Faq: Apexi Powerfc - Frequently Asked Questions

[justin911]

i think i read somewhere a untuned pfc on a r33 will do about 200-220km for a full tank?

does that sound about right ppls ?

[paulr33]

the stock maps are fairly rich for protection reasons but it should still enter closed loop on low throttle. as long as 02 feedback is turned on of course. 250km's to a full tank is resonable in an un-tuned state

Quick Question...

- AVC-R

Or

- Boost Controller Kit

for Power FC?

Is it personally preference of would the boost controller kit for the PFC be better cause its also controlling the rest of the engine as well as being cheaper than the AVCR (AVCR = $580) - (PFC Boost Controller = $400)

Give me your thoughts...

[paulr33]

both will achieve the same goal, the powerfc boost controller kit is cheaper

[sindows]

so no disadvantage/advantage over the two... apart from having an AVCR on my dash and someone decides the would prefer it off my dash and in their corolla

It has a bit of a wank factor... Also with the PFC do you have to leave the commander connected all the time, can you like take it on and off at will if its in the way or soemthing?

After reading the faq, I still needed some more convincing on the PFC with an auto, so i've made a new thread so as not to bring the conversation into here:-

So yeah, i want to know once and for all if the PFC will work with the auto.

Cheers.

hey ive have plugged in my power fc and its hasent been tuned yet.

the engine light stays on and the car constantly stalls. it also feels like its skips and hops going up through the rev range. all was fine with my stock compter.

i need to keep the powerfc in fow a couple of weeks till i get it tuned, is there anything i can do to fix it? like reset it or sumthing?

[paulr33]

make sure the boost controller kit is turned off (says that in the faq) and if that doesnt make the engine light go off, try a full reset via ETC then turn the key to ACC, turn off boost control kit and then start car and let it idle for 20 minutes. follow the procedure correctly for first time "init" of the powerfc as it has to learn the idle

I dont know if this has been covered but I just found you that you can get number rating for the knocking levels with your car.

Just press the UP arrow, and it will show digits for knocking. So basically it will show you the peak, in a digit and not just upon the bar graph

Paul

I bought a AVCR boost pressure sensor from Nengun. I have a 3 pin plug for my power FC. It reads boost but its wrong. I have my set my boost pressure at .65 bar via the power fc to read 20psi at my guage. My low boost is set at .50 bar.

I believe something is wrong with the boost pressure sensor? I had to manually wire it up as it didnt have the correct plugs. Any ideas as i have double checked the wiring.

[paulr33]

sorry robo im a bit confused. i dont know for a fact the avcr map sensor is the same, it should be. can u give me the denso part number from it. the map sensor should attach to the 3 pin harness. the boost solenoid should attach to your stock wiriing. when you goto setting, boost what option is highlited and whats it set to ?

[hefer81]

in the airflow selector option on the hand controller what is the power option there for

[paulr33]

for the apexi power intake kit, i believe the voltage ramp table is slightly different over the standard rb25 airflow meter.

[boodsGtr]

how can you tell if you have the pfc pro?

[paulr33]

ETC, VERSION

if you have normal powerfc

RB25DET

if you have powerfc pro

RB25DET1PRO

heres one for ya, my battery went dead flat and car sat there for 2 weeks, i jump started the car from a charger/starter pack and now engine light is always on and car stutters while cruising every couple of seconds. We went to a local tunig shop and they had a customers car with brand new power fc and we used that commander as i dont have one for mine. It plugged in and just came up with the apexi logo and thats all it would do. Are the commanders only suited to that specific ecu of should it have worked? Also any ideas on wether something has been reset or blown due to the flat battery then jump start? driving hard it seems to run fine with no stuttering but its when you sit on a constant cruising speed and also does it worse under less load. also after working on it tonight the voltage off the battery is at 14.8-15.5 volts whilst running and the battery light is now on!!

Bet ya this stumps ya!! lol
