dyno results

After having previous issues with my car and having the ecu replaced, I thought it felt like there was a bit less power with the new ecu/map.
So I got it dyno'd.

Here's the graph...



Anyone else dyno'd a 330S (or even an STi) to compare the results?
Or any comments if the graph looks normal for my car.

Cheers.

Re: dyno results

looks like you may be getting a boost spike around 3250 rpm,
the peak and then it pulls it and the graph climbs as you would expect ish,
Its certainly a little bumpy and seems to die at 5500 rpm.

Re: dyno results

the guy did read out all the figures during the run, but of course i can't remember them. I assumed I was getting a print out of the graphs & figures, but when i checked the folder of papers I got when I got home I only had one graph of bhp only
The graph in my first post was taken from my phone.

I've e-mailed them to ask if they can forward on the other graphs and let me know afr & boost.

The replacement ECU was supposed to correct an overboost situation, but it since feels like it's down on power.
Previously the acceleration was very aggressive right through the revs, but now it feels tamer.

Re: dyno results

the overboost correction will be to have dropped the boost target i bet.

have to wait and see what the graphs show

Re: dyno results

Finally managed to get another graph from hypertech.
Would this be expected results for a 330S ? I'm still concerned it feels like it is not as quick as it was, but I'm reluctant to get it remapped with all the stories of engine failure on these cars,
