AFR Datalog?

[ShelGame]

wowzer asked in the MP Tune thread, but I'm not sure if anyone really saw it - so, does anyone have a good WB AFR data log?

He's trying to create a somewhat automated PEFTBL re-calculator in MP Tune. It's basically done, but needs to be tested out.

Just need some data.

The data needs to have AFR, MAP, and RPM for each datapoint; at WOT if at all possible. Any number of data points would be good, but the more the better for tweaking the PEFTBL. Also, it would help to know what cal you're running so we can reference the correct stock PEFTBL.

The way it will work is, you input a table of AFR data (AFR, RPM, MAP), and MP Tune will draw a 'ghost' line on the PEFTBL that represents the changes required to hit the desired A/F called for in the WOT fuel table. All you have to do then is move the PEFTBL to the ghost line to correct the AFR to the desired AFR. It's not quite automatic, but it's a good start.

Wow, that's really cool. I'm willing to bet that there are quite a few datalogs out there with those in it.

The more the merrier

I anyone has a log they want to share, just post it up here. I'm sure morris will see this...

Rob aka Forcefedmopar should have all the logs you need.

Is there a spair input to use that the WB 4v could be wired to to log through the Smec
right now im logging through the smec/ snapon Solus and veiwing on shopconnect i can mae 15min movies at a time

I was going to put it into the NB input. Then, convert the signal internally (via a table) to simulate the NB signal. That way, I can log the WB data with MP Tune, but (theoretically) run like stock.

But, that doesn't exist yet, and won't help you out.

To answer your question directly - No, there's no spare 5v inputs to use for the WB signal.

How about the charge air temp? Assuming the cal isn't using that info, I don't see why one couldn't plug the WB into that input, then log everything at once?

Seems like the factory doesn't really do much with the charge air temp sensor anyway... Although I admit, putting the signal into the NB input would be ideal!

just saw this thread. thx for posting shelgame.

anybody? like shelgame said, its already setup in the latest version. unfortunately all i had for data were logs from my lc1 (POS!) off my camaro. haven't had time to hook up the ngk afx.

Bump for data!

I might be able to help here.
I use a TechEdge WB controller/datalogger that will log all that and more. It uses Winlog to log the info, and I also use a flashable smec so I could try stuff for you quickly.
I use a 3 bar map and 52lb injector's, but I can easily swap the 2 bar back in and turn the fuel pressure down to try and simulate stock injectors.
The van is built as a 2.5ltr Hybrid with a HY35 turbo, and is 5sp, which may be good for testing the pumpeff calculations as it is a fair change from stock.

How would you prefer the info? Would it be best as voltage or afr, psi etc?

That's great! AFR+RPM+MAP is what we need (and we need all 3 for each data point - ie, XX AFR @ YYrpm and ZZpsi). I think we would also need (for testing purposes) the TPS voltage. The calculator will compare to either the WOT or PT fuel table, but you don't want to use PT data against the WOT table, for example. So, we'll want to be able to separate the WOT and PT AFR data.

It doesn't really matter (I think) if it's stock, 3-bar, +40's etc. But, we would also need a copy of your cal to make it work right.

Im running a zietronix wb, is it alright to just log the voltage at the map sensor, or do you want it to be in actual psi readings, cause then I need to buy the boost pressure sensor and at a $100+ I don't see that happening.

That should work. I can convert it to the ECU MAP units...

voltage is fine for all the sensors. as rob said they can all be converted back to the appropriate units as needed. will need to have the cal that goes with it also.

I hope this helps, really don't know what I'm doing!! Let me know if it's not what you are after, and how I can help more.

My Zeitronic seems to crap out every time I make a full run. I'm not sure if it's a ground issue or what so I don't have may full runs. Here's one of the good ones I've gotten through all 4 gears. TPS shows 93 at wot on the datalog. It's in a CSV format also. This is my hybrid motor. Should be a variation of the cal a sent you a a while ago.

Same PEFTBL as the cal I have on file for you? Or have you tuned it?

[bfarroo]

I sent you a email with my current cal file.

If you're interested I can try and get one next weekend with logworks on my CSX. I'm not sure how easy it'll be to export whatever format logworks uses into something that you can parse automatically, since it doesn't spit out .csv files.
