Default What do you think of this dyno sheet?

A bit low eh? My car is a JDM 2.0L sti, with zerosport downpipe, midpipe, hks exhaust and intake and aquamist 2d with 50/50 methanol/water mix. Dyno is a dyno dynamics dyno which is famous for giving low reading, but wasn't expecting this low. ECU is a autronic SM4 plug&play. Tuner is my own uncle who is a local drag race champion on his 450whp GC8.
What do you guys think? Just so you know, a stock jdm sti on the same dyno only reads 206whp.

Boost at 1.3bar tapering off to 1.1bar towards the end:



And here's the air fuel ratio:

Looks like a pretty bumpy power curve. Something is not right.

edit - your air fuel ratios bounce a around a bit... smooth that out and re-tune the timing a bit and you'll end up with smoother power.

My initial reaction is that with the 50/50 alcohol, you could lean it out a little bit just about everywhere too.

Email me your autronic map and I'll take a look as well. Post some datalogs too so we can see what kind of timing numbers are being used.

What boost controller are you using? AVCR?
What fuel was it? Pertamax Plus?

I already got your result from your uncle.

In short not good. The main drawback is that you do not have the AVCS system working. Notice the huge loss in the low end as a result. THe AFR looks fairly smooth from the log. The boost looks smooth. But its falling off badly. I have to suggest that the up and down in the power curve is probably due to the timing curve. It looks like your uncle has a good start. But it needs some smoothing.
