    Factory Sensors and OEM ECU tuning

    in Impreza, Crosstrek and XV

    Posted

    Hi guys. Wanting to find out a bit more about what sensors our factory STIs come with off the bat. In particular for the new 2011 GVB models.

     

    Do they come with:

    Oil temperature

    Oil pressure

    Fuel pressure 

     

    From the googling I've been doing, there appears to be an oil pressure sensor under the alternator? If so, surely its wired into the ECU right? Otherwise what is its purpose?

     

    The end goal here is to be able to tune fail safes into the factory ECU without messing around with aftermarket gauges and control units etc. 

     

    Even if I can just get a fail safe for oil pressure into the factory ECU I'll be a happy man. 

     

    Anyone got any ideas? @Pappu1 @gotasuby

    After delving into this topic in much detail on my build. I'd recommend looking into the fin density before you buy a core. Ideally you'd want staggered or offset dense fins that will really disrupt and then cool the charge. ETS, Process west all have proven results and there's pics to prove the fin density. Others are a bit hit and miss imo. Some of the cheaper ones like HDI and even some of the cheaper Chinese stuff for sale here in nz seem to have good dense fins which could work well also. Personally don't think the mishimoto cores are great. And the Perrin ones look awesome but aren't as dense as the ets or process west ones. Despite being soooooo pricey. Havent managed to get a pic of the cobb core fins yet, but I'd take a wild guess and say similar to Perrin.

     

    Just stay away from the stuff that is basically straight through with no offset or staggered fins.

    I had 255kw and kinda got used to it. Albeit in the heavier GVB chassis. 

     

    Maybe think about water / meth? Got 20 extra kw on my setup with it. And probably cheaper than a full turbo setup :)

     

    Re the spool thing. Yeah its all personal preference, but there is some truth to what Boon is saying. Its all about building for where your powerband is going to be. I knowingly sacrificed maybe 1000rpm of spool on my build for a bigger turbo, but at the same time put in bigger cams and valve springs and gained 1000rpm of power band up high by being able to rev to 8k instead of 6.5k-7k. Assuming my stock turbo didn't run out of chuff by 6500rpm (which it definitely did before that point), I've simply moved my full powerband up a little and got a whole lot more usable power. 

     

    I thought long and hard about getting the smaller quicker spooling EFR7163. But end of the day, i'm only really sacrificing maybe 1000rpm of spool in 1st gear. After that its basically going to be an animal between changes (on paper anyway xD).

     

    All in all its hard to gauge anything like this until you actually drive and feel the response or lack of. My old setup was incredibly responsive and torquey down low. Will report back when this thing is going as a good comparison

    @Username just curious to know. What headers did you use to achieve this power level? Stock or aftermarket? @gotasuby appears to have got near the 400kw mark on OEM legacy headers which is dam impressive!

     

    I'm hoping to achieve 350kw off the single scroll OEM headers / upipe into a rotated setup on my v11. Pipe ID is 38mm from memory so hopefully will be the ideal mix of good air flow and velocity!
