Had the GT4 mapped today Options

Magic, yes I am running the standard turbo.
Mr E, Im not too sure about the torque curve. Doesnt torque always hit its max in the mid range and then drop? Could be fuelling. A friend is going to post up the other graphs soon on the GT4OC.

Hi mmorg3053....

Is your hp graph complete??

And, what does the Red line represent??

[mmorg3053]

Red is the first run when the boost controller wasnt set up right, and the Apexi SAFC was overfuelling like mad.
Yellow is the 2nd run with the boost controller sorted but the SAFC still overfuelling.
Blue is with the SAFC removed and the Power FC fitted and mapped with the boost holding at 1.2.

What do you think Lar? Does it look ok to you mate? Cheers

I see...

Honestly, I think you should remapped your Power FC again.
11.0 AFR is a little rich. You still have some horses sleeping around in your engine.

Go a little AFR leaner than this.... somewhere around 12 - 12.5.
Also, ask your tuner to do something about the glitch on both the Torque and Hp curve between 4000RPM to 5000RPM range.

Your boost curve is fine.... .

Cheers mate. I will have words about mapping out that dip.. I think that the AFR was as lean as they wanted to take it so I didnt get detonation. Bear in mind that the engine internals are standard, I think the current AFR is safe for the time being.

Have you got any graphs I can look at please?
Thanks
Mike

I still don't have the time to take my car for dyno run yet... . The dyno place is quite far away. I will have to take a whole day off work to do it.

When I get the chance to do the dyno run, I will let you see my dyno sheets for sure.
