Apexi Power Fc

It won't with a decent ebc, one that automatically sets duty cycle to suit the target boost pressure. i.e you dial in you want 15psi, the ebc does the rest.

I can see how the novelty of being able to dial up boost would ware off very quickly. This would also save me $$ to spend on other things.

Say i buy the PFC without the boost solenoid then tune it to a "safe" PSI. What would be a "safe" level for my car as i have done no engine work. only FMIC, ZORST, POD FILTER. I've found 12PSI to be the most common answer but then occasionaly 14-15. Does anyone else with similar mods run the higher boost???

[Robo's]

Ive got the PFC boost controller with 3 boost settings. On hot days i change to a softer boost setting. On cool days or when im out cruising with the boys, i select high which is 20psi. Ive got a an aggressive tune so with high boost i do see some knock (60+). On a hot day i would certainly hate to select high boost.

As far as in gear boosts variations, this would be a handy feature to some high powered cars. With my old 255/40/17 Sumo's this would have been nice in the first 2 gears. But i bought some Street R compound tyres and now i get full traction in any gear.

My 2 cents worth.

if you (or anyone) was able to get their airtemp sensor working you can use the air temp vs boost correction table in the powerfc, you can see these settings via datalogit. in fact theres a few tables for boost correction that you can't see on the hand controller which datalogit shows you. such a shame we cant get the airtemp working

[Bl4cK32]

you can get the airtemp working.

Use the gtr sensor, and wire it in. A few peple have done it now...

[NateR31]

you also have to get the AP Engineering pfc, as apexi dont make one for a rb20det

Anyone know how to brighten the lights up on it? In the day light its very hard to read.

There's an option under the etc menu to adjust display properties.

please tell me who has it working on rb25det powerfc

Yeah tried that but still its pretty crap, i suppose im being fussy when the sun is on it

[Bl4cK32]

<{POST_SNAPBACK}>

I was referring to the rb20det pfc, as it uses the r32/r33 GTR power fc (just remapped by AP engineering) That is why it displays the air temp on the rb20 hc still.

I dont know if the rb25det displayes air temp on the hc, as i dont have a rb25 pfc.

Obviously the rb25 uses its own pfc version, not a remappped gtr item, so it wont have this option available.....

[paulr33]

hey sorry, i knew rb20 has sensor display and works if you plug it onto the ecu. the rb25 ecu has this menu item as well, and all the tables and it just displays airtemp as ---. i tried to hook it up and fried my ecu doing it so thats why i was keen to hear from someone who has done it on rb25.

Should i assume that uve done engine work to be running 20PSI?? that sounds like pain for stock internals. I would only look to have 2 boost settings if i set this up. id prob want 9PSI as low boost and 12PSI for high. i'd be too worried about doing damage if i went higher than 12.

High boost is fine providing its tuned well.

[paulr33]

i believe this thread should be kept open for general apexi powerfc chit chat as there seems to be enough to warrant its own thread.

ive just noticed that nengun has listed the mainstream powerfc pro as discontinued and only ap engineering customers have acccess to pro options

> Please note: Recently Apexi have stopped producing a number of Pro Spec > PFC`s and H/Cs. Please do not purchase a Discontinued Product.

standard rb25det powerfc pro is no longer available, like the others

dont leave it in the sun, the screen will fade and just get worse, put it somwhere where a shadow casts on the screen

[GTS4dood]

OK, there seems to be a fair few ppl out there that have the Power FC installed. Ive read a FAQ on here that the avg price for tuning is 300-500. im gettin quoted from 450-700. I live in newcastle. so im willing to go to sydney for example to get it tuned if someone can recommend a quality tuner at a good price. a 4wd dyno would be good too. but i can switch it to RWD. would there be much of a difference in the overall tuning???

[GTS4dood]

most tuners are telling me to get a seperate boost controller i.e. AVC-R. im almost being warned off the boost controller kits that apexi make as an add-on for the power fc. why would this be as ive had ppl on this thread say that they are fine?

[paulr33]

the apexi powerfc boost contorller kit is fine and works fine.

ive heard mixed reports about the avc-r. the avc-r is very expensive. the powerfc kit is half the cost and gives the same functionality.

[Bl4cK32]

The avcr is the exact same kit as the pfc boost controller uses, except it has the pretty blue screen instead of using the h/c to display things.

Im running both avcr and the pfc together with no probs. Its the best controller when setup properly.
