*disclaimer* I am not attempting to tune.... just curious... curious if there is a way to convert the measurements on the PFC to SAE not metric. Also I keep hearing about this selflearning... happens all internally??? no screen and no output??? thanks for any help and suggestions... one last thing, anyone know a good tuner in FL? I have searched the archives and PM'ed and such but looking for someone who actually cares about the car they build not the driver...
-coda
Installed PFC yesterday and idle smoothed right out even with defrost and lights. wooohoo! moving on up! cant wait to get it tuned to see the power gains after DP and IC... running only pettit intake, AST, and catback now. 93'
-C
I've also heard and am trying to join the upcoming steve KAN tuning session if it ever materializes here in cenFL. any other shops within driving?
thanks again.

The PFC is metric only. Learn to think in Metric - it's a damn shame the rest of the world has moved on and the US is looking like retards with the Olde English system. It's not hard at all to interpret the metric data.

Self learning? The PFC learns the idle, that's it. Everything else is tuning - it won't "learn" anything for the fuel maps.

I agree!

Did you know that for many years some American scholars want to modernize the American version of English. They want to get rid of the inconsistancies of spelling and pronounciation, but there are too many old died hards full of SH** that they can't see the benefit. Tradition just for tradition's sake is so retarded!

coda23

About tradition without question I agree.
As to thinking in metric... what can I say??? I'm a lemming.

When the speed limit signs say:
55mphX1.6=not enough KPH then I'll learn.

truth be told, if I want to keep using this PFC I'll learn.
I distinctly recall running across a webpage with the conversions listed... saves me from breaking out the physics book... which leads me to a question about your postscript...

recursivity is the nature of fractals AND conversions; i.e. converting PFC metric to SAE is celebrating the same star stuff that you spout off about as being the nature of the universe... so obviously you do not know about fractals; perchance do you even know what string theory is?

coda23

mebbe I should sail to merry olde england a grab that original standard meter stick and whack meself on the head with that 700 year old piece of brass? until either I learn metric or bash my head in?...
would I then satisfy your need to be so superior? most sites suck cause of insecure people like you.

coda23

no man is an island... so I dont know everything about the PFC... I ask for some help...
I know neither of your comments were directly confrontational but they sure smell bad. nice job of lending technical advice and suggestions... I'll now refrain from more directed comments myself but know...

no man is an island.

and that poem ends with,
it tolls for thee...

coda23

Well... I feel better.
Dale... you didnt say anyhting that I took offense to. I agree with you and was looking for a link to prepublished info...
cew... your comments may have been intended as neutral and general in their nature but they sure took a slant that I didnt care for...

I do not like to be insulted even indirectly when its uncalled for...
no one does.

The important part of fractals in relationship to creating the universe is like the butterfly affect in chaos theory where a very small change can end up resulting in a drastic large change. Look at the occurrances of fractals in all of the designs of our world. One day an egg and the next day something else. A minute change ends in a drastic change.

Then we have the idea of string theory in relationship to the creation of all the energy forms in the universe since matter is an imagination of our low/slow energy levels of existance.

Who gives a crap about the recursivity of language and the animal behavior of humans.

You need to get laid as you are wound way too tightly, and are interpretting ideas
that are not even directed towards you. If you read my entire post with an open mind, you would see it was slanted against our government and old fashioned intellectuals for being too traditional. Nothing about you learning or changing.

coda23

as to being wound tight... yeah... I'll give you that.
its the nature of the universe. some of us vibrate at a higher frequency than others... =] As to the insults you're right... but in my defense I see a lot of gaurded provincialism and indirect insults online here... I am not into passive aggressivism but more of the direct type. Could you tell?

Anyhow, I like both(cew/dale) of your posts as it seems you have significant experience and knowledge... I have followed several of Dale's projects and they have turned out sweet. Cew I heard you are one of several PFC gurus online... I am new to this and if my lack of polish makes people want to climb upon their high horse and show how smart they are then this isnt the place for me... I was merely asking for some shared insight into something I do not know about... the PFC not the metric system. I dont lose sleep over these posts so I'm not wound tooo tight... But in the same breath I also do not define myself by these posts... its hard to type eveything that one is thinking...
I can appreciate not wanting to answer every nonsensical question with a paragraph but , man, come on, where's the love? Do you not wave to other rx7's?
or is that too much animal behavior?

ANYHOW, back on topic .

People think that it's way hard to use metric measurements, that you have to do the math in your head. You don't.

For example, the first time you ever saw an RX-7 and someone tells you it has 10psi of boost stock, guess what? That meant NOTHING to you. Is 10psi a lot? Is that good?

Over time, you realized that 10psi is stock, 14psi is a lot more fun, etc. and you learned to think in PSI. Now, if you start thinking .7 kpa is stock, 1.0 kpa is like 14psi, so that's a lot - hey, you're thinking metric.

Temps are even easier. 100 deg. celcius is boiling point of water, and is getting too hot. 82 degress C is the temp the thermostat opens at. So, if you're cruising at 82 deg. C, you know your 7 is nice and cool and at operating temp. If you see 110 deg. C, hey, you're overheating, shut it down.

Takes very little time to recognize what values are "normal", what's "too low", and what's dangerous. It doesn't matter if it's inches, hectares, BTU's, or bananas per second - once you get a "feel" for the values, you're fine.

I agree, if you know that 2.2lbs = 1kg, 1 bar is 14.5psi, 1mph = 1.6 kmph it just takes a bit of quick adjustments in your head to go from SAE to metric and back. Really you don't need to convert, but just "think" in metric or SAE. It's like learning a foreign language, if you grew up in the US and you become fluent in French/German/Russian you don't translate in your head. You just "think" in that language when you need to.

coda23

Dale I see what youre saying... also Y with the foreign language analogy... The temps are easy enough but I agree that 10PSI means nothing to me... especially as the PFC is measuring in metric... so I understand that 110C is overtemp no matter the antifreeze... just to verify the .7 is equivalent to 10psi and 1.0 equivalent to 14psi accurate? also what is no good on the stock fuel system I kept reading about detonation at 12psi??? or the fuel system not keeping up??? thanks for all your insights(not insults) keep 'em coming.

coda23

also reading the archives and other threads but having answers to questions you pose for yourself helps clarify the situation that much more... thanks guys.

This might help or make things more confusing:

1 ATM (atmospheric pressure) = 14.7psi
1 kg/ccm^2 = 14.22psi (used by the PFC)
1 BAR = 14.5 psi

KHPa = hector Pa/thousand; 1.0 KHPA = 1000.00 HPA = 14.5 PSI = 1 BAR (used by Blitz in their boost controllers)

These are the more common used for boost gauges.

thanks guys... dale hit it on the head with his rough approximations... some general knowledge was what I was looking for.... the conversion link gave me exact #'s... again thanks guys.
