  • 2 weeks later...

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 ?

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

added boost control pics, info and wiring

added djetro harness and wiring and manal

added datalogit specific extra features

added datalogit logging options

added datalogit additional functions

corrected spelling mistake of my name

corrected double up paragraph

updated again:

added airtemp sensor on unsupported car info

added powerfc inside cover photos

added reflashable powerfc info

added custom hack / diy / hand controller holder pics

added basic hand controller use

added checking sensors

added checking functions

updated install info

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

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?

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

    • Haven’t had the chance to drive it yet with work being a nightmare, will definitely be doing that at some point this week. got these so that grip won’t be an issue at roll racing  
    • The cross sectional area of a circular hole scales with the square of diameter. So a 2mm diameter hole is 4x the area of a 1mm hole. Not double. The 1.7mm hole is nearly 3x the area of a 1mm hole. You do not need restrictors at both ends of the oil supply line. If you have new, additional restrictors at the turbo end, that you did not have before, then you do not need a restrictor at the inlet end.
    • Hi all. Been a while but things are moving along. I just have something that I am wondering about. Since I will use OEM turbo oil pumbing, I got myself a new bolt, the one that goes into the engine block oil feed. As I recall (and see visually) this bolt comes restricted with I think a 1.7mm hole? Not quite sure but it was something around that size. The turbos have 1mm restrictor bolts installed, as necessary due to ball bearings and my higher oil pressures. Can I now just use that OEM bolt with the 1.7mm hole in for the engine block or will this actually be too much oil flow restriction and I have to drill it out first? In my head it would make sense for the bolt to be at least 2mm wide as both turbos take "1mm of oil flow". Do let me know if my logic is flawed here, I just want to make sure I don't kill my turbo bearings with too little oil. Don't know if I can trust the saying I read somewhere that ball bearing turbos essentially only need an oil mist
    • There are several aftermarket options available, from not-too-painful moneyhttps://justjap.com/collections/driveshafts-bearings/products/d-max-reinforced-replacement-rear-driveshaft-set-fits-nissan-s13-s14-s15-r32-r33-r34-c35 and  https://justjap.com/products/crank-motorsport-billet-rear-axles-fits-nissan-skyline-r33-gts-t-r34-gt-t?srsltid=AfmBOorQk4xkGUa98kO7v2ePLUiNt-HRrM2AwWNw9mbSIVE1ujBVwY__, all the way up to The Driveshaft Shop https://driveshaftshop.com/skyline-cv-axles/
    • Yeah based on old XRC5964S specs, it looks to be roughly GTX3576R sized? But this 5964S compressor will flow 90lb airflow somewhat similar to the compressors in both the GTX3584RS or G35-1050.. I fully expected the 0.64 rear A/R to choke up top - seems way too small from typical convention - but these are seemingly beneficial over the prior 0.82 results.. Be interesting to see if he comments on the EFR question in that thread - he mentioned in a prior video that BW EFR's were the "cats pajamas 10 years ago", but by the sounds of things all his kits have been using Xona for quite a while now.
