Anyone care to look over my current tune?

[jpb1972]

The second picture is not quite right..

Clear everything out on that tab, then for the col(top) axis set the sensor to mass air flow frequency, unit to hz, then put these in for the labels.. Leave everything else blank on that page (should be same as you did for the fuel trim ones earlier)

1000,1150,1300,1450,1600,1750,1900,2050,2200,2350, 2500,2650,2800,2950,3100,3250,3400,3550,3700,3850, 4000,4150,4300,4450,4600,4750,4900,5050,5200,5350, 5500,5650,5800,6000,6200,6400,6600,6800,7000,7200, 7400,7600,7800,8000,8200,8400,8600,8800,9000,9200, 9400,9600,9800,10000,10200,10400,10600,10800,11000 ,11200,11400,11600,11800,12000,12200

Then add the AFRerror PID to the table display, same as you did with the MAF hz one a few days ago, and see what happens..

Finally have activity on the histogram now. My AFR PID is causing improper calculations in the table now. If I get the AFR error PID squared away it should be good. Even tried building my own PID parameters for a new AFR PID but it's not right. The AFR error PID still disappears within the table, like its unsupported, soon as I open a log file.

Ok, got activity that looks right. Not sure though.
Here's a screenshot of the histo activity and the parameters of my AFR error PID (which still disappears in the table when loading a log file)

[schpenxel]

I got ya. PE has to be disabled before logging with them, correct?

Gonna try the changes to the afr error and let you know. Thanks

Not unless you want to blow something up, lol

That filter of pid.68=1 is making the fuel trim vs maf histograms only show data while NOT in PE, so those are fine

To tune beyond 85kpa or whatever the PE enable is set to you'll want to run in open loop, reset fuel trims (should do it automatically every flash but can't hurt to check) and then use the afr error vs MAF histogram. Some people just use that one all the time because if fuel trims are disabled you can use it anywhere if the pid is setup correctly.

I'll check out the PID when I get to work and really take a close look at the formula

[schpenxel]

Here's 2 shots of the histogram attempts

And 1 of the PID setings I tried. The default afr error PID wouldn't work. It did at one time.

Alright I've had a chance to look it over

-PID.6001 is afr HIGH resolution. You are (or were) only logging afr LOW resolution, which is different. Add AFR hi-res to the table display so it will be logged
-I don't see any references in the formula to your wideband.. you'll need to figure out what PID your wideband is. It should be something like AUX.20121. Hit the little question mark in the last screenshot you posted and scroll down towards the bottom on the parameters side and find the one you've setup.. I think it will be 20121 but I'm not 100% sure on that
-Try this for your AFR error function just to get you started and see if anything will show up in the histogram (change aux.20121 to whatever your wideband is) : ([AUX.20121]/[PID.6001])
-Let me know what happens. That formula will have to be changed depending on what format you want it to spit out.. some people like it to show up like fuel trims, I usually do it a different way though. My (ok, Greg Banish's DVD method) spits out a multiplier... so 1.00 means your commanded AFR and actual AFR are the same. 1.05 would mean you're actually 5% leaner than the computer is commanded and 0.95 would mean 5% richer than commanded. If this formula works we can change it over to look more like the fuel trim numbers if that's what you want.. this is just simpler to start with

I did add my WB to the PID param. [USER.0006] I think it was. Not home so I can't look at it. I will post it this evening some time.

Gotcha, yeah there's a lot of ways to do it

I think the main problem was you were trying to use the PID for AFR "high" resolution, but were only logging the PID for AFR "low" resolution.

[jpb1972]

Will check that out. Thanks!

Are you using the Beta version or 2.24? I wonder if the upgrade would help me. I can not get a AFR error PID to show up in my primary table. Somethings wrong.

2.24

don't mess with the beta right now.. it's all kinds of a mess right now. tons of features don't work yet

What do you mean? What's it doing? Sorry for asking for so many screenshots but that's the only way I can really help

OK. That's what I thought.
It seems like the config is working for the Histogram, but the PID will not show up in the primary table. The stock AFR error PID doesn't even work (the parameters are grayed out so I cant even change them). I made the custom AFR error PID that seems to provide the correct data for the histogram but like I said, it will not show up in the primary table for some reason.
No problem at all with the screen shots. I will send you as many as you need! Lol

[jpb1972]

Here you can see what is not showing up in the primary table.

[jpb1972]

I was able to get my AFR error (LC-2 AFRerror) to show on the Chart Log only. It's something I guess. I just don't understand why it will not show on the primary table.

Maybe I'm missing something..? It looks like it is working just fine to me. Can you show me the first page of the histogram settings?

Are you trying to get it to show up on the table display window or somewhere else?

yes, I was trying to get the AFR Error PID to show up in one of the primary table boxes. Not a necessity really. I guess i'm good then?

Schpenxel, here's something I came across on methanol.

[jpb1972]

What do I have to do before installing the 3bar map? Do I upload the 2bar is and tune for it first? Have to figure out whether or not to dial in what I have or start messing with the 3bar.

You can just change the map linear and offset values and install the sensor and it'll work. Won't have a boost VE table or anything though

If you go for the 3 bar OS make sure to check the map values before writing everything. On mine HPtuners tried to change the linear/offset values to ones for some sensor I didn't have so I had to change that

You can still run a maf in the 2-3 bar os's too.. It will still work

Thanks I'll read through it

I just changed my MAP settings for the 3 bar and converted the VE coefficients over to the ZL1 values. I do however like the features in the 2 bar OS. I'm still considering that and maybe running it in maf. In this case wouldn't I have to use bluecat to build true VE tables?
