Need help improving SEG converted to blacktop

[Veloc]

wan to try faster try lor... wanna sell d.

nommiey,

few minor stuffs for u to eliminate the low rpm knocking sound. it's not harmful to knock at that range of RPM but i know it's annoying. sounds like 4G13P/4G15P. Just make sure it doesn't knock above 5k RPM then u are safe. the 4 throttles knockings are quite common.

Try changing to colder plugs. Possible that your combustion chambers are full of carbons; try using carbon cleaner or something like that. Use RON97. Check ignition timing see if it's too advanced. Ask doctor ecu, levin818, to check your ECU. Aged components might be the cause as well.
If neither of the above solves your prob, and u can't live with that knocking sound, get a piggyback or a standalone which would be your best bet to solve it.

Bro... Where got people say knocking not harmful wan oh? Its common for an aged BT to knock, but that doesn't mean it's ok... Have to try to eliminate it also even if it is at 4k rpms... Knock really damages engine. It may knock at 4k rpm and nth happen. But that's just because its a matter of time. For a while, it doesn't really matter. But in the long run takaan just leave the knock alone right?

i know what u mean, maybe others can shed some lights?

Knocking... retard your timing to 10deg
If still knock --> check your ECU (for all SVT and for BT BZG)

List of 20V faulty ECU that visited my clinic:
89661-12770 SVT M/T
89661-12771 SVT M/T
89661-12780 SVT A/T
89661-12781 SVT A/T
89661-1A180 SVT A/T
89661-1A190 SVT M/T
89661-1A470 BT M/T 5sp
89661-1A480 BT A/T

Hope this help.

i highly recommend these :

1. take out ur original trumpet inside the plenum..
2. TOM's super air intake
3. AE101 levin/trueno original exhaust (twin muffler)

Bro levin818......i also hv the same problem n after checked wiring n sensor all is ok,i suspect ECU too...u got any good condition BT 5sp for sell??

Yes bro. Please check your PM.

did you swap the fuel pump? try to check you spark plug 1st, maybe air fuel ration not match.

Ah haa...using velocity stack (VS)...

there's a way for you to drive it...if using stock plenum, the air inertia will be there...
but for open style like VS...you need rev it high...only the you'll "Get The Feeling"...but make sure it's tune up to the engine spec...experience 20V mech will know how...

VS are not recommended for daily usage...as it will inhale all those un-filter air straight to you engine block...once a while it's OK...plus, not everyday you're going to rev it high... :D

Agree... 2.3 - 2.5" depending on where you want your powerband to be. But since our friend here complain about the lack of low-end torque, I don't think changing to bigger diameter will solve the prob because then she will need to rev even more to get the power.

Why not, try changing it to straight flow muffler first... Leave the pipe intact...

Hi all,
Sorry to interrupt. which exhaust piping type is better for BT 6spd on a SE ltd chasis? Need advise from otai2 here...

1. 2.3" after flexi pipe all the way to the muffler (using standard SE exhaust longkang - many 'L' curves)
2. Or 2.3" straight flow (not using standard SE exhaust longkang) after flexi pipe to the muffler?

r u on open throttle setup? if yes then use the plenum back.

so...
it's not advisable for a daily driven car to use open trumpet eh...?

Levin 818... You pwn us all

Only u urself a mech&are not reluctant to open the ITB more frequently to clean all the dirt..If not, then u hav to drop ur ride in workshop&surely it will cost u...need fun,hav to sacrifice amount of money

 

[nommiey]

haha.. now you all talk techie and now i m lost.. hahaha

 

[Mohd Faizal Mahmud]

Haha, I really am a lady driver. :) but I like cars but never had the opportunity to learn much about cars. Started driving with toyota LE when I was 18 and fell in love with toyota since then.
Thanks for the info.. so next step is upgrade the exhaust system right? since mine is the stock local AE101.
