high comp? prepare to retune ur ignition timing... and of course might have to go RON97 too if too high.

but yeah...go dori dori and seek their advise.

the best is of course a combo of cams+high comp pistons.

but id go for cams... watever cams u go for do make sure that ur ECU can handle those cams.. if u no management, u need to budget for that oso if the cams u take are pretty high.

the only reason i went high comp with my engine is coz the engine letup.. so had to rebuild...since the engine was out....might as well high comp straight. had a slight issue after that especially since my management only had a/f ratio tuning and no ignition tuning option... whp stayed the same, though torque increased by 2.... with a very rough graph.

but now got something with a/f and ignition tuning and gained about 15whp....torque gained another 2 so total 4kg torque gained n a much smoother graph too.
n wat do u mean by "piston"head"? to increase compression u typically have to change the entire piston. u cant cut off the head of the piston only

Hi bro, basically i have everything for either high cam or high comp. I have Works Engineering EMS can tune ignition timing, with adjustable fuel regulator, etc..
So now after you change your ecu with ignition timing, you gained extra 15whp? That's wow. No high cam i assume?
Is there any jerking issue?

erm dun forget his 1 is VTEC, we are just CPS. and also the engine displacement difference.

Yea i just edited my post  .

coz they only change the heads, conrods all use back.

well what i meant was, dun expect that much of gain on our CPS, later u will get disappoint if the gain is lesser.

WORKS EMS better bro? emanage blue? which one better or any other suggestion?

except haltech or other standalone.

yup, emanage can only tune the air fuel on campro but not the ignition.

i thought e-damage manage cant use at all with siemens ecu? itll basically reset everything right?
n typically (for other engines at least) e-damage manage can tune ignition if u have the ignition harness.

Use haltech, at GT Auto, RM4.1k

yeah acceptable though i do recommend going high cam later down the line....i also planning on the same thing... just money no enough yet

actually if u plan on high cam+high comp... better to go high comp first... then at least u can run in the pistons properly...and when the cams come in... straight go onto the dyno.

either way... always... ALWAYS retune ur ECU whenever u make changes...

n 4.1k for haltech is actually ok la...

hmm let pistons run in first only tune right( after12 said).

right....but if during run in u experience knocking, better do some slight adjustments to ur fuelling and ignition to stop the knocking

thanks bro will update the result for you guys hehe.

hey guys..need help removing some black stain which i dont know caused by what

tried washing and tried using wd40 to try remove but no success. any of you got advice how do i remove such stain? i really dont know what kind of stain although it has been 3 or 4 months since i last washed my car
