I also double checked those ignightion maps and their the standard r33 maps that come pre-loaded on the pfc....

So did your tuner leave them as is....

do they release slightly differant maps in the diff versions of the pfc/hand controller maybe ?

I was comparing my ign map to the one in the faq, and in some points (outside of the first 10x10 range) they were off by like 10 degrees. I also compared them to the ign map in the FC PRO software, they was differant as well.. ??

Mine is pfc v 5.11, and hand controller v5.01A (might be the other way around)

Wered you grab the stock map on the faq from ?

[paulr33]

as far as i know the stock maps don't change very often

i havent at least heard they do. they were taken from my tune

but i may have done it before i did factory reset so they could be a "tuned" ign map. when i get datalogit, ill copy mt tune. reset to factory defaults then upload the defualt maps to my site and then restore my tune and upload that as well. ill expand the powerfc faq a lot when i have a working datalogit

Do you know how the powerfc calculates your speed?

[paulr33]

those 2 manuals are old as the hills and are for rx7. They are also the older powerfc so its not upto as the japanese SR20/RB25/RB26 manual.

it comes off the main wiring haress which i think is a digital output from the gearbox somehow, ill find out

[Col-GTSX]

It most certainlly a gearbox feed... The only other alternative is the ABS sensors but it still works on non-ABS skylines so it must be a gear box feed....

Plus the skyline has a digital sendor to the dash display....

hey guys i have a question for those in the know

because the nvct cam timing is constantly variable on the NEO rb25, can the PowerFC be mapped for this function, or how does that work?

with the r33 rb25 its either full advance or full retard no inbetween. and is activated by a simple on/off switch in the ecu at the desired rpm.

anyone know how the powerfc and rb25neo nvct perform?

is it completley mapable throughout the entire rpm band or whats the go?

[paulr33]

no idea but if you find out let us know, will add to powerfc-faq

the vvt on the rb25 (33) isnt controlable and its automatically controller by the powerfc emulating stock ecu functionality. you can see it turn on and off under check sensor / sw but its not controllable or editable in map form

[paulr33]

i dont believe datalogit or fctune can touch it either

[RB30-POWER]

with datalogit you can set the switchover point of the nvct on the r33 rb25 engine.

but the r34 neo rb25 is alot more advanced.

im keen as to know how much functionality it has.

Great work! Very helpful.

I have a question, which I hope isn't too silly:

Does the Power FC control the stock boost control solenoid?
