14-19-lean
9-12- high

since u said ur's is 13.5, its good enough. tuning it richer or leaner might even decrease the HP. DId you tune it using a dyno?

Ya bro, because i replaced my works engineering brand RM280 to original Sard RM390, both set to 3.5 the sard felt much better, no whistle sound, good pickup and smooth, no more jerk.
I want to know if the graph the tuner decrease or increase the psi to make the 12 A/F Ratio(blue) to 13 A/F Ratio(red), hard to explain, just want to know

Blue and red, A/F graph below.

usually reduce afpr pressure to make lean afr, higher pressure rich afr.

Wrong, http://www.turbobygarrett.com/turbobygarre...ng_rich_vs_lean

that article got nothing on FPR also.

what la.. u asking people which one to make rich or lean with afpr pressure.. and im giving u the hint then say im wrong..

You set what bar edi, without the vacuum hose plug in
we chat in pm before, i lazy to check back, your horsepower 124 on wheel right?

chill bro

BAHAHHAHAA..funny la you guys

can't remember what bar already, have to open hood and check back.
And its irrelevant to me now since the AFR is control by unichip already.

124 whp on wheel? Feel like changing to unichip..

just 121 whp and 15.16kg-M torque

After all those tuning..how is it able to perform on track ah? I'm considering actually

Minor mods,
recommended mods:
BC v1 suspension
R3 full exhaust
K&N Drop in.
Unichip.
Iridium spark plug

Other mods are maybe useless like
open pod(Unless u manage to make it suck cold air),
adjustable fuel pressure regulator(Unless u modify pistons, highcam etc)

So far mine is:

Local brand suspension
Local full exhaust set
OEM Drop-in
Stock ECU
Local LCP

Can go below 3' at Sepang?

Don't forget to upgrade the brakes also.

Pads changed also already..forgot to mentioned..haha

What's the estimated target time at Sepang? Got benchmark?

Not sure, but lcp if not mythelogy brand better don't change for engine reliability...
