I thought something was wrong with my car but it cant be because the re-flash shows it to be smoother. But in saying that, how can i tell as it starts at peak everything.

[QUOTE=Tony;724774]Had the re-flash done.

Just curious as to what you guys though of the graph. The original tune is kinda weird is it normal?

this graph..........................................................................................















makes no fucking sense!!

Sure it does Shane ... Everyone know that Ej motors idle at 2500 and develop peak torque immediately with no lag.

Never said by anyone ever.

This is a properly scaled graph.

Any tuner SHOULD provide all the above to anyone who just spent $X allowing them to play with your car.

Hey guys. Thanks to the people who showed interest in helping me out. Im locking the thread to prevent it damaging my relationship with Evo R. I was confused about the graph and thought it was normal, however abit of research and looking at graphs shows it not to be right.

Your factory tune looks about right for an 07. Subaru completely fucked up the tune on 07's which makes them jerky to drive. My 07 xt was the same before I had a reflash.

ImPreSiV 03-12-2012 06:00 PM

You're not locking anything... Neither am I. Tell me more about your relationship with Evo R. Were you asked to get your thread closed? Is someone holding a gun to your head... Wink twice if so...

Can someone tell me what the major controversy is? A dyno run is simply that; one run on a dyno.

The key points to take from your graph is that your power delivery is a lot smoother and your car now has a much beefier mid-range. It makes a bit more power at the top-end and the same at the limiter (the reason for this is your tiny turbo). You can't really tell how it spools compared to before as the operator has obviously pre-loaded or pre-spooled the turbo. If you're worried about how quickly your car spools, open your garage, start your car and go for a drive. (pro-tip: it spools fast because it's a 2.5L with a td04)

Seems like a winning tune to me, go out and enjoy it.

Sounds like a completely wrong dyno graph to me.

Unless the motor was replaced with an electric motor, you don't make maximum torque at the start of a dyno run.

Pro-tip: Every other dyno graph in the world of a EJ255/EJ257 with a TD04.

Like I said, ignore the effects of the pre-spooling and focus on the information that can be extacted. The first 1000rpms or so are garbage, anyone can see that.

No harm Tony. As mentioned, you will need that solenoid replaced as you can see the boost not holding.

AFRs are spot on there as you can see on the power run.

If you don't already have a Walbro fuel pump, get one. Also a Process West Top mount will be the way to go.
