Had the GT4 mapped today Options

[mmorg3053]

Had my Apexi Power FC fitted and mapped today. It is running at 1.2bar of boost and holds all the way to the redline. The figures at the FLYWHEEL with an estimated 25% transmission loss are as follows:
332.1bhp@6441rpm
317.7lb/ft Torque @3961rpm
Power at the hubs was:
249.1bhp @ 6441rpm
238.3lb/ft @ 3961rpm

Wow...that's awesome! Congrats on those numbers!

What mods do you have planned for the future?

[mmorg3053]

In the long run im going to have a full forged engine rebuild and a lovely turbo. Going to keep it as it is for the time being (see my profile).

Thats sick!!!!

[lagos]

hahaha coomer, you crack me up sometimes. the guy posts about getting his celica to the 300hp level, and you expect him to do more!! hahaha

[Mr_E]

Good stuff.

What you using for an ECU?

I need mine remapped soon. It's on the list. 310bhp - 290lb/ft will be fine.

[macavely]

i hate you GT-4 people .. i really don't.. i want to be one of ya'll..


Nice.. so what you going to do next?

[Magic]

mmorg3053 Very nice VERY VERY NICE!!!!

BTW who mapped your ECU??Which performance shop??

[mmorg3053]

Thor Racing near Coventry. www.thor-racing.co.uk mate.

[Magic]

Nice nice...The guy seems to know what he is doing...this is good Here in Cyprus they "learning" on your car...
You running on Standard Fuel Pump??You dont use Fuel Pressure Regulator??


Thank you for the information dude.

[mmorg3053]

Standard fuel pump at the moment mate. No fuel pressure regulator. Standard injectors.
All these will be updated in the near future. I only get paid once a month you see. ha ha.
Obviously I need to start thinking about pistons, HKS head gasket etc...

May I have a look at your dyno graph??

[mmorg3053]

As soon as I get a way to upload it I will post it on the forum mate.

THANX....

[mmorg3053]

Dyno graph
Click to see the dyno graph on the GT4OC forum. The graph is half way down the page. The figures on the graph are at the hubs.

[mmorg3053]

Lar, can you send me your email address please. I will send you the graphs.

[Magic]

mmorg3053
This is very good dude....line its much smoother after the tuning of the PowerFc.
And you are running on a CT20b right??
And 317.7lb/ft Torque @3961rpm its also impressive !!!


Great

Do you have any accounts with Evos?? Its time to solve them out!!!

[Mr_E]

Nasty dip in the middle of the torque curve mate. Any idea what causes it?

[mmorg3053]

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.

[mmorg3053]

Other graphs are now in my profile.

[Lar-]

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

[Lar-]

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.... .

[mmorg3053]

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.
