I am planning on purchasing the PowerFC, but can anyone here give me the details about it? Such as the features, functions, flexibility, pluses and minuses? The information on the PowerFC is scarce, and most of them are in Japanese!

I have some specific questions as well. Is the tuning format similar to the VAFC with the commander pad? Is the flexibility of tuning like the VAFC with only 8 points for low or high RPM? Can the PowerFC tune below 1000RPM, unlike the VAFC that can only tune above 1000RPM?

Feel free to add any more information that might help me out. Thanks

You should IM Austin...he will be able to help you out.

 

it's more flexible than VAFC. It can be tune below 1000rpm. It can tune in every 500rpm from 0-10000rpm. Things that can be tune like vtec point, ignition map, fuel map, injectors size, fuel enrichment for sudden acceleration, fuel enrichment for water temp.

 

this might help a little
its the manual for the RX7 power fc
the link is at the bottom of this page http://cc720821-a.bnapk1.occa.home.c...c/powerfc.html

Tony~

I've had mine for about 3 weeks now and love it! I'm still learning the functions, but the RX7 manual will help a lot. The ghost map trace function is the best feature for tuning in my opinion! You can record a particular acceleration and freeze all the cells used during that run. Correlate this to your a/f ratio and you have the exact fuel/ign cells that need to be adjusted. That is worth its weight in gold!

 

I'm thinking about a Power FC myself and more info would be appreciated.

How does the Power FC compare to the Hondata?

 

Tony

Give Kennedy HiFi a call in Scarborough. One of the customers there has the Power FC in his 2000 Type R with TODA B's and TODA header. I believe he was going to tune it last week. Ask for Alan(he's the owner), he should be able to put you in touch with the guy who has it in his car or maybe answer your questions.

Anselm

 

better than hondata, hands down.

 

I just picked one up without the manual from a friend. Trying to get it to work and I'm trying to reset everyhting to the defaults for the B16B version that Apex had in there. The initialize all data doesnt seem to do it and I'm trying it in my 97 Prelude but it wont start. Personally it sounds like the fuel pump isnt turning over, any ideas ? did oyu guys just purchase it and plug it into the car and started up ? or did oyu have to do some preadjustments before starting ?

thanks,
Greg

 

why?

 

SWEEEEEEEEEEET!

 

Interesting problem Greg...did it work before the PowerFC was plugged in, and did the PowerFC work before it was installed on the...Prelude? Are Honda ECUs similar enough for you to be able to use the ctr computer for a Prelude? Just asking questions...

my setup...
2001 itr
B18C PowerFC
Kenji Harness adapter

Everything just plugged in. Dan @ Godspeed did some minor tweaking with the ECU before he sent it to me, but when I finally installed the TODA B's I initialized the data so that I could start from the beginning...still playing with it. When you initialize the data, the data will stay the same until you turn the ignition OFF, then it will reset to the base maps again.
Hope that this helps,
Austin
P.S. When does John send you your parts?

 

From what i hear is that the commander doesnt have very many tuning parameters, and to fully capitalize on the Power FC's controls you must buy a DOS based program and tune with a laptop..the only problem is that in North America, XS engineering are the only people who are allowed to do this. And like me, you live in Toronto, so it's pretty hard to send ur car down to California to be tuned.

I'd look at the Haltech E6K. its what I purchased. go to http://www.haltech.com for more info.

 

THe only minus that I have found is that it does not have an active knock retard feature...but then again I have a J&S Safeguard, so it doesn't matter to me. THe other minus is that you do not have full datalogging, just a map trace feature...but it works for me. I love this thing...driving home last night and noticed that at very low rpm and a high load on the car the J&S was kicking in...put the map tracer on, found out where it was, and retarded the timing in the 5 cells that I was having trouble with, problem gone...changes all made in real time...also noticed that I was running very rich around 2000-3000rpm at part throttle, traced the maps, found the problem and fixed it all before I got home...you can also turn the O2 feedback off so that you can look at the actual A/F, without the ECU compensating...that is if you have an A/F meter.

The tuning is far more advanced than the VAFC...I couldn't handle working with a VAFC after tuning with the PowerFC. you have tuning points at 500rpm intervals from 500 rpm to 10,000rpm, and manifold pressure intervals...in total you have a 20X20 map for timing, and for fuel...though for a NA vehicle you only use 10-11 of the pressure points. If you are between a couple of the points the computer will interpolate the surrounding cells to figure out what the timing/fuel should be. There is a lot of flexibility and I love the thing.

So once you have a Power FC, a V-AFC is basically Useless right?

 

Correct...the VAFC is a childs toy compard to the PowerFC.
Austin

 

ok well i was looking into gettin a V-AFC pretty soon.. why not just get a POWER FC now, and save myself from having to remove/sell the V_AFC later... are theyre any downsides to running a POWER FC, with minnimal mods?

 

Thanks everyone! You guys made me set on purchasing the PowerFC. Give me a reason why I shouldn't buy it

I hit the search and read some of the older posts about tuning partial throttle. Is it true that the PowerFC can tune at every 10% throttle? Does that mean I can tune the entire revrange in 10 throttle ranges (10% each throttle range)?

Another question... is the PowerFC capable of having multiple settings? ie: conservative and all-out aggressive settings? Let's say conservative settings for everyday driving and aggressive settings for performance?

I remember reading somewhere that the PowerFC does not know how to adjust it's fuel and ignition as the intake pressure fluctuates? (ie: different altitudes and dramatic weather changes) Anyone finding that a major problem/weakness?

 

austin, yup thanks after someone posted the fd3s manual I saw it written there, lol thanks ...

I also have a feeling that the fuel pump is not set to ON there are 2 switches, fuel pump control and fuel pump operation, I'll check tonight when I get home. BTW, any goodies in the B16B manual thats different from the FD3S manual ? if so, I'd love a scan of those pages if possible.

John, is working away, I need to send him my exh temp bung to put onto the header.

Right now I'm basically trying to help my featured cars (like Lip, Incognito, Denis, etc.) to run this weekend ... all with the name GBR stickers on them

as for the features, I would spend the 1300 smacks on the new DFI, basically this unit does the same thing that the standalone units do with the exception that its plug-n-play. The datalogging/maptrace could be better, would be great if they had one for obd1 cars (maybe they do). Otherwise it looks easy enough (for me anyway) since all the setup features are similar to Haltech, Motec and DFI.

Greg,
There are a few differences between the RX-7 and the ctr manual...I'm waiting on someone to return them with the translations, as they came with the controller and were in Japanese. I don't have a scanner, so I had to send the a local friends family to have them translated.

 

How hard is it to learn how to tune the Power FC if I know nothing about the parameters in there. I mean how difficult is it to learn what all the parameters in there mean and how hard to know what to do with it?

 

It is not very hard to learn...but you do have to have some comon sense, because you have the ability to seriously screw up your motor if you don't know what you're doing...I've been playing with my PowerFC for the last 5 months and I think that I have a fairly good handle on it. If you would like the instruction manual for the RX-7 I can e-mail it to you, but it is about 1MB.
Austin

 

hey got a 96gsr power fc forsale drop on project need to sell it is brand new with the dataloger emai me at junitoway@aol.com
