Open Loop BLM?????

[dave w]

I'm trying to understand the "how to" for $OD open loop tuning.

The required .bin changes are listed below?

07/12/2020 20:38:36 Scalar: Minimum BLM changed from 105 BLM (0x69) to 128 BLM (0x80).
07/12/2020 20:38:49 Scalar: Minimum BLM at Idle changed from 90 BLM (0x5A) to 128 BLM (0x80).
07/12/2020 20:38:56 Scalar: BLM Step Value changed from 1 BLM (0x01) to 0 BLM (0x00).
07/12/2020 20:39:06 Scalar: Maximum BLM changed from 165 BLM (0xA5) to 128 BLM (0x80).
07/12/2020 20:39:14 Scalar: Maximum Initial BLM changed from 135 BLM (0x87) to 128 BLM (0x80).
07/12/2020 20:39:24 Scalar: Minimum Initial BLM changed from 126 BLM (0x7E) to 128 BLM (0x80).

Set minimum temperature for closed loop to 151 Celsius?
WBO2 Tune with $OD with Trimanalyzer?
WBO2 Data Log $OD with TunerPro RT?

Everything I could find on the subject, seems to be that all you have to do is change cl minimum temp. Which worked for a while for me, but as I said when I started this thread, I began to notice BLM change without INT change, and while open loop. I have made all the changes you have mentioned, and I think only a couple may be needed, and the rest are just redundant, but I like redundancy anyway. I have not had anymore BLM change.

As far as PE, everything I found said to either disable it, or set it to stoichiometric to get your ve tuned in those cells. But with the trimalizer, it's my understanding that you can leave it on, maybe with the delay, then filter PE to false, and still tune those cells without disabling it. Then after VE is tuned, you can filter PE on, and see how effectively your commanded PE ratio equates to actual lambda.

I'm sure others have a lot more knowledge and experience than I do, as this is my first $od tuning experience, and first attempt at tuning in to a new camshaft as well. Following the summary of everything I have learned has made it possible for me. Ran horrible on stock tune. Wide band was always maxed out full rich at idle. Closed loop open loop, didn't seem to make much difference. And I always thought it should have more power. Now it seems to run better than I'm sure it probably ever did new.

Does TrimAnalyzer filter for Near Idle and Off Idle?

Some rock crawlers like tuning $OD Near Idle for 4 Low Range.

You can set filters for rpm throttle, or flags that are in the data log. Example rpm greater or less than what you specify, or idle flag true or false. Decel enleanment, false and so on.

[ralmo94]

Thought I would show some screenshots of it, since I find it to be a really cool tool

As you can see, I was able to load several logs at once

[ralmo94]

you can select to filter what ever you want as long as its in the data log.
you can search for what you are looking for as I searched for idle flag

[ralmo94]

you can see I also filtered Decel, and PE.

Also, I didn't circle it, but if using wide band, you want to change BLM, to what ever you have it in your adx

Here is what my data log looks like. Notice it doesn't match $OD Ve table.

But you can change that by clicking table layout

As you can see, the program author included a few other VE tables. THanks

[ralmo94]

As you can see, My VE is pretty close according to the information here

[ralmo94]

Here is a really awesome feature of this program.

You can pull up your VE table in Tuner Pro, and copy the table to clip board, then go back to the analyser, and click modify clip board. It changes what you have copied without pasting first. Just go back to tuner pro, and paste. There is your new VE.


I like to go back, and take off all filters except PE, and change it to true, and see if I am getting the ratio I want. Then I can just adjust commanded PE ratio, and leave the VE table alone, taking for granted its close enough.

I just personally discovered this tool the other day, and thought it was really cool. Hope everyone enjoys

seems like you have a pretty good handle on it. i don't think enough people use trimalyzer (me included.. i wrote it but haven't really tuned much with it), maybe your screenshots will help

Does TrimAnalyzer filter for Near Idle and Off Idle?

i kept it really primitive on purpose

it'll filter for whatever you want, as long as whatever you want doesn't involve using 'or' matches. all the filters are 'and' (all must match for a record to be accepted)

it has a 'memory' for your filters but only remembers one custom set

it's worth trying the thing, just load any CSV log into it and play around

one thing worth mentioning though is when tuning really tight areas or special cases, the analysis method (which can be changed on the fly) is important. the (default) mode i call geometric from the UI (actually called radial in the code) is designed for working over an entire VE table by applying the data, especially data requiring heavy trims, to many surrounding cells, and might produce too much blur if you're matching only a small area of the table or working with smaller amounts of log data. for your 'off idle' stuff probably just ues strict cell or whatever and do your own blending by hand

[ralmo94]

Would you need a layout for near idle VE, or would the values be pasted in correct cells no matter what layout is showing? I'm not remembering at the moment, but I'm thinking that's what the warning message is about when you hit modify clipboard data.

If that's the case, would one need to copy the genaric layout and past in a spreadsheet, to use the data, or tune cells manually?

Thanks.

[steveo]

i'm not sure what you're asking

i don't understand what you mean by 'what layout is showing' or why you would have a different layout configured than what your VE table actually is

the function where it takes an entire VE table you have copied and then applies the changes to the clipboard requires the table to be the same size

edit: if you mean you're tuning something other than your primary VE table, then yeah, you need to configure that layout, otherwise the data will be in the wrong place regardless

$OD has two different size VE tables for Near Idle / Off Idle.

The $OD exported .CSV has column "Idle Flag" On / Off

Near Idle data is filtered using Idle Flag = On
