12A turbo revving problems - Need help
 
3 Attachment(s)
Hi guys,
I’m Karand from Bangkok.
I am super new to 12A turbo SA22c and really need help.
Am experiencing a lost power and sometime engine sudden stop when rev to over 5,000 rpm.
I check fuel pressure, injectors, spark plug, coil and any air leak possible I can see.
But still the engine showing the same thing.
I really don’t know where to start the checking and to look for.
If anyone experienced the same thing, please help guide me thru how to trouble shoot and fix this.

Also, please help recommend an EngineMGT stand-alone for this engine too. Is gReddy E-Manage good for this engine.

Really appreciate.

Did it run good before? Or have you always had this problem?

Have you checked your fuel filters? You can have good pressure when you are testing, but when you need to move a lot of fuel the fuel filters just can't move enough. (flow vs pressure)

Qingdao,
Pressure of the fuel pump is fine, new filter is changed and no leak in fuel hose.
I do not know how to trouble shoot this to confirm which part caused this.
Have a good day.
