What turbo you have on the STI.

 

This dyno reading was not converted to SAE corrected figure.

My dynojet number went from 337 to 329whp when converted form STD to SAE corrected figure...

Good number though...

 

When I take it to LACR I'll find out what it really has. This graph is just numbers that I'm proud of. But the car will get its test on the track. Dan tuned my 03 WRX on the same dyno and it put out 272 WHP and around 230 Torque. And I ran that car 12.6 @ 106mph w 1.702 60 foot at LACR. So I expect low 12s with the Evo. But I will need a better clutch first.

 

now i know around what hp i am going to be running when i finish my first mods to my evo 9. thanks.

 

still waiting on the rpm awnser.....thanks in advance

 

VF39 ---- stock turbo for the STi

Also, the 340 on the Evo was uncorrected. The correction factor for that dynojet was 1.04= 354 whp. It was done when the temp was 93 degrees

 

Sorry but I don’t know your answer. I hope someone knows and will share it with us.

The software takes the dyno and tries to make the line smoother.
It turns it into a more "best fit" line than an actual point-plotting line.
The lower the smoothing factor, the more accurate representation you are seeing.

If you go lower, you can see possible issues like wastegate solenoid flutter or other things that you won't see with heavy smoothing.

Also, good solid tunes should be on low smoothing...On high smoothing, everything looks nice and curvy.

 

There is no answer, because you didn't ask a question that made any sense.

Guys, why are you all asking questios that can be answered by looking at the graph?

1) You can see the boost was around 25psi (24 if you say so, but it looks like 25 and is still at 25 about 1500rpm after the spike, which I consider dangerous on 91oct)

2) You can see the AFR curve, too, but the tick marks are so close together that you can't get any specific details, plus there are no lines crossing the page to denote where the tick marks reside

3) Of course this is the stock ECU. Why did that one guy say it wasn't?

4) Are people just not paying attention over the past year? These are the numbers we EXPECT on IXs with these mods. A IX with a custom flash and these mods can make 350-360whp on 93oct, and this is really good power on 91oct, although the high boost scares me.

5) STD and SAE don't always have the same correlation. Again, the graph shows a 1.02 STD correction, so the true numbers are 326whp/318wtq - still not bad. SAE could show higher OR lower - it just depends. The conditions on this run were 80*, which really doesn't require the 1.02 correction.

6) $500 for a custom tune + dyno time is not bad at all. This also tells me that Harman is no longer using EcuTek on IXs.

7) Read my sig. I've had it there since the beginning of the year and guess what...it says 330whp for stg1, which is the same mods except without the LICP and with only a base flash. This is exactly what all IX owners should expect.

8) Smoothing 5 is normal. That rounds the jagged edges that are so common on a Dynojet. Doing low smoothing does NOT mean it's more accurate. Quite the opposite most of the time. A plot with 0 smoothing looks like sawteeth, which also gives unnatural peaks and valleys - this always gives a higher peak WHP that isn't necessarily real. Notice the curve on a DD or Mustang - it's even smoother than Smoothing level 5 on a Dynojet.

 

Thank you for the explanation.

 

Ok. Went to the track tonight. And I have an interesting issue. When there are cars reving next to my car my idle gets screwed up. What do you guys think this is from. Also when I go to LACR my vacuum gets screwed up. Instead of -20PSI I have -15PSI. Can someone please tell me what is up with my car? And I did run 12.8 at 105mph. Do you guys think I have vacuum leak or another problem.

You really should invest in a Tactrix OBDII cable and logging software. You want to make sure your car is not knocking when raced or on the street after any tune, especially one that was performed on a DynoJet (if they did not employ the eddy current load option). IF they tuned on the dyno without loading the car properly, your tune could end up leaner on the street/track than during the dyno pulls. By the looks of the graph (hard to tell with the axis scaling), you were perhaps at 11.5:1 on the dyno. It is possible that you could now be running much leaner than intended by the tuner, getting some knock, and the ECU is pulling timing during the runs. Just a guess given all that you are reporting.

With the very minor investment in a cable and logging software, you'll KNOW if all is well after some tuner SAYS all is well. A logger, cable, and a supported wideband sensor system are essential for any Evo owner trying to mod the car with a stock ECU.

Your MPH (105) clearly shows you are down on power from what the dyno reported, and something is definitely amiss. I guess you could have a boost leak or some other mechanical problem than the tune, but you should have logging ability to ensure your tune is all good on the street and track.

 

Do you know where I can get the hardware you are talking about. I am very interested in getting it. Please let me know.

Are you talking about when the car is REALLY loud and bassy? Like muscle with open headers ? I've had this happen to me while at a light with a harley next to me... read somewhere that it messes up the maf signal.... don't quote me. Try searching

 

LOL, thats the higher elevation of LACR that is showing a lower idle vacuum. I always read about 3 inches of vacuum less up there than at near sea level where I live. You also have to adjust your boost level to compensate for the higher elevation. I always read 2-3 PSI lower and taper to a lower level when I'm up there. As for the idle issues you are having. I have that happen all the time with my 03. I was told that the 03's have a sensitive knock sensor and will trigger to certain frequencies of loud open header V-8's, Harleys, ect.. I thought the newer Evo's especially the 06's didn't have that problem. I guess that your knock sensor is sensitive also.

I'll be going up to LACR next Friday evening let me know If you'll be there. I'd like to see you car run. I'm hoping to hook up better this time around. I was trying out the launch control that Tuning Technologies had put in my ECU and was spinning badly out of the hole. Hope the track is better prepped this time around.
