waaahh.. this topic refeash very fast ... cannot catch it .. :D

I also face the ISC problem, and this is the third times i change it . Now try my best to calebrate it , hope can minizine it.
I check prevs few pages, that's have 3 screw on throttle body to calebrate AFR; but when I check back my throttle body, I found that are no screw ; furthermore there is only one hose which is printed with " P " connected to a black bottle.
so, should be cannot tune on it .
anyone know about it ?? pls advice.....

lampakia...actually i got those tools 2 do some minor porting 2 my intake port...just tat i'm lazy 2 take out the intake manifold...a lot of work...
so far me n lampakia still havent got any prob wit the ISC coz mayb our halfcut we bought very low mileage...
mine is 39k km onli when i bought n lampakia's is onli 20k+ km

 

[boyzone]

u all r so lucky ....

I read a technical paper, the editor said that ISC will stand at 50k to 65k km only, after that, is time to change it liao ....
that's why even though we brought from chop shop, we also face the same problem after some time.

Did u guys know how much is the brand new ISC which is selling at spare part shop one ??

 

[lampakia]

huh...last onli 50k to 65k km? then after tat where can we get new one?

 

[boyzone]

for them, they can purchase the ISC by online, but not suitable for us ,because of currency. since we have 4G93 on Malaysia, i think should have brand new from spare part shop right ?? anyone of u have a good deal with spare shop ?? can ask them or not ?? want to check the price :D

I will look for brand new one, dun want to waste time change this check there and tuning for everytime.

[LancerTerabo]

wow so detail thanks bro. just one more question. when i set my timing that time. should i turn off the micro compressor? does it affect anything? so many screw thingie... very blurred and confused la. thanks again.

by the way lancer taiko, how to tune AFR? reset ecu won work la... i try before. if wanna tune injection. how they gonna tune?

actualy if we want to tune ECU, we need handytools call Hi-Scan, MUT, and wat so ever. Some of workshop do not have goot MUT or Hi-Scan ting. 1 Hi-Scan coz about 1 new kancil. so almos all tuning workshop just have cheap MUT only. ill try to talk with my xbos if he can give a tune for 4g91. coz his hi-scan socket is for KIA (tiap engine nyer socket lain, tak tau la dia ader ke idak socket untuk mitsubishi)

im no taiko la... im still new with this ting maaa... oh btw, fogot to tell la... about AFR, ive read that we actualy can set AF mix every deg and RPM. so that when initial to start move, actualy its set a little rich. for cruising change to lean. then we going for max speed, they give more fuel. if not mistaken, in your ecu got isometry setting. it will set your fuel / air in defren RPM.

to set timing. i thing, u try tu set without turning off your micro compressor. coz normaly, setting will lari again when u usik that ting.

cam nie la... to those who want to be tune or check maybe can folo me to my workshop. maybe my bro can show/advise u what the best thing for yer engine. oh ya... ive ask him about labour changing 91 to 93 cam.

another thing. i can get Caltek Fully Syntetic for only RM98 eni wan want can calling me or pm me. thanks.

i DIY project over the weekend...
i took out my ISC switch with the intention to ruin it...so dat when i fix back my FICD there wont be any interuption fron my ISC... but when i dismantle it... i f wound the ISC dirty full with carbon deposits.. so i gif a try by cleaning it using a white greasy spray(like WD40) on to it... after cleaning it i install it back... start engine n suprisingly found dat my idling is much much stable then b4 n the engine vibration is much smoother(but problem not completely gone)... after dat i when change my fuel filter... now i feel the car my smoother during low rev n FC seems alil better... normally rm20 i can get 100km the max... but now rm20 already reach 140km with alil more petrol... tonite im gonna pump again and monitor if the FC has improve.... other then dat i think i wanna ask my previous mechanic who did engine convertion 4 to do MUT tuning 4me... he does MUT 4 a minimal charge... if it can solve the idling once and 4 all gud lar....if not haf to change complete TB wit ISC, no other way can solve this problem...

use carb la bro.. .can join me... wakkakaka... im onli 1 4g91 carbie user here (from kl) another fren working in johor. like other forumer said, carburetor easy to maintain. but still hard to tune. like my ride. to get smooth but power. to many parameters need to set. as we know, normal carb only have 5 stage, but 4g91 carb have 6 or 7 stage. and every stage give big effect to peformance. (now im using normal 5 stage carburetor).

if u going for unlimited rev without any rev/speed limit, carburetor is your best choice. but if u're just going for drive and rembat and stop (tak nak check sendiri) i think better u choose injection. only sensors problem. but no need to be set frankly.
