The next version will have dockable and floatable monitor windows.

The advantage of the dockable channel window is that you can watch the sensor values while changing the settings. On a 1024x768 laptop this was never possible with FC Edit.

When will you have the latest version for download?

Thanks

FastHatch

Maybe monday, but i still have a long to do list with features for the next release, so i guess end of next week.

First of all,I have to say my hat is off for what u've done mate...really.
That's defo what I call state of the art reverse engineering.

I want you to know that if you need some help to process to the tests,you can ask,I'll be happy to help.I own a 430bhp Nissan Sunny GTIR (11.5s@125mph) and I've done all the mapping by myself,using of course,the FC Edit and the Datalogit box.I know the PFC and the FC Edit quite well by now,and I also tune PFCs for friends (running S14 Silvias,Subarus,etc...).

I've just downloaded the latest version available and I have two questions about it:

I/ I'm at work at the mo' and I have FC Edit on my desktop (even if I also use Excel to modify my maps,just to make people think this is real work!! lol ) and of course all the maps and logs that I've done so far.I tried to open one of my map (.dat file) with FC Tune and it didn't work. Do I have to read my PFC with FC Tune to be able to read my maps?(if so,I'll test it this week-end)

II/ Is it possible to open a FC Edit log file (.dat) with FC Tune,without having previously read the PFC with FC Tune?

In this thread,you asked people to tell you what kind of options they want to find in FC Tune.Here is what I'd like to have:
- more than 5 MAF choice available (or at least being able to define the V vs airflow curve we want)

- choice between a lot of injectors (with flow rate and lag already predefined: it would help beginers)

- the ability to log just the data we want and not all the advcanced stuff like in the FC Edit: I don't care about ignition timing (because not adjustable anyway), boost duty (I run an AVCR), air temp (run a MAF),etc...but with FC Edit I have to log all those stuff I don't personaly need

- something like the "Map Watch" mode of the FC Edit:it kicks ***.It's so easy to see which cell has to be changed with this mode!!(of course the whole map has to be displayed on the screen,using arrows to move from left to right won't allow to see how things change through the whole rev and load range)

- analog inputs: 0-5V AND type K thermocouple inputs. Datalogit box only has 0-5V inputs and I have to made a little circuit to turn my thermocouple signal (few millivolts) to a readable 0-5V signal...Cause the temp before the turbine inlet is really something that has to be monitored

- the ability to hear the signal which comes from the knock sensor, with a tunable high pass filter: if you plug earphones directly on a knock sensor you'll be able to hear knock quite well...but if you only hear frequencies above 2kHz,then it will be even easier to hear knock. That's why I'd like the FC Tune (and maybe FC Tune box) to allow user to hear the signal coming from the knock sensor,through earphones plugged into the earphone output of the laptop.

- a real boost controler,with the same versatility as an AVCR,not like the PFC boost controler which is pretty useless

- launch control!!! And a working one,not like the one from NZ... Something which would retard ignition by X degrees and overfuel by Y factor (or Y extra ms for injector pulse) until the car hits Z mph. Antilag stuff through a clutch switch could be usefull too...

By the way,can you explain what is the calculation done by the PFC to give the knock level?? Cause at the end of the day it's known that going above 40ish is rather dangerous but I'd like to know what the figure stands for...


Last question,but this time it's for all you rotary addicts: what the hell is those leading and trailing things??? I know it may sounds dumb question for you,but I just don't know rotary engine really well...and of course have never tuned Rx7s...

Thx for what u do FastHatch. (BTW,what is your car?cause you name tends to make me think you don't run a RX7...)

FastHatch

Bon jour!

FC Edit data files (.dat) can be opened with FC Tune, but not all PFC models are supported yet.


I have this on my to do list but i couldn't find lag time vs. battery voltage charts for the common injectors. Even on the data sheet for my RC injectors is only the flow rate, not the lag time.


The PFC only allows to pull the data in blocks (basic, advanced etc.), not individual channels. But FC Tune will have a channel selection dialog where you can select only the desired channels.


Working on that, might be in the next release.


The stock coolant and air temperature sensors are K type thermocouple sensors too and usually they have a 0-5V output.


Not possible.


I have the AVCR too and i don't see me working on my own boost controller any time soon.


That's a feature the box will have, but i have to intensely test this. I've read about all the problems people have with the antilag feature of the datalogit box.


I don't know if the knock voltage and knock level is directly related, maybe the level is some type of trend.


Honda Civic, currently with an Integra Type-R engine, but soon with a 2 Liter block and a GT35R.

Speak french? (I personaly dont speak german at all,sorry)


RNN14 (Sunny GTIR) Power FC is one of those "special" version done by Apex Engineering.Do you think I'll be able to read the PFC with FC Tune through the datalogit box?


I have a table with flow rate and lag time of several injectors (Nissan,Sard,Nismo...).I have to remember where it is saved on my HDD but if I find it,do u want me to email it to u?


Great!


Cool,cause it's defo the feature I prefer on the FC Edit.


I have the Volt vs temp table for type K thermocouple if you want...so that you'll see it's a matter of millivolts...
Coolant sensors and air temp sensors work in a different way thermocouples do.





Nevermind,I'll keep my AVCR too...


Yeah,this feature is really one of the key feature for me...and when I hooked up my clutch swith and tested it,I was quite disappointed to see it was not working! Of course I had a quarter mile event scheduled two weeks later...


You can't see where the knock level comes from by doing all the massive reverse engineering you're currently doing?It is not a software side you're studying?


Why not a turbocharged H22? Actually you curently own a track day toy,and you want to turn it into a quarter mile killer...

FastHatch

Could you email me a .dat file or scan (ECU/Scan) your PFC or just post your PFC model and version?


Ma adresse de E-mail est: andre at fctune dot com

I only have the tables for the Honda ECT and IAT sensors, would be great if you could email me the other tables.


I have only reverse engineered the interface and data structures, i would have to disassemble the firmware of the PFC to understand the calculation of the knock level. I might do this later, but this is very time consuming.


???


The H22 has too much stroke and weak sleeves (even resleeved), i've bought a Dart tall deck block (= longer rods = better r/s ratio) with closed deck sleeves. This block can handle more than 1000 bhp.

Fasthatch when do you think you will have the box ready for sale? Will it be before the end of the year?

Cubes

Will there be a USB version of the cable?

Xeros

Anychance of having a map compare function and a label for the P and N rows in the tables?

Xeros

oh and 3d graphs...or is that too much to ask?

rotorbrain

am i missing something or is there no way to set up a wideband/aux input yet? i was running through it last night and couldnt find anywhere to setup for AFR reading or a place for a mapwatch type layout.

and yes. . . 3d graphs and compare options are a definate plus!!!

Having upgraded to the D-Jetro version for my Silvia motor, I'm running the optional 3 bar MAP sensor and the harness has provisions for directly controlling an aftermarket boost solenoid (hence, it's already halfway to being a Boost Control Kit). Since I already have the solenoid installed from a GReddy Profec Type S, I was considering wiring it to be controlled by the Power FC. You're recommending I just keep the Profec intact? The PFC's self-learning and 4 preset features sound promising, but does it just not work correctly?

An easier implementation would be a two-step launch control. With the clutch pedal depressed, the rev limit would be set to something lower than the actual operating rev limit, thus allowing the driver to launch at WOT. The AEM EMS has this feature.

Actually, after studying the Nissan systems quite closely, 60 is the M.I.L. threshold. Anything below that (20s thru 50s) is considered normal operating knock range.



I'm looking forward to the release of Fasthatch's dongle box. I work for an anonymous Power Excel shop with a Dynapack (awesome tuning tool!) and I'm preferring this over A'PEXi's in-house tools. I'd love to participate in some sort of beta testing ... I just can't wait to get my hands on one of these babies

Fasthatch,
Also wanting to know how the box is coming along. Are you still planning on producing one and if so what kind of timing? You haven't really commented on it in a while, when people have asked about its release and timing?

Thanks

FastHatch

Map watch is about 50% implemented and should be in the next release.


Already on my to do list, but 3d graphs have no priority, 2d graphs are already implemented. Just have to check scaling etc. for every setting.

FastHatch

Not sure what you mean with P and N labels, you want to switch between N1..N20 and the RPM values for the axis?

FastHatch

Maybe later, you'll have to use a Serial/USB converter if you don't have a serial port.

FastHatch

I'll test different versions of a 2-step rev limiter next week, but a 2-step is not the same as an anti lag feature.

I'll test one version with a clutch pedal switch and one which monitors the vehicle speed. If the last one works as good as the first one i don't see the need for an extra clutch pedal switch.

FastHatch

I don't think the box will be for sale before the end of the year, but i ship out some test boxes next month.

Please understand that all PFC models and versions have to be supported and tested as well as the features. The dialogs to set up the box will be in one of the next versions of FC Tune and most features are also built in into FC Tune so they can be tested with a laptop or handheld.

Xeros

Yes, for example when I am lookign at the datalogit and I read the forums and peoples advice on what cells to modify they alwasy talk in P and N values making it very easy to hunt down the cell. Or even a cell hunter! Such as a box to type in the rows you need hit eneter and boom you have the cell. instead of hunt point and trace with your finger on the screen, making tuning a quicker easier process. Even a boost vs rpm label would be nice too when tuning the A/F....

FastHatch

Are the map watch icons self explaining? Any better ideas?

Hi FastHatch, i have been watching this thread with great interest.
Just a couple of quick questions .
1)is there a Nissan R33 GTST (power fc) version available yet.
2)Same for SR20 S15.
3) will the box be able to communicate with all makes Nissan Honda Mazda etc.

I am very interested in purchasing a box or several when they become available.
Could you provide a link to the latest software release.

Thanks zspanners.
