ok im getting my fmic fitted this week then getting the car remapped via apexi power fc...

any guesses to what i might reach in bhp ?

heres my mod list.

full haywood & scott decat stainless steel exhaust system
Td05 16g turbo
hks power-flow air filter
Walbro 255lph uprated fuel pump
440cc injectors
baileys dump valve
aftermarket intercooler hoses
Autobahn fmic

IRO 320 depending on what boost you run Less if you haven't got the AVCR as your boost range will be limited

Bear in mind anything over 300 with the corresponding boost required to get there and your B4AA gearbox won't be long for this world if driven hard

I thought you were selling ? I asked how much on the ESOC thread

EssexMIke555

i was going to sell but ive spent too much money on it.. going to keep it now

53

iTrader: (41)

lol Have you got the AVCR ?

EssexMIke555

No I got a manual boost controller but that's just so I can lower the boost, I never boost higher then. 1.0 bar... Can the boost not be set through apexi power fc when mapped ?

iTrader: (41)

Only so far and you need to set the target lower to avoid overboosting and cutting. IIRC it can only read to 1.1 or 1.2 without the AVCR set up, but I forget. Really with those mods you want the ability to boost to 1.3-1.4 in the midrange, otherwise it will be a little meh !

fit a later spec map sensor if you want to run more boost and you should see 330 with those mods. my wagon made 315 on an andy f map but still on the small slanty ic with similar mods to you. he said with a fmic and induction we could maybe hit 340.

iTrader: (41)

The later map sensors don't work particularly well with the Apexi, you don't get a particularly smooth boost response from experience. They work well with other ECU's/Daughter boards but for some reason the Apexi needs the AVCR to run acceptably. Just my experience, others may have had more success with Apexi and later map sensors

I would personally fit the AVCR (I have done ) as it gives you so much more scope when mapping If I were doing it all again though I would just go with the new ESL set up, the only thing I would miss would be the Commander

EssexMIke555

So gotta spend another 300 quid on a boost controller ... Great lol

Agree with the MAP sensor if you were not going APEXI, also boost solenoid, replace prior to mapping as this can be a weak point (as in my case) and also the plugs

If i knew then what i know now i would of changed a few more things as its dis-heartening hearing If you had fitted.... when being mapped LOL

EssexMIke555

Out of curiosity... What would happen if I plugged in my power fc and run it with a manual boost controller ?

yabbadoo4

iTrader: (8)

you could just get the apexi 3 port boost solenoid secondhand and fit that and then let the apexi control the boost. cheaper than buying an avc-r.

EssexMIke555

That will seriously work ?

MattyB1983

Sell the old fashioned apexi power fc and go ESL instead.

ESL costs £295 plus mapping and is a far better option than PFC.

53

iTrader: (41)

No it wouldn't

If you don't want to buy the AVCR and want more power that matches the mods you have done, go ESL as Matty says I would have done if the new one was out in time but I wasn't for me. You'll get a good price for the Apexi as they are still really good

EssexMIke555

I'm going to get a used avcr from eBay... Can I get any kit ? Are they universal or do they need to be specific for v1 v2 imprezas ?

MattyB1983

iTrader: (51)

Yes they are universal.
When ive used them they wire into the ecu but I'd guess they are plug and play with the PFC.

In my opinion you're going to needless expense keeping the PFC. I mean the avcr alone will cost you almost as much as the ESL. And once its all mapped you'll have a pretty basic management setup.
No doubt you could sell the PFC for £350.

EssexMIke555

so if i go esl i can max boost with no extra mods ?

53

iTrader: (41)

As far as I know you would still need the 99 STi or equivalent map sensor

The Rig

iTrader: (13)

yeah, MAP sensor still required, original is max`d out at 1.2, later spec one is to 1.6 i think but you need a good gearbox to cope with that LOL ha ha

iTrader: (8)

just curious why the apexi 3 port doesnt work with the apexi controling boost? im pretty sure it does!

MattyB1983

iTrader: (51)

Speak to your mapper. He will know exactly whats required.

just to add another plus for the ESL it is also mafless and twin maps

EssexMIke555

Ive plugged in my power fc and reset it to basemap.. The car wont rev past 4000rpm and wont boost.. Do u think the power fc is faulty or will it just need mapping to my car ?

53

iTrader: (41)

Lol your edit seems a bit more miffed than your original post

It's not so much about controlling the boost from a solenoids point of view it's about being able to map the boost safely above 1.1 bar. You have a 3 port anyway in the early classic but it's not about that Without the control of the AVCR set up you have restricted mapping.

In addition you would still be restricted by the V1/2 map sensor so it's not really worth faffing about

53

iTrader: (41)

You need to wait mate the PFC base map is pretty aggressive and will not be good for your car Besides which you have to go through a reset and learn process which is pointless until you are ready to roll.

Put the old ECU back in and wait till everything is installed and the mapper is sitting next to you

yabbadoo4

iTrader: (8)

not a good idea m8! remove it until mapped! the base map is very aggressive and tuned for japanese 100 ron fuel. the timing is aggressive also. just be patient bud. i know when u get it you want it on but running it like that is bad for the engine. mine sat for months until i got my injectors and other mods ready so know what its like.

yabbadoo4

iTrader: (8)

but its an option that works. sorry didnt mean to come across as miffed lol but i know it works. yes they say the apexi isnt that great at controlling the boost but fitting a late spec map sensor and the apexi 3 port and letting the ecu control it does work.

The Rig

iTrader: (13)

On a side note, ive never really understood the twin map of the newer ESL, i mean, if your driving along and traffic light grand prix scenario occurs LOL, you would need to turn ignition off, tap throttle twice or whatever the sequence is then get going LOL all a bit of a faf, unless you can wire in a live swap over of maps ???

i can see its use in a road/track car but not anything else

EssexMIke555

Ok im going to get the avcr and map sensor... It will cost me more in the long run but i like the idea of having the hand controller for monitoring and controlling boost from inside the car.. :d
