My car has a catback, intake, smic, dp, ast, radiator and that is all. Is it necessary for me to pick up a PFC as a means of engine management or am I okay the way the car is. I don't want to shell out an extra $1000 if the car is safe the way it is. Thanks for your advice in advance.

As long as your boost is 10 psi, you are fine and don't need to buy anything. If you are getting higher levels of boost or spiking above 10 psi, then you will need a boost controller -- manual or electronic. You can make a manual one for under $30.

if you add a mp, that would push it, or you could just upgrade the fuel pump to be on the safe side.

Thanks rynberg, looks like I will get a boost controller and set it at 10 psi, any recommendations on a boost controller? I would probably go for an electronic one. Thanks again

rynberg

Upgrading the fuel pump in his case wouldn't do jack ****.

I strongly recommend the "new" Profec Type-S for an electronic one. Simple to use and set, has two different boost settings (plus "off" for 7 psi), works well with the seq twins, and is very reliable. And it's also one of the cheapest on the market.

What are your current boost readings? If you don't know, then I strongly suggest picking up a boost gauge ASAP.

The nice thing about getting a boost controller now is that you could pick up a used Pettit/M2 ecu later on and run 12-13 psi pretty safely and enjoy a lot more power. If you ever want to upgrade the car further, you could sell the Pettit/M2 ecu for the same price you paid for it....

Thanks Rynberg, just saved me some $$, those are going to be my mods for quite awhile, just wanted a nice weekend car

buy my Pettit ECU and you can run 13 psi (with a manual boost controller)

$425 shipped

Of course, if you got the Apex'I PFC your car would run much better. It gets rid of all the pauses, burps, etc. of the stock ECU (hesitations). It also allows you to add the Commander to monitor 8 readings at once, and you can also add the Datalogit and your laptop to monitor just about everything and adjust most of it - on the fly.

A matter of what you want, of course. I think the PFC was the best "mod." I ever did to my car - best bang for the buck so to speak!

Rx-7_Enthusiast

hmm your rave about the pfc and how good it is causes me to reconsider purchasing it.

About the ebc, right now the car is 11-9-11, If I set the car at 10 psi, would it revert back to 10-8-10?

TwinTriangles

I have also said this many, many times. Getting a stand alone is the best "mod" you could do to your car as it then prepares you for ANY mod to be done in the future.

standalone = insurance = more power lol you should be ok like rynberg said but youre like at the edge of needing some kind of engine manegment

PFC is the greatest upgrade i have.
PFC w/o commander setting for every bolt-on's $650

NuTbAgSaN

ahhhh where from?? i want...

i have apexi intake + just a catback and i get 11psi...i havnt had spiking or any problems though. and i dont want to take any chance i want to get this done and a boost controller...i dont know about a power fc myself

You can get a brand new PFC with commander from Japan for $795 + shipping.

David Beale

Let me "take back" just a little of the enthusiasm read into my post. There is a "drawback" to getting the PFC. It's powerful, and you may have to do some setting of parameters - so if you're afraid of messing with this stuff, it's not for you. You also have to disconnect three pins - I removed them inside the PFC rather than cut wires on my car.

On the plus side, it will control your boost, and just about everything else on the car, if you want it to. When you add the datalogit you can even set what temp. the fans come on!

With the PFC installed I fell in love with my car again. No jurks and stumbles

How easy is the pfc to tune. When you install the pfc, is everything the same as before and you have to tune it to get all the things worked out? Or does it self-adjust its self to your set-up? Just curious I need to doa 5 sp swap befoe I can put in the pfc anyways.

For those debating on getting a PFC talk to someone locally with an FD that has one and have them show it to you. The PFC is a far superior ecu than the stock ecu because it has double the amount of processor ability and its fully adjustable. For people who are not inclined to changing parameters themselves, get together with a bunch of people locally and have Steve Kan come and tune it.

I have had mine installed for 3-4 weeks now and my car has never run better. The Pettit and the M2 units are nice alternatives if you simply do not want to tune your car or are a great distance from someone who can.

DO NOT TOUCH YOUR PFC


pay someone to do it. unless u like purchasing engines.

but PFCs come with a "base map" right?

and you can always go back to it if you mess up your "own" tuning program right?

potatochobit

NO

base map is for DRIVING the car onto a dyno or going to buy cigarettes before tuning. u could drive it at low speeds to and from work but it is not designed to have high boost loads on it.

rynberg

I think that's a little paranoid....the PFC base map is fine for 10 psi with bolt-ons. Ported motors or more advanced mods definitely do require fuel/ignition tuning.
Other than strict fuel/ignition maps, there are many other tunable aspects of the car's operation that may need adjusting, some of which are only accessable via the datalogit.

David Beale

Also, the base map mine came with ran at 12 PSI (with no problems). I turned the boost down a bit, as pump gas is not getting any better these days, and I'm not interested in adding octane boost. Besides, at 10 PSI my car is faster than any public road -I- know of!

2ZZ-GE

I was told the base map with 1200 cc injectors will be pig rich, even with BNR turbos....true?

Rx-7_Enthusiast

Well there have been nothing but compliments regarding the PFC, so I jumped the gun and picked one up. Now since the PFC controls boost, would I still need an ebc? I want to set the car at 10 psi and my good friend told me that many boost controllers can't do that because they can't lower boost. He has an AVC-R and he said it bleeds to control boost.

I believe the stock injectors and stock fuel pump should be fine with my modifications......hopefully......dp, cb, ic, pfc, intake, and all at 10psi

Also, I need some good recommendations on boost, water temp, and oil pressure guages. I am looking to get 52mm guages.


Looking to get that particular guage pod as it looks really tasteful.

Thanks for everyone's help thus far!
