i have a pfc for a 94 sti, how can i tell if it has the optional boost control, does it need fitting or can i see from looking at it, cheers phil.
also i am going to be running without an air flow meter and induction, can the pfc be programed to run like this, if not what will i need for it, cheers phil.

 

From my understanding the PFC cant run without a maf sensor,the boost control option is a map sensor that plugs into the side of the PFC.

 

the boost control kit is a map sensor and 3port boost solenoid, ie. physical parts that need fitting and you are unlikely to have them.

You cannot run it without a maf sensor as wrxbart says.. there are no djetro powerfc's for subarus unlike most others.

Simon

 

The man knows his stuff,
By the waySimon does the maf need to be in any special place in the new pipe?
Cheers Rob

 

away from the turbo.. the issue is the large turbo you are planning to use will create a fair amount of turbulance.. if might be worth putting it in the intercooler pipework.. although that causes headaches too..

I still wonder if it might work out easier and cost less to go Link and sell the powerfc and z32 maf sensor.

I'll try and ring you tomorrow to discuss.

Simon

 

Ok mate cheers just like the apexi thats all,i know that the maf in the intercooler pipe work can cause probs.read the thread on here bout it

 

thanks for the replies, so it looks like ill have to get the boost controler then, one more thing, how did thid guy get it to run without the maf.

 

He cant of been running a apexi then mate,if the pic above is owt to go by

 

oh, so the apexi isnt that good then, what could be used instead to do the job.

 

The apexi is a very good ecu but cant be run without the maf.mines run with it at 450bhp for 2 years and no probs.The simtec is a great maf less ecu or the solaris i think,there are others like motec,link,hydra,etc

 

the car in the picture is also a newage and there is not Apexi for newage.

what is the power target for the car?

Simon

 

im aiming for 500, what ecu would you say i will have to get instead to run mafless?

 

Autronic, Motec, Simtek, Solaris, Haltech to name a few - the choice is yours.

Choose whatever fulfills your requirements, is within your budget, and is familiar to whoever is mapping your car.

 

just been looking at the link ecu, it looks like they can run mafless, unless im mistaken, what sort of price are they, and does any one want to buy a pfc, ha ha ha.

 

if I fit the two secondhand pfc's I have here as planned over the next couple of weeks I might be interested in part exchanging it.

I did a review of MAP ecus a while back.. Link G3 not the newer G4 admittedly but the features and cost was out shadowed by the SimTek and I then became a SimTek dealer..

I don;t think you will find an ecu with the same features fitted and mapped for the same money. If you want the daddy and have more money to play with then the Solaris imho.

Simon

 

very good, do you mean a deal with the simtek one as you deal in them, what sort of money are they anyway? and do they run mafless, please say yes, im getting a headach now, ha ha.

 

yes simtek are mafless, its what i'm looking at

 

I meant as in I do take pfc's in part exchange if I haven't got lots in stock already

I map anything but only really supply pfc, SimTek and Solaris.

Simon

 

right, im glad about that, so how much do you sell the simtek for, as i think thats the way ill go, where abouts are you too.

 

south east but am fully mobile and up in midlands every two weeks and stay at a mates in..... .Derby

pricing is on website

Simon

 

thanks very much ill take a look on the site, then im off to bed, i think ive had a bit too much wine, by the way look at my thread in projects (rs200 impreza) for a look at my setup, ill give you a call soon, thanks again, phil.

 

hi again, will i still need a 3 port boost solenoid when i get the simtek, thanks phil.

 

yes.. but the car should have one as standard

 

i thought that when i asked about it before, there are 3 pipes on mine, the bottom one is just a pipe going nowhere,
so this standard one on my 94 sti is ok to go with the simtek and and external wastegate?

 

The bottom pipe on the solenoid is just the vent - It can either be recirculated back into the inlet tract or just vented into the bay (as long as the hole back into the inlet is blocked off)

 

yes thats how mine is, vented to the bay, will mine be ok to run an extarnal wastegate and simtek then?

 

Yes

 

thanks very much ill be in touch soon for the part exchange and remap mr jolly green monster.

 

just thought, will i need a 3 bar map sensor to run with the simtek.

 

I supply one if needed, with your planned turbo it will be needed.. lol
