GSR rev cut prob...

[11000RPM]

Sifoos, i encounter a prob...
Sigh...
How come my gsr rev cut is only 6500rpm?
:frown:

my ecu number is 7377, dunno auto or manual...
Sad...
:frown:

How sure are you that “cut” is not fuel starvation or maybe boost cut? Which is basically a tuning issue.

Thanks bro for your reply,



Anyway, I’m not very sure is it a boost cut or rev cut… When my car reach 6500RPM like that, it’ll ‘fart’ poo poo poo like rev cut. But it can go up some more to 7KRPM +++…

So my friend said it may not be rev cut. I don have a boost meter now, so I can’t check the boost level. My friend said maybe over boost, some say wiring prob, some say not enough fuel, some say boost too low, kekekek…

I also dunno how now…

Can anyone suggest me something?

Thanks!

I wonder why people spent a fortune to do engine transplant, and on performance parts but unwilling to spend their money on tuning. Blowing a GSR engine is quite expensive, and tuning cost – maybe around RM200 is puny compare to it.



Normally, when a car behaves like you described it is either fuel related or ignition related problems. Go find a workshop that has wideband sensor and tune your engine.

Hi WEJ,



I just only transplanted my engine, kekeke… So dunno about tuning and etc coz I tot it was tuned… Anyway, I’m sending for tuning this week, I think it’s fueling problem… Thanks for the advices, thanks a lot…

PS: Your car must be very well taken care…

maybe ur car over boost...
do u have any boost controler?
try to set ur boost low.. such as 0.4..0.5
then if the prob solved.. u can up ur boost slowy..slowy..try 0.6..0.7..etc

if u hvnt boost contller... mungkin piping turbo bocor... or vacumm tube leaking..

 

[dolly]

you can't set the boost lower than the wastegate setting, so i dont think he can go to 0.4.

Stick a wideband o2 sniffer up your exhaust pipe and check the afr. like what wej2719 said, if its all good check your base ignition timing

 

[11000RPM]

Wow wow thanks bros...

The vacuum pipe got a thing like fish bone but it's wide open, maybe over boost lor...
Must fix this ASAP if not later kaboom!!!
