How-to: 4A-GTE and Apex'i Boost Controller AVC-R Blue Wire?

[JBQ]

Hi Sifu,

1). From the drawing diagram:-
a. injectors #1 & #2 join into G-Y wire which leads to pin #11 of a-type (26 pin) ECU
b. injectors #3 & #4 join into G-R wire which leads to pin #10 of a-type (26 pin) ECU.

2). The pin #10 is also dubbed as "VSV Fuel Pressure".

Question:-

How to connect the blue wire (injector signal) of Apex'i AVC-R into 4A-GZE ECU since the ECU has two pins connected to the 4 injectors?

Regards.

I need to make sure that they install for me correctly. I've lost one half-cut due to workshop negligence.

my advise.. dun go for the injector connection option... just go for the RPM signal wire.

Thanks. Please advise me the reason behind it because I need the injector's duty cycle displayed for adjusting boost.

you can't get accurate rpm readings for certain vehicles if you tap it to injector signal.
the self learn feature is pretty difficult to tune with.
