148 hp.
