Ok, this is probably more aimed at Scott, but feel free to chip in,

Had a problem with my knock sensor recently which I think is now fixed, so did some logging in RomRaider yesterday on a trip to Jap Performance.

Knock sensor seems to be running fine. I did reset ecu before I went and then once engine up to temp did some gradualy harder third and forth gear pulls made sure everything looked ok.

Then did a few 2000 to 6500rpm 3rd gear runs in anger.

I have noticed that towards 5500 upwards I am running a 90 to 97.5% injector duty cycle. Isn't around 90 - 93 % considered max?

Is it worth getting an adjustable fuel pressure regulator and upping the pressure a bit and then fine tuning the map?

I got some feedback knock correction around these rpm's on a couple of pulls of about -2.11 but no fine learning correction. This I believe to be ok?

Also my boost is only going to about 1.14 at moment, I thought it was set to 1.2 so I guess this is about right, this is something I am looking into possibly increasing slightly.

exhaust gas temps are up to 650 degrees C. so are these ok?

using airflow readings of 267 g/s is it possible to estimate bhp?
