Sudden RPM increase during idle..
Hello All,
I just installed Redom ECU B type on my FD and while I was test driving I noticed that RPM goes up and down to 2300~3000 during idle. And it goes to normal after little driving.
Could vacuum leak cause such issue like this ? does anyone have any idea what is causing this ?
All help is appreciated !!

I changed ECU back to Stock one. RPM no longer acts up. would it be possible ECU could cause it? I will have to check vacuums to make sure they are all good but geez there are so many of them.

There are 4 wires that need to be disconnected from the wiring harness for the PowerFC
to work properly. These 4 wires are for extra emissions devices that were added in the
US market, but weren't in the Japanese market. These 4 wires are for the EGR valve
control, the EGR switch (the feedback in the California ECU cars to tell the ECU the
EGR valve is working), the accelerated warmup system (AWS) which gives you the 3000
RPM startup when cold, and the Split Air Bypass solenoid, which can bypass air going to
the main cat back to the airbox.
