try to check ur steering rack vacuum hose, if tertanggal or poor hose condition will cause the problem u mentioned..
if everything tried, it's time to change blacktop wiring running MAP...hehehehe!!!

 

[Cronixz]

I realize my steering rack oil seal is kind of leaking .. but very small leakage... could it be due do that???

kimi; u from svt to bt full wiring? how much tis cost??

Nop, use back SVT original wiring. Only bought BT ecu. MAP and Air Intake Temp sensor use from 4AFE. Re-pin ecu socket to match it with BT ecu.

 

[alex_khoo]

use back svt ori wiring can kah? how long u doin tat? any problem? can share cost n where to done it? thx

 

[me2kimi]

yes bro. use back SVT wiring. Forgot already how long to do it. maybe only take a day or two. I do it at my house. DIY. Hehe. So no cost for workmanship. So far use it with no problem

 

[feipepe]

kimi,
can u help me to do that?....i can pay back the money to u...

 

[me2kimi]

feipepe, are you using auto wiring? If you do sure i can make it for you, but if you is using manual wiring, there is a bit problem coz ecu socket didn't match

 

[feipepe]

kimi,
thanks for ur prompt reply, in fact, i using svt manual...u meant the ecu socket not match? is that need to changes the ecu to blacktop? if not, how comes can't used back the svt socket? if i not mistake, svt manual socket are sames with svt auto...

 

[levin818]

...... if i not mistake, svt manual socket are sames with svt auto...

They are diff...
M/T is 26p-16p-12p
A/T is 26p-16p-22p

For BT's, both M/T and A/T are 26p-16p-22p

Some interesting project yeah...
Remember to solder & isolates the socket's pins properly.

 

[me2kimi]

Like Mr. Levin said, it's different.
SVT manual pin is 26/16/12 but BT (auto&manual) are 26/16/22.
The problem is for the third socket. If solder it, it will be bigger problem to remove if the ecu got problem at future.
As for me, I just put single wire to each pin without socket so that ecu can be remove.
But it's my car and if something happen I know where I have to look to.

Unless u can find 22 pin to replace the 12 pin.
