PowerFC tuned today, problem

[T0nyGTSt]

Hmmm... I run the standard AFM too and I ping as well!

At high boost, heavy power usage.

My z32 is imminent (thanks to Philip!) and I'm doing a fuel pump (either a 040 or 984 - doubtful whether a 044 is in the cards

Sooo... I'll get back to you guys with just the z32 and Bosch.

Injectors, reg. + plenum is some while off for me I afraid.

Mark - you need to get with Northside sometime!

Have you sorted the problem out yet.You could try looking at your tps if that is set up wrong it can cause problems. If the tps reads anything over 5.3 volts it will make your check eng light flash

man just get some 550cc injectors, z32 afm, bosch 044 fuel pump and take the car to a guy that knows how to tune a pfc and make full use of your high flowed turbo!

sounds good on paper.

haha? or just buy the Mines R34...that may fix it for good

i mean common, he is looking for a cheap solution, i suspect?

not to fork out $2500+

Injectors, z32 and 044 should not be too expensive I would imagine?

i am doing this at the moment plus about 5 grand of other stuff

what buying Mines R34 and going to add what to it for 5000.00

jokes..

thats good to hear mate...let us now how u go.

[MRK25T]

I've already got the fuel pump so another one is not needed.

I've also got Inasnt's old blitz BOV in (at last).

I've been too busy to do anything with my car, looks like i'll be busy on the weekend too - gf has an assignment due which i'll be doing. working 6 days + uni assignments = not much time for anything else.

Killer: where can i change the idle? my car is idling at about 600, shouldnt it be closer to 8 or 900?

maj: nope, i havent cleaned the injectors, but a week ago i bought some of that injector cleaner from a car store (just for the hell of it) and poured it in the tank.

Tony: I have a couple of times. I've been to meets/cruises starting at burger king and chatswood.

i ordered my pfc today and should have it in 7 or so days!

what fuel pump have u got man? I am getting 550cc injectors so i wont have to fark around with problems like u r experiencing, u should invest in some also man!

[Majanal]

Might be worth doning Mark. Making sure that everything you have is working efficently and proberly first is always cheaper than spending $thousands on new gear.

[MRK25T]

Inasnt,

Are you getting your powerFC through Nengun? I got mine a few weeks ago through him and cost me $1600 delivered. I put it in myself and then (as you know) got it tuned last saturday.

What do 550cc injectors cost to buy + install? I'm thinking of ruling out other stuff that could be wrong before spending more money. I guess ive spent about $10k sofar since I bought it less than a year ago.

What I dont understand is - why would the commander report that the injectors are at 72%. If there is a problem with my injectors wouldnt it read close to 100%?

Majanal,

I like to do things properly so I might have to get another AFM and injectors after I rule out other possible causes.

yep getting pfc through nengun for a bit cheaper than what u paid as its a second hand pfc and new handcontroller!

As for injectors the cheapest i have found is around $170 each for sard ones. I am getting all the parts together (around $7500) and getting it all installed at once.

We can high flow stock R33 injectors to 600-660cc capacity for $150 each. It’s all done on a flow bench and importantly all matched to one another so that all cylinders receive equal distribution. Removal and replacing would be another $200 but I’m sure a lot of you guys are good with the spanners and could do it yourselves

Btw, I have heard pinging on the dyno yet the power FC commander only showed a knock value of 27 and the engine check light didn’t come on. Go figure. Also Sydney kid has a valid point with the computer sometimes accessing the wrong load point in the tuning maps. So you might get an anomalous reading once in a while and the car might do funny things.

how long would it take to highflow 6 side feeds?

[T0nyGTSt]

At $150 apeice I would get new injectors.

Utasa, do u just drill them out? how is the spray pattern after u preform the op. I heard some very negative results outside of australia. Seems here people get away with it

we prob more advanced tho?

[MRK25T]

The above images are my dyno readouts after the tune. They include high and low boost graphs, AFR and boost on the Y axis.

Do they seem reasonable? I was hitting engine checklight probs at about 210hp,

Mark

[Steve]

MRK25T, those dynos look ok to me, nice result acutally. Have you checked your AFM peak voltage yet? The reason I ask is because that is exactly where mine hit 5.1v (max flow) when I first fit and tuned my power fc.

If your car is idling fine at 600 dont worry about it, I think stock is 660 rpm if my memory serves. If it isnt idling correctly, take it back to the guys that tuned it.

If you must mess with it, the idle is in the settings menu. Just remeber you may have to adjust the deceleration fuel cut recovery rpm first (setting above the idle setting), as you have to have at least 100 rpm between it and the idle.

[MRK25T]

I just checked it out a minute ago coming home from gfs place.

I tried it in 2nd gear and hit 5115 when the check engine light started to flash, I then backed off straight away.

Is this the 1.5v your talking about steve?

Mark

[Steve]

That is exactly what I am talking about! Now if you go into the etc menu (I think) you can disable the check engine light for the AFM. Take the car out again, and see if it still flashes. Alternately, check on your peak hold and it will show you what is maxing out, but I think this is the problem, esp as your injectors are less than 80% and you dont have any noticeable detonation.

5.1v (or 5.115v if you want to be exact) is max flow on the AFM = check engine light flashes.

[MRK25T]

So I need to upgrade my AFM to a z32?

I'll go outside to the car during my lunch break and see what it does when I disable the check light for AFM

Thanks Steve.
