Title: Mbox KFMIOP Interpolator
Post by: berTTos on January 09, 2012, 02:29:21 PM
I saw Master Js post and thought i would share my excel solution for generating KFMIOP for mbox.  It uses VBA to do a linear interpolation to derive KFMIOP values for a given KFMIRL map.

To use -

1. paste in your KFMIRL map.

2. edit the column headers for KFMIOP.  for stage 3 maps I highly recommend raising at least the last 2 columns.  I've been eliminating the first column, shifting existing columns one to the left and increasing the last 3.  I have also found that your maximum KFMIRL load should not exceed your maximum defined KFMIOP column.

3. click Generate KFMIOP map.

I've had great results and this had completely eliminated the dreaded Level 2 Torque Monitoring throttle cut.

where is the kfmiop axis definitions, both x and y?  i know the advanced guys know this but we should add these to the map-packs.  these are linked axis values, right?  what are they linked to?

it's in Nye's XDF.  it's the second 'axis:load(timing)' 0x162E8 in the Timing category and is shared with KFZWOP and KFZWOP2.  on a stage 3 car you can average the first two columns 9.7502 and 18.0004 into a single 13.5003 and this will give you room for more resolution up top without sacrificing much down low.  remember to shift all column data over one column to the left in the 2 OP timing tables that use this axis.

Just some feed back... I've noticed when I filled out IRL your xls didn't fill in the last column at all for IOP... the user Matt Danger had a similar experience except he was missing the top portion (from about the middle up) of the last two columns in IOP.

Not sure what is causing it.

Make sure that your largest KFMIOP column is equal to the largest load request in KFMIRL.  If it's larger then there is nothing to interpolate and an extrapolation would result in a KFMIOP %torque request value of more than 100%.  I think it's also ok to make the largest KFMIOP column slightly smaller than your largest load request in IRL (like .5 smaller).

Let me know if this is the issue.

There's nothing wrong with using VBA to do the 2D/two axis interpolation, but I use a custom function (nicked from the interweb, not my own work on this occasion). See attached file for details. It's very simple to implement if anyone is interested.

hey Berttos - Could you share your KFMIRL with us?  Or at least a methodology for arriving at a good KFMIRL.  I'm not sure the "tuning wizard" generates torque curves relevant to a 2.7tt, maybe I'm wrong?  Please correct me if so.

The tuning wizard doesn't do anything for IRL.

It generates an IOP for a given IRL, which YOU have to decide on... much like your ldrxn

i have observed that it is best to keep the factory curve and simply italian tune the entire table rather than messing with individual columns.  that said - try multiplying all data points by 1.25 - 1.30.

here is what i've been using in my stg 3 file with excellent results ---

I never understood the flat top at the max of pedal position

Why not leave the ENTIRE IRL table stock, and just extend the last 2 columns into the max req load you want?

italian tuning generally yields functional solid results.  however, i'm more a fan of aston martin tuning myself.  lol, jokes aside:  i took the rs4 KFMIRL and here's what i've generated for everyone.  this spreadsheet has an input for your "max power level" and it scales everything appropriately using your italian tuning technique.  i'm going to try it tonight but i feel confident enough that i'll attach the spreadsheet for others to use.  i can't wait to try this out.  i miscalculated this stuff yesterday and got a dreaded L2 intervention, but man was it fun up until that!  hard to believe its the same car honestly...

that's where the wonky timing comes from. strangely and inexplicably - ME7 seems to take the entire table into account when doing load calculations, not just the columns that contain values that would apply to a certain % requested torque in a given situation.  this behavior means that when one greatly increases requested load from one column to another - weird things happen.  i've found that the Torque Monitoring Level 2 will intervene with a throttle cut until a certain load level - then it will intervene via N75 limitation (10% WG duty) - and finally, at the top end, if you make it that far without intervention - it will intervene via timing.

also - i love increased load earlier.  the car is so much more enjoyable this way.  i've tried altering KFPED and a couple of others in place of KFMIRL (light-mid load columns) and found that retaining the stock pedal curve with a completely raised KFMIRL results in a file that is exciting but not unrefined.  for me - it has to pass the wife test - she has to be able to drive it in stop and go traffic.

But if you have IOP set up properly, how does this still happen?

i wish i knew...

perhaps ME7 uses a polynomial interpolation for load calcs rather than a linear?

i do know that i have yet to see a 'professionally tuned' K04 file that properly sets up KFMIOP.  they all seem to do some sort of weird underscaling of MAF values, either via a physically tapered MAF housing or via a tricked out MLHFM in order to trick ME7 into thinking there is a lower load - then they use some fueling tricks to meet actual air intake.  am i crazy? or has no one figured out the relationship between IRL and IOP in all these years?

Something didn't seem to be adding up when I ran your spreadsheet so for the hell of it I took the time and entered in all of your KFMIRL values and your KFMIOP header information and everything matched up perfect except for the last column (attached below).

Am I doing something wrong?

No idea why half of it is purple, lol.

no - you're right.  i've been playing with that last column and trying to understand it's effects on the load calcs throughout the table.  those values are just what i happen to have in there at the moment.  the calculated 'proper' values work fine.  i've yet to determine if they are the absolute best to use.

it means simply turning up the wick for the entire table - all data points * 1.30 for example, without regard for massaging certain load/rpm areas to alter the overall requested load curve.  though, it also refers to FFing an entire table :)

imo the factory got the load curve right for the B5 and it would be hard to improve upon without more resolution in the table (more columns).

 


Title: Re: Mbox KFMIOP Interpolator
Post by: TTQS on January 11, 2012, 02:19:20 PM
Ah right, Italian tuning methodology; just applying the same multiplication factor throughout all addresses without affecting the OEM 'shape'

I suppose you would have to bank on the factory getting it right because they can hold one parameter fixed, e.g. nmot and go right through the rl_w or mrfa_w range on the engine dyno so can tweak response at will.

Thanks for an interesting thread guys. I need to go back and do KFMIOP & KFMIRL 1.01.   ::)

Spreasheet works for me brilliantly. First time for a long time my car is driving butter smooth through all rpms at a given pedal request. I also completely linearized requested pedal torque across rpms/pedal position. I hate the stock curve as if you want to have you car to accelerate constantly, you have keep compensating with pedal by pressing it more and more as the rpms raise, unless you wot ofc.

The car is finally holding the torque without hiccups and heavy handed corrections, A+++++ on this.

As to the shaping of the table and corrections... there are tables in ME 7.1 which have specific notes on them that the ECU is not taking the two most adjacent cells into consideration but is actually "drawing" a curve through five relevant cells and picks a calculated value from that line, not an interpolated value from two adjacent cells.

When you think about it, it makes sense. If the ECU was just interpolating, the derived value would follow a very edgy curve following the values directly. If you draw a curve through multiple cells, it smooths the resulting curve considerably.



I think the note was on

I always presumed that the interpolation was based on the relationship between the entire row or column's values be it linear, power, logarithmic or whatever, not just a simple linear one through two adjacent cell addresses otherwise, as you say, the result would be a jerky response.

I actually recall reading through a random motronic patent regarding the table interpolation method. iirc its a simple low order poly fit done in integer math. There are (iirc) separate routines for 2d and 3d interpolation. I'll bet if we ask nicely setzi might disassemble the interpolation routines for us :)

I'm especially curious to know what happens when you go off the reservation: I'm a assuming it does a hard cap, and does not extrapolate... but i don't know if the cap is smoothed off.

For 2D map interpolation, the ECU does a linear interpolation of the two adjacent cells bounding the test value.
For 3D map interpolation, the ECU does two 2D map interpolations, and then interpolates those two results.

The ECU hard caps the map lookups which go beyond the map range.

That's how it's done in all the older Motronics as well.

Generally Bosch does not part with used traditions easily.
If something works, they use it for a very long time, until there is a compelling reason to switch. They are masters of copy paste.

Thanks,  I did what you suggested and now I am ready for a test run. .. After I get my checksum done. I am still waiting for tuner pro plugin, so if someone can please help me out. .  :) I posted in the checksum request area. Thanks again and can't wait to see if I made progress.

ME7Sum will work with that file.

For some reason I can't use me7checker. I must have a blocker or something. . Ddilenger said something about turning off cookies or something.  I will try again though

As nyet said ME7sum will do it, ive used it countless times and it works without fail

I remember now why I did not look to use Me7Sum.. Everywhere I see it says that it does NOT support ME7.1.1        Is this not the case anymore? Or is the fact that I flashed my file to this R box then it will work now?

M is 7.1
R is 7.1.1

Well test drive complete.  I used the KFMIOP interpreter but I had to make a few adjustments to my table since I had more columns.   In the end, although my end output for kfmiop is 191, the rest of the table is raised  in the AfterSlow pic compared to the BeforeChanges pic.     I am not understanding what happened but I loaded everything just fine. Wnet for a spin and instantly noticed how much lazier the car felt After a couple logs It showed that before I was requesting around 1750-1900 mbar with 940 mbar showing at idle. I was not able to actually hold that much consistently but now with the After tune, Even though both (LDRXN_o_1A, KFMIOP) are raised across the board i am only holding at 1400mbar with the safe 940 at idle.. I am asuuming that I could just subtract whatever my idle mbar is from my load mbar and get actual boost. Anyone able to make sense of this?
The Worst part about this is not having the ability to correct checksums  myself.

Get some good data with ME7logger.

Is duty being restricted?

Your load is still pretty high up top.  NEver going to see that actual load on a k03s.

Have a look at my plots - and this in on a well flowing engine.

Ok, I will give me7logger another try. Yes on k03. Thanks for your logs. I will get back ASAP

I have a question about using this interpolator for best effect:

If I am to "Italian Tune" the entire KMFIRL table by 1.15, what is the appropriate "column header" number modification? Is it necessary to increase KMFIOP "column headers" to more than stock values for better performance, or is Italian tuning KMFIRL sufficient, and then generate KMFIOP from this?

In order for "maximum KMFIRL load should not exceed your maximum defined KFMIOP column", My maximum requested load will be 221.62, and so to keep with berTTos' recommendation, my last KMFIOP column should be 222?

I had a file where the IRL map was changed by my tuner, but he did not update the IOP map. So I used your tool to update IOP, and I have better throttle control in partial throttle conditions! :) Thank you!  8)

I am a SUPER firm believer in the "Keep it simple" approach to IRL/IOP.

Is mine simple or not? What would you recommend I change?

For me, simple means leaving most of the tables stock... There is never a need to rescale all of it.  At most the last two rows.

I think about one thing...I have Leon 210HP and I compare maps KFMIRL,KFMIOP,LDRXN with Leon 225HP and only LDRXN are different.
KFMIRL and KFMIOP have the same values in 210HP and 225HP files.
So when I want more boost maybe only LDRXN I can change and its enough? I have K04 so I can raise it from 0.8bar to 1.2bar?

That's because they are essentially the same engine.

To put I simple, yes LDRXN would be enough for 1.2 bar boost.
But don't forget to get your fuelling sorted.
