Datalogit with FJO output
Hi guys...loooking into fine tuning my FD to run up to 17-17.5psi(1.15kg/cm2) which is the limit of Mazda map sensor.
I now have the FJO analog output connected to the AN1 input of datalogit and Polynomial setup entered as a=.3489, b=1.582, c=8.5401.....
A/F does not match at all with FJO monitor...off by 1 point. Am I missing something here???
Any help is appreciated
thanks

I have not seen more than 16.8Psi out of the stock map sensor.
You may have a floating ground issue with the FJO. We did with the TechEdge unit. Check the voltage coming into the Datalogit (raw voltage) and check the ground too.

thanks guys
my map sensor maxes out between 17-17.5psi....tested it vs difference boost gauges(HKS...)
@17psi its hitting 1.12-1.13kg/cm2.
@16psi " "" 1.06-1.07kg/cm2.
I may just datalog the A/F with FJO software and tune it taht way.
Thanks again

John,
You dataloging your boost gauges? Cool. Or you running a digi boost gauge with peak recall?
To tell you the truth, I've always used the PFC reading...since it's being logged anyway. Check your logs when you think you were at 17+PSI and check what the PFC says. Betting even money you're below 17psi...even with rough rounding.
Is your delta a constant "1 point?" Or is it a variation?
Smells like a ground problem still. Logging AFR directly is always an option, sure. Sure be nice to have it all in one place, though.

Badog: No, I don't datalog my gauges.....I knew the PowerFC boost numbers were a bit off and I just tested it with a pressure pump vs other guages(HKS) and these were the rusults:
PSI= kg/cm2
2=.10
4=.25
5=.31
6=.39
8=.51
10=.65
12=.78
14=.92
15=.99
16=1.06
17=1.13
~17.5=1.15 >> which is max for stock map sensor
PowerFC hits 1.15kg/cm2 somewhere above 17psi and will not register any higher.
As far as the wideband.....gonna datalog it with the FJO software and also have the big A/F display.
thanks

What's the resolution to the floating ground problem? I remember the thread, but it was way to technical for me. There was some sort of correction added to the software, right?
My FJO numbers are off, as well, but I've got the unit grounded to the ECU ground, so I didn't think any variance could be the issue...

If you want, you can send me your FJO and I'll figure out what is need to dial it in and compare it / log it in tandem to the TE unit. I was meaning to get another bung in my DP, anways!
Did you post about this on the Datalogit group too? I thought there were at least a couple who had done this already. But then again, before Kevin, Kevin, Kyle and I tracked down the floating ground problem, no one really noticed it much.

Then there is signal drop issue when you have the display plugged in and are logging to the PFC. That involved a soldering gun on the older boxes. New ones are SOLID (a-okay).
#10
Signal drop meaning when you have the FJO display plugged in, the voltage read by the Datalogit will be lower than it otherwise would be?
So if my problem is not floating ground (I don't _think_ it is, but I'm not sure), if I just unplug the FJO display the Datalogit may get proper values? Except, of course, then I've got no way to know what the FJO thinks proper values are in order to compare them with the Datalogit... I wonder if they'd consider using the serial interface the FJO exposes...
The fix for this signal drop is to the Datalogit box? How old is old? I was part of the second batch of units sent out way back in the beginning of time.

The floating ground issues were from 9/1/2002. If you can't find it in the archive in the yahoo groups I can send them to you, not that that would help much
Maybe this might help:

Signal "altercation" I should say. I don't remember off hand if which way the signal deviated. I could look it up. I might, if it would help.
Do you have a voltmeter? That is how we figured out things were not right. Try putting that in the "stream" with car off, but IGN on. Test coming out of the WB, then plug into the datalogit with it still tapped in, check again, then add the FJO display, check again. With the car not running, but IGN on, you should get some steady volts? Then try it with car at idle.
Let me know.

What I have noticed is that between 10.5 and 11.2 on the FJO display , my FJO display reads 0.3-0.4 AFR higher than my datalog. At around 12.0, it is more like 0.5 to 0.6 higher. It's hard to monitor this while driving but it's what I've noticed at low speeds and idle.
I have the FJO software but really haven't used it since I got my datalogit. My dream was to use the MAP Watch feature and I'm doing that with an on the fly adjustment of 0.3 to 0.6 in the back of my head and keeping an eye on the max knock sensor values as a 2nd check.

Just to be clear, are you using the delta function with the FJO connected to AN1 and AN2, and you still have a difference in readings? That's the way I hooked mine up last night, but I haven't been able to try it out yet. I should have the exhaust changed out today, and I'll be able to start testing tomorrow.
Cheers,
Rusty

Greetings all,
I got my Datalogit and FJO up and running today, and did some testing. As feared, the Datalogit readout is not close enough to the FJO display to suit me.
The analog out voltage goes to AN1, and analog out ground goes to AN2. When looking at the raw voltages, AN2 is almost always 0.00V. Maybe it was .06V once for a split second, but for the most part, the delta function doesn't seem to be needed with the FJO.
I started out using the polynomial that was posted (.3489/1.582/8.5401), along with the delta feature. This typically gives Datalogit AFR readings that are about .6 lower than the FJO display (FJO=12.0, DL=11.4)
For fun, I tried entering a couple points from 11 to 13 from the FJO graph, and that gave Datalogit AFR readings that were about .5 below the FJO display (FJO=12.0, DL=11.5). In other words, very similar to the polynomial.
Next, I set it up with the polynomial again, and collected some data. BTW, this was all done in my garage, probably to the horror of our new neighbors who just moved in. I haven't even met them, but they already know the car :-) To collect usable numbers, I set the laptop next to the FJO display, with a large display for AFR (AN1-AN2), AN1 raw, and AN2 raw. I used my video recorder to record the displays for later playback. To be a valid number, the display had to be stable enough for the Datalogit to update while the FJO was on the same reading. Unfortunately, the best I could do, was to collect data in the 11.4 to 12.0 area. Here are the data points that I was able to collect (AN2 was always zero):
FJO / AN1
11.4 / 1.16
11.5 / 1.22
11.8 / 1.31
11.9 / 1.39
12.0 / 1.41
If you look up the AFR values on the FJO supplied graph, you'll note that these voltages average .2V lower than what the chart says they should be. If I assume that the FJO display is correct, then either the graph is wrong, or the voltage being read is wrong. Either way, if a new polynomial is made by replotting the FJO curve .2V lower than on the the FJO supplied graph, it might just work out pretty well. I'll try to make this new polynomial tomorrow, unless someone who's more Excel friendly wants to do it for me :-)
Unfortunately, I won't be able to do any real testing for a few days, since I've noticed that my oil pressure is dropping dangerously low at idle. I'm sure I have good oil pressure, because it leaks at every possible orifice, but I won't run it again until the new sender I ordered arrives.

Very nice info, but where were you a couple hours ago when I was trying to get these numbers off the graph
I was initially hoping that these numbers were going to be .2V lower than what I was getting from the graph, but that isn't the case. I wonder where the .2V is going. Does the Datalogit have a high impedence input, or is there a chance that it's pulling down the analog output of the FJO? If it pulls down the output, is the FJO display still correct? I may have to ask a couple questions to FJO.
What I really need now is an Excel tutor, but I haven't given up yet. I also imagine that you could enter two points on a line from 10 to 13 and have a perfectly usable tuning range.
Happy holidays,
Rusty

Wouldn't you know, I screwed up uploading my changes and uploaded the default map. I thought I had blown my engine/turbos at one point. I freaked. Thank god I realized what I did. I didn;'t realize how extensive my tuning has been until now..

What do you need, Rusty? You need a poly for the values?

What I need is the last few hours of my life back Thanks, I think I figured it out finally.
I used the supplied values from FJO, for a range of 10 to 14.4, in .2 AFR increments. I subtracted .2V from each voltage that was given by FJO, since that's what I seem to be seeing on my Datalogit display. The result is the attached (if the forum will let me) spreadsheet, which seems to result in a polynomial of:
A: -.0006
B: +.0878
C: +.5144
Can someone try this out? David ?? My car's down until I get a new oil pressure sender, but I should be able to try it by the weekend if UPS makes it here on schedule.
Cheers,
