What may cause this faulty idle ?? - VIDEO INSIDE -
All sensors work right, all vacuums were double checked and PFC is running on Base Map.
Idle learning process was done under the manual, no A/C and running Non Seq Turbos...

I got to a point that donīt really know what to look for...
Thanks a lot..!!!

It's not your injectors, otherwise the car wouldn't be running.
If you have a US-spec PFC, you need to cut the 4 wires on the ECU harness. You also have to adjust the idle air screw. This is all in the PowerFC FAQ in the PowerFC forum, make sure you've gone through that first then come on back.

As far as I read JDM FD do not need to cut the harness.
Am I right ??

TPS is checked, idle screw checked....
I will try fuel cut and ICV...
Tuning here in Chile is not an option, rotary engines is like a unicorn, no specialist at all, so hope to get it fixed with your kind help....
Thanks.

A surging idle like that typically comes from the ISC being stuck or the idle air adjust screw needing to be adjusted. Typically for a PowerFC you screw the idle air adjust all the way in then back out a half turn. After that you may need to do the idle learn again - do a full reset on the PowerFC, turn the car off and on, then do the idle learn procedure.
It's also possible you have a vacuum leak after the throttle body.

Glad it worked for you. The base map fuel cut settings are very low for stock so if your idle isn't right, it will surge like that as it cycles through fuel and fuel cut. Now figure out why its idling so high as that is too high for stock ports. Also, the base map is not safe for non-sequential and it looks like you have some flow mods done so your going to have to either find someone who will tune your car or buy a datalogit and learn how to do it yourself. We have a PowerFC group if you need help with this.
