I might try to swap with stock to see what that sounds like but will probably stick with the Q

I heard the stock exhaust may cause rasp with a catless header so you will probably stay with the q.

It doesn't though.

Oh yeah? Cool beans. Are you running a catless header with the stock exhaust?

Yeap, just ofh and stock everything else.

I wonder if the rasp is from people removing the second cat then. I have heard a few videos and it wasn't the greatest sound.

Rob was kind enough to send some cabling etc. (To speed up RHD kit development.)

So bought some batteries and here is the result.

Almost done with the WOT bracket development.

Away until 17th so will have another update late next week.

@shiv@vishnu can you confirm something for me?

The 'manifold pressure' in the OFT logging, does it account for atmospheric pressure in its calculation of boost?

Is there a absolute manifold pressure that can be logged?

Reason i say is my car feels faster than ever but the boost does not correspond with what we would typically see in Calgary

You can log manifold and atmospheric separately.

Geez,


I didn't know the datalogger did manifold pressure.
I went and bought a pressure gauge. At least I got it at Harbour Freight so it was cheap.
My datalog manifold pressure peaks at 4.45. Not bad for a "battery powered toy."

I'm checking mine at lunch. I don't think it considers atmospheric pressure. Will report back soon.

Interesting. On mine it caps around 3.8 psi through the torque app.

Hey guys. If you are watching manifold pressure on the oft you have to add the atmospheric pressure to get your true boost. With my car off the oft reads -1.93 boost so I have to add 1.93 to get the actual boost being created

This is correct.

Here in the SF bay, my atmospheric pressure is 0.24psi

Oh wow you are LUCKY.

So is there a way to monitor the corrected value or just have to monitor absolute manifold pressure and subtract?

Thanks!
