Well i've had my fc datalogit for a few days now(cheers mate
) 8)
So I thought i'd start a thread as to how i'm getting on with it and to see how others who have it are getting on :?:
Anyway first thing to do was install it on the car which is simple enough just unplug the commander from the pfc and plug in the datalogit then if you wish to still use the commander (i use it to watch the knock levels while driving)then plug it into the datalogit.
Then its just a matter of connecting it to the laptop with the usb or serial connector (I have the usb) and loading the software or so I thought :roll:
I connected the usb to the laptop the laptop picked it up but couldn't find the driver for it :? lots of messing around later I found out the driver for it is on the floppy disc also supplied which is great if your laptop has a floppy drive :roll: mine doesn't and iirc most modern laptops don't either, so why stick it on a floppy ffs :roll:
So I stick the floppy in the desktop and it doesn't work :x alittle messing around again and it starts working 8) so how to get it from the pc to the lt, I decide to email the files to myself on another email addy
the files won't email :x I try various emails but they refuse to email :roll: so in the end I uploaded to files onto a online email address (yahoo) then swop back to the lt and get them back off the email and load them onto the lt 8) if they'd just stuck the drivers on the software disc in the first place this would have been much easier :roll:
So I load the software onto the pc(this has to be done manually) and try again to connect the datalogit hooray its works and finds the driver for the usb this time 8)
No manual comes with the datalogit so alittle more looking finds it on the software disc in pdf format all be it for a r33 skyline :roll: but everythings pretty much the same and you get the general idea
So I follow the instructions and "read all" setting etc on the pfc as it is and save incase I have to revert back to the original base map
this needs to be done as the default base map on the datalogit is for a S15 :? and is no use on the R, I deleted this default S15 map and replaced it with the gtir base map that came with the pfc to avoid any confusion later on, this base map had already been setup to use the z32 maf and sard 700cc injectors with the commander so I wouldn't need to mess around setting all that if I did need to reload the base map again.
So I spend some time looking through the features it has and like what I see as you can change just about everything and theres so much more than what can be accessed with the commander, the thing I find really good is in the map watch mode you can set it up so you can see the knock levels at every point on the 20/20 map allowing you to do a run then go back and check the map and see exactly whereabouts and at what load there is room for improvement 8) if you have a wideband afr meter with a external output this can also be used on the map watch so you can see exactly what the afr level is for every point on the map which simplifys tuning massivley 8) the antilag could also be pretty cool :twisted:
So with the aid of the R's knock sensor (supposed to be pretty good) a wideband afr gauge with datalogging and external output and a egt gauge I'm finally set up to go and have a play 8)
this is what my dash looks like at the moment lol

So with everything finally setup and working I go for a drive the first thing I found and all ready knew this from the commander was that the load scale on the map wasn't large enough so by 4000rpm the airflow had gone off the top of the 20/20 map which only reads to about 4v with the z32 maf this is of no use really as it means any airflow above 4v's has to be mapped with the 4v load line
this is a problem with the commander as you can't do anything about it but with the datalogit you can rescale the load settings to go all the way upto the z32's max output of 5.120v so I precede to rescale the load axis of the map to allow me to map for all the airflow i'm using, I then adjust all the fuel and ignition settings to match the new scale which has to be done otherwise you could have the 4v settings at 5.1v's which could leave you with massively over advanced ignition advance and dangerously lean fuelling :shock:
I use the compare function to compare the new map with the old one to make sure theres no major errors on my part, this shows up as either yellow map points for - settings and red for + settings 8)
Everything looks ok so I load the map onto the pfc and start the car
its runs like a bag of cr@p lol massively overfuelling and generally awful I try to take it for a short drive but return quickly as its hesitating badly etc
I swop back to the base map and all is ok again :? I call it a day at that point as the lt battery is dying at this point(3hrs bat life yeh right more like 1hr toshiba :roll: )
I then go back to the sofa and procede to compare the 2 maps again with the compare function(anything different shows up in either red or yellow) I can't see any problems, much head scratching later and I realise the airflow voltages have fuked up somehow and are all over the place the compare function didn't show this :? so I reset all the airflow points(32) to the correct voltages from the base map and everything looks good again
I play around with the maps alittle more making some more fine adjustments to the timing etc and save what i've done and relax on the sofa with a cool stella or 4
day 2 and I try again, I reload the new map onto the pfc and start her up again bingo alls working well this time so I go for a drive with the map watch watching the knock and me watching the afr meter on the dash for the fuelling (I also set the knock warning to 50 from 60 to give me more safety) I drive steadily and alls well so I give it some throttle in 5th (most load and slowest build up speed to aid logging) it gets upto 4000rpm then the engine management light flashes to warn me the knock as has gone over 50 (60's supposed to be safe limit) so I abort the run and check the map watch sure enough at load point 18/19 at 3600rpm i've got a knock level of 56 so I back the timing off 1 degree at each point and try again much better this time but still alittle high a few adjustments and all is well
time for another run with more revs I take it upto 5k rpm this time only to find its still going off the top of the map so I rescale the load axis again and try again, its now staying in the map and the knock levels under full load as now acceptable I call it a day again for now as the lt bats are dying again :roll: I save all the watches and logs to look at later and make adjustments to the map as required.
You'll notice I haven't messed with the fuelling yet as its safe at the moment at 14.5ish afr on cruise and high 10's low 11's under load and the egt temps haven't gone about 800 so i've left that for now to concentrate on the timing
I go for a bit longer drive to check the fuelling etc and alls well though i've only revved upto 5k rpm at the moment due to the new big ends in the engine :roll:
I'll update as I go along with the highs and lows of mapping with the datalogit 8)
Although I'm using the knock sensor to check for det and it seems to work well I need to make up a set of det cans to double check things, anybody made a set up :?: if so how did you do it, is it just a case of getting a set of ear defendings and drilling a hole in them then getting a length of rubber hose going to them from the engine bay :?: or is it more complicated than that as I can't find anything on the net about it :?
I've also ordered a car charger for the lt so I can spend longer than 45 mins playing lol
Hows everybody else getting on then :?:[/img]
