FPR needed with PFC??

Postby KiwiMR2 » Tue Oct 04, 2005 12:07 pm

My Power FC has arrived :twisted:

I was told previously when I did my dyno run that to fix the running lean etc. an an aftermarket fuel pressure regulator would sort it....now that I have the Power FC I probably won't require that now aye??

with pfc u can run bigger injectors without the need to run such high pressures to get more fuel out of your old undersized injectors.

If you're keeping your ct20b, I don't think you should use an FPR.

I've been toying around with the idea of adding a FPR to my 550's to raise them from 531cc (lower MR2 pressure) to around 580's (if raised to around 50psi IIRC) before heading to dyno tune.

But I ain't shooting for mega power so I think that should be okay.

check what duty cycle you're running at first. keep an eye out on your knock. post results.

I plan on keeping the CT20b, I'd like to think the 540's would be able to keep up :)

I'll post the results......I might have a go at plugging it in tonight 8O

Well I plugged it in, car started fine so that was a good start 8)

I did the learning thing for 10 mins, then went for a bit of a blat to get gas. My 1st impressions are it doesn't really feel any different......possibly a tad smoother but not a great change. I was a bit hesitant to give it death so started on the low boost setting on my Profec. That was fine for 2 mins so I had a go on the high setting (around 16 psi) and again it seemed to be fine (but I didn't quite floor it to the max) and I get no check engine lights at any point of my journey.

I ran out of light so i couldn't run the commander into the cabin (what is the best route for this??) so unless it stores your last run data Im not really sure what it was reading, I had a bit of a fiddle but need to sit down and read the instructions (having a look now).

So yeah

I had to buy the APEX'i cable extension to have my Hand controller to be in the cabin. Or you can be like Wildcard and rangi one up from jaycar.

I used to run my 440's @ 90.2% injector cycle, at 1.01 kg/cm^2
I can feel the love already :) Ring your car out to redline and see if you reach 85%, that's the safe zone.

Cable tied to the air vent ;) but then again Ive never intended for the HC to be sitting in my car the whole time. After my tune is stable I'll be putting mine back in the cupboard.

I have checked the yank board last night.
If what they said was right, putting an FPR on our cars is a waste of time unless we upgrade the fuel pump.

Because our pump cannot maintain flow if the pressure is high.
I was JUST ABOUT to buy the aeromotive kit for our car, for $139 USD (includes all fitting), then I spent another 20 mins and checked that it's a waste of time.

And the Gen 2 fuel rail is crap too (so they say).

Hey what is controlling the boost when the pfc is plugged in?? I hit what felt like fuel cut while boosting in 5th gear on the motorway tonight, I didn't see a check engine light though :?: I had my profec on the normal hi setting (16 psi) but I was reading today that there is a certian level of boost control via the pfc.....even without the additional boost control kit?? Would the pfc be setting it to a certian level and then my profec trying to make it go higher??

If you buy the optional boost control kit, you can control the boost and do a lot of weird stuff with it.

When you hit what felt like a boost cut, did you check your peaks? The check engine light only flashes momentumly, you gotta check your peaks with the hand controller to know more.

Your Gen 3 sensor should go higher than 16psi, I know the gen 2 MAP sensor only goes upto 1.2kg/cm^2 before it spaz out.

Ok well again I tried boosting in 5th at 100 kph......it started to boost and bang, again what feels like fuel cut :? I checked the hc once home and it read my highest boost pressure as 1.03 kg/cm, that must be were I was stopped.

I noticed in the manual it says "When using a boost controller other than the power fc, be sure to set the power fc boost to a level where fuel cut will not occur"

It also says "If the boost rises 0.25 kg/cm over the preset boost levels, a fuel cut occur thereby notifying the user of a boost control problem"

remeber I haven't changed anything in the hand controller.....is there some "base map" setting that is limiting me from going over 1.03 kg/cm?
