some pics of stuff.
The FC Tweak is picky about data QUALITY, which is kind of a double edged sword. you get better results, but sometimes its hard to get an old car to have better signal...
on mine i got to skip the voltage being erratic, but the O2 sensor was noisy. after some screwing around, i mounted the wideband unit right on the Datalogger, and i twisted the wires, wrapped them in foil (matches my hat!), and used a shielded ground cable, which worked.
it lived up under the dash on two unused tabs, not sure why my thumb is so shiny
and looked awful, although one of the goals was to have this so i could move from car to car easily, and it worked, ~10 minutes to pull the thing out
the previous, and future setups have the Wideband thing on a bracket i made that bolts to the top center of the dash.
you'd think this would be a great place to have it, and it would be easy to see while driving, but its not
do i sense personal trauma here? maybe there's a support group???
lol, there is a google group, which is actually really good.
its just hard to get windows to see a cable, and this box, and then that all needs to talk to the PFC, and then to do tuning there is another piece of software....
and then once its tuned you need to reverse all that.
when it works it works, and you don't want to touch it!
i had all day Saturday to mount the DL-340XB box, so i enjoyed myself and took some pics.
First is where to mount the thing.
there was a FEED built FC that came up for sale a long time ago, and it had an F-Con on the kick panel,
Awesome
not awesome
and yes mini m&m's fit in the JDM flare holder
i looked at the glove box too, which i think would be best,
but with the cables, its kind of long and would require lots of cutting, and then where would i keep my gloves?
under the dash would work too, like the old box, but i'd need to make a new bracket
I apologize as I've been absent from this thread for a bit, but why stay with the antiquated electronics?
the PFC? there are a few reasons, none of which are really all that logical, lol
the tuning software, FC-Tweak is really awesome, its really unlocked features that the PFC had the whole time and nobody really knew about.
also i need to smog this thing still, and so i need to keep the Air pump, ACV, injectors, and ECU, although i can put the stock ECU lid on the PFC

Ah, gotcha. Well, to each their own. Good progress so far!
here is a screen shot of the playback screen in the new DL-340 box, so far this is the really big leap.
this is a 1st and second gear run from a stop, the AFR syncs up really well, but you can see that peak boost (green) is highest after i let off the throttle (yellow), its just interesting to see the time lags
its small, but you can also see the turbo come on boost, the wastegate makes it flat for a bit, and then boost creep takes over, lol.
not a great boost curve, its a little lazy and then comes on hard at 5500. i could fix some of it, but hooking up the boost solenoid (i need a vacuum tee, preferably not plastic)
and then you can also see a little of the weird stuff, something hasn't been quite right for a while, but you can actually SEE that the timing is doing weird stuff at low throttle openings.
i'm really not sure WTF would cause that, i can look at any of the stuff on the left side, and none really correlate, so possibly a bad connection.
Does the tweak-it datalog offer chart unit points? It would be helpful to see what's actually going on in the data log, in terms of actual numbers.
the data on the side is what is feeding the graph, so sort of. i can move the cursor, and it'll display the values on the side.
i can also change it to two or one graph, so i could have like TPS and Boost on the same chart
so far i'm happy with that, although i'm going suggest that i could full screen the chart, just to post pics
