put in my tuned pfc from srmotorsports. greddy smic. pfc is tuned at 12.5. i don't feel much difference from before with the stock ecu. might have a small vacumm leak b/c only boost to 10 up to 2nd and then goes up to 11-12 on 3rd to fifth. maybe i will feel more when i drop in my mp???? i have cb/intakes/dp/pfc and intercooler now. fuelpump and mp on its way in. any input is appreciated in advance. thanks.

 

One thing is that, although they did some rough tuning, the PFC is not tuned. No one can tune an ecu specifically for a car without having the car and a wideband. They can do a good job, but it won't be perfect. When you put in the MP you will feel a huge increase. Make sure to get the PFC retuned for the MP.

 

sorry bro, thats SR motorsports for ya...


how much did they charge for everything?

 

1150 for the tuned pfc. i already had the commander. the pfc is tuned for the mp also. nobody wants to put it on. might have to get some jackstands or a ramp to put it on myself. maybe that's my problem. the fooking cat.

 

If the PFC is tuned for a mp then it's running rich. If you added your mp then it will compensate for the extra fuel. I suggest you fine tune it to your specific mods. Tune it for 11.2 a/f ratio.

 

Installing the Midpipe will be pretty easy. (30mins.) Just do it yourself.

 

i agree with pcola.

you have NO idea what that ecu is really tuned for. they told you its tuned for 12.5 afr or whatever...yah..on their car.

xs tuned my ecu twice...i got so much detonation that i was close to sending them letters from my lawyer. YOU CAN NOT TUNE BY MAIL. period.

you will notice a difference up top with a midpipe but you will lose some low end torque.

just dropping in an ecu when you have the basic bolt ons will not give you a huge seat of the pants power increase...it will simply insure that you dont blow your car up. I noticed a difference after i did my streetport and tuned for fuel...but with bolt ons its not going to be a huge difference.

you should notice a bit of a difference with the IC. you will feel better flow and response in my experience.

it is possible that your cat is clogged.

get your car on a wideband asap. you are playing with fire by running a mp on an untuned car with higher than stock boost(what are you controlling boost with? I sure hope you are NOT using the pfc to do it). HONESTLY...i wouldnt even race around in it until you do get it on a wide band and see where you are actually at afr wise. I guarantee you that sr has no idea...and neither do you. they told you that to sell it to you...simple as that.

if the pfc is tuned to 12.5 then you are actually lean on their system. you need to be running 11.2:1 afrs throughout...leaner at vacuum and maybe a bit richer up top. 12.5 is agressive and probably not smart on pump gas.

good luck...have some patience. do it right or motor bye bye.

PS..I dont know about you guys but Im tired of the tuning shops like xs and sr selling thier bullshit mail maps. they are not accurate AT ALL and are not worth losing your motor over. the age of these cars and the problems and situations associated with each individual one makes tuning by guesswork...i mean by mail...impossible. its a crapshoot. I hope one day that those friggen shops take it up the ying for selling that crap.

 

from most people's experience, the SR maps are tuned VERY RICH. I am guessing you are hitting an A/F ratio well below 10:1 once you start boosting. This will greatly reduce your power.

(Artguy, I think he meant the PFC was tuned to 12.5 psi, not 12.5 A/F ratio.)

Get to a dyno and wideband that thing very soon. You can probably take out a LOT of fuel, even after you get the midpipe put on.

do what the others said and tune for low 11:1s at WOT.

 

get a pettit ecu and drive happy

 

the pettit wont do you any better...its still got to be tuned on a dyno.

sorry bout the number misunderstanding above...regardless it needs to be tune to the proper afr ratios on a dyno. timing needs to be tuned as well.

tuning by mail blows...pettit...sr...and everyone else. it has to be done on a dyno or you are FLYING blind.

good luck guys

1150, is way to much to spend on just the PFC, ecu. SRMOTORSPORTS is the worst place to buy anything from they are over priced, and do not ship anything in a timely manor. My friend bought a tuned ECU from srmotorsports and his car is running so rich, any time he steps on the gas black smoke pours out his exhaust.

 

aren't you worried about boost creep with running a mid pipe? depending on your exhaust you'll have to shove the silencer back in (the ugly butt plug) to get rid of the creep. or pull your turbos and get the wastegate ported.

 

I recieved my PFC from SR motorsports and everything was great. The PFC was a little rich but that was fixed with the datalogit (highly recommended if you have the PFC).

I got all my parts in a timely fashion from SR and they're customer support has always been great for me.

 

correct me if I'm wrong but just getting an upgraded ECU won't gain any power. The power is from you turning up the boost. The ECU just makes it safe to turn up the boost. If you're running the same psi as when you had the stock ECU, your car will be slower since it's now making your car run rich, which is safer than running on the edge of lean although running on the edge of lean made more power. But with an upgraded IC I could see you gaining some power but not much. Installing that MP and I can see lots more power in your future.

When I bought my pfc, I ran a safe 10psi at first, same as what I ran on my stock ECU. The car felt exactly the same if not slower. The car did idle allot smoother but I felt nothing I would pay $1000 for. Then I added a high flow cat, FMIC, intake, CB, and ran it at 14psi. Needless to say I had a nice grin on my face for days.

 

I would never buy a PFC from SR for the reasons stated above. It makes more sense to buy one from a discount place and spend the extra money dyno tuning.

That said I had a good experience buying a clutch/flywheel kit from SR last year. It was cheap and everything shipped out when they said it would.

wow. thanks for the input guys. i bought the tuned pfc as a temporary fix until i can get to a tuning shop. i will go to reactive racing but d said that sr numbers are pretty close to the numbers he get with the wideband??? will have it tuned anyways once i drop the midpipe in. i think the cat is clogged also. i am also adding a cosmo pump and a profec b sitting in my room once i search how to put one on. for now the pfc will control boost. thanks dudes. wish me luck

 

You're wrong.

I dynoed my close to stock car a few months ago. I have a downpipe and cat-back on the stock ecu. I ran an A/F ratio below 10:1 from 5k to 7.5k and below 11:1 from 4k to redline. This was measured with a tailpipe sniffer, so the car was probably actually running richer than that.

With a stand-alone ecu, I could take out fuel from that whole rpm range up to 11.2:1 or so and would probably gain 10-15 hp. Maybe more. It's true that it is not a large gain.

 

maybe he should have said you need to tune your ecu for your vehicles needs in order to gain any power.



however small that is...

No, what I meant was the stock ECU runs leaner than the pfc. If you run rich on your stock ecu, you will run even richer with the pfc. I think apex said the pfc is tuned with it's base maps for intake, cb, dp, and high flow cat for 12psi. Obviously, that should run really rich on a stock FD. Even with intake, cb, mp, fmic, at 14psi I was still running alittle rich. So basiclly what I'm saying is if you think just adding the pfc is going to gain hp, your probably going to have to get more parts in and turn up the boost. Oh, and get it tuned for maximum hp

 

Take the car to KDR. Ray can't tune a weed eater. He charged my brother to dyno tune etc. I drove the car and could tell he lied about tuning it or he didn't know how. We drove the car 7 hours to XS and sure enough it wasn't tuned worth a shi#. Eric tuned the car and did a FANTASTIC job. Stay away from Ray and his clown operation..

 

thats funny...Id say the same bout xs...their shop is full of clowns and their shop tuned my pfc like ***. granted eric is a smart guy...the other guys i dealt with there didnt know their head from their rectum.

dont bother with xs...and any similar bs shop that is tuning your car (which they dont give a damn about) ...just tune the thing yourself using the datalogit and a wideband. that is the only way you will really get it done right.

I wont ever trust them again. at least ray's tuning doesnt cause HUGE detonation. xs will blow yer ***** up.

does xs even have a dyno in there shop? I don't remember seeing on there

 

I recommend getting an FJO wideband to monitor your A/Fs ALL the time.. in REAL time!

Tune it yourself on the street. I agree... without knowin what the A/Fs are.. you're flying blind... and rolling the dice with your motors.
