While on the dyno the MAF sensor maxed out so it started to dump fuel. From 6,500 up the AFR's went from 11.0 to 10.0...

We would like to think there's more power left in the same tune, but until we make a bigger intake for the car we can't find out...

The signal cable was having some issues also so the trq didn't start to read right until 54mph...i just connected the low points just for reference

pass the dutchie to da left hand side

that power drop is pretty bad.

any boost or AFR plots?

And you can get around the maxed MAF going rich by leaning it out.......i mean if you're running 10.9 before that......take it out to 11.3-11.5 and then you'll only drop to 10.5 at redline.

I passed it but you weren't there...

The drop off towards redline is real bad, and sorry there no boost or afr plots...the drop-off is directly related the MAF maxing out and the ecu dumping fuel...

We can lean it out but don't forget one thing in Jamaica the highest Octane fuel is 90 Oct, we call it "piss water"...but it's what we have to work with...

Thanks for posting up the figures and the vid Ducash. Yeah, the fall off in power up top is due to the MAF maxing out and the ECU flooding the engine with fuel. Since then, my tuner has scaled the MAF and it hasn't been maxing out on the street, so I intend to put it back on the dyno to see what the curve is really like up top as well as to get a clean torque curve.

360-370 lb/ft of torque is about what you would expect from a Dom 3 at 26 psi on a EJ207.

hey ducash i found a way to get the rpm read out on the dyno chart. i did a little calculation and found that in 4th gear every 13.333 mph gives us 1000rpm. so i started from 40mph which is 3000rpm and just did my maths from there. so with a little fine tuning on microsoft paint, i got us an rpm readout. voila!!!



we have atleast another 50whp to get after 7000rpm when we get the MAF CEL fix, maybe even 500whp on the fully stock motor and 32psi, what do you say garfield??

As long as it's on race gas I'm cool with that . For now, I'm happy with my 447 whp .

just out of curiousity, what kind of headers are you running on this car?

JDM twinscroll headers to a Dom 3? did you have a special 2-1 uppipe also 1.5 scroll fabricated?

Thanks. Swiffy (my tuner) has done some fantastic things with Subarus here in Jamaica. Here is a link to some of his work on our local Subaru Owners Club website:

I thought maxing out the MAF meant a lean condition as the ECU can't meter the excess air?

^^ interesting. i never really thought about that....

But my HTA Green'd WRX max'd out the MAF and i went wayyyy rich too....down to 9.5:1 with 11.5:1 targets.....

But both this car and my car are running meth.....maybe that has something to do with it

Prior to putting the car on the dyno, I had no idea what effect maxing out the MAF would have on the car. But while the car was on the dyno, I watched my wideband (I'm the bald-headed person in the vid), and as soon as the CEL came on the ratios went from 11.1 -11.2 to 9's.

I don't disbeleive it, it's just the opposite of how I thought it would be. I.e. if it maxes at 400g/s and it's really getting 420,430 etc then the ECU won't know how much additional fuel to inject, causing it to go lean.

well, if the CEL came on and you went into limp mode....then you switched to the failsafe fueling map.....which is very rich, unless you changed it.

When the ecu "realizes" it doesn't know what is going on, it plays it safe and dumps fuel... normal response.

Because we get mostly JDM cars here, there's more 2.0L STi's than 2.5L...We've got a couple more cars that should have some good results...so there's more to come...

There's someone here who has custom made a 2-1 uppipe so they could keep the twin-scroll headers...

Every JDM Sti since 04' comes with the twin-scroll set-up, i got 360+ wft/lbs by 4,500rpm on a 2.0L with the stock set-up...

Thats why we think there's more left in this 26psi tune...

I see your running a VF37, I had a VF36... I miss that turbo.

I should have my 207 back up and running soon. Looking to do better than before... we'll see I guess.
