Callin' 4G61T Owner - Wanna Up boost @ 0.8

[kk9972]

Hi Khoyos,
Thanks for the advice. =)
Previously was 1.2bar with no overboosting sign. Means no problem adi (mayb...) So. 0.8 bar should be no problem right?
em.. I will try it out.

Hi Ken,
Haha, I don't wish to be monster. smooth drive, smooth acceleration will do. Especially bypassing the front car.

Yeah, how is your fuel consumption? Mine is very very bad i presume. Off boost with vacuum driving only will cost me RM50 = 120km only. It was running 42psi running engine fuel pressure. :confused_smile:

After searching all over, i decided to do a test. I follow the specification of the stock standard engine and start troubleshooting. Hope i am doing the right thing.
Now running on 35psi engine running. :X-:

Hi Ken,
That's.. bad. I read and understand that you are buying this car from someone else right? Is it modded?
My car now playing standard. Don't intend to modify until can fly. Yesterday tested with 0.7, very nice. Can feel the power. More than enough for me. =)
My fuel consumption now is full tank (RM 70 +/-) can give around 400KM. Fully highway, with some boosting and high speed @ 140KMH, can do about 460KM per full tank. Fully town with less boost, can go arounf 380KM. Boost here boost there, less than 300KM. haiz... Still consider okay.
So, what is your concern? You gonna re-convert back to original spec? GSR standard boost @ 0.8

 

[ken12292703]

I also don't want to fly. Your consumption is considered good. Mine is really really bad, i don't know what to do. Trying to stick to the stock standard setup as much as possible. Sad~

 

[kk9972]

Hi Ken,
For your case, why not try to change back to TD04 twin blade? Your current turbine which bigger than previous is TD05? If so, maybe you can trade in big turbine to get a smaller turbine. I think Zth-ian here should be happy to exchange with you.
Is Standalone installed? I saw somemore did install standalone and play with stock engine can have a very good fuel consumption. Im thinking to get one as well. May be SAFC.

 

[ken12292703]

Good idea bro,

Can a 5 button or 1 button AFC do the trick?

But the thing is i don't really know the engine is running rich or lean, gauges have to be installed as well? Any other way than looking at the spark plugs?

I am so noob. Damn...

 

[kk9972]

Haha, same thing goes on me. I'm very scare to up boost my baby. That's why need all the masters help and comment here.
Anyway, what is the plan?
My plan is up boost and see the result first. Then only decide to go for SAFC or not.

to kk9972......
i from pahang(Kuantan).....for your info befor this my 4g61t are 1.2bar setting...ok la boleh belah.....after that i tune my 4g61t and i change my gear box....now i use 4g61t 4wd full lock LSD gear box....and my boost now set at 1.4bar....last night i test with wira evo3 car(haram race la bro)......that night my saga buruk tapau that wira evo3....if u want i can send u the video.....terkejut beruk owner wira tu.....kalau kena setting memang blah engine 4g61t ni
