walau....ijoe...y u not using mivec piston when u using mivec head?wat better piston u using..share skit coz i plannin 2 put mivec piston too

 

[dareMAX]

ya oo, I think so, but where do you install your SGTI TB? any recommendation? I am staying in Cheras bt.9. and my ECU is 5660. is your ECU same with mine?

My problem is after install SGTI TB, the engine rpm run at 1.5K and switch on aircon is 2.5K, if change back 4G91 TB, everything normal again.

After installed SGTi TB 1.5K rpm. Did your mechanic fine tune for you? Shouldn't be, coz some member here are using 60mm also no problem.

Or you bought Siemen SGTi TB?

How long u use before it kong arr? Mine already almost a year I think.. I thrashed it everyday.. still gud till now..

Hmm, more than a yer oledi.. i also drive damn kaw with it.. hahahah.. it is konged becoz of the jammed clutch bearing eating up the clutch cover diagfram.. if not i think should be able to last for at least 6 month to one yer.. the plate still ok..

For sure is the TCU engage in protection mode...GB kong...change to manual or rebuilt it or get a recond one

recond one around 6XX....gamble game....may another problem

For rebuild
Sun Eng Hup - RM1800
EH Auto Link - RM2500
M-Scope - RM3000

Add in ATF Cooler
Sung Eng Hup - RM500, made in USA
EH Auto Link - RM400, dunno where
M-Scope - RM900, Made in Canada

Hehehe....about the same price for another halfcut......stick to auto or change to manual is up to you

My mechanic tune the scew max oledi and only can lower to 1.5K, do I need to change the ISC & TPS to 4G91 type? play & play really cannot work~

the tuning you refer to the one screw (near the isc) on TB only or other part?

:emoticon_U: , the problem is came from your TPS's voltage to ECU, if your machanic experience enuf he shud know to slightly adjust the TPS to cheat the ECU, not exchange with your TPS, dun let him do, get another machanic do it, otherwise both ur 91 and 93 TB koyak then u know

Ah Yong place ah? I never being there, maybe some taikor here can point you there...it just common sense the TPS is the point to adjust...me myself still runing 4G91 original TB, maybe those change before can guide you to reliable workshop, e.g. our pres mr tajulsans :shades_smile:
