This is a discussion on New to WRX/Shift Points within the Transmission & AWD forums, part of the Tech & Modifying & General Repairs category; I wish there was a way for us to record our throttle position sensor's output and show a statistical sampling ...

    I wish there was a way for us to record our throttle position sensor's output and show a statistical sampling of it here, for comparison. I guess it would be good to know how much is city mileage, as well.

    I remain convinced that good EJ20/EJ25 mileage has more to do with how far down you're pushing the pedal, than with RPMs. In an engine with a decent-sized aftermarket turbo/bigger injectors/pump/tune, daily romps up and down freeway onramps or open roads after a turn, I still get 23-24mpg, even though I shift over 3000 rpms, almost 100% of the time. I'm easy on the throttle from stoplight to stoplight, because there's no point, and I cruise on the highway to work at about 68-69mph. I got high 20's when I was stock/near-stock.

    But then, I seem to be fairly good at wringing out good mileage, for some reason. Except with VQ engines. Not much I could do with that one.

    I think you hit the nail on the head here.


    For what it's worth, you can record throttle opening angle in a log.. I've done it before for a hand full of drives around town just for my own curiosity. Never really used to data for a real comparison though.

    If I'm trying to minimize fuel consumption there are two gauges I watch.. boost, to judge my accelerator position and "keep my foot out of it". And WBO2 to avoid open loop fueling. I'm convinced this is the main factor when considering RPM range. If you figure out all the circumstances that kick you in to open loop fueling and keep it around 13:1 - 14.7:1 at all times then you can't be using that much fuel.

    Thanks for the advice, guys! I was shocked at how low you can shift in these cars... The beast arrived just in time to drive it to work last night and I've been aiming for 2k-3k rpms. I havn't heard the turbo kick in yet. Unless my music's turned up too loud to hear the boost. :-/

    With a stock car, you probably won't hear much of the turbo. But you will feel it.

    you shouldnt be going WOT until its broken in anyways. 1000 miles wont take long. its worth the wait to know the motor was properly broken in

    Please stop creating multiple threads on a topic, and hijacking other thread with it too. I'm going to merge these all.
